title: Javascript & "onclickstart"
body: <p>I've searched a lot for a Javascript event which shows a situation
  that a click has been started but not finished yet. For example for
  <code>ondrag</code> event there's an <code>ondragstart</code>. I didn't find anything useful...</p>
  
  <p>so here's the question:</p>
  
  <p>Is there a <code>onclickstart</code> event in Javascript? 
  If the answer is "No", how could it be implemented? </p>
  
  <p>I appreciate your comments.</p>
