Using php page informations in javascript

Any documentation I could read to try to understand that better?

There are different topics in my post:

• There’s Kirby’s attr() function that formats and escapes HTML attributes for elements
• There’s jQuery’s this in the hover handler, that refers to the event “target” that triggered the current jQuery event.
• There’s jQuery’s data() function that reads and returns from attributes whose name begin with data-

And there’s the general concept about “when what is executed where and by whom”. I wouldn’t know a specific authoritative source online for that.
Maybe we can help you better with more specific questions.
