jQuery Forum

Can you reproduce the problem/bug in jsfiddle.net? It sounds like maybe you're sending a function the wrong arguments (perhaps using an old signature?)

Hey Dan,
I really appreciate the quick response. I know this might be a long-shot, but I have attached the site.js file that powers the site. Let me know if that helps at all or if there's anything I can do to help resolve this. The code is being run in a members-only portal site (built in ASPX). Thanks!

Would anyone be able to help me with this? I'd really appreciate some help. Thank you very much.

Well, I can tell you that IE seems to be having an issue at line 5980 in the non-minimized jQuery file (https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.js). It seems to be failing on the first regular expression test on that line, but IE's error messages have a tendency to be a bit vague, so I can't say for sure. I can't imagine what would be causing an invalid argument error with the test() function, I don't personally know of anything that would cause it a problem like this.

I put your site.js into jshint.com and received tons of errors. I'd make sure it passes that before moving forward.

Hey,
Thank you very much everyone for your help with this. Dan - I put the site.js file into jshint.com and made the proper corrections - thanks for that.

As far as the jQuery issue - I had another developer look at it and he seems to think this may actually be a core jQuery bug (which he was able to fix). Basically, on line 5970 (uncompressed debug version of 1.5.1) there is a function that grabs an element's style and converts any integer values that are not set to px, to px (so em to px, etc). What this function does though is look for a single value, but in my expression, I had padding, so it was:

1. padding: 14px 12px 120px 12px;     

So, it was interpreting my padding value of 14px 12px 120px 12px as one value, which was throwing up an error. I first corrected my errors and tested the regular jQuery but had the same result.

So, all in all, things are fixed, but with a modified jQuery version. This is the modification of the function:

1. if ( document.documentElement.currentStyle ) {
       currentStyle = function( elem, name ) {
           var left,
               ret = elem.currentStyle && elem.currentStyle[ name ],
               rsLeft = elem.runtimeStyle && elem.runtimeStyle[ name ],
               style = elem.style;

           // If we're not dealing with a regular pixel number
           // but a number that has a weird ending, we need to convert it to pixels
           if ( !rnumpx.test( ret ) && rnum.test( ret ) ) {
               // Remember the original values
               left = style.left;
   
               // Put in the new values to get a computed value out
               if ( rsLeft ) {
                   elem.runtimeStyle.left = elem.currentStyle.left;
               }
               try
               { style.left = name === "fontSize" ? "1em" : (ret || 0);
               }
               catch(objError)
               {
               }
               finally
               { ret = style.pixelLeft + "px";
                 // Revert the changed values
                 style.left = left;
                 if ( rsLeft ) { elem.runtimeStyle.left = rsLeft; }
               }
           }
           return ret === "" ? "auto" : ret;
       };
   }
