这是我的函数:

$rootScope.$emit('setTitle', newVal.full_name);

$rootScope.$on('setTitle', function(event, title) {
    if (scope.item) 
        scope.item.name = title;
    else 
        scope.item = {name: title};
});

首先，亲子范围关系确实很重要。你有两种可能触发事件:

$broadcast——向下分派事件到所有子作用域， $emit——通过作用域层次结构向上分派事件。

我对你的控制器(作用域)关系一无所知，但有几个选项:

If scope of firstCtrl is parent of the secondCtrl scope, your code should work by replacing $emit by $broadcast in firstCtrl: function firstCtrl($scope) { $scope.$broadcast('someEvent', [1,2,3]); } function secondCtrl($scope) { $scope.$on('someEvent', function(event, mass) { console.log(mass); }); } In case there is no parent-child relation between your scopes you can inject $rootScope into the controller and broadcast the event to all child scopes (i.e. also secondCtrl). function firstCtrl($rootScope) { $rootScope.$broadcast('someEvent', [1,2,3]); } Finally, when you need to dispatch the event from child controller to scopes upwards you can use $scope.$emit. If scope of firstCtrl is parent of the secondCtrl scope: function firstCtrl($scope) { $scope.$on('someEvent', function(event, data) { console.log(data); }); } function secondCtrl($scope) { $scope.$emit('someEvent', [1,2,3]); }

你可以从控制器调用一个返回承诺的服务，然后在控制器中使用它。并进一步使用$emit或$broadcast通知其他控制器。 在我的情况下，我必须通过我的服务进行http调用，所以我做了这样的事情:

function ParentController($scope, testService) {
    testService.getList()
        .then(function(data) {
            $scope.list = testService.list;
        })
        .finally(function() {
            $scope.$emit('listFetched');
        })


    function ChildController($scope, testService) {
        $scope.$on('listFetched', function(event, data) {
            // use the data accordingly
        })
    }

我的服务是这样的

    app.service('testService', ['$http', function($http) {

        this.list = [];

        this.getList = function() {
            return $http.get(someUrl)
                .then(function(response) {
                    if (typeof response.data === 'object') {
                        list = response.data.results;

                        return response.data;
                    } else {
                        // invalid response
                        return $q.reject(response.data);
                    }

                }, function(response) {
                    // something went wrong
                    return $q.reject(response.data);
                });

        }

    }])

最简单的方法:

超文本标记语言

  <div ng-app="myApp" ng-controller="myCtrl"> 

        <button ng-click="sendData();"> Send Data </button>

    </div>

JavaScript

    <script>
        var app = angular.module('myApp', []);
        app.controller('myCtrl', function($scope, $rootScope) {
            function sendData($scope) {
                var arrayData = ['sam','rumona','cubby'];
                $rootScope.$emit('someEvent', arrayData);
            }

        });
        app.controller('yourCtrl', function($scope, $rootScope) {
            $rootScope.$on('someEvent', function(event, data) {
                console.log(data); 
            }); 
        });
    </script>

我还会建议第四个选项，作为@zbynour提议的选项的更好替代方案。

使用rootScope美元。$emit而不是$rootScope。不管发送和接收控制器之间的关系。这样，事件就保留在$rootScope的集合中。$$监听器，而$rootScope。将事件传播到所有子作用域，其中大多数子作用域可能不是该事件的监听器。当然，在接收控制器端，你只需使用$rootScope。$on。

对于这个选项，你必须记得销毁控制器的rootScope监听器:

var unbindEventHandler = $rootScope.$on('myEvent', myHandler);
$scope.$on('$destroy', function () {
  unbindEventHandler();
});

这是我的函数:

$rootScope.$emit('setTitle', newVal.full_name);

$rootScope.$on('setTitle', function(event, title) {
    if (scope.item) 
        scope.item.name = title;
    else 
        scope.item = {name: title};
});
