Here is the JavaScript you can use in your web application

function validKeyStroke(key) {
   switch (key) {
      case 9:
         return false;
      break;
      case 37:
         return false;
      break;
      case 38:
         return false;
      break;
      case 39:
         return false;
      break;
      case 40:
         return false;
      break;
      default:
         return true;
   }
};
function chgColor() {
   if (validKeyStroke(window.event.keyCode)) {
         window.event.srcElement.style.backgroundColor = '#ADD6FF';
   }
};
