    The event facade for the attribute change

_applyStdModParsedConfig

() private

This method is injected before the _applyParsedConfig step in the application of HTML_PARSER, and sets up the state to identify whether or not we should remove the current DOM content or not, based on whether or not the current content attribute value was extracted from the DOM, or provided by the user configuration

_uiSetFillHeight

(
  • fillSection
)
protected

Updates the rendered UI, to resize the provided section so that the standard module fills out the specified widget height. Note: This method does not check whether or not a height is set on the Widget.

Parameters:

    A valid section specifier - one of WidgetStdMod.HEADER, WidgetStdMod.BODY or WidgetStdMod.FOOTER

_uiSetStdMod

_validateFillHeight

Parameters:

  • val String

    The section which should be setup to fill height, or false/null to disable fillHeight

Returns:

true if valid, false if not

fillHeight

(
  • node
)

Sets the height on the provided header, body or footer element to fill out the height of the Widget. It determines the height of the widgets bounding box, based on it's configured height value, and sets the height of the provided section to fill out any space remaining after the other standard module section heights have been accounted for.

NOTE: This method is not designed to work if an explicit height has not been set on the Widget, since for an "auto" height Widget, the heights of the header/body/footer will drive the height of the Widget.

Parameters:

  • node Node

    The node which should be resized to fill out the height of the Widget bounding box. Should be a standard module section node which belongs to the widget.

getStdModNode

(
  • section
  • forceCreate
)
Node

Returns the node reference for the specified section.

Note: The DOM is not queried for the node reference. The reference stored by the widget instance is returned if it was set. Passing a truthy for forceCreate will create the section node if it does not already exist.

Parameters:

  • section String

    The section whose node reference is required. Either WidgetStdMod.HEADER, WidgetStdMod.BODY, or WidgetStdMod.FOOTER.

  • forceCreate Boolean

    Whether the section node should be created if it does not already exist.

Returns:

Node:

The node reference for the section, or null if not set.

setStdModContent

(
  • section
  • content
  • where
)

Updates the body section of the standard module with the content provided (either an HTML string, or node reference).

This method can be used instead of the corresponding section content attribute if you'd like to retain the current content of the section, and insert content before or after it, by specifying the where argument.

Parameters:

  • section String

    The standard module section whose content is to be updated. Either WidgetStdMod.HEADER, WidgetStdMod.BODY or WidgetStdMod.FOOTER.

  • content String | Node

    The content to be added, either an HTML string or a Node reference.

  • where String

    Optional. Either WidgetStdMod.AFTER, WidgetStdMod.BEFORE or WidgetStdMod.REPLACE. If not provided, the content will replace existing content in the section.
