标签:struct   html   ica   component   模型驱动   react   ali   btn   ext   

1:安装模块

npm install ng2-validation --save

2:配置app.module.ts

import { FormsModule, <font color="Red">ReactiveFormsModule</font> } from @angular/forms;
import {<font color="Red">CustomFormsModule</font>} from "ng2-validation";
...
imports: [
    FormsModule,
    <font color="Red">CustomFormsModule,</font>
    <font color="Red">ReactiveFormsModule</font>
  ],

3:表单验证有两种方式 <1> 模板驱动       <2>模型驱动

接下来我们看下 模板驱动  只有一个步骤 <1>  配置模版文件     ts文件不需要做什么
