您可以通过使用角度事件 $broadcast 或 $emit 来实现这一点.

You could achieve this by using angular events $broadcast or $emit.

在您的情况下 $broadcast 会有所帮助，您需要在 $rootscope 中广播您的事件，该事件可以被具有相同事件名称的 $on 的所有子作用域监听.

In your case $broadcast would be helpful, You need to broadcast your event in $rootscope that can be listen by all the child scopes which has $on with same event name.

代码

.service('SocketService', function($http, $rootScope, $q) {
    this.connect = function() {
        var socket = io();
        socket.on('connect', function() {
            // Call a function named 'someFunction' in controller 'ChatController'
            $rootScope.$broadcast('eventFired', {
                data: 'something'
            });
        });
    }
});


.controller('ChatController', function('SocketService', $scope) {
    $scope.someFunction = function() {
        // Some Code Here
    }
    $scope.$on('eventFired', function(event, data) {
        $scope.someFunction();
    })
});

希望能帮到你，谢谢.
