title: Disable the default function when tap a while on the Ipad safari browser
body: <p>Default keeping tap on the screen (eg. hold tap for 1 second) will <strong>show a option of save image / copy</strong>. However , I would like to turn off that function for my web app , is it possible? I have tried to replace the event of touchmove to selectall , however it does not work . Thanks for helping.</p>
  
  <pre><code>addEventListener('touchmove', function(e) { e.preventDefault(); }, true);
  </code></pre>
