Angular 2/4 如何使用 Angular typescript pass/capture 单选按钮值

Question

我是 Angular 2/4 和 typescript 的新手。我想获取为 Phone、电子邮件和地址选择的单选按钮值，并将所选值传递到 typescript 页面。 client.info.ts

如何从 html 页面获取打字稿中单击的单选按钮的值。我在下面包含了我的打字稿和 html 代码。目前这不起作用

有人可以帮忙吗

这是我的代码

Answer 1

要么使用模板驱动表单和 [(ng-model)] 并获取 "value" 复选框，要么使用 Reactive 表单并使用表单控件名称属性获取值分配给模型的输入。

Answer 2

我在我的项目中就是这样做的

<input type="radio"  name="address" [(ngModel)]="radioData" [value]="a.workPhone"/>
<input type="radio"  name="address" [(ngModel)]="radioData" [value]="a.workPhone"/>
<input type="radio"  name="address" [(ngModel)]="radioData" [value]="a.workPhone"/>
<input type="radio"  name="address" [(ngModel)]="radioData" [value]="a.workPhone"/>

通过这样做 ngModel 将根据其输入值单击单选按钮时更改

client.info.ts 我建议您遵循 angular 规则来命名组件，例如 client-info.component.ts

在你的组件中 class 你只是 delcare radioData

export class ClientInfoComponent implements OnInit {
    public radioData: any; <--- your radio data will be updated when on click

    ngOnInit() {
      // initialize your radio with value
       this.radioData = 1;
    }
}

Answer 3

建议使用FormsModule或响应式表单处理表单输入

FormsModule方法

将此添加到您的 app.module.ts

import { FormsModule } from '@angular/forms';

@NgModule({
  imports:      [ BrowserModule, FormsModule ], // import forms module
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})

然后在你的component.html

里面

<div>
  <input type="radio" name="phone" [(ngModel)]="client.homePhone" [value]="client.homePhone"> 
  {{client.homePhone}}
</div>

<div>
  <input type="radio" name="phone" [(ngModel)]="client.workPhone" [value]="client.workPhone"> 
  {{client.workPhone}}
</div>

在您的 component.ts 中为 client 对象创建一个模型

ngOnInit() {
  this.client = {
    workPhone: '',
    homePhone: ''
  };
}

您可以通过引用所需的属性在组件内的任何位置使用对象的值。例如，如果您想访问 workPhone，请使用 this.client.workPhone.
