title: Mobile keyboard does not open with Javascript focus event
body: <p>Trying to focus a simple input text when page loads with Javascript events, my goal is to focus and open the virtual keyboard on mobile browsers but I've not gotten success. </p>
  
  <p>My code looks like so simple as:</p>
  
  <pre><code>document.getElementById("anser-animation").focus();
  document.getElementById("anser-animation").click();
  </code></pre>
  
  <p>I've tried on jQuery as well...</p>
  
  <pre><code>$('#answer-animation').focus();
  $('#answer-animation').trigger('click');
  </code></pre>
  
  <p>On android input gets focus but not on iPhones. On both cases I don't get the keyboard intermediately on page loading. I'm not sure what's more I have to do.</p>
