- Requiring at least one field

I am using for my form validations.

I want to use this script

However I want the input to be a "number" field instead of a "text" field. When I change to a number field it doesn't work correctly. Any idea why and what do I need to change?

Instead of this you can set
<input type='text' onkeypress='validate(event)' />

Open in new window

function validate(evt) {
  var theEvent = evt || window.event;
  var key = theEvent.keyCode || theEvent.which;
  key = String.fromCharCode( key );
  var regex = /[0-9]|\./;
  if( !regex.test(key) ) {
    theEvent.returnValue = false;

Thanks for that, but I would like the number increment/decrement if possible. Is it not possible to get the script work using a number type instead?
