IE jQuery form trigger click manually, access is denied

Question

I have a form to upload a image with jQuery form. everting is ok, but when I want trigger file input type click after select a file, in IE ONLY returns this error: access is denied

$('#imageform #photoimg').trigger('click'); or setTimeout(function(){$('#imageform #photoimg').trigger('click')},1000);
$('#photoimg').live('change',function()
{
    //$("#preview").html('');
    //$("#preview").html('<img src="loader.gif" alt="Uploading...."/>');
    $("#imageform").ajaxForm(
        success: function(out) {
            var imageur = out;
            // do tiny work with out;
        }
    }).submit();
});

Where is the problem and how I can resolve it?

Answer 1

By default IE does not let you trigger file element change.

If you want you this feature, can use ajaxuploader or fileuploader:

var uploader = new qq.FileUploader({
    // pass the dom node (ex. $(selector)[0] for jQuery users)
    element: document.getElementById('file-uploader'),
    // path to server-side upload script
    action: '/server/upload'
});

I commented these lines in j query.form.js then every thing works fine for me. Don't ask me the reason even i don't have the solution for that but it works for sure.

            if (io.contentWindow.document.execCommand) {
              try { // #214
                   io.contentWindow.document.execCommand('Stop');
             } catch(ignore) {}
          }
