我尝试使用两种解决方案从子控制器更新我的父作用域,但我无法使其工作。 apply()
没有工作
HTML:
<div ng-controller="ControllerA">
<div ng-show="tab_selected == 1">Content1</div>
<div ng-show="tab_selected == 2">Content2</div>
<div ng-controller="ControllerB">
<span ng-click="updateScope()"></span>
</div>
</div>
JS:
app.controller('ControllerA', ['$scope',
function ($scope) {
$scope.tab_selected = 1;
}]);
app.controller('ControllerB', ['$scope',
function ($scope) {
$scope.updateScope = function(){
$scope.tab_selected = 2;
// $scope.apply(function(){ $scope.tab_selected = 2; });
}
}]);

控制器具有单独的范围,但有几种通信方式

您无法更新父对象中的原始属性,只能更新对象属性。所以你需要使用:
$scope.someObject= {};
$scope.someObject.tab_selected= 2;
