Cannot use jQuery 1.3 in XUL pages

[glazou]

This is a regression from 1.2.6 to 1.3. I am using 1.2.6 in BlueGriffon (XUL- and Gecko-based wysiwyg editor) and it works absolutely fine. But attaching jQuery 1.3 to a XUL page results in the following error, horking completely the page's behaviour :

Error: div.firstChild.getAttribute is not a function Line: 2123

This line number is of course in the "development" version, not the minified one.

After doing some digging it looks like this is a very similar issue to #3864.

There is html specific code in jQuery, especially in jQuery.support. I think jQuery is mainly intended for html developers though it's been working quite well with XUL and XML until 1.3. I think XUL developers may need a jquery-xul fork which will definitely become Firefox extension developer's power tool.

This should be fixed now in jQuery rev [6135].

Still not working for me. Firebug says the element created by selectors.js line 702 is of type 'Comment' (nodename '#comment', nodetype 8). It seems that this type of element doesn't support getAttribute(), so the script fails with 'div.firstChild.getAttribute is not a function'. I've attached an amended selectors.js; to wit, I've added '&& div.firstChild.getAttribute' to line 703.

First time I've used Trac, so let me know if I'm Doing It Wrong.

Landed a fix for this in SVN rev [6161]. I just pushed a new nightly as well: ​http://code.jquery.com/nightlies/jquery-2009-01-23.js

There is a special branch of jQuery for use in xul: ​http://www.imaitech.com/jquery-xul/jquery-xul-1.4.5pre-1/jquery-xul.js
