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'; } };
