下面是我的代码,我需要将默认值传递给单选按钮
<div class="ui-g-12">
<p-radioButton name="group1" value="Option 1" label="Option 1" [(ngModel)]="val1" inputId="opt1"></p-radioButton>
</div>
<div class="ui-g-12">
<p-radioButton name="group1" value="Option 2" label="Option 2" [(ngModel)]="val1" inputId="opt2"></p-radioButton>
</div>
<div class="ui-g-12">
<p-radioButton name="group1" value="Option 3" label="Option 3" [(ngModel)]="val1" inputId="opt3"></p-radioButton>
</div>
任何人都可以解释如何在表单加载时将默认值设置为单选按钮

首先将您的表单构建方式更改为ReactiveForms
方式:
<form [formGroup]="myForm">
<div class="ui-g-12">
<p-radioButton name="group1" value="Option 1" label="Option 1" formControlName="myRadio" inputId="opt1"></p-radioButton>
</div>
<div class="ui-g-12">
<p-radioButton name="group1" value="Option 2" label="Option 2" formControlName="myRadio" inputId="opt2"></p-radioButton>
</div>
<div class="ui-g-12">
<p-radioButton name="group1" value="Option 3" label="Option 3" formControlName="myRadio" inputId="opt3"></p-radioButton>
</div>
</form>
在组件中,在初始化时设置默认值:
import { Component } from '@angular/core';
import { FormBuilder } from '@angular/forms';
@Component({
selector: 'my-app',
templateUrl: './app.component.html',
styleUrls: [ './app.component.css' ]
})
export class AppComponent {
name = 'Angular 5';
myForm;
constructor(private fb: FormBuilder) {
this.myForm = this.fb.group({
myRadio: ['Option 1', []] // This set default value
})
}
}

除了@Ruben 之外,对于 Primeng 中的布尔类型,您可以在 p-radioButton 中使用 [value] = true。
