angularjs $rootScope $broadcast在一个controller可以接收到

Question

下面这个controller可以收到消息order.controller('loginIn', ['loginSe','$scope',loginIn]);function loginIn(loginSe,$scope) {    var self=this;     this.loginState=0;     $scope.$on('load',function (event,data) {        self.loginState=data.loginState;             self.headPic=localStorage.headPic;     })     this.loginSe=loginSe;     this.floatM=0; }下面这个就不行order.controller('wait', ['$scope', '$interval', '$stateParams', '$location','oFirst', function ($scope, $interval, $stateParams,  $location,oFirst) {    $scope.$on('load',function (event,data) {        console.log('s')  })
