在Angular 2中打破NgFor循环

问题描述

我正在尝试在模板内使用*ngFor迭代数组，并使用* ngIf搜索基于键的元素.现在，当条件与键匹配时，我想破坏*ngFor.我想知道angular2中是否有任何选项可以根据条件中断ngFor循环.

I am trying to iterate array using *ngFor inside the template and searching for an element based on the key, using *ngIf. Now when the condition is matched with the key I want to break the *ngFor. I wondered if there any option in angular2 to break the ngFor loop based on condition.

推荐答案

没有任何选择可以破坏ngFor.您可以使用自定义管道，该管道在满足条件的元素之后不返回值.

There is no option to break ngFor. You can use a custom pipe that doesn't return values after the element where the condition is met.
