This article mainly introduces the comprehensive operation method of adding users, changing passwords, sensitive words, and drop-down menus in Angular js. Friends in need can refer to it. I hope it can help everyone.

In the last article, the editor introduced you to the AngularJS fuzzy query function implementation code (filter content drop-down menu, sort, filter sensitive characters, add table information after verification and judgment), today I will introduce to you the Angular js implementation of adding The comprehensive operation methods for users, changing passwords, sensitive words, and drop-down menus are as follows:

Without further ado, I will just post the code for you. The specific code is as follows:
