我有一个简单的模板驱动形式,如下所示:
HTML:
<div class="container">
<h1>Hero Form</h1>
<form (ngSubmit)="onSubmit()" #heroForm="ngForm">
<div class="form-group">
<label for="name">Name</label>
<input type="text" class="form-control" id="name" [(ngModel)]="model.name" name="name" #name="ngModel">
</div>
<div class="form-group">
<label for="alterEgo">Alter Ego</label>
<input type="text" class="form-control" id="alterEgo" [(ngModel)]="model.alterEgo" name="alterEgo">
</div>
<div class="form-group">
<label for="power">Hero Power</label>
<select class="form-control" id="power" [(ngModel)]="model.power" name="power">
<option *ngFor="let pow of powers" [value]="pow">{{pow}}</option>
</select>
</div>
<button type="submit" class="btn btn-success" [disabled]="!heroForm.form.valid">Submit</button>
</form>
</div>
组件:
import { Component, OnInit } from '@angular/core';
import { Hero } from './hero';
@Component({
selector: 'at-hero',
templateUrl: './hero.component.html',
styleUrls: ['./hero.component.scss']
})
export class HeroComponent implements OnInit {
constructor() {
//
}
ngOnInit() {
//
}
powers = ['Really Smart', 'Super Flexible', 'Super Hot', 'Weather Changer'];
model = new Hero(18, 'Dr IQ', this.powers[0], 'Chuck Overstreet');
submitted = false;
onSubmit() { this.submitted = true; }
newHero() {
this.model = new Hero(42, '', '');
}
}
我怎么能:
答案 0 :(得分:3)
您可以使用array(
key => value,
key2 => value2,
key3 => value3,
...
)
form
加价
ViewChild
<强>组件强>
<form (ngSubmit)="onSubmit()" #heroForm="ngForm">
...
</form>
我建议您也查看Reactive Forms。如果您想在打字稿中使用ViewChild('heroForm') public heroForm: NgForm;
而不是在标记中使用
