 Replacement for windows.onload.
 This fires after the page content (HTML), except images and other binary content, is loaded.

Flexible Javascript Events
http://ejohn.org/projects/flexible-javascript-events/

This library consists of two functions: addEvent and removeEvent. To use them, call it using these methods:

addEvent( object, eventType, function );

The 'object' parameter should be the object upon which you want the event to be called.
The 'eventType' parameter should hold the name of the event, for example: 'click', 'mouseover', 'load', 'submit', etc. More can be found here.
The 'function' parameter should be a reference to a function that you wish to have called whenever the event fires. One parameter will be passed to 'function' - the event object.

Some examples of addEvent in use:

addEvent( document.getElementById('foo'), 'click', doSomething );
addEvent( obj, 'mouseover', function(){ alert('hello!'); } );

removeEvent( object, eventType, function );

removeEvent is virtually identical to addEvent, with the obvious difference: Instead of the function being added to the event handler, it is removed instead. All of the above code and parameters applies to this function.

    obj[type+fn] = function(){obj['e'+type+fn]( window.event );}
