How to properly place js in Bitrix?

Question

JavaScript

Hello.
I want to place a handler for a pair of fields in Bitrix (product property entry form), I can’t figure out where to shove the code. I don’t want to fence in all the files, I’m new to Bitrix.
Need an input control (input format) in a pair of SKU edit fields. both in the admin panel and through the catalog page.
How to do it better?

Answer 1

To do this, it is better to use a component connected to the current theme. In it you include js and styles what you need.
You can take from the /bitrix/components/bitrix/component_name/desired template folder. Here is a description of working with components .
This approach will allow you to make normal fields and their logic for sites on 1C-Bitrix. Usually, validators are written
for forms so that the system does not display errors when checking. But you can not bathe and do the same . PS: I advise you to read Bitrix Site Management courses in your free time.
