I\'m trying to read a file with the HTML5 FileReader API. This works fine in Firefox 5.0 but no event is fired in Chromium 12.0.742.112

I'm trying to read a file with the HTML5 FileReader API. This works fine in Firefox 5.0 but no event is fired in Chromium 12.0.742.112

<html>
  <head>
    <script type="text/javascript">
      function handle(evt) {
      var reader = new FileReader();
      var file = evt.files[0];
      console.log("handling: " + file.name);
      reader.onloadstart = function(e) { console.log("loadstart"); }
      reader.onload = function(e) { console.log("onloa开发者_JAVA技巧d"); console.log(e.target.result);  };
      reader.readAsText(file);
      }
    </script>
  </head>
  <body>
    <input type="file" id="input" onchange="handle(this)">
  </body>
</html>

Also the code given in this question Chrome FileReader is not working any more.

My grasp of HTML is rather crude and I cannot see what is wrong with those samples. Is this simply a Chromium bug or is Firefox non-conforming?

I can annotate the sample with ECMAScript5 passages, if this helps and makes things more clear.
