My site runs on quite a bit of jQuery-based Javascript, and
occasionally I'll receive a complaint from a reader that their browser
goes into an infinite loop and throws a script timeout error, when
they follow a link that takes them away from the page.
I'm assuming this has something to do with jQuery's removal of event
handlers when the page is unloaded; i.e. this code in 1.2.6:
// Prevent memory leaks in IE
// And prevent errors on refresh with events like mouseover in other
browsers
// Window isn't included so as not to unbind existing unload events
jQuery(window).bind("unload", function() {
jQuery("*").add(document).unbind();
});
Today someone complained of seeing this script timeout in Firefox 3.
Is there something I can do to prevent this? There are a lot of
dynamic elements in the site, and event handlers are being installed
on the fly, but I also use the unbind() method before replacing any
HTML and installing new handlers -- so I'm pretty sure there aren't
orphaned bits of event-bound HTML floating around. Any ideas are
welcome...
