title: Adding a JavaScript alert on the input type file prevents the open file dialog from appearing in Internet Explorer
body: <p>I have an input type, ="file". When I try to put <code>onclick = "alert('test')";</code>, it shows in both Internet&nbsp;Explorer and Firefox, but in Internet&nbsp;Explorer after I press the OK button, the message will disappear and nothing happens, in Firefox: after the message disappears, the open file dialog appears as normal. How can I show the open file dialog in Internet&nbsp;Explorer after the JavaScript message disappears?</p>
  
  <p>As for Internet&nbsp;Explorer, I am using <a href="http://en.wikipedia.org/wiki/Internet_Explorer_9" rel="nofollow">Internet&nbsp;Explorer&nbsp;9</a>.</p>
