How do you add Javascript to the Control Panel?

An extension, hooking onto the cp_js_end hook:

http://ellislab.com/expressionengine/user-guide/development/extension_hooks/cp/javascript/index.html

Hmmm,

Took a look at the page but don’t really know what to do with it :-(

If say I had a javascript in a folder on the server called my_script.js then how do I use that hook to attach the javascript? Also if creating this as an extension could I place the script in the same third_party folder as my extension?

Sorry for what is possibly a very dumb question but taking a look at that page didn’t give me much information. Please don’t get me wrong, I’m not blaming you 😉 rather the documentation.

No worries, I’ve mostly figured out by trial and error and / or looking at other developers code.

Basically in the hook function you output the js, so this:

public function on_cp_js_end($data)
{
$html = 'alert("hello!");';
return $html;
}

.. would produce an alert on each and every page.

You can put js code in /themes/third_party/<your_addon>/js/blabla.js and load it in some way I guess.

My best recommendation is to check out the source of some of the addons over on devot-ee and see how they used this hook:

Yep that’s exactly what I’m trying to do.

Doing that now actually 😉

Thanks for the help on this.
