Jquery binding event on selected class

Your code should work, here's an example of it in action: http://jsfiddle.net/g3GsE/

Make sure that your code is wrapped like this so it doesn't execute until document.ready:

$(function() {
  $('.numonly').bind('keypress',function(event){
    if (event.which > 31 && (event.which < 48 || event.which > 57)) return false;
  });
});

Without this, it would execute immediately and the class="numonly" elements won't be there to find yet...the code needs to wait until document.ready so it fires after the elements are there, so the selector finds them.

Yes this code should work just fine. Just make sure you double check it on the server when submitted. So those who disabled JS can't get around your limitation.
