Create KeyEvent in Javascript

Question

I have the following problem - I'm catching a key event an I need to create a new altered key event(since it seems the keyCode property is read-only) and afterwards handle the newly created KeyEvent. I came across several old posts in StackOverflow where similar situations are handled, but:

I need this to be working under Webkit /there's a solution here in StackOverfow but it is working only in Gecko/
I need to create another KeyEvent, but not TextInputEvent, since the TextInputEvent will only let my specify a string to be inserted, whilst I cannot do that as I use a third party tool that needs to handle this event and I need a keycode.

I tried jQuery#trigger() but it won't work for me. My code is as follows

var event = jQuery.event('keydown');
event.which = 13; //I'm trying to simulate an enter
$('iframe').contents().find('document').find('body').trigger(event); //my content is inside an iframe

(function($){
    $(window).load(function(){

        var e = $.Event("keydown");
        e.which = 13;
        e.keyCode = 13;
        $('iframe').contents().find('html, body').trigger(e);

    });
})(jQuery);

I have not the time to create a test example. Just give it a try. Thanks

nope, for some reason this wont work, the iframe's body is found but the event is not triggered or triggering it leads to nothing. No errors are produced in the log.

I went ahead and used TextInputEvent and document.dispatchEvent(). Seems working.
