Your keyVal assignment didn't take all browsers into account. This piece of code works in Firefox, IE7, Safari, Chrome and won't let you type numbers in the field, tested with a normal text input element:

$().ready(function(){
  $(".textbox").keypress(function(event){
    var keyVal = (event.charCode ? event.charCode : ((event.keyCode) ? event.keyCode : event.which));
      if((keyVal > 48 && keyVal < 57))// Numbers
      {
         return false;
      }
    });
});
