jQuery 按键事件没有发生？

Question

I want to build a small script which triggers the jump move in a Windows fangame. In the game, the jump key is "Z" (KeyCode 90 in my case). So I built this script:

var press = jQuery.Event("keypress");
press.ctrlKey = false;
press.which = 90;
setInterval(function() { $("whatever").trigger(press) }, 2000 );

But when I execute it, nothing happens (I tested it with Firefox). I added console.log("Done") to the function just to see if it works, and it did. I also tried using a textbox seeing if it would maybe write the letters there, but it didn't as well. It's like the event gets ignored by JS.

Can I do something like that in the Browser? Or is it impossible to do so?

Thanks in advance
