AngularJS - 通过"&"将函数绑定到隔离范围，而不是在ng单击时触发

Question

我有一个带有控制器的父指令，它在$scope上设置了一个方法。

然后，在子指令中，我尝试通过&要求scope方法。

然而，子指令中的ng-click不会通过父作用域函数触发。我做错了吗?

父指令(其中定义了方法)

app.directive('ParentDirective', [
    '$http',
    function($http) {
        return {
            restrict: 'AE',
            template: '' +
                '<div child-directive ' +
                    'list="list" ' +
                '/>' +
            '',
            controller: function ($scope, $http) {
                $scope.setSelected = function (selector) {
                    console.log('hit!', selector);
                }
                $scope.list = [];
            },
            link: function postLink(scope, element, attrs) {}
        };
    }
]);

子指令(尝试在ng-click上调用父方法，但不工作)

app.directive('childDirective', [
        '$window',
        function($window) {
            return {
                restrict: 'AE',
                scope: {
                    setSelected: '&',
                    list: '=',
                },
                template: '' +
                    '<ul>' +
                        '<li ng-repeat="person in list" ng-click="setSelected(person)">{{person.uri}}</li>' +
                    '</ul>' +
                '',
                link: function postLink(scope, element, attrs) {
                }
            };
        }
    ]);

我传递$scope.setSelected()错误从父到子指令?

EDIT:所以我改变了父模板，像这样分配函数:模板:"+" +",

现在将触发该函数，但参数不会从子指令传递。我怎样才能让子指令传递一个参数到父指令函数?

ParentDirective有打字错误，应该是:ParentDirective

在parentDirective模板中你应该传递函数'list="list" ' + 'set-selected="setSelected(person) "

试试这个:html:

<parent-directive ></parent-directive>

js:

app.directive('parentDirective', [
    '$http',
    function($http) {
        return {
            restrict: 'AE',
            template: '' +
                '<div child-directive ' +
                    'list="list" ' + 'set-selected="setSelected(person)"'+
                '/>' +
            '',
            controller: function ($scope, $http) {
                $scope.setSelected = function (selector) {
                    console.log('hit!', selector);
                }
                $scope.list = [];
            },
            link: function postLink(scope, element, attrs) {}
        };
    }
])
  app.directive('childDirective', [
        '$window',
        function($window) {
            return {
                restrict: 'AE',
                scope: {
                    setSelected: '&',
                    list: '=',
                },
                template: '' +
                    '<ul>' +
                        '<li ng-repeat="person in list" ng-click="setSelected({person:person})">{{person.uri}}</li>' +
                    '</ul>' +
                '',
                link: function postLink(scope, element, attrs) {
                }
            };
        }
    ]);

工作恰好:
