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>
