I'm trying to create a website and it's going to be used on Smart TV browsers...
I would like to facilitate user's navigation only using the channel changer button, so my question is:

Is it possible to make a function to detect Channel Up or Channel Down on my website and switch the page?

For example:
If I click on the Channel Up button on the remote control, it goes to page 2.
And if I click the Channel Down button on the remote control, it returns to page 1.

Thanks!

  • FWIW, [Samsung's documentation](https://www.samsungdforum.com/UxGuide/2014/03_input_method.html) suggests that Apps can intercept Channel Up. No word on how its Browser app handles that though. To be honest, this seems like kind of a strange UI you're making. Why not pick a button less surprising? – Lightness Races in Orbit Jan 01 '17 at 22:08
  • well, the browser doesn't send any keypress, only the "space" key when keyboard is detected, so it won't work, even if i choose other button... Thanks. – Ibrahim Orra Jan 02 '17 at 04:03

First thing to check: Is your TV sending the "key" press? You can use simple JS+HTML

<!DOCTYPE html>
<html>
<body>
<script>
document.addEventListener("keydown", function(event) {
  document.getElementById("x").innerHTML=event.which;
});
</script>
<p id="x">The keycode will appear here...</p>
</body>
</html>

Then write down the keycodes. If they aren't showing up, bad luck. Your TV isn't sending the keypress. If they are, using simple "if" you can navigate with Javascript.

  • We are developing an HTML application which we want to run on smart TV/windows box. How do we handle actions on keypress of remote in html. Will the keycodes be different on different remotes ? – samir Aug 09 '18 at 05:01
