Stop async execution of code js

Question

After login I have function which gets control.

function formLoginSubmit() {
    if (typeof window.formLoginSubmit_custom != 'undefined') {
        window.formLoginSubmit_custom();
    }
    location.href = '/';
}

And in function formLoginSubmit_custom() I have to do some operations with opening Iframes. The problem is that:

I can't modify formLoginSubmit (don't ask it's just a task I have to do)
Before I've done all operations with my iframes document starts redirecting because of this: location.href = '/';

So how can I stop executing code asyncronously And let my formLoginSubmit_custom() function finish all the operations before changing location.href

What are my options?

If you can't modify `formLoginSubmit_custom` and it is performing async operation, you are in trouble... The only thing you can do is schedule the location change with setTimeout and hope formLoginSubmit_custom has complete. Otherwise, change `formLoginSubmit_custom` to accept a callback and to call it when async operation complete. In the callback body, you'll change the location — Andrea Parodi, Feb 01 '14 at 14:30

Not possible. You would need to change formLoginSubmit to achieve that.

You could drop a cookie "do some work", and when page is reloaded, if you can execute some code - if you find a "do some work" cookie - you could execute that custom() logic in there. But that might not be useful for you depending on what you're trying to achieve.
