# Mouse Wheel ChangeLog
|
||||
|
||||
# 3.0
|
||||
|
||||
* Uses new special events API in jQuery 1.2.2+
|
||||
* You can now treat "mousewheel" as a normal event and use .bind, .unbind and .trigger
|
||||
* Using jQuery.data API for expandos
|
||||
|
||||
|
||||
# 2.2
|
||||
|
||||
* Fixed pageX, pageY, clientX and clientY event properties for Mozilla based browsers
|
||||
|
||||
|
||||
# 2.1.1
|
||||
|
||||
* Updated to work with jQuery 1.1.3
|
||||
* Used one instead of bind to do unload event for clean up.
|
||||
|
||||
|
||||
# 2.1
|
||||
|
||||
* Fixed an issue with the unload handler
|
||||
|
||||
|
||||
# 2.0
|
||||
|
||||
* Major reduction in code size and complexity (internals have change a whole lot)
|
||||
|
||||
|
||||
# 1.0
|
||||
|
||||
* Fixed Opera issue
|
||||
* Fixed an issue with children elements that also have a mousewheel handler
|
||||
* Added ability to handle multiple handlers
