Prevent html input type file from showing open dialog
To make a long story short, I need to be able to prevent the default action from a input type="file". In other words I do not want to display the system's open dialog box when the user clicks on the "Browse" or "Choose File". I already have the replacement dialog working, but the system's open dialog box still appears.
Below is a sample of what I am currently trying to accomplish this. (PS: I am using Chrome 21)
<html>
<head>
<script type="text/javascript">
<!--
file_onclick = function()
{
// Show custom dialog instead...
event.stopPropagation(); // Doesn't work
return false; // Neither does this
};
//-->
</script>
</head>
<body>
<input type="file" onclick="javascript: file_onclick();" />
</body>
</html>
Any ideas?

Got it. I needed to disable the tag and then use the setTimeout method to re-enable it.
<html>
<head>
<script type="text/javascript">
<!--
file_onclick = function(o)
{
// Show custom dialog instead...
o.disabled = true;
setTimeout(function() { o.disabled = false; }, 1);
};
//-->
</script>
</head>
<body>
<input type="file" onclick="javascript: file_onclick(this);" />
</body>
</html>
