How do I prevent numbers to be enter in a textbox ?

am I missing something?  did he state that this was a web page?

Call this javascript function on onkeypress of textbox.

 

function isNumberKey(evt){

     var charCode = (evt.which) ? evt.which : event.keyCode

     if (charCode > 31 && (charCode < 48 || charCode > 57)){

     alert("Please enter digits");

          return false;

      }

      else{   

          return true;

      }   

}
