Is it possible to trigger a keyboard button with JavaScript?

Question

Is it possible to trigger a keyboard button with JavaScript, and to get a input-case depending on the Caps Lock button?

So, if my Caps Lock is on, "IT SHOULD BE UPPERCASED" or "it should be lowercased if it's off".

Answer 1

Trigger an key event:

var ev = jQuery.Event("keypress");
ev.ctrlKey = false;
ev.which = 37;
$("container").trigger(ev);

Hope that helps.
