Just get rid of it.

1. $(function () {
2.         $(".expandCollapse").click(function () {
3.             //Some code here
4.         });
5. });

I get an undefined error if I try to assign a click event when there's no instances on the page.

I'm sure I never used to have add lines in to check first. Perhaps there's been a change somewhere alone the line in the library itself to make it necessary to check first.

I can't seem to reproduce creating a simple test page. I wonder if it's down to the shear size of the page and IE6's crummy JavaScript support. The page where the error happens contains a very large and complex SVG based image editing embed (hence I can't even test in FF or Chrome).

Once loaded there's 2MB worth of JavaScript and 10MB+ of SVG loaded. I could be hitting some limit somewhere that stops jQuery being able to reliably query the dom.

I guess for now I'll have to stick with the Try/Catch block until I can convince the business to get the staff onto a more recent browser with better JavaScript debugging tools.
