On
this Minecraft server control panel website (which I didn't write), you can see the amount of players currently logged into the server in the 'Online Players 0/8' section at the top right.
I want to listen to the DOM for changes in that particular 'Online players' text. If the number changes to anything greater than '0 players online', I want to generate an alert('new player!'); and possibly play a sound.
What would be the best approach to do this? What scripting languages? I prefer to work with languages I already know such as Javascript. I read online it should be possible with jQuery.
I tried to inject a script at runtime when the page is loaded (Chrome Developer tools -> Elements section), but that doesn't seem to trigger anything. I tried to put jquery code between the <script></script> tags of the <head></head> tags, but that didn't seem to do anything. Not even a simple alert(); works, so I'm not sure what I'm doing wrong.
Here's what I know:
The control panel seems to be refreshing (polling) the 'status_onlineplayers' td element every second. If you inspect that element, you get this code:
<td id="status_onlineplayers">0 / 8</td>
So, does anyone know how to make this happen? I haven't been successful thus far.
Thanks.
