Sizzle calling into attachEvent breaks IE11

Description

This bug affects IE11 and the following code within jQuery:

// Support: IE>8
// If iframe document is assigned to "document" variable and if iframe has been reloaded,
// IE will throw "permission denied" error when accessing "document" variable, see jQuery #13936
if ( parent && parent.frameElement ) {
  parent.attachEvent( "onbeforeunload", function() {
    setDocument();
  });
}

The code assumes that the "attachEvent" method will be available, which as of IE11, it is not. If the code is even still required, it should be using "addEventListener".

This is easily reproducible by simply IFRAME-ing a page that uses jQuery. I've created a jsfiddle that demonstrates it here:

http://jsfiddle.net/Pxnqr/. You'll need to run that using IE11 with the debugger attached and breaking on errors.

The problem happens before that, you can see that parent.frameElement gives the "Access is denied" error before it even gets to the .attachEvent() call.

Sorry that's likely just a same-origin policy bug with with example since the JavaScript can't access objects across different domains. Although that's maybe a separate issue with the code in question. :)

If you had an example where both the parent window and the page inside the iframe were both on the same domain, that should cause the problem.

This is easily reproducible

Could you create an example that frames a jsfiddle/jsbin page? You can add "/show" to a jsfiddle URL to just show the page without the editing UI.

Ok, I've updated the jsfiddle to use two pages on the same domain using the /show/ flag as you suggested. It's now breaking on the "attachEvent" exception instead of the "access denied" one.

Try this guy out: http://jsfiddle.net/Pxnqr/3/show/

Are you sure you got the jQuery version right? This was fixed in 1.10.2 by #13980. I haven't checked if IE11 also exhibits the root issue, but we're no longer accessing frameElement.

You're correct, I was using 1.10.1 which is all that jsfiddle supports. Switching it manually to 1.10.2 resolves the issue (http://jsfiddle.net/Pxnqr/5/show/) and looking at the code I can see that the affected block has been modified.

@dmethvin, thanks for the prompt attention on this one. You'll likely see more of this issue from sites using pre-1.10.2 once IE11 goes into the wild. But feel free to close this ticket! :)

Duplicate of #13980.It looks like IE11 will continue to throw the cross-window access exception, but unfortunately it can't be isolated with attachEvent like IE9/10: http://builds.jenkins.jquery.com/jquery/9bf6aaf4adcd4b4e5ff6e2b5ae6a239d52a1bddc/test/index.html?module=Sizzle

simply add a function called attachEvent inside the iframe, and assign the addEventListener - like this (before jQuery script tag in IFRAME):

var isIE11 = !!(navigator.userAgent.match(/Trident/) && !navigator.userAgent.match(/MSIE/));

if (isIE11) {

if (typeof window.attachEvent == "undefined" || !window.attachEvent)

window.attachEvent = window.addEventListener;

}
