我想在另一个控制器中共享一个控制器的$ scope函数,在本例中是一个AngularUI对话框。
特别是在下面的例子中,我希望$ scope.scopeVar可以在PopupCtrl中使用。
Resolve code based on mlarcher's comment here
main.js
angular.module('MyApp', ['ui.bootstrap']);
var MainCtrl = ['$scope', '$dialog', '$rootScope', function($scope, $dialog, $rootScope) {
$scope.myTestVar = "hello";
$scope.myOpts = {
backdrop: true,
keyboard: true,
backdropClick: true,
resolve: { MainCtrl: function() { return MainCtrl; }},
templateUrl: 'myPopup.html',
controller: 'PopupCtrl'
};
$scope.scopeVar = 'scope var string that should appear in both index.html and myPopup.html.';
$rootScope.rootScopeVar = "rootScope var string that should appear in both index.html and myPopup.html.";
$scope.openDialog = function() {
var d = $dialog.dialog($scope.myOpts);
d.open().then(function() {
$scope.scopeVar = 'scope var string should be changed after closing the popup the first time.';
$rootScope.rootScopeVar = 'rootScope var string should be changed after closing the popup the first time.';
});
};
}];
var PopupCtrl = ['$scope', 'dialog', 'MainCtrl', function ($scope, dialog, MainCtrl) {
var key;
for (key in MainCtrl) {
$scope[key] = MainCtrl[key];
}
$scope.close = function(){
dialog.close();
}
}];
的index.html

<body ng-controller="MainCtrl">

您有两种选择:
您可以使用附加到rootScope
的控制器上应该可用的scope属性。所以在你的情况下,它看起来像:
$rootScope.scopeVar = "Data that will be available across controllers";
但是,建议不要使用此功能 - 阅读Common Pitfalls
Services。只要您拥有要重复使用的功能或数据,您最好使用服务。
在您的情况下,您可以创建一个存储数据的服务,允许对其进行更改并将数据传递给任何需要它的人。 This回答详细描述了它。
