Is there an “after submit” jQuery option?

Question

I have a form that uploads a file and targets an iframe on the page. When the user clicks submit, I want the file contents to \"clear\" out.

I tried this

<

Lonesomeday's solution worked for me but for Google Chrome I found it would still submit empty form data unless I added a timeout like this:

$('#imageaddform').submit(function(e) {
    e.preventDefault(); // don't submit multiple times
    this.submit(); // use the native submit method of the form element

    setTimeout(function(){ // Delay for Chrome
        $('#imagefile').val(''); // blank the input
    }, 100);
});
