Question

The controller action is called after the completedCallback not after $(this).submit().
See the code below.
How can i trigger the action before raising the completed callback without using ajax?

controller:

public ActionResult MyFunction(FormCollection data){
//this should trigger before calling the CompletedEvent
}

javascript

var flag = false;

$(form).submit(function(){

        if(!flag){

        //raise start event
        startedCallback.call();

        flag = true;
        $(this).submit();

       //raise completed event
        completedCallback.call();

}

});

If you do not want to use ajax, you cannot reliably call something after the submit – the form’s processing is done. You must use ajax if you want a response.

If you want to call your function BEFORE your form submit – again.. you MUST use some form of ajax.

If you really need control of events like this – you need ajax or iframe hacks. Sorry : )
