pasted event - fires when user paste event has completed

provides value before and after paste via prevVal and newVal properties on event object
uses onpaste event internally
adds support for Opera which does not support onpaste natively
- limited to inputs and textareas (won't fire on other nodes set with contenteditable)

Listen for event on any input[type=text], input[type=password], textarea, or element with contenteditable set. Passing a boolean arg of true instructs the event to only fire if the paste changed the value of the element ('value' property for inputs and textareas, 'textContent' for other elements).

Code Sample

<script src="http://yui.yahooapis.com/3.2.0 PR1/build/yui/yui-min.js"></script>

YUI({
    //Last Gallery Build of this module
    gallery: 'gallery-2010.08.11-20-39'
}).use('gallery-event-pasted', function(Y) {
    var onPasted = function(evt) {
        alert('pasted!\n\nwas: "' + evt.prevVal + '"\n\nnow: "' + evt.newVal + '"');
    };
 
    // fire when any text is pasted into textfield
    Y.one('#mytextarea').on('pasted', onPasted);
 
    // fire only if pasted text changed field's value
    Y.one('#mytextarea2').on('pasted', onPasted, null, true);
});
