Detailed explanation of inline editing examples of dataGrid in EasyUI

This article mainly introduces the implementation code of inline editing of dataGrid in EasyUI. It is very good and has reference value. Friends who need it can refer to it. I hope it can help everyone.

This js code was written by someone else, and it may not be the best, but I personally think it would be particularly good if it can help others solve functional problems first. I modified it slightly and used it in my own project. I will post it here to share it. The TinkPHP used in the backend is relatively simple to check for additions, deletions and modifications, so I won’t post it here. I won’t post the front desk renderings because I’m lazy.
