Angular 2 反应形式（又称模型驱动形式）

此示例使用 Angular 2.0.0 Final Release

注册用 form.component.ts

import { FormGroup,
    FormControl,
    FormBuilder,
    Validators }              from '@angular/forms';

@Component({
    templateUrl: "./registration-form.html"
})
export class ExampleComponent {
    constructor(private _fb: FormBuilder) { }

exampleForm = this._fb.group({
    name: ['DefaultValue', [<any>Validators.required, <any>Validators.minLength(2)]],
    email: ['default@defa.ult', [<any>Validators.required, <any>Validators.minLength(2)]]
})

注册用 form.html

<form [formGroup]="exampleForm" novalidate (ngSubmit)="submit(exampleForm)">
    <label>Name: </label>
    <input type="text" formControlName="name"/>
    <label>Email: </label>
    <input type="email" formControlName="email"/>
    <button type="submit">Submit</button>
</form>
