Angular JS Table 格式化

Question

我有一个 AngularJS 应用程序，其中有一个 table，如下图所示，

如您所见，最后一列包含每行的删除和编辑按钮。如何在按下相应的删除按钮时突出显示行？

这是我的代码：https://plnkr.co/edit/ZNzgVO59eWJSVMH7?preview

Answer 1

这可以通过在angular js中使用ng-class来实现

逻辑。

单击删除按钮时，在该行上设置一些标志以指示该行处于活动状态我使用了 isActive class.
然后使用ng-class条件，ng-class="{'highlight': emp.isActive == true}"。
由于您正在使用 JavaScript confirm 方法，因此您必须使用 setTimeout 函数来触发 confirm 对话框。否则更改将在 DOM.
由于您使用了 setTimeout，您必须使用 $scope.$apply() 才能使您的更改反映在 UI。

工作Fiddle。
