Bug 16813 – REGRESSION: TypeError: Undefined value loading mootools JavaScript causes page content to fail to load

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: New Bugs

[Cameo Wood]

This page crashes in current Safari release, and content doesn't load correctly in ToT.

I see a bunch of JS errors in the console when loading that page.  They're almost certainly why the Flash content doesn't load correctly.

[Adam Roben (:aroben)]

The page seems to load correctly in Firefox 3b1 and IE7.

This happens with TOT on Leopard too.  System Safari crashes when loading the page, much like Safari 3.0.4 on Windows.

TypeError: Undefined value
http://mootools.net/assets/scripts/mootools.js?v=1 (line 8)

This is also reproducible when loading http://mootools.net/.

[Mark Rowe (bdash)]

The mootools code triggering the exception is:

if (typeof HTMLElement == 'undefined'){
	var HTMLElement = function(){};
	if (window.webkit) document.createElement("iframe"); //fixes safari
	HTMLElement.prototype = (window.webkit) ? window["[[DOMElement.prototype]]"] : {};
}
HTMLElement.prototype.htmlElement = function(){};

This means that this bug is a dupe of 16644, which even looks like it deals with mootools!
