title: Block typing in any other alphabet than english
body: <p>I know the JavaScript that restricts entering some special characters or number, etc using charcode and ascii value.</p>
  
  <p>Is there anyway that I can block people entering any other language (I mean alphabet) expect English? More specifically how can I block people entering Chinese or some other non English alphabet name in the textbox and make them strictly enter only English alphabet name?</p>
  
  <p>Thanks</p>
