Different behaviour with binding multi eventhandlers pointing to the same function(s) occurs in 1.4.1 and 1.4.2

When binding for example 2 event handlers to an element with both bindings pointing to the same function, there is a different behaviour in 1.4.1 and 1.4.2

in 1.4.1 it seems that the second bind is seen as a duplicated and won't be attached to the dom element. This is exactly what i want. in 1.4.2 both bind are working.

<div id="test" style="height:200px; height:200px; background-color:red;"> </div>


function handleClick() { console.log('click'); } jQuery('#test').bind('click',handleClick);



clicking on it in 1.4.2 results in two logs, in 1.4.1 one.

Please refer to the official jQuery documentation regarding the updates made for the 1.4.2 release with respect to .bind().


The below is an example of the behavior you will experience when defining duplicate event handlers, whether using shorthand or the complete write-up of the bind() code needed.

"As of jQuery 1.4.2 duplicate event handlers can be bound to an element instead of being discarded. For example:

function test(){ alert("Hello"); } $("button").click( test ); $("button").click( test );

The above will generate two alerts when the button is clicked."

Closing ticket as the behavior experienced is something previously agreed upon as being a part of the 1.4.2 jQuery release.
