    Most likely it does not work because you do not have access to the actual filename anymore in a file upload field. On a normal web page you will not be allowed to do this anyway. Perhaps Flash can help you. You should have continued reading http://forums.digitalpoint.com/showthread.php?t=6704 – mplungjan Mar 31 '11 at 11:31

Instead of using ActiveXObject try this with jQuery

For the HTML bellow

<input type="file" id="myFile" />

try the following:

//binds to onchange event of your input field
$('#myFile').bind('change', function() {

  //this.files[0].size gets the size of your file.
  alert(this.files[0].size);

});

See following thread:
