Two signatures are supported: - - YAHOO.util.CustomEvent.LIST: - param1: event name - param2: array of arguments provided to fire() - param3: <optional> the custom object supplied to subscribe() - - YAHOO.util.CustomEvent.FLAT: - param1: the first argument provided to fire() - param2: <optional> the custom object supplied to subscribe() - - The new flat signature makes it possible to provide a better API - when using custom events, and it makes it possible to transparently - wrap DOM events. - - * The parameters for overriding scope in both Event.addListener, and - CustomEvent.subscribe have been augmented. In addition to the - previous behavior where a true value would make the previous parameter - the execution scope, an object can be supplied instead. If an object - is provided, that object becomes the scope obj. This makes it possible - to pass a both a custom object and adjust the scope to a different object. - - * Added EventProvider, which is a wrapper for CustomEvent that makes it - possible to subscribe to events by name, whether or not the event has - been created. This class was designed to be used with YAHOO.augment. - EventProvider custom events are created with the new FLAT listener - signature. - - * CustomEvent subscribers can return false to stop the propagation of - the event. - - * CustomEvents now have an onSubscribe custom event that can used to the - case where a subscriber subscribes to an one-time event that has already - happened. Also provides a way for the implementer to defer initialization - logic until after the first subscription. - - * Event.getCharCode now always returns keyCode if charCode is not available. - - * Added Event.onContentReady, which is similar to onAvailable, but it also - checks simblings to try to determine when the element's children are - available. - -0.11.4 - - * Fixed a memory leak in IE6 that occurred when the utility was hosted in - an iframe. - - * Fixed an issue with Safari click listeners when listeners were removed. - -0.11.3 - - * The listener cache is now pruned when events are removed. This fixes - a performance issue when adding many listeners, removing them, and - adding them again repeatedly. - - * Safari click listeners will work correctly if a bound element is removed - from the DOM and a new element with the same ID is added. - - * Removed the code that automatically unsubscribed custom event listeners. - -0.11.0 - - * Added Event.purgeElement which will remove all listeners added via - addListener from the supplied element. If an optional "type" parameter - is supplied, only events of that type will be removed. Optionally, the - purge can be performed recursively on the element's children as well. - - * Added Event.getListeners which will return all listeners attached to - a given element.. either all listeners or listeners of a specific type. - - * getTarget now automatically resolves text nodes. The optional parameter - for this feature is now deprecated. - - * getRelatedTarget now resolves text nodes for the browsers that return the - text node rather than its host HTML element. - - * CustomEvent now logs the custom event activity if the logger widget is available - -0.10.0 - - * Added Safari dblclick to the list of legacy events. - - * When multiple identical event handlers are defined, multiple calls - to removeListener can now remove all of them. - - * removeListener works properly for unload events - - * Legacy event bookkeeping is more efficient, improving the performance for - adding Safari click events. - - * _unload() is more efficient, improving the page transition experience in - Safari in particular. - - * addListener, removeListener now return false if the function argument is - not valid. - - * Fixed an operator precedence issue in getCharCode. - - * Added Event.getXY, which returns [Event.getPageX(e), Event.getPageY(e)] - - * Added Event.onAvailable, which will execute the callback when the element - with the supplied id is found. Currently searches periodically until the - window load event or for up to 10 seconds after the onAvailable method - was executed. - - * The lazy listener attachment process now will poll beyond the window load - event in order to better handle the case when a listener is defined - late in the page but before the element is in the dom. - - * Fixed browser detection for Opera installations reporting as IE. - - * It is now possible to remove and re-add legacy events (Safari click event). - diff --git a/reports/site_media/yui/event/event-debug.js b/reports/site_media/yui/event/event-debug.js deleted file mode 100644 index 468e592e7..000000000 --- a/reports/site_media/yui/event/event-debug.js +++ /dev/null @@ -1,1797 +0,0 @@ -/* -Copyright (c) 2006, Yahoo!
