• JQuery is a final option if we donot have any other solution. Problem is - we should not view the file upload control. While IE donot allow a multi part form to be programatically submitted. – Ranjan Sarma Commented Nov 26, 2012 at 10:51

If you set the display to none, it won't work in webkit browsers. But you can set the opacity, width and height to zero, and then call the click event when the other button is clicked.

Here is a working example http://jsfiddle/jcVL5/

***Edit: I just saw "the file should get uploaded to the server". You will have to explain what server side language you are using.

<input type="file" id="fileUpload" style="opacity:0; height:0px;width:0px;" />
<input type="button" id="btnUpload" value="test Button" />​

<script>
document.getElementById('btnUpload').onclick = function(){
    document.getElementById('fileUpload').click();
};​
</script>

Have you tried using Fine Uploader? You can see the demo site here http://fineuploader. if this is what you need.
