Does submit() function has a callback?

Question

Hi, I have this code, and a file upload form which is submited to a frame:

setMyCookie('name','value_1');
$('.myform').submit();
setMyCookie('name','value_2');

Problem: Webkit browsers seem to update 'MyCookie' with 'value_2' before the form gets submited, or in the exact moment it is being submited, so wrong cookie value is sent with it. I want to change cookie value to 'value_2' immediately after the form is submited so the cookie is ready for another request.

The following code works fine, but I don't think using timeout() is the best solution. Maybe there is another way to solve this problem?

setMyCookie('name','value_1');
$('.myform').submit();
setTimeout(function(){setMyCookie('name',value_2);},100);

Thanks.

Answer 1

Yes, you can. See here.

Answer 2

No. Submitting a form loads an entirely new page, which usually ends the current execution context for the script.

The exception is if you submit the form to a frame, in which case an onload event will fire.

Answer 3

You would have to use AJAX to accomplish that. Otherwise, the form is submitted and the rest of the JavaScript that your function was going to execute is ignore because the page is reloaded.
