我可以从javascript伪造CE-HTML密钥常量吗？

Question

I would like to fake ie trigger a keycode event which matches a custom keycode defined in the CE-HTML standard for NetTV. Is this possible from the javascript console in chrome / firefox? I tried:

var e = jQuery.Event("keydown");
e.which = 406; // this is the custom keycode value for constant VK_BLUE (blue button on remote control)
$("input").trigger(e);

But it has no effect. I have a feeling this might be restricted.

If its not possible, can I send a code like that from my operating system (OSX) by triggering that keycode event somehow? Or is 406 completely meaningless outside of the NetTV environment?

Answer 1

You should be able to fake an event object like so:

var e = jQuery.Event("keydown", { keyCode: 64 });
$("input").trigger(e);

Answer 2

You could use Applescript to send you keycode:

tell application "yourApplication"
    activate
    tell application "System Events" to key code 406
end tell
