Angular2-对象作为无线电输入值

Is it possible to bind a JSON object to a radio input in Angular2?

是否可以将JSON对象绑定到Angular2中的无线电输入？

I have a JSON object named object and I tried

我有一个名为object的JSON对象，我试过了

<input type="radio" [(ngModel)]="selectedObject" [ngValue]="object">

but it gives ngValue is not a known property of input error. I also tried

但它给出了ngValue不是输入错误的已知属性。我也试过了

<input type="radio" [(ngModel)]="selectedObject" value="{{object}}">

But then selectedObject becomes [object Object].

但是后来selectedObject变成了[object Object]。

Thanks to this post, we have an answer:
Use [value]

感谢这篇文章，我们有一个答案：使用[值]

<label *ngFor="let item of items">
    <input type="radio" formControlName="options" [value]="item">
    {{item}}
</label>
