javascript - Input field allows only numbers and hyphens and within a specific format -


i have following code helps me insure input numbers.

however need restrict number within specific format 0000-00, using sort of alert or maybe return values false or better solution ..

<input type="text" onkeypress='validate(event)' id="class" name="class" maxlength="7" size="15px" placeholder="ex. 1504-03" required>  <script>             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;                 if(theevent.preventdefault) theevent.preventdefault();               }             }         </script>
