How to check for comma separated values in  a text box and raise an alert if not found.
And there is should be characters in it like A,B,C,D
  function validate()
   {
         //validate text box;
   }
  <input type="text" id="val" >A,B,C,D</input>
  <input type="button" id="save" onclick="validate()">  
Thanks.
