AngularJS UI Bootstrap 模式无法从范围执行功能 [英] AngularJS UI Bootstrap modal is unable to perform functions from scope

问题描述

在我的 angularjs 应用程序中，我使用 UI Bootstrap 来创建模态.我将范围和自定义控制器传递到模态中，它显示了来自原始范围的数据，但无法执行其任何功能.我有主控制器:

In my angularjs app I use UI Bootstrap for creating modals. I pass scope and custom controller into the modal, it shows my data from original scope but cannot perform any of its function. I have main controller:

myapp.controller('WsCtrl', function WsCtrl($scope, $location, todoStorage, filterFilter, $modal, $log) {

在控制器中我有下一个:

In controller I have next:

$scope.items = ['item1', 'item2', 'item3'];
$scope.open = function () {
    var modalInstance = $modal.open({
        templateUrl: 'partials/users.html',
        scope: $scope,
        controller: ModalInstanceCtrl,
        resolve: {
            items: function () {
                return $scope.items;
            },
            users: function(){
                return $scope.users;
            },
            CurrentDate: function(){
                return $scope.CurrentDate;
            }
        }
    });

    modalInstance.result.then(function (selectedItem) {
        console.log(selectedItem);
    }, function () {
        $log.info('Modal dismissed at: ' + new Date());
    });
};

而且我在控制器之外还有另一个功能:

And also I have another function outside the controller:

var ModalInstanceCtrl = function ($scope, $modalInstance, items) {

    $scope.items = items;
    $scope.users = users;
    $scope.CurrentDate = CurrentDate;
    $scope.selected = {
        item: $scope.items[0]
    };
    $scope.num = 11;

    $scope.ok = function () {
        $modalInstance.close($scope);
    };

    $scope.cancel = function () {
        $modalInstance.dismiss('cancel');
    };
};

当我将作用域传递给 modal 时 - 我可以看到我的所有用户，但我无法添加一个导致我原始作用域中的函数出现问题".

When I pass the scope to modal - I can see all my users, but I can't add one 'cause off problem with functions in my original scope.

推荐答案

您不需要 scope: $scope.resolve 参数负责将变量传递给 ModalInstanceCtrl.但是您必须将这些参数添加到其依赖项中(它们的名称必须与 resolve 中的名称匹配)，因此如果您有:

You don't need scope: $scope. The resolve parameter is responsible for passing variables to ModalInstanceCtrl. But you must add those parameters to its dependencies (their names must match those from resolve), so if you had:

resolve: {
    foo: function(){
        return $scope.something
    }
}

那你一定有

var ModalInstanceCtrl = function ($scope, $modalInstance, foo) {
    $scope.foo = foo;
    // ...
}

哦，函数可以像其他变量一样传递，在resolve中:

Oh, and functions can be passed just like other variables, inside resolve:

resolve: {
    someFunction: function(){
        return $scope.someFunctionFromOriginalScope
    }
}

此外，您可以在 resolve 部分注入任何其他服务并在其中执行其他逻辑:

Additionally, you can inject any other service in the resolve section and perform additional logic inside of it:

resolve: {
    someFunction: function(configService){
        if (configService.isProduction){
            return angular.noop;
        } else {
            return $scope.someFunctionFromOriginalScope;
        }
    }
}
