angularjs使用路由跳轉到某個view的時候，如何執行js來修改一個導航菜單某一項為激活狀態，下面是我現在的代碼varmainapp=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='EveryonecomeandseehowgoodIlook!';});
