javascript - jQuery - prevent default, then continue default

Question

I have a form that, when submitted, I need to do some additional processing before it should submit the form. I can prevent default form submission behavior, then do my additional processing (it's basically calling Google Maps API and adding a few hidden fields to the form) -- and then I need the form to submit.

Is there a way to "prevent default", then some point later "continue default?"

Answer 1

Use jQuery.one()

Attach a handler to an event for the elements. The handler is executed at most once per element per event type

$('form').one('submit', function(e) {
    e.preventDefault();
    // do your things ...

    // and when you done:
    $(this).submit();
});

The use of one prevent also infinite loop because this custom submit event is detatched after the first submit.
