How to handle ajax file upload

I tried with below code,
<browser>
function unsetFile (el, url) {
    if (!url) url = (_sahi.isBlankOrNull(el.form.action) || (typeof el.form.action != "string")) ? _sahi.getWindow(el).location.href : el.form.action;
    if (url && (q = url.indexOf("?")) != -1) url = url.substring(0, q);
    if (url.indexOf("http") != 0) {
        var loc = window.location;
        if (url.indexOf("/") == 0){
            url = loc.protocol+ "//" +  loc.hostname + (loc.port ? (':'+loc.port) : '') + url;
        }else{
            var winUrl = loc.href;
            url = winUrl.substring(0, winUrl.lastIndexOf ('/') + 1) + url;
        }
    }
    _sahi._removeMock(url.replace(/[.]/g, "[.]"));
};
</browser>
_call(unsetFile(_file("dealImage")));
_setFile(_file("dealImage"), "image5.png");
if (_isIE()){
    _call(_file("dealImage").outerHTML = _file("dealImage").outerHTML.replace(/type=file/, "type=text"));
}else{
    _call(_file("dealImage").type = "text");
}
_setValue(_textbox("dealImage"), "image5.png");

but it returns error : 
_call(unsetFile(_file("dealImage")));
TypeError: el.form is null

OS : Windows XP
Browser : Mozilla 3.6.6

Thanks in advance

    Hi Jeeson,

    File upload should work the same way as it would without AJAX.
    Have you looked at _setFile?

    Do you get the same error when you run the script without _call(unsetFile(_file("dealImage")));? If yes, is it possible for you to point us to your application or a similar example available online? We could try reproducing the problem and give you a solution.

    Hi Dkulkarni,
    Thanks for your reply.

    Yes, same error on without _call(unsetFile(_file("dealImage")));

    Image uploader in our application is similar to http://www.webinfopedia.com/demo/ajax-dynamic-image-upload/

    Thanks

    At last I tried with mouse movement using java.
    photo_upload();

function photo_upload () {
    var robot = new java.awt.Robot();
    robot.keyPress(java.awt.event.KeyEvent.VK_END);    
    
    var mouseX=java.awt.Toolkit.getDefaultToolkit().getScreenSize().getWidth() ;
    var mouseY=java.awt.Toolkit.getDefaultToolkit().getScreenSize().getHeight(); 
    
    var mouseX=450;
    var mouseY=700;    
    robot.mouseMove(mouseX, mouseY);     
    robot.mousePress(java.awt.event.InputEvent.BUTTON1_MASK);
    robot.mouseRelease(java.awt.event.InputEvent.BUTTON1_MASK);
    robot.delay(2000);
    
    mouseX=50;
    mouseY=250;    
    robot.mouseMove(mouseX, mouseY);    
    robot.mousePress(java.awt.event.InputEvent.BUTTON1_MASK);
    robot.mouseRelease(java.awt.event.InputEvent.BUTTON1_MASK);
    robot.delay(2000);
    
    mouseX=150;
    mouseY=120;    
    robot.mouseMove(mouseX, mouseY);    
    robot.mousePress(java.awt.event.InputEvent.BUTTON1_MASK);
    robot.mouseRelease(java.awt.event.InputEvent.BUTTON1_MASK);
    robot.mousePress(java.awt.event.InputEvent.BUTTON1_MASK);
    robot.mouseRelease(java.awt.event.InputEvent.BUTTON1_MASK);
    robot.delay(2000);
    
    mouseX=250;
    mouseY=120;    
    robot.mouseMove(mouseX, mouseY);    
    robot.mousePress(java.awt.event.InputEvent.BUTTON1_MASK);
    robot.mouseRelease(java.awt.event.InputEvent.BUTTON1_MASK);
    robot.mousePress(java.awt.event.InputEvent.BUTTON1_MASK);
    robot.mouseRelease(java.awt.event.InputEvent.BUTTON1_MASK);
    robot.delay(2000);
    
    mouseX=150;
    mouseY=120;    
    robot.mouseMove(mouseX, mouseY);    
    robot.mousePress(java.awt.event.InputEvent.BUTTON1_MASK);
    robot.mouseRelease(java.awt.event.InputEvent.BUTTON1_MASK);
    robot.mousePress(java.awt.event.InputEvent.BUTTON1_MASK);
    robot.mouseRelease(java.awt.event.InputEvent.BUTTON1_MASK);
    robot.delay(2000);
    
}

    Thank You for the support!!
