DataTable with Ajax Data Source

Post Views: 13

Hello Friends, Hope you are doing well today I am going to share how to use DataTable with Ajax Data Source or you can say how to perform server side processing in DataTable.

Actually I was working on one of my personal project where I was needed this feature and After implementing on my project I thought to share it with you guys. If you don’t know what DataTable is then let me tell you it is nothing but a plug-in for the jQuery Javascript library to work with Html Tables. It comes with various features like searching, sorting, pagination. Let’s start

We will do this coding in three steps:-
