导读: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 }}"/divthis.circles = [ { x: 50,y: 50,id : "oyut1" },{ x: 100,y: 100,id : "oyut3" },{ x: 150,y: 150,id : "oyut2" } ]; 但它不行。
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> (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
