IE6 crashing when using window.location.reload for callback

[glipman]

Within our complex application we use modal dialogs. Sometimes we provide windows.location.reload as callback to refresh the page after closing.

With IE6 and jQuery UI 1.7.2 this has worked fine for two years Recently we upgraded to UI 1.8.14 and now IE6 crashes

Crash IE6 with 1.8.14: ​http://jsfiddle.net/2Gn4w/10/

No problem with 1.7.2: ​http://jsfiddle.net/2Gn4w/7/

Note: it seems the crash occurs even before windows.location.reload is being called, just passing it in is causing the problem.

I do have a workaround: ​http://jsfiddle.net/2Gn4w/10/

function myreload() { windows.location.reload() }

and passing myreload does not crash.

But why is it crashing with 1.8.14 and not with 1.7.2?

Oops: the workaround url should be ​http://jsfiddle.net/2Gn4w/11/

This happens because IE 6 won't let us iterate through window.location.reload, which is done in $.isPlainObject, which is done inside $.widget.extend. I'm not inclined to wrap the $.isPlainObject() call in a try/catch just for this one case.

Just for the record: I doubt a try/catch would help against an application (iexplore.exe) crash.

Good point, we'd have to avoid using $.isPlainObject() and do our own checks.
