Simulate a keystroke so that it is not obsolete?

Question

I am looking for a way to simulate a keystroke on a keyboard (e.g. hints). I looked around and I basically found these two questions:

• Is it possible to programmatically simulate keypress events?
• Simulate a keystroke without jquery

The problem is that they both use the KeyboardEvent.initKeyboardEvent() event, which is deprecated according to MDN . Is there any other way to accomplish the same thing without this deprecated function?

I would like to know this because I am creating a script for YouTube using the Chrome TamperMonkey extension. This script will, when [space] is pressed, call K. K - YouTube / Play / Pause button. I have a [space] listener that works fine with the code below:

 document.addEventListener("keydown", function(e) { if(e.keyCode==32) { e.preventDefault(); } }, false); 

Also I'm really looking for an approach using pure JavaScript.

If you do this using jQuery, you will create your event.

If you want to create an event, you initialize the object and then dispatch the event.

 document.addEventListener("keypress", function(e) { alert(e.which); }); var e = new Event("keypress"); e.which = 65; e.keyCode = 65; document.dispatchEvent(e);
