title: Regular expression field validation in jQuery
body: <p>In jQuery, is there a function/plugin which I can use to match a given regular expression in a string?</p>
  
  <p>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?</p>
  
  <p>I've googled for a solution, but I haven't been able to find anything.</p>
