Jquery 1.6.1 min issue in IE7/IE8

Reported by: Owned by:
Priority: low Milestone:
Component: core Version: 1.6.1
Keywords: Cc:
Blocked by: Blocking:

The minified version of JQuery (such as the one located here: ) causes an error in IE7 and IE8 compatability modes. IE9 is fine. Another machine, possibly with a different set of DLLs (e.g. jscript.dll) doesn't have the issue. Swapping jscript.dll doesn't fix it (so there are possibly other IE-related dlls that are also different).

Only the minified version is affected. Changing to use the non-minified version of 1.6 does not error.

A simple test page is:



<script src=""></script>








IE's developer tools say:

Object doesn't support this property or method, line 16 character 18206. The debugger stops on a statement that says:


at this point, variable b is a function that says:

function b(){j.noCloneEvent=!1,a.detachEvent("onclick",b)}

Thanks for taking the time to contribute to the jQuery project!

This is working fine. You probably need a document ready.

No, it was a problem with the actual 1.6.1 minified js BEFORE any jquery commands were executed on the page.

I noticed I was still running IE9 beta. Upgrading to the full version has fixed the problem, so anyone else that ever runs into a similar issue should just update their IE9.

I got the same problem on development. not-minified works fine.
