angularjs使用路由跳转到某个view的时候,如何执行js来修改一个导航菜单某一项为激活状态,下面是我现在的代码

<script type="text/javascript"> var mainapp = angular.module('mainapp', ['ngRoute']); mainapp.config(function(${routeProvider}) { ${routeProvider} .when('/', { templateUrl : 'marry.php?cid=123&view=home', controller : 'mainController' }) .when('/home', { templateUrl : 'marry.php?cid=123&view=home', controller : 'mainController' }) .when('/process', { templateUrl : 'marry.php?cid=123&view=process', controller : 'mainController' }) .when('/message', { templateUrl : 'marry.php?cid=123&view=message', controller : 'mainController' }); }); mainapp.controller('mainController', function(${scope}) { ${scope}.message = 'Everyone come and see how good I look!'; }); </script>

    大概代码:

    html<body ng-app="app">
        <ul>
            <li><a href="#/" ng-class="{active:path=='/'}">index</a></li>
            <li><a href="#/a" ng-class="{active:path=='/a'}">a</a></li>
            <li><a href="#/b" ng-class="{active:path=='/b'}">b</a></li>
        </ul>
        <p ng-controller="main">
            <p ng-view></p>
        </p>
        <script type="text/javascript">
        var app = angular.module('app', ['ngRoute']);
    
        app.config(['$routeProvider', function($routeProvider) {
    
            $routeProvider
                .when('/', {
                    template: '/index',
                    controller: 'test'
                })
                .when('/a', {
                    template: '/a',
                    controller: 'test'
                })
                .when('/b', {
                    template: '/b',
                    controller: 'test'
                })
                .otherwise({
                    redirectTo: '/'
                });
    
        }]);
    
        app.run(['$rootScope', '$location', function($rootScope, $location) {
    
            $rootScope.$on('$routeChangeSuccess', function(newV) {
                $rootScope.path = $location.path()
            });
    
        }]);
    
        app.controller('main', ['$scope', function($scope){
    
        }]);
    
        app.controller('test', function() {});
    
    
        </script>
    </body>

    预先在每个菜单项上放好激活状态的效果,但是不显示;

    然后通过传特定的值到前台页面来让特定的激活状态显示;

    比如

    <span class="highlight" ng-show="tab == 1"></span>
    <span class="highlight" ng-show="tab == 2"></span>
    <span class="highlight" ng-show="tab == 3"></span>
    <span class="highlight" ng-show="tab == 4"></span>
    

    你在controller里传相应的tab值就行了

    $scope.tab = 1 // 显示第一个为激活状态
    

    或者用这个方法

    <p ng-class='{active:isActive'>
    
    .active{
        ...
    }
    

    angular controller中 控制isActive的值true/false

    <script type="text/javascript"> var mainapp = angular.module('mainapp', ['ngRoute']); mainapp.config(function(${routeProvider}) { ${routeProvider} .when('/', { templateUrl : 'marry.php?cid=123&view=home', controller : 'mainController' }) .when('/home', { templateUrl : 'marry.php?cid=123&view=home', controller : 'mainController' }) .when('/process', { templateUrl : 'marry.php?cid=123&view=process', controller : 'mainController' }) .when('/message', { templateUrl : 'marry.php?cid=123&view=message', controller : 'mainController' }); }); mainapp.controller('mainController', function(${scope}) { ${scope}.message = 'Everyone come and see how good I look!'; }); </script> <ul class="ul_nav"> <li ng-class="{active:path=='#/invitation'}"><a href="#/invitation" class="nav_01"></a></li> <li ng-class="{active:path=='#/map'}"><a href="#/map" class="nav_02"></a></li> </ul>

    你好,我angularjs不太熟,我们项目只用了angularjs的路由功能,上面是我的代码,能帮我基于上面代码直接改好吗
