问题描述
我是 Angular 2/4 和打字稿的新手.我想获取为电话、电子邮件和地址选择的单选按钮值,并将选定的值传递给打字稿页面.client.info.ts
如何从 html 页面获取在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

解决方案
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"/>
这样做 ngModel
会在你点击单选按钮时根据它的输入值改变
client.info.ts
我建议你遵循 angular 规则来命名这样的组件 client-info.component.ts
在你的组件类中,你只需 delcare radioData
导出类 ClientInfoComponent 实现 OnInit {公共广播数据:任何;<--- 您的无线电数据将在点击时更新ngOnInit() {//用值初始化你的收音机this.radioData = 1;}}
I am new to Angular 2/4 and typescript.. I want to get the radio button values selected for the Phone, email and address and pass the selected values to typescript page. client.info.ts
How do I go about getting the values of the radio button clicked in typescript from html page. I have included my typescript and html code below.
Currently this is not working

解决方案
I'm doing like this in my projects
<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"/>
by doing this ngModel
will be change when u click the radio button according to its input value
client.info.ts
I suggest you to follow angular rules to naming component like this client-info.component.ts
In your component class u simply 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;
}
}
