I'm using jQuery 1.3.2 in an Firefox extension but I keep getting the error "div is null" on line 940.

I'm loading jQuery like this in my chrome overlay:

<script type="application/x-javascript"

Can you provide a complete test case? It's not possible to reproduce the problem with only the information provided.

comment:2 Changed 14 years ago by acoder

I can no longer reproduce the error so you should probably close this bug.

I'm experiencing the same thing. It's limited to the use of jquery UI functions. So, for example,

Add a wrapper: foo.wrapper= $('<div id="foo">').appendTo(masthead).html("&nbsp;");

Pull in some html. . no problem. $(foo.wrapper).load("http://foobar.com/foo.html", "", rebind);

Add some CSS in the callback (rebind), no problem. $(foo.wrapper).css("border","3px solid red");

Fade the Div out in the callback, no problem. $(serum.wrapper).fadeOut("slow");

Do anything at all related to jqueryUI, and bork. The attached error can be caught (see attached image), but if the statement isn't wrapped in a try catch, everything just dies.

$(serum.wrapper).accordion(); Nogo.

$(serum.wrapper).tabs(); / Same problem.

We're calling 1.3.2 in the chrome overlay as well, but from a remote spot. I've tried calling it from different locations (the hosted Google instances here: http://code.google.com/apis/ajaxlibs/documentation/index.html#jquery for example) and run into the same issue.

Worthy of note. . When I run the nightly build instead of 1.3.2, this problem is resolved. I've confirmed by toggling between builds that the issue has been resolved somewhere between 1.3.2 and the head. .

I have the same issue trying to use .append() in my extension with jQuery 1.3.2

test case for #4352

This bug seems to exist in both the 1.3.2 and nightly (2009-03-22 21:55:17 -0400 (Sun, 22 Mar 2009)) releases.

To replicate this bug it is probably worthwhile to set up a firefox extension environment (https://developer.mozilla.org/en/Setting_up_extension_development_environment)

Unzip the attached test-case (bug-4352-testcase.zip), then create a file called '[email protected]…' with the contents being the full path to this test-case i.e. '/home/dan/bug-4352/', make sure to place this file in your mozilla extensions directory

The bug is exposed on line 9 of bug-4352.js, which causes line 940 of jquery (1.3.2) to output 'div is null' to the error console, here is the jquery line throwing the error:

elem = jQuery.makeArray(div.childNodes);

If any more info is required, ask away.

Alas- I'm running into this again. This time in line 2304, not sure if the line is significant. Tried updating to a nightly build, still fails. I'll attach the stack returned when I capture the error with a try/catch.

Worthy of note. .

Line 2304, where the code fails, is

elem = jQuery.makeArray(div.childNodes);

(see dmachera's comment above. . )

Summary: "div is null" when used with XULSupport $("string") in XUL
Type: bugenhancement

The $(html) constructor is meant to parse HTML (not XML or XUL):


jQuery uses the innerHTML property of a div to convert an HTML string to DOM nodes. It doesn't appear that XUL supports innerHTML so you can't use $(html) and would need to create the nodes via DOM or a plugin. Here's what I found:



I've edited this ticket to change it to an enhancement request.

Resolution: wontfix
Status: newclosed

This doesn't seem like a feature we'd ever include in core; the best way to support this would be through a XUL plugin.
