Prevent duplicate entries in a SharePoint list using Jquery

Hello,

I have to prevent duplicate values based on two columns. I've tried the code referenced here: https://www.codeproject.com/Tips/1205585/Unique-Entries-Based-on-Multiple-Columns-in-Sharep. However, it is not working. I'm using SharePoint Server 2016 on premise.

I'm aware there's a built in function (enforce unique values). However, this does not work with multiple columns.

Is there a way to prevent duplicate entries in SharePoint?
