Regular expression field validation in jQuery

Question

In jQuery  is there a function plugin which I can use to match a given regular expression in a string   For example  in an email input box  I get an email address  and want to see if it is in the correct format  What jQuery function should I use to see if my validating regular expression matches the input   I ve googled for a solution  but I haven t been able to find anything

I believe this does it   http   bassistance de jquery-plugins jquery-plugin-validation   It s got built-in patterns for stuff like URLs and e-mail addresses  and I think you can have it use your own as well

If you wanted to search some elements based on a regex  you can use the filter function  For example  say you wanted to make sure that in all the input boxes  the user has only entered numbers  so let s find all the inputs which don t match and highlight them      input text        filter function             return this value match     d                 addClass  inputError       Of course if it was just something like this  you could use the form validation plugin  but this method could be applied to any sort of elements you like  Another example to show what I mean  Find all the elements whose id matches   a-z    d        id    filter function         return this id match   a-z    d
