Binding to change event nulls event object in IE9

Description

Firstly, here's the scenario:

  • an ASP.net 3.5 web form with standard ASP.net validation
  • jQuery 1.6.2
  • a custom 'change' event handler that is bound to a textarea on the form:

$("textarea").bind("change keyup keydown", function() {

// Monitor character count

}).trigger("change");

If using IE9, the internal ASP.net validation script throws the following error:

SCRIPT5007: Unable to get value of the property 'srcElement': object is null or undefined

WebResource.axd?d=W-BIdqaeNBPdzou...

against the following lines of script:

if (!event) {

event = window.event;

}

var targetedControl;

if ((typeof(event.srcElement) != "undefined") && (event.srcElement != null)) {

targetedControl = event.srcElement;

}

...

}

The problem did/does not exist with jQuery 1.5.2

I don't think the problem is related to the ASP.net validation per se, it just happens to be the scenario that exposed the problem.

It 'appears' that in binding to the change event, IE somehow nulls the/loses reference to the window.event object - but my debugging skills are not sufficient to determine this - sorry.

I am having the exact same problem as described by this ticket.

It is occuring only in IE9 --

I identified the same code cited in the original ticket above as the culprit. We are using jQuery 1.8.3.

As per above, the actual code that fails is in the ScriptResources.axd file and the method argument (event) is null. So javascript errors out and no additional javascript is executed.
