title: JavaScript touchstart
body: <p>I have question about 'touchstart' event. I have a button and I want to touch it. So I did 'touschstart' like this:</p>
  
  <pre><code>var button = document.getElementById('btn');   
  button.addEventListener('touchstart', function(){something});
  </code></pre>
  
  <p>The problem is that 'touchstart' makes button clicked only one time. I want button to be 'pressed' all the time when user still touch it. How to do that?</p>
