Firefox - infinite loop: 'elem.ownerDocument.defaultView' is null

[smitka]

Some plugins (eg. PrettyPhoto) cause an infinite loop of errors in Firefox (tested on 3.6.4 and 3.6.8).

The problem is on line 4691 (jquery-1.4.2.js):

var defaultView = elem.ownerDocument.defaultView; if ( !defaultView ) { return null; } var computedStyle = defaultView.getComputedStyle( elem, null );

There must be a test if elem.ownerDocument is not null.

Simple workaround is to rewrite code to:

var defaultView = elem.ownerDocument; if ( !defaultView ) { return null; } defaultView=defaultView.defaultView; if ( !defaultView ) { return null; } var computedStyle = defaultView.getComputedStyle( elem, null );

Please reopen with a test case. It sounds like the plugins may be passing invalid information to jQuery methods. If so, the proposed fix will mask those errors and make it harder to debug the code on the page.

harder to debug ? is there anything harder to debug ? i don't think so...
