Angular2组件开发—表单输入（五）

NgFormModel - 绑定已有控件组

NgFormModel指令类似于NgControlGroup指令，都是为控件提供容器。但区别在于，NgFormModel指令将已有的控件组绑定到DOM对象上：

 1 @View({
 2     template : `
 3         <!--绑定控件组与控件对象-->
 4         <div [ng-form-model]="controls">
 5             <input type="text" ng-control="name">
 6             <input type="text" ng-control="age">
 7         </div>`
 8 })
 9 class EzComp{
10     constructor(){
11         //创建控件组及控件对象
12         this.controls = new ControlGroup({
13             name :new Control("Jason"),
14             age : new Control("45")
15         });
16     }
17 }

NgFormModel指令可以包含NgControlGroup指令，以便将不同性质的输入分组。

例如：

 1 <!doctype html>
 2 <html>
 3 <head>
 4     <meta charset="utf-8">
 5     <title>NgFor</title>
 6     <script type="text/javascript" src="lib/system@0.16.11.js"></script>
 7     <script type="text/javascript" src="lib/angular2.dev.js"></script>
 8     <script type="text/javascript" src="lib/system.config.js"></script>
 9 </head>
10 <body>
11     <ez-app></ez-app>
12     <script type="module">
13         import {Inject,Component,View,bootstrap} from "angular2/angular2";
14         import {Control,ControlGroup,formDirectives} from "angular2/forms";
15         
16         @Component({selector:"ez-app"})
17         @View({
18             directives:[formDirectives],
19             template:`
20                 <div [ng-form-model]="controls">
21                     <ul>
22                         <li>姓名：<input type="text" ng-control="name"></li>
23                         <li>地址：<input type="text" ng-control="address"></li>

25                     </ul>
26                 </div>
27                 <div [ng-form-model]="controls1">
28                     <ul>

33                 </div>
34                 <pre>{{dump()}}</pre>
35             `,
36             styles:[`
37                 div{background:#e1f5fe;}
38                 ul{list-style:none;padding:10px;margin:0px;}
39                 li{line-height:30px;}
40             `]
41         })
42         class EzApp{
43             constructor(){
44                 this.controls = new ControlGroup({
45                     name : new Control("Jason"),
46                     address : new Control("London U.K."),
47                     telephone : new Control("114")
48                 });
49                 this.controls1 = new ControlGroup({
50                     name1 : new Control("Jason1"),
51                     address1 : new Control("London U.K.1"),
52                     telephone1 : new Control("1141")
53                 });
54             }
55             dump(){
56             var ddd= 
57             {
58             a: this.controls.value,
59             b: this.controls1.value
60             }
61                 return JSON.stringify(ddd,null,"\t");
62             }
63         }        
64         bootstrap(EzApp);
65     </script>
66 </body>
67 </html>
