通常,我创建了一个使用$scope
语法的控制器,因此,我可以将当前的$ scope传递给modal指令的隔离范围,如下所示:
$scope.openEditModal = function() {
$scope.modalInstance = $modal.open({
templateUrl: 'views/budgets/mainbudgets/edit',
scope: $scope // Passing a $scope variable
});
$scope.modalInstance.close();
};
但是,我只是将控制器切换为使用this
语法:
var self = this;
// User edit modal
this.openEditModal = function() {
self.modalInstance = $modal.open({
templateUrl: 'views/budgets/mainbudgets/edit',
scope: self; // This doesn't work
});
self.modalInstance.close();
};
那么,如何传递当前this
以用于模态指令的隔离范围?
修改
这是我的控制器的整个代码:
angular.module('sms.budgets').controller('BudgetsMainController', ['$scope', 'Global', '$modal', '$timeout', '$rootScope','Budgets', function($scope, Global, $modal, $timeout, $rootScope,Budgets) {
var self = this;
this.newBudget = {};
this.budgets = [];
function init() {
var data = {};
// Load main budget from DB
Budgets.load('main-budgets').success(function(budgets) {
self.budgets = budgets || [];
});
}
init();
/**
* Create a new main budget
*/
this.create = function() {
var data = {};
data.budget = self.newBudget;
data.dbName = 'Budget';
Budgets.create('budgets', data).success(function() {
self.isSuccess = true;
$timeout(function() {
self.isSuccess = false;
}, 5000);
}).error(function(err) {
self.isError = true;
$timeout(function() {
self.isError = false;
}, 5000);
});
};
this.edit = function() {
self.modalInstance.close();
};
// User edit modal
this.openEditModal = function() {
var newScope = $rootScope.$new();
newScope.modalInstance = self.modalInstance;
newScope.edit = self.edit;
self.modalInstance = $modal.open({
templateUrl: 'views/budgets/mainbudgets/edit',
scope: newScope
});
self.modalInstance.close();
};
this.cancelEditModal = function() {
self.modalInstance.dismiss('cancel');
};
}]);

您不能将此作为范围使用。它们是不同的。由于$ scope是AngularJS的内部变量,因此必须保持原样。
为了表明这一点,我创建了一个Plunkr(打开控制台,看看这个和$ scope之间的差异)
http://plnkr.co/edit/DkWQk4?p=preview
无论如何,在模态控制器上使用不同的范围是一种很好的做法。这里有一个示例,说明如何在主控制器和模态控制器之间进行通信:
来自 MainCtrl :
var modalInstance = $modal.open({
templateUrl: 'views/parts/modalUrlImg.html',
controller: 'ModalUrlCtrl',
resolve: {
url: function () { // pass the url to the modal controller
return $scope.imageUrl;
}
}
});
// when the modal is closed, get the url param
modalInstance.result.then(function (url) {
$scope.courses[i].imageUrl = url;
});
从模态控制:
.controller('ModalUrlCtrl', function($scope, $modalInstance, url) {
$scope.url = url; // get the url from the params
$scope.Save = function () {
$modalInstance.close($scope.url);
};
$scope.Cancel = function () {
$modalInstance.dismiss('cancel');
};
$scope.Clean = function () {
$scope.url = '';
};
});
希望这能帮到你,欢呼。

您可以将控制器保留为语法。实际上,您必须混合两种语法,因为您只能使用它来添加变量和函数,但不能访问其他范围内的东西,例如$ scope。$ on ...
所以,要在你的情况下这样做,只需传递$ scope:
var self = this;
// User edit modal
this.openEditModal = function() {
self.modalInstance = $modal.open({
templateUrl: 'views/budgets/mainbudgets/edit',
scope: $scope;
});
self.modalInstance.close();
};
我已经尝试过更新的plunkr,它现在正在运行:

$ scope!= controller
通过将this
传递给$modal.open()
,您传递的是控制器的引用,而不是范围。请尝试传递$scope
。
