YUI Library - Event - Release Notes
2.6.0
* Legacy event check for Webkit increased to capture Safari 2.0.3.
* Added add/removeFocusListener, add/removeBlurListener
2.5.2
* Custom Event fire() now throws caught exceptions if YAHOO.util.throwErrors =
true. In either case, a message is written to the logger console.
2.5.1
* Arrays are once again resized when a listener is removed.
* onAvailable/onContentReady stop polling when there is nothing to look for.
2.5.0
* Added try/catch to getTarget to suppress errors when targeting
ActiveX controls.
* Increased the default poll interval to 20ms, and decreased poll
retries to 2000 to reduce IE CPU usage.
* onDOMReady now uses the native DOMContentLoaded event for the
latest releases of WebKit since it support for it was added.
* Restored the code that removes all listeners during the unload event to
address issues caused by the way FireFox persists listeners through
page refreshes.
2.4.1
* Reverted clearAttributes() change to fix IE memory leak on iframes/windows
2.4.0
* getListeners/purgeElement accepts either an element reference or an element id
* onAvailable/onContentReady accepts a single id or an array of ids
* No longer removing listeners during the unload event for non-IE browsers
* IE unload strategy for cross page memory leaks changed from removing each listener
to calling clearAttributes()
* the DOMReady property is now public
* Changed IE onDOMReady approach from the defered script node hack to the doScroll('left') hack
* getCharChode now Remaps SHIFT-TAB key code (25) to TAB (9) in Safari
* getCharCode provides the proper key codes for page up and page down in Safari
* Restored object check to _isValidCollection.
* In KeyListener, added keycode constants for some of the special keys.
* Rolled back the change added for hacking around IE errors from bubbled
events that originally targeted an ActiveX control.
2.3.1
* CustomEvent fire() now catches exceptions thrown by the subscribers so
that the rest of the subscribers execute. The exception is logged and
stored in the "lastError" property.
* Performance tweak: _isValidCollection fails strings first.
* onAvailable/onContentReady will work if an element ref rather than an
id is provided.
* getListeners: fixed the values for the obj and adjust properties.
Added scope property.
* Added IE hack for when the event target is something that can't be
inspected (like a VML canvas). In this case the target is set to
the element the listener is bound to.
2.3.0
* addListener now produces a logger warning if the supplied callback is
undefined.
* Reduced the likelihood that window onload listeners fire before
onAvailable listeners when the two happen near the same moment.
* Fixed an IE error that could occur when the library was injected into
the page after window onload.
* The onDOMReady listener will be executed immediately if the
DOMReady event had already fired prior to the call.
* Unsubscribing custom events within a handler for the event now works
properly.
* EventProvider unsubscribeAll will unsubscribe all listeners from
all hosted custom events if the type is not specified.
* Event.getKeyCode now checks keyCode before charCode for Safari normalization.
Safari arrow key codes are normalized as well.
* Broke up the </script> in Event to allow it to be included inline
2.2.2
* No change
2.2.1
* onAvailable listeners are processed before onContentReady listeners so
they fire in the logical order when an element is found to be available
and ready in the same pass.
* Added onDOMReady for receiving notification when the DOM is first usable.
* In Internet Explorer, onAvailable/onContentReady checks now start when
DOMReady fires to reduce the possibility of receiving an "operation
aborted" errors when inserting DOM nodes during in the onAvailable/
onContentReady listener execution.
* CustomEvent subscribers supplying undefined callbacks will be notified
when subscribing rather than having an ambiguous error thrown when the
event is fired.
* Fixed missing html tags in the examples.
* POLL_INTERVAL is 10 ms.
* YAHOO.util.CustomEvent is now declared before YAHOO.util.Event.
2.2.0
* YAHOO.util.KeyListener was moved from the container package into event.
* The Safari bug that made it so preventDefault would not work with click
and double-click listeners on anchor tags was resolved in version 2.0.4.
The workaround (using DOM0 events for these instead of the normal DOM2
events) is now only used for releases prior to 2.0.4.
* getListeners/purgeElement now work correctly with unload listeners
* When legacyEvents are used (Safari<2.0.4 click events), if there was an
existing DOM0 event that the utility replaced, it is executed along with
the listeners that were added with the utility.
* Restored Event.regCE for compatibility with a beta release of the library
that in use in an external API.
* unsubscribe in CustomEvent and EventProvider will remove all listeners
if the listener is omitted.
* Added unsubscribeAll to EventProvider
* Added Event.lastError which stores the most recent error object if
a browser-specific add/remove listener call throws an exception.
0.12.2
* Fixed a bug introduced in 0.12.1 release caused nested onAvailable
calls to fail.
0.12.1
* If an error is thrown during the browser-specific add/remove lister call,
addListener/removeListener will catch the error and return false.
* onAvailable array items are nulled out instead of deleted when completed to
get around an Opera issue introduced in a recent version of the browser.
0.12.0
* If the function argument is not provided to Event.removeListener, all
all listeners for the specified event type on the element will be removed.
* CustomEvent now has an optional parameter that defines the signature of
the listeners for this event. 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).
