Angular $ broadcast仅在页面刷新后更新 [英] Angular $broadcast only updating after page refresh

问题描述

我在Angular中遇到问题，其中$scope.$broadcast仅在刷新页面一次后才更新监听值:

Hi I have a problem in Angular where $scope.$broadcast is only updating a listening value once the page has been refreshed once:

一个控制器:

$rootScope.$broadcast('myVar', myValue);

监听器:

$scope.$on('myVar', function(event, myValue) {
    console.log(myValue);
    $scope.myValue= myValue;
});

如果我刷新一次页面，它可以工作，但是在初始加载时，侦听器无法正常工作吗? 有什么想法吗?

It works if I refresh the page once, but on initial load the listener is not working? Any ideas?

推荐答案

我已经使用$window.location.reload();解决了这个问题，看来我需要重新加载控制器才能重新启动侦听器.

I have solved the problem, using $window.location.reload(); it appeared that I needed to reload the controller to re-initiate the listener.
