Hey guys, simple question probably, i am working on a user registration form and i want their UserName to be spaceless (no spaces), is there a way to put a little OnKeyDown procedure in the username Textfield that will either alert the user when they atempt to hit space or will just not let them hit space


This one alerts when the user attempts to hit anything on the keyboard that isnt a number:

<input type="text" name="numOnly" size="10" onkeypress="if(isNaN(String.fromCharCode(event.keyCode))){alert('Please only enter numbers.');return false;}">


Thanks guys
