如何将动态id设置为Angular 2？
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.
<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>
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>
