How to run different js code on different pages of the site?

Question

JavaScript

Good afternoon everyone.
Please help me solve this problem.

There is an online store on cms MODX REVO - You need to run js code 1
in the /catalog/ section (this will be a pop-up window with a test), on all categories, subcategories, product cards that have /catalog/ in the url - And js code should be run on the whole site, except for the /catalog/ section . and write like:

if (window.location.pathname.indexOf('/catalog/') >= 0)) {
  return functionone();
}
else {
 return functiontwo();
}

Or assign a variable to functions ..
In general, sorry for the blood from my eyes, and please help, I just started learning js

Answer 1

I don’t know how to sew this inside the JS itself, but you can work out this or that scenario within the framework of a document or template:

выводим если шаблон не равен 12]] 

выводим если ID документа равен 1 или 2 или 3]]

You can include separate scripts in these constructions, which will be executed on the necessary pages.

Answer 2

In MODX revo, you can always have templates that define the output of things like:
Here in them and write this script of yours. It makes no sense to study location. Because with one simple action, /catalog/ is renamed to /product/, but this does not change its essence. But your script will stop working
