angularjs - 根据 Angular 的路线变化添加或删除类

Question

我有 3 条路线，包含 3 个表格我试图根据 Angular 中的当前路线在当前选项卡上设置引导事件类。我使用了 Angular 路线模块。我怎样才能做到这一点。我附上了js代码，请检查并帮忙

            angular.module('bankAppOnline',     ['ngSanitize','ngRoute','ngAnimate','ngQuantum'])
                .config(['$routeProvider',

这可以使用 ng-class 来实现。只需在 Controller 中使用 $location 即可。这个例子非常简单。这里，当 $location.path() 等于 '/' 时，我们向 div 添加一个事件类。

然后我们在 View 中设置一个条件 ng-class 以添加事件类。

查看

<div ng-class="{active: location === '/'}">
  <p>The parent DIV will have active class added when location path equals '/'</p>
</div>

Controller

.controller('MainCtrl', function ($scope, $rootScope, $location) {
    $scope.location = $location.path();
    $rootScope.$on('$routeChangeSuccess', function() {
        $scope.location = $location.path();
    });
});
