jQuery v1.4.2 Internet Explorer Bug

[fowardslash]

On line 116 of the minified version, there is an error which breaks the process in internet explorer.

The current line is:

if(e)f[b]=d;return f[b];

Internet Explorer says:

Invalid argument line 116 character 165

The solution to this problem is:

if(e) return d;

apparently IE doesn't like that f[b] is undefined?

While the solution I proposed does not create an error in internet explorer, it does affect the jquery ui. I'm using the ui dropdown, and the positioning has been effected by not returning f[b]. This line seems to be css related, and quite frankly, it's over my head. I'm going to address the issue via my own stylesheet, however this is a bug for internet explorer when using the jquery ui.

Please reopen with a simple test case that demonstrates the problem. We need to know the *cause* before we look for a solution.

In case that d is equal to "undefinedpx" IE has an error here.

I changed that expression into: if(e&&d!="undefinedpx")f[b]=d;

Now every thing works fine.

You modified the minified version of jQuery??

Submit a reduced test case instead. ​How to report bugs

After modifying also i am getting the same error. Inplace of that i have used if(e) return d; Then i am not getting any error. but the background styles, borders (css) not applied correctly. Please suggest what to do asap.

Instead of 'undefinedpx' just use 'undefined' as the width you are passing might not have 'px' in if(e&&d!="undefinedpx")f[b]=d;
