如何在angular2中设置动态ID？

How to set dynamic id in angular2?

我试过了

<div class = "CirclePoint" *ngFor="#c of circles" id = "{{ 'Location' + c.id }}"></div>

this.circles = [
        { x: 50 , y: 50 ,id : "oyut1" },
        { x: 100 , y: 100 ,id : "oyut3"  },
        { x: 150 , y: 150 ,id : "oyut2"  }
];

但它不起作用。

推荐答案

<div class = "CirclePoint" *ngFor="let c of circles" 
    [attr.id]="'Location' + c.id">
</div>

<div class = "CirclePoint" *ngFor="let c of circles" 
    attr.id="Location{{c.id}}">
</div>

对于 id 属性这也可能有用（我还没试过）

For the id attribute this might work as well (not tried myself yet)

<div class = "CirclePoint" *ngFor="let c of circles" 
[id]="'Location' + c.id">
</div>
