如何设置角度2中的动态ID？
我努力了
<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" }
];
但它不行。
<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，这可能也是有效的(还没有尝试过)
<div class = "CirclePoint" *ngFor="let c of circles" [id]="'Location' + c.id"> </div>
