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;
}
}
回答2:
either use template driven form and [(ng-model)] and to get "value" of the check Box or use Reactive form and use form-control name property to get value of the input assigned to the model.
回答3:
It is recommended to use the FormsModule or Reactive Forms for dealing with form inputs
FormsModule Approach
add this to your app.module.ts
import { FormsModule } from '@angular/forms';
@NgModule({
imports: [ BrowserModule, FormsModule ], // import forms module
declarations: [ AppComponent ],
bootstrap: [ AppComponent ]
})
then inside your component.html
<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>
inside your component.ts create a model for the client object
ngOnInit() {
this.client = {
workPhone: '',
homePhone: ''
};
}
you can use the values from the object anywhere inside the component by referencing the required properties. For eg, if you want to access workPhone use this.client.workPhone.
