title: HTML5 pattern for formatting input box to take date mm/dd/yyyy?
body: <p>I used jQuery datepicker and I want to restrict my input field with a HTML5 pattern if a user, instead of getting the date from jQuery datepicker, types the date. </p>
  
  <p>How can I restrict my users with a HTML5 pattern so that they can just type the date in the form <code>mm/dd/yyyy</code>?</p>
