Pjax Class

Extends Router
Defined in: pjax/js/pjax.js:58
Module: pjax

Available since 3.5.0

Provides seamless, gracefully degrading Pjax (pushState + Ajax) functionality, which makes it easy to progressively enhance standard links on the page so that they can be loaded normally in old browsers, or via Ajax (with HTML5 history support) in newer browsers.

Constructor

Pjax

(
  • [config]
)

Defined in pjax/js/pjax.js:58

Available since 3.5.0

Parameters:

  • [config] Object optional

    Config attributes.

Item Index

Methods

_addAttrs

(
  • cfgs
  • values
  • lazy
)
private

Implementation behind the public addAttrs method.

This method is invoked directly by get if it encounters a scenario in which an attribute's valueFn attempts to obtain the value an attribute in the same group of attributes, which has not yet been added (on demand initialization).

Parameters:

  • cfgs Object

    An object with attribute name/configuration pairs.

  • values Object

    An object with attribute name/value pairs, defining the initial values to apply. Values defined in the cfgs argument will be over-written by values in this argument unless defined as read only.

  • lazy Boolean

    Whether or not to delay the intialization of these attributes until the first call to get/set. Individual attributes can over-ride this behavior by defining a lazyAdd configuration property in their configuration. See addAttr.

_addLazyAttr

(
  • name
  • [lazyCfg]
)
private

Finishes initializing an attribute which has been lazily added.

Parameters:

  • name Object

    The name of the attribute

  • [lazyCfg] Object optional

    Optional config hash for the attribute. This is added for performance along the critical path, where the calling method has already obtained lazy config from state.

_addOutOfOrder

(
  • name
  • cfg
)
private

Utility method used by get/set to add attributes encountered out of order when calling addAttrs().

For example, if:

this.addAttrs({
                 foo: {
                     setter: function() {
                        // make sure this bar is available when foo is added
                        this.get("bar");
                     }
                 },
                 bar: {
                     value: ...
                 }
            });

Parameters:

  • name String

    attribute name

  • cfg Object

    attribute configuration

_afterHistoryChange

(
  • e
)
protected

Inherited from Router: app/js/router.js:1600

Handles history:change and hashchange events.

Parameters:

_aggregateAttrs

(
  • allAttrs
)
Object private

A helper method, used by _initHierarchyData to aggregate attribute configuration across the instances class hierarchy.

The method will protect the attribute configuration value to protect the statically defined default value in ATTRS if required (if the value is an object literal, array or the attribute configuration has cloneDefaultValue set to shallow or deep).

Parameters:

  • allAttrs Array

    An array of ATTRS definitions across classes in the hierarchy (subclass first, Base last)

Returns:

Object:

The aggregate set of ATTRS definitions for the instance

_attrCfgHash

() private

Utility method to define the attribute hash used to filter/whitelist property mixes for this class for iteration performance reasons.

_baseDestroy

() private

Internal destroy implementation for BaseCore

_baseInit

() private

Internal initialization implementation for BaseCore

_cloneDefaultValue

(
  • cfg
)
private

This method assumes that the value has already been checked to be an object. Since it's on a critical path, we don't want to re-do the check.

Parameters:

_decode

(
  • string
)
String protected

Inherited from Router: app/js/router.js:765

Wrapper around decodeURIComponent that also converts + chars into spaces.

Parameters:

  • string String

Utility method to normalize attribute values. The base implementation simply merges the hash to protect the original.

Parameters:

  • valueHash Object

    An object with attribute name/value pairs

Returns:

An object literal with 2 properties - "simple" and "complex", containing simple and complex attribute values respectively keyed by the top level attribute name, or null, if valueHash is falsey.

_onLinkClick

(
  • e
)
protected

Inherited from PjaxBase: pjax/js/pjax-base.js:316

Available since 3.5.0

Handler for delegated link-click events which match the linkSelector.

This will attempt to enhance the navigation to the link element's href by passing the URL to the _navigate() method. When the navigation is being enhanced, the default action is prevented.

If the user clicks a link with the middle/right mouse buttons, or is holding down the Ctrl or Command keys, this method's behavior is not applied and allows the native behavior to occur. Similarly, if the router is not capable or handling the URL because no route-handlers match, the link click will behave natively.

Parameters:

() protected chainable

Inherited from Router: app/js/router.js:1336

Queues up a _save() call to run after all previously-queued calls have finished.

This is necessary because if we make multiple _save() calls before the first call gets dispatched, then both calls will dispatch to the last call's URL.

All arguments passed to _queue() will be passed on to _save() when the queued function is executed.

Inherited from Router: app/js/router.js:1381

Available since 3.5.0

Returns the normalized result of resolving the path against the current path. Falsy values for path will return just the current path.

Parameters:

  • path String

    URL path to resolve.

Returns:

String:

Resolved path.

_resolveURL

(
  • url
)
String protected

Inherited from Router: app/js/router.js:1403

Available since 3.5.0

Resolves the specified URL against the current URL.

This method resolves URLs like a browser does and will always return an absolute URL. When the specified URL is already absolute, it is assumed to be fully resolved and is simply returned as is. Scheme-relative URLs are prefixed with the current protocol. Relative URLs are giving the current URL's origin and are resolved and normalized against the current path root.

Parameters:

Returns:

String:

Resolved URL.

_save

(
  • [url]
  • [replace=false]
)
protected chainable

Inherited from Router: app/js/router.js:1454

Saves a history entry using either pushState() or the location hash.

This method enforces the same-origin security constraint; attempting to save a url that is not from the same origin as the current URL will result in an error.

Parameters:

  • [url] String optional

    URL for the history entry.

  • [replace=false] Boolean optional

    If true, the current history entry will be replaced instead of a new one being added.

_set

  • name
  • val
  • [opts]
)
Object protected chainable

Allows setting of readOnly/writeOnce attributes. See set for argument details.

Parameters:

  • name String

    The name of the attribute.

  • val Any

    The value to set the attribute to.

A reference to the host object.

_setAttrs

(
  • attrs
  • [opts]
)

Returns:

String:

The upgraded URL, or the specified URL untouched.

Example:

addAttr

(
  • name
  • config
  • lazy
)
Object chainable

Adds an attribute with the provided configuration to the host object.

The config argument object supports the following properties:

value <Any>
The initial value to set on the attribute
valueFn <Function | String>

A function, which will return the initial value to set on the attribute. This is useful for cases where the attribute configuration is defined statically, but needs to reference the host instance ("this") to obtain an initial value. If both the value and valueFn properties are defined, the value returned by the valueFn has precedence over the value property, unless it returns undefined, in which case the value property is used.

valueFn can also be set to a string, representing the name of the instance method to be used to retrieve the value.

readOnly <boolean>
Whether or not the attribute is read only. Attributes having readOnly set to true cannot be modified by invoking the set method.
writeOnce <boolean> or <string>
Whether or not the attribute is "write once". Attributes having writeOnce set to true, can only have their values set once, be it through the default configuration, constructor configuration arguments, or by invoking set.

The writeOnce attribute can also be set to the string "initOnly", in which case the attribute can only be set during initialization (when used with Base, this means it can only be set during construction)

setter <Function | String>

The setter function used to massage or normalize the value passed to the set method for the attribute. The value returned by the setter will be the final stored value. Returning Attribute.INVALID_VALUE, from the setter will prevent the value from being stored.

setter can also be set to a string, representing the name of the instance method to be used as the setter function.

getter <Function | String>

The getter function used to massage or normalize the value returned by the get method for the attribute. The value returned by the getter function is the value which will be returned to the user when they invoke get.

getter can also be set to a string, representing the name of the instance method to be used as the getter function.

validator <Function | String>

The validator function invoked prior to setting the stored value. Returning false from the validator function will prevent the value from being stored.

validator can also be set to a string, representing the name of the instance method to be used as the validator function.

lazyAdd <boolean>
Whether or not to delay initialization of the attribute until the first call to get/set it. This flag can be used to over-ride lazy initialization on a per attribute basis, when adding multiple attributes through the addAttrs method.

The setter, getter and validator are invoked with the value and name passed in as the first and second arguments, and with the context ("this") set to the host object.

Configuration properties outside of the list mentioned above are considered private properties used internally by attribute, and are not intended for public use.

Parameters:

  • name String

    The name of the attribute.

  • config Object

    An object with attribute configuration property/value pairs, specifying the configuration for the attribute.

    NOTE: The configuration object is modified when adding an attribute, so if you need to protect the original values, you will need to merge the object.

  • lazy Boolean

    (optional) Whether or not to add this attribute lazily (on the first call to get/set).

Returns:

Object:

A reference to the host object.

addAttrs

(
  • cfgs
  • values
  • lazy
)
Object chainable

Configures a group of attributes, and sets initial values.

NOTE: This method does not isolate the configuration object by merging/cloning. The caller is responsible for merging/cloning the configuration object if required.

Parameters:

  • cfgs Object

    An object with attribute name/configuration pairs.

  • values Object

    An object with attribute name/value pairs, defining the initial values to apply. Values defined in the cfgs argument will be over-written by values in this argument unless defined as read only.

  • lazy Boolean

    Whether or not to delay the intialization of these attributes until the first call to get/set. Individual attributes can over-ride this behavior by defining a lazyAdd configuration property in their configuration. See addAttr.

Returns:

Object:

A reference to the host object.

addTarget

(
  • o
)
chainable

Registers another EventTarget as a bubble target. Bubble order is determined by the order registered. Multiple targets can be specified.

Events can only bubble if emitFacade is true.

Included in the event-custom-complex submodule.

Parameters:

after

(
  • type
  • fn
  • [context]
  • [arg*]
)
EventHandle

Parameters:

  • type String

    The name of the event

  • fn Function

    The callback to execute in response to the event

  • [context] Object optional

    Override this object in callback

  • [arg*] Any optional

    0..n additional arguments to supply to the subscriber

Returns:

EventHandle:

A subscription handle capable of detaching the subscription

attrAdded

(
  • name
)
Boolean

Checks if the given attribute has been added to the host

Parameters:

  • name String

    The name of the attribute to check.

Returns:

Boolean:

true if an attribute with the given name has been added, false if it hasn't. This method will return true for lazily added attributes.

before

()

Executes the callback before a DOM event, custom event or method. If the first argument is a function, it is assumed the target is a method. For DOM and custom events, this is an alias for Y.on.

For DOM and custom events: type, callback, context, 0-n arguments

For methods: callback, object (method host), methodName, context, 0-n arguments

Returns:

detach handle

bubble

(
  • evt
)
Boolean

Propagate an event. Requires the event-custom-complex module.

Parameters:

Returns:

Boolean:

the aggregated return value from Event.Custom.fire

destroy

() BaseCore chainable

Inherited from BaseObservable but overwritten in base/js/BaseCore.js:352

Destroy lifecycle method. Invokes destructors for the class hierarchy.

Returns:

BaseCore:

A reference to this object

detach

(
  • type
  • fn
  • context
)
EventTarget

Detach one or more listeners the from the specified event

Parameters:

  • type String | Object

    Either the handle to the subscriber or the type of event. If the type is not specified, it will attempt to remove the listener from all hosted events.

  • fn Function

    The subscribed function to unsubscribe, if not supplied, all subscribers will be removed.

  • context Object

    The custom object passed to subscribe. This is optional, but if supplied will be used to disambiguate multiple listeners that are the same (e.g., you subscribe many object using a function that lives on the prototype)

Returns:

EventTarget:

the host

detachAll

(
  • type
)

Removes all listeners from the specified event. If the event type is not specified, all listeners from all hosted custom events will be removed.

Parameters:

  • type String

    The type, or name of the event

dispatch

() chainable

Inherited from Router: app/js/router.js:244

Dispatches to the first route handler that matches the current URL, if any.

If dispatch() is called before the ready event has fired, it will automatically wait for the ready event before dispatching. Otherwise it will dispatch immediately.

fire

(
  • type
  • arguments
)
Boolean

Fire a custom event by name. The callback functions will be executed from the context specified when the event was created, and with the following parameters.

The first argument is the event type, and any additional arguments are passed to the listeners as parameters. If the first of these is an object literal, and the event is configured to emit an event facade, that object is mixed into the event facade and the facade is provided in place of the original object.

If the custom event object hasn't been created, then the event hasn't been published and it has no subscribers. For performance sake, we immediate exit in this case. This means the event won't bubble, so if the intention is that a bubble target be notified, the event must be published on this object first.

Parameters:

  • type String | Object

    The type of the event, or an object that contains a 'type' property.

  • arguments Object*

    an arbitrary set of parameters to pass to the handler. If the first of these is an object literal and the event is configured to emit an event facade, the event facade will replace that parameter after the properties the object literal contains are copied to the event facade.

Returns:

Boolean:

True if the whole lifecycle of the event went through, false if at any point the event propagation was halted.

get

(
  • name
)
Any

Returns the current value of the attribute. If the attribute has been configured with a 'getter' function, this method will delegate to the 'getter' to obtain the value of the attribute.

Parameters:

  • name String

    The name of the attribute. If the value of the attribute is an Object, dot notation can be used to obtain the value of a property of the object (e.g. get("x.y.z"))

Returns:

Any:

The value of the attribute

getAttrs

(
  • attrs
)
Object

Gets multiple attribute values.

Parameters:

  • attrs String[] | Boolean

    Optional. An array of attribute names. If omitted, all attribute values are returned. If set to true, all attributes modified from their initial values are returned.

Returns:

Object:

An object with attribute name/value pairs.

getContent

The return value is an object containing two properties:

  • node: A Y.Node instance for a document fragment containing the extracted HTML content.

  • title: The title of the HTML page, if any, extracted using the titleSelector attribute (which defaults to looking for a <title> element). If titleSelector is not set or if a title could not be found, this property will be undefined.

Returns:

EventTarget[]

hasRoute

(
  • url
)
Boolean

Inherited from Router: app/js/router.js:281

Returns true if this router has at least one route that matches the specified URL, false otherwise. This also checks that any named param handlers also accept app param values in the url.

This method enforces the same-origin security constraint on the specified url; any URL which is not from the same origin as the current URL will always return false.

Parameters:

Returns:

Boolean:

init

(
  • cfg
)
BaseCore chainable

loadContent

(
  • req
  • res
  • next
)

Inherited from PjaxContent: pjax/js/pjax-content.js:83

Available since 3.7.0

Pjax route middleware to load content from a server. This makes an Ajax request for the requested URL, parses the returned content and puts it on the route's response object.

This is route middleware and not intended to be the final callback for a route. This will add the following information to the route's request and response objects:

  • req.ioURL: The full URL that was used to make the Y.io() XHR. This may contain "pjax=1" if the addPjaxParam option is set.

  • res.content: An object containing node and title properties for the content extracted from the server's response. See getContent() for more details.

  • res.ioResponse: The full Y.io() response object. This is useful if you need access to the XHR's response status or HTTP headers.

Parameters:

  • req Object

    Request object.

  • res Object

    Response Object.

  • next Function

    Function to pass control to the next route callback.

Example:

router.route('/foo/', 'loadContent', function (req, res, next) {
                Y.one('container').setHTML(res.content.node);
                Y.config.doc.title = res.content.title;
            });

match

(
  • path
)
Object[]

Inherited from Router: app/js/router.js:328

Returns an array of route objects that match the specified URL path.

If this router has a root, then the specified path must be semantically within the root path to match any routes.

This method is called internally to determine which routes match the current path whenever the URL changes. You may override it if you want to customize the route matching logic, although this usually shouldn't be necessary.

Each returned route object has the following properties:

  • callback: A function or a string representing the name of a function this router that should be executed when the route is triggered.

  • keys: An array of strings representing the named parameters defined in the route's path specification, if any.

  • path: The route's path specification, which may be either a string or a regex.

  • regex: A regular expression version of the route's path specification. This regex is used to determine whether the route matches a given path.

Parameters:

  • path String

    URL path to match. This should be an absolute path that starts with a slash: "/".

Returns:

Object[]:

Array of route objects that match the specified path.

Example:

router.route('/foo', function () {});
            router.match('/foo');
            // => [{callback: ..., keys: [], path: '/foo', regex: ...}]

modifyAttr

(
  • name
  • config
)

Updates the configuration of an attribute which has already been added.

The properties which can be modified through this interface are limited to the following subset of attributes, which can be safely modified after a value has already been set on the attribute:

readOnly;
writeOnce;
broadcast; and
getter.

Note: New attributes cannot be added using this interface. New attributes must be added using addAttr, or an appropriate manner for a class which utilises Attributes (e.g. the ATTRS property in Base).

Parameters:

  • name String

    The name of the attribute whose configuration is to be updated.

  • config Object

    An object with configuration property/value pairs, specifying the configuration properties to modify.

navigate

(
  • url
  • [options]
)
Boolean

Inherited from PjaxBase: pjax/js/pjax-base.js:98

Available since 3.5.0

Navigates to the specified URL if there is a route handler that matches. In browsers capable of using HTML5 history, the navigation will be enhanced by firing the navigate event and having the router handle the "request". Non-HTML5 browsers will navigate to the new URL via manipulation of window.location.

When there is a route handler for the specified URL and it is being navigated to, this method will return true, otherwise it will return false.

Note: The specified URL must be of the same origin as the current URL, otherwise an error will be logged and navigation will not occur. This is intended as both a security constraint and a purposely imposed limitation as it does not make sense to tell the router to navigate to a URL on a different scheme, host, or port.

Parameters:

  • url String

    The URL to navigate to. This must be of the same origin as the current URL.

  • [options] Object optional

    Additional options to configure the navigation. These are mixed into the navigate event facade.

    • [replace] Boolean optional

      Whether or not the current history entry will be replaced, or a new entry will be created. Will default to true if the specified url is the same as the current URL.

    • [force=false] Boolean optional

      Whether the enhanced navigation should occur even in browsers without HTML5 history.

Returns:

Boolean:

true if the URL was navigated to, false otherwise.

on

(
  • type
  • fn
  • [context]
  • [arg*]
)
EventHandle

Subscribe a callback function to a custom event fired by this object or from an object that bubbles its events to this object.

 this.on("change", this._onChange, this);

Callback functions for events published with emitFacade = true will receive an EventFacade as the first argument (typically named "e"). These callbacks can then call e.preventDefault() to disable the behavior published to that event's defaultFn. See the EventFacade API for all available properties and methods. Subscribers to non-emitFacade events will receive the arguments passed to fire() after the event name.

To subscribe to multiple events at once, pass an object as the first argument, where the key:value pairs correspond to the eventName:callback.

 this.on({
                 "attrChange" : this._onAttrChange,
                 "change"     : this._onChange
             });

You can also pass an array of event names as the first argument to subscribe to all listed events with the same callback.

 this.on([ "change", "attrChange" ], this._onChange);

Returning false from a callback is supported as an alternative to calling e.preventDefault(); e.stopPropagation();. However, it is recommended to use the event methods whenever possible.

Parameters:

  • type String

    The name of the event

  • fn Function

    The callback to execute in response to the event

  • [context] Object optional

    Override this object in callback

  • [arg*] Any optional

    0..n additional arguments to supply to the subscriber

Returns:

EventHandle:

A subscription handle capable of detaching that subscription

once

(
  • type
  • fn
  • [context]
  • [arg*]
)
EventHandle

Listen to a custom event hosted by this object one time. This is the equivalent to on except the listener is immediatelly detached when it is executed.

Parameters:

  • type String

    The name of the event

  • fn Function

    The callback to execute in response to the event

  • [context] Object optional

    Override this object in callback

  • [arg*] Any optional

    0..n additional arguments to supply to the subscriber

Returns:

EventHandle:

A subscription handle capable of detaching the subscription

onceAfter

(
  • type
  • fn
  • [context]
  • [arg*]

    0..n additional arguments to supply to the subscriber

Returns:

EventHandle:

A subscription handle capable of detaching that subscription

param

(
  • name
  • handler
)
chainable

Inherited from Router: app/js/router.js:383

Available since 3.12.0

Adds a handler for a route param specified by name.

Param handlers can be registered via this method and are used to validate/format values of named params in routes before dispatching to the route's handler functions. Using param handlers allows routes to defined using string paths which allows for req.params to use named params, but still applying extra validation or formatting to the param values parsed from the URL.

If a param handler regex or function returns a value of false, null, undefined, or NaN, the current route will not match and be skipped. All other return values will be used in place of the original param value parsed from the URL.

Parameters:

  • name String

    Name of the param used in route paths.

  • handler Function | RegExp

    Function to invoke or regular expression to exec() during route dispatching whose return value is used as the new param value. Values of false, null, undefined, or NaN will cause the current route to not match and be skipped. When a function is specified, it will be invoked in the context of this instance with the following parameters:

    • value String

      The current param value parsed from the URL.

    • name String

      The name of the param.

Example:

router.param('postId', function (value) {
                return parseInt(value, 10);
            });
            
            router.param('username', /^\w+$/);
            
            router.route('/posts/:postId', function (req) {
                Y.log('Post: ' + req.params.id);
            });
            
            router.route('/users/:username', function (req) {
                // req.params.username is an array because the result of calling
                // exec() on the regex is assigned as the param's value.
                Y.log('User: ' + req.params.username[0]);
            });
            
            router.route('*', function () {
                Y.log('Catch-all no routes matched!');
            });
            
            // URLs which match routes:
            router.save('/posts/1');     // => "Post: 1"
            router.save('/users/ericf'); // => "User: ericf"
            
            // URLs which do not match routes because params fail validation:
            router.save('/posts/a');            // => "Catch-all no routes matched!"
            router.save('/users/ericf,rgrove'); // => "Catch-all no routes matched!"

Parameters:

replace

(

)
chainable

Inherited from Router: app/js/router.js:489

Replaces the current browser history entry with a new one, and dispatches to the first matching route handler, if any.

Behind the scenes, this method uses HTML5 pushState() in browsers that support it (or the location hash in older browsers and IE) to change the URL.

The specified URL must share the same origin (i.e., protocol, host, and port) as the current page, or an error will occur.

Parameters:

  • [url] String optional

    URL to set. This URL needs to be of the same origin as the current URL. This can be a URL relative to the router's root attribute. If no URL is specified, the page's current URL will be used.

Example:

// Starting URL: http://example.com/
            
            router.replace('/path/');
            // New URL: http://example.com/path/
            
            router.replace('/path?foo=bar');
            // New URL: http://example.com/path?foo=bar
            
            router.replace('/');
            // New URL: http://example.com/

Parameters:

  • name String

    Optional. The name of the attribute to reset. If omitted, all attributes are reset.

Returns:

Object:

A reference to the host object.

route

(
  • route
  • callbacks
)
chainable

Inherited from Router: app/js/router.js:523

Adds a route handler for the specified route.

The route parameter may be a string or regular expression to represent a URL path, or a route object. If it's a string (which is most common), it may contain named parameters: :param will match any single part of a URL path (not including / characters), and param will match any number of parts of a URL path (including / characters). These named parameters will be made available as keys on the req.params object that's passed to route handlers.

If the route parameter is a regex, all pattern matches will be made available as numbered keys on req.params, starting with 0 for the full match, then 1 for the first subpattern match, and so on.

Alternatively, an object can be provided to represent the route and it may contain a path property which is a string or regular expression which causes the route to be process as described above. If the route object already contains a regex or regexp property, the route will be considered fully-processed and will be associated with any callacks specified on the object and those specified as parameters to this method. Note: Any additional data contained on the route object will be preserved.

Here's a set of sample routes along with URL paths that they match:

  • Route: /photos/:tag/:page

    • URL: /photos/kittens/1, params: {tag: 'kittens', page: '1'}
    • URL: /photos/puppies/2, params: {tag: 'puppies', page: '2'}
  • Route: /file/path

    • URL: /file/foo/bar/baz.txt, params: {path: 'foo/bar/baz.txt'}
    • URL: /file/foo, params: {path: 'foo'}

Middleware: Routes also support an arbitrary number of callback functions. This allows you to easily reuse parts of your route-handling code with different route. This method is liberal in how it processes the specified callbacks, you can specify them as separate arguments, or as arrays, or both.

If multiple route match a given URL, they will be executed in the order they were added. The first route that was added will be the first to be executed.

Passing Control: Invoking the next() function within a route callback will pass control to the next callback function (if any) or route handler (if any). If a value is passed to next(), it's assumed to be an error, therefore stopping the dispatch chain, unless that value is: "route", which is special case and dispatching will skip to the next route handler. This allows middleware to skip any remaining middleware for a particular route.

Parameters:

  • route String | RegExp | Object

    Route to match. May be a string or a regular expression, or a route object.

  • callbacks Array | Function | String multiple

    Callback functions to call whenever this route is triggered. These can be specified as separate arguments, or in arrays, or both. If a callback is specified as a string, the named function will be called on this router instance.

    • req Object

      Request object containing information about the request. It contains the following properties.

      • params Array | Object
        Captured parameters matched by the route path specification. If a string path was used and contained named parameters, then this will be a key/value hash mapping parameter names to their matched values. If a regex path was used, this will be an array of subpattern matches starting at index 0 for the full match, then 1 for the first subpattern match, and so on.
      • path String
        The current URL path.
      • pendingCallbacks Number
        Number of remaining callbacks the route handler has after this one in the dispatch chain.
      • pendingRoutes Number
        Number of matching routes after this one in the dispatch chain.
      • query Object
        Query hash representing the URL query string, if any. Parameter names are keys, and are mapped to parameter values.
      • route Object
        Reference to the current route object whose callbacks are being dispatched.
      • router Object
        Reference to this router instance.
      • src String
        What initiated the dispatch. In an HTML5 browser, when the back/forward buttons are used, this property will have a value of "popstate". When the dispath() method is called, the src will be "dispatch".
      • url String
        The full URL.
    • res Object

      Response object containing methods and information that relate to responding to a request. It contains the following properties.

      • req Object
        Reference to the request object.
    • next Function

      Function to pass control to the next callback or the next matching route if no more callbacks (middleware) exist for the current route handler. If you don't call this function, then no further callbacks or route handlers will be executed, even if there are more that match. If you do call this function, then the next callback (if any) or matching route handler (if any) will be called. All of these functions will receive the same req and res objects that were passed to this route (so you can use these objects to pass data along to subsequent callbacks and routes).

      • [err] String optional
        Optional error which will stop the dispatch chaining for this req, unless the value is "route", which is special cased to jump skip past any callbacks for the current route and pass control the next route handler.

Example:

router.route('/photos/:tag/:page', function (req, res, next) {
                Y.log('Current tag: ' + req.params.tag);
                Y.log('Current page number: ' + req.params.page);
            });
            
            // Using middleware.
            
            router.findUser = function (req, res, next) {
                req.user = this.get('users').findById(req.params.user);
                next();
            };
            
            router.route('/users/:user', 'findUser', function (req, res, next) {
                // The findUser middleware puts the user object on the req.
                Y.log('Current user:' req.user.get('name'));
            });

save

(
  • [url]
)
chainable

Inherited from Router: app/js/router.js:699

Saves a new browser history entry and dispatches to the first matching route handler, if any.

Behind the scenes, this method uses HTML5 pushState() in browsers that support it (or the location hash in older browsers and IE) to change the URL and create a history entry.

The specified URL must share the same origin (i.e., protocol, host, and port) as the current page, or an error will occur.

Parameters:

addPjaxParam

Boolean

Inherited from PjaxContent: pjax/js/pjax-content.js:204

Available since 3.5.0

If true, a "pjax=1" query parameter will be appended to all URLs requested via Pjax.

Browsers ignore HTTP request headers when caching content, so if the same URL is used to request a partial Pjax page and a full page, the browser will cache them under the same key and may later load the cached partial page when the user actually requests a full page (or vice versa).

To prevent this, we can add a bogus query parameter to the URL so that Pjax URLs will always be cached separately from non-Pjax URLs.

Default: true

linkSelector

String | Function

Inherited from PjaxBase: pjax/js/pjax-base.js:372

Available since 3.5.0

CSS selector string used to filter link click events so that only the links which match it will have the enhanced navigation behavior of Pjax applied.

When a link is clicked and that link matches this selector, Pjax will attempt to dispatch to any route handlers matching the link's href URL. If HTML5 history is not supported or if no route handlers match, the link click will be handled by the browser just like any old link.

By default Pjax allows the browser to perform its default action when a user is navigating within a page by clicking in-page links (e.g. <a href="#top">Top of page</a>) and does not attempt to interfere or enhance in-page navigation.

Default: false

Fires event navigateOnHashChange

Fires when the value for the configuration attribute navigateOnHash is changed. You can listen for the event using the on method if you wish to be notified before the attribute's value has changed, or using the after method if you wish to be notified after the attribute's value has changed.

Map of params handlers in the form: name -> RegExp | Function.

If a param handler regex or function returns a value of false, null, undefined, or NaN, the current route will not match and be skipped. All other return values will be used in place of the original param value parsed from the URL.

This attribute is intended to be used to set params at init time, or to completely reset all params after init. To add params after init without resetting all existing params, use the param() method.

Default: `{}`

Fires event paramsChange

Fires when the value for the configuration attribute params is changed. You can listen for the event using the on method if you wish to be notified before the attribute's value has changed, or using the after method if you wish to be notified after the attribute's value has changed.

Parameters:

  • e EventFacade
    An Event Facade object with the following attribute-specific properties added:
    • prevVal Any
      The value of the attribute, prior to it being set.
    • newVal Any
      The value the attribute is to be set to.
    • attrName String
      The name of the attribute being set.
    • subAttrName String

root

String

Inherited from Router: app/js/router.js:1695

Absolute root path from which all routes should be evaluated.

For example, if your router is running on a page at http://example.com/myapp/ and you add a route with the path /, your route will never execute, because the path will always be preceded by /myapp. Setting root to /myapp would cause all routes to be evaluated relative to that root URL, so the / route would then execute when the user browses to http://example.com/myapp/.

Default: `''`

Fires event rootChange

Fires when the value for the configuration attribute root is changed. You can listen for the event using the on method if you wish to be notified before the attribute's value has changed, or using the after method if you wish to be notified after the attribute's value has changed.

Parameters:

  • e EventFacade

routes

Object[]

Inherited from Router: app/js/router.js:1723

Array of route objects.

Each item in the array must be an object with the following properties in order to be processed by the router:

  • path: String or regex representing the path to match. See the docs for the route() method for more details.

  • callbacks: Function or a string representing the name of a function on this router instance that should be called when the route is triggered. An array of functions and/or strings may also be provided. See the docs for the route() method for more details.

If a route object contains a regex or regexp property, or if its path is a regular express, then the route will be considered to be fully-processed. Any fully-processed routes may contain the following properties:

  • regex: The regular expression representing the path to match, this property may also be named regexp for greater compatibility.

  • keys: Array of named path parameters used to populate req.params objects when dispatching to route handlers.

Any additional data contained on these route objects will be retained. This is useful to store extra metadata about a route; e.g., a name to give routes logical names.

This attribute is intended to be used to set routes at init time, or to completely reset all routes after init. To add routes after init without resetting all existing routes, use the route() method.

Default: `[]`

Events

destroy

Lifecycle event for the destroy phase, fired prior to destruction. Invoking the preventDefault method on the event object provided to subscribers will prevent destruction from proceeding.

Subscribers to the "after" moment of this event, will be notified after destruction is complete (and as a result cannot prevent destruction).

Event Payload:

error

Defined in pjax/js/pjax.js:22

Available since 3.5.0

Fired when an error occurs while attempting to load a URL via Ajax.

Event Payload:

  • content Object

    Content extracted from the response, if any.

    • node Node

      A Y.Node instance for a document fragment containing the extracted HTML content.

    • [title] String optional

      The title of the HTML page, if any, extracted using the titleSelector attribute. If titleSelector is not set or if a title could not be found, this property will be undefined.

  • responseText String

    Raw Ajax response text.

  • status Number

    HTTP status code for the Ajax response.

  • url String

    The absolute URL that failed to load.

init

Lifecycle event for the init phase, fired prior to initialization. Invoking the preventDefault() method on the event object provided to subscribers will prevent initialization from occuring.

Subscribers to the "after" momemt of this event, will be notified after initialization of the object is complete (and therefore cannot prevent initialization).

Event Payload:

  • e EventFacade

    Event object, with a cfg property which refers to the configuration object passed to the constructor.

load

Defined in pjax/js/pjax.js:40

Available since 3.5.0

Fired when a URL is successfully loaded via Ajax.

Event Payload:

  • content Object

    Content extracted from the response, if any.

    • node Node

      A Y.Node instance for a document fragment containing the extracted HTML content.

    • [title] String optional

      The title of the HTML page, if any, extracted using the titleSelector attribute. If titleSelector is not set or if a title could not be found, this property will be undefined.

  • responseText String

    Raw Ajax response text.

  • status Number

    HTTP status code for the Ajax response.

  • url String

    The absolute URL that was loaded.

navigate

Inherited from PjaxBase: pjax/js/pjax-base.js:16

Available since 3.5.0

Fired when navigating to a URL via Pjax.

When the navigate() method is called or a pjax link is clicked, this event will be fired if the browser supports HTML5 history and the router has a route handler for the specified URL.

This is a useful event to listen to for adding a visual loading indicator while the route handlers are busy handling the URL change.

Event Payload:

  • url String

    The URL that the router will dispatch to its route handlers in order to fulfill the enhanced navigation "request".

  • [force=false] Boolean optional

    Whether the enhanced navigation should occur even in browsers without HTML5 history.

  • [hash] String optional

    The hash-fragment (including "#") of the url. This will be present when the url differs from the current URL only by its hash and navigateOnHash has been set to true.

  • [originEvent] Event optional

    The event that caused the navigation. Usually this would be a click event from a "pjax" anchor element.

  • [replace] Boolean optional

    Whether or not the current history entry will be replaced, or a new entry will be created. Will default to true if the specified url is the same as the current URL.

ready

Inherited from Router: app/js/router.js:26

Fired when the router is ready to begin dispatching to route handlers.

You shouldn't need to wait for this event unless you plan to implement some kind of custom dispatching logic. It's used internally in order to avoid dispatching to an initial route if a browser history change occurs first.

Event Payload:

  • dispatched Boolean

    true if routes have already been dispatched (most likely due to a history change).
