$ scope。$ $在$ rootScope之后没有触发。$在角度服务中广播 [英] $scope.$on not triggering after $rootScope.$broadcast in angular service
问题描述
这可能是重复的问题,但我发现这个问题的解决方法在我的情况下不起作用,这就是我发布问题的原因。
This may be the repeated question but the workaround I found for this issue is not working in my case thats why I am posting the question.
我关注服务
appRoot.service('MyService', function($rootScope) {
var Messenger = {
Temp: "",
TempId:"",
tempMethod: function(Id) {
TempId = Id;
$rootScope.$broadcast('FirstCtrlMethod');
}
};
return Messenger ;
});
在第二个控制器中
appRoot.controller('SecondCtrl', function ($scope, $location, MyResource, NotificationService, MyService) {
$scope.invokeFirstCtrl= function() {
var Id = '2';
MyService.tempMethod(Id);
});
第一个控制器:
appRoot.controller('FirstCtrl', function ($scope, $compile, $filter, $modal, $sce, $location, NotificationService, MyService) {
$scope.$on('FirstCtrlMethod', function () {
alert('I am from frist controller');
});
});
问题:行$ rootScope。$ broadcast( 'FirstCtrlMethod');按预期执行,但它不会导致触发事件$ scope。$ on('FirstCtrlMethod',function(){..在第一个控制器。
我在我的应用程序中的许多地方以相同的方式使用了不同的服务,并且它们工作正常,我不明白它为什么不在这里工作。
Problem: The line "$rootScope.$broadcast('FirstCtrlMethod');" is executing as expected but it is not causing to fire event "$scope.$on('FirstCtrlMethod', function () {.." in the first controller. I've used the differenct services in many places in my app in the same way and they are workig fine, I am not understanding why it is not working here.
推荐答案
将评论作为答案......
putting comment as an answer...
我想其他应该接收事件的控制器当你在$播放活动时尚未实现。
I guess the other controller which is supposed to receive the event is not yet instatiated when you are $broadcasting the event.
请尝试实例化其他控制器
Please try instantiating the other controller
