布尔属性的单选按钮 [英] Radio button for boolean property

问题描述

我的对象document中有一个简单的布尔属性valid 并需要将其绑定到无线电输入.

I have a simple boolean property valid in my object document and need to bind it to radio-inputs.

这是我到目前为止所拥有的:

This is what i have so far:

<input type="radio" name="valid" id="validTrue" (click)="document.valid = true" [checked]="document.valid"/>
<input type="radio" name="valid" id="validFalse" (click)="document.valid = false" [checked]="!document.valid"/>

至少可以在单击时设置该属性，但是单选输入不会显示其状态.在浏览器的开发人员控制台中查看时，我发现设置了属性ng-reflect-checked，但似乎对html无线电输入没有影响.

At least setting the property on click works but its state is no displayed by the radio-inputs. Looking in the developer console of my browser i found out that a property ng-reflect-checked is set but it doesnt seem to have impact on the html radio-input.

我做错了什么?
有人可以使用"angular2-boolean-radio-input"代码段吗?

What am i doing wrong?
Does anyone have a working "angular2-boolean-radio-input" snippet?

推荐答案

在新的表单模块中，这可能会做您想要的

In the new forms module this might do what you want

  <input type="radio" name="food" [(ngModel)]="document.valid" [value]="true">
  <input type="radio" name="food" [(ngModel)]="document.valid" [value]="false">

另请参见新表单模块的设计文档
