AngularJS实现对用户信息的增删改查-蒲公英云

本篇是对表单进行增删改查的操作，用到的是AngularJS实现的，有需要的可以看一下。

实现效果：

实现要求：

搭建页面
显示所有用户信息
根据用户名实现用户查询显示
根据年龄范围下拉菜单实现用户显示
根据用户年龄实现用户显示
实现批量删除功能：选中左侧多选框，点击批量删除，删除选中项，没选中提示用户，点击最上方的多选框，实现全选。
点击添加用户，下方页面显示添加用户界面，填写用户信息，满足条件如下进行添加

a) 用户名非空

b) 两次密码一致

c) 年龄在10到60之间

点击修改密码按钮，下方页面显示修改密码页面（如下），默认把要修改的用户名显示在用户名输入框，并且不能更改用户名，实现密码修改，要求如下

a) 旧密码要跟之前的密码一致

b) 两次输入的密码一致。
