This article mainly introduces jquery DataTable to implement front and back dynamic paging. The editor thinks it’s pretty good, so I’d like to share it with you now and give it as a reference. Let’s follow the editor to take a look, I hope it can help everyone.

Organize the documents, search out a jquery DataTable to implement dynamic paging in the front and backends, and organize and streamline it a little for sharing.
