Selector does not return element

[bleepzter]

In an ASP.NET page I had to display a few products whose id followed the format of "xxxx.xxxx" where "xxxx" was random sequence of letters and numbers generated by the ERP system, all upper case.

For each product I had a text box with Id of "xxxx.xxxx-QTY" as well as a link with an id of "xxxx.xxxx-ADDTOCART"

When trying to access the $('#xxxx.xxxx-QTY').val() always returned undefined because the selector used could not find the right element.

I double and triple checked to make sure all ID's are unique and indeed that was the case.

I tried document.getElementById('xxxx.xxxx-QTY').value and I got the right value from the text box.

I suspect that internally JQuery uses a regular expression to parse out the selectors and the hyphen in the 'xxxx.xxxx-QTY' string is being removed.

Sounds like you need to escape the special chars with \\ in the selector string. If you need more help, ask on the forum before opening a bug report.
