Question

I want to save an unload event to execute it later on. For example:

// on unload do nothing but safe the event
jQuery(window).unload(function() {
            // TODO safe the unload event here somehow
            // unloadEvent = this;
            return false;
});

Later, another piece of code should be able to perform the previously saved event, for example like this:

function finallyUnload() {
        // TODO
        // unloadEvent.perform();
}

Is there any way to do this?

Update

My browser window is communicating with a Java Selenium application and needs to wait until it received the information about the unload event and how it happened. When that’s the case, the unload event can be executed.

I understood that unload events cannot be delayed or stopped, so i got another idea. What about intercepting all clicks on links with href and buttons, also submissions of forms. Then i manually set window.location to the desired URL or submit the form. Could that work?

Answer 1

I found a workaround. I intercept all click and submit events and save them for later use after my application pulled the needed event data.

But it does not work in all cases: Intercept JavaScript unload events
