/**
|
||
|
|
* Provides the ability to hook into any jQuery.fn[method]
|
||
|
|
* with onbeforeMETHOD, onMETHOD, and onafterMETHOD.
|
||
|
|
*
|
||
|
|
* Pass in a string or array of method names you want
|
||
|
|
* to hook with onbefore, on, or onafter.
|
||
|
|
*
|
||
|
|
* Example:
|
||
|
|
* jQuery.hook('show');
|
||
|
|
* jQuery(selector).bind('onbeforeshow', function (e) { alert(e.type);});
|
||
|
|
* jQuery(selector).show() -> alerts 'onbeforeshow'
|
||
|
|
*
|
||
|
|
* jQuery.hook(['show','hide']);
|
||
|
|
* jQuery(selector)
|
||
|
|
* .bind('onbeforeshow', function (e) { alert(e.type);})
|
||
|
|
* .bind('onshow', function (e) { alert(e.type);})
|
||
|
|
* .bind('onaftershow', function (e) { alert(e.type);})
|
||
|
|
* .bind('onafterhide', function (e) { alert("The element is now hidden.");});
|
||
|
|
* jQuery(selector).show().hide()
|
||
|
|
* -> alerts 'onbeforeshow' then alerts 'onshow', then alerts 'onaftershow',
|
||
|
|
* then after the element is hidden alerts 'The element is now hidden.'
|
||
|
|
*
|
||
|
|
*
|
||
|
|
* You can also unhook what you've hooked into by calling jQuery.unhook() passing
|
||
|
|
* in your string or array of method names to unhook.
|
