不能从angularJs指令中获得控制器的功能

Question

我试图在内部编辑之后在我的控制器中运行一个函数来更新我的底层数据，但是它不会触发.不明白为什么。我怎么才能检查我是否在正确的范围内？我在用Meanjs

作为测试，我试图在控制器中触发testar()函数。

angular.module('customers').directive('editInPlace', [
function() {
    return {
        restrict: 'E',
        scope: {
            value: '='
        },
        template: '<span ng-click="edit()" ng-bind="value"></span><input ng-model="value"></input>',
        link: function (scope, element, attrs) {
            // Let's get a reference to the input element, as we'll want to reference it.
            var inputElement = angular.element(element.children()[1]);

            // This directive should have a set class so we can style it.
            element.addClass('edit-in-place');

            // Initially, we're not editing.
            scope.editing = false;

            // ng-click handler to activate edit-in-place
            scope.edit = function () {
                scope.editing = true;

                // We control display through a class on the directive itself. See the CSS.
                element.addClass('active');

                // And we must focus the element.
                // `angular.element()` provides a chainable array, like jQuery so to access a native DOM function,
                // we have to reference the first element in the array.
                inputElement[0].focus();
            };

            // When we leave the input, we're done editing.
            inputElement.prop('onblur', function () {
                scope.editing = false;
                element.removeClass('active');
                console.log("trigg");
                scope.$apply("testar()");
            });
        }
    };
}

])；

angular.module('customers').controller('CustomersController', ['$scope', '$stateParams', '$location', 'Authentication', 'Customers',
function($scope, $stateParams, $location, Authentication, Customers ) {
    $scope.authentication = Authentication;

    // Create new Customer
    $scope.create = function() {
        // Create new Customer object
        var customer = new Customers ({
            name: this.name,
            firstName:this.firstName
        });

    $scope.testar = function () {
        console.log("jojjemen från controller");
    }

}

])；

添加到您的范围：

scope
{
  value: '=',
  controllerFunction: '='
}

在您调用的链接函数上：

   scope.controllerFunction();

然后在HTML上，当包含指令时，需要将控制器函数作为属性传递：

<edit-in-place value="something" controller-function="testar">
