Question

Access to "media keys" from within a browser tab

Answer 1

A:

Here's a list of key codes from Microsoft; they include keys such as "VK_VOLUME_MUTE". The key code for VK_VOLUME_MUTE is listed as 0xAD. 0xAD is decimal is 173.

And sure enough, when I load the following and hit the mute button on my keyboard, the key code reported is 173. So they do work like any other key; it wouldn't surprise me, though, if the key codes are Windows-specific. It may take some experimenting.

<html>
<body>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"&gt;&lt;/script&gt;
<script>
$(document).ready(function() {
    $(document).keydown(function(ev){
       alert(ev.keyCode);
    });
});
</script>

</body>
</html>

I have no such luck on Chrome/Linux though...

Ah; I tried it on Chrome/Windows. Yeah, like I said, it's probably OS-specific. Do you get no keydown event firing on Linux, or are you getting a different keycode?

no event at all.

Do the keys work otherwise -- I mean, do they actually change the volume, etc.? If so, you may be out of luck; if there's no event, there's no event. But if not, perhaps you're missing a driver?
