从控制器调用指令方法 [英] calling a directive method from controller

问题描述

我正在创建一个带有 angular 的指令，并且我正在使用 kendo-window 控件.现在我想根据控制器的要求打开那个剑道窗口.简单来说，我想在单击按钮时从 controller 调用 directive 的方法.

这是我的代码示例

sample.directive('workorderwindow', [initworkorderwindow]);函数 initworkorderwindow() {返回 {链接:函数(范围、元素、属性){},限制:'E'，模板:"<div data-kendo-window='window.control' data-k-options='window.config'> HELLOW RORLD </div>",范围: {},控制器:函数($scope){$scope.window ={控制:空，配置:{ 标题:'你好世界'，可见:假}}$scope.open = 函数 () {$scope.window.control.center().open();}}}}

现在我想从我的控制器调用那个指令 open 方法.

 sample.controller('datacontroller', ['$scope', 'datafac', initcontroller]);函数 initcontroller($scope, datafac) {$scope.onsampleclick = 函数 () {//从这里}

解决方案

直接从控制器调用指令的函数可能是一种不好的做法.你可以做的是创建一个服务，从你的控制器调用它并在你的指令中注入这个服务.使用 $watch 您将能够触发您的指令功能.

Controller 和 Directive 之间的服务

app.factory('myWindowService', function () {返回 {windowIsOpen : 空，打开窗口:函数(){this.windowIsOpen = true;},关闭窗口:函数(){this.windowIsOpen = false;}};

您的指令:

app.directive('workorderwindow', function () {返回 {限制:'E'，模板:<div>test</div>",控制器:函数($scope，myWindowService){$scope.windowService = myWindowService;$scope.$watch("windowService.windowIsOpen", function (display) {如果(显示){console.log("in 指令");//$scope.window.control.center().open();}//你也可以在这里关闭它});}};})

并从您的控制器调用它

app.controller('datacontroller', function ($scope, myWindowService) {$scope.open = 函数 () {myWindowService.openWindow();}//$scope.close = ...});

I am creating a directive with angular and in that i am using kendo-window control. Now i want to open that kendo window on demand from controller. In simple words i want to call a method of directive from controller on button click.

Here is my code sample

sample.directive('workorderwindow', [initworkorderwindow]);
    function initworkorderwindow() {
        return {
            link: function (scope, elements, attrs) {
            },
            restrict: 'E',
            template: "<div data-kendo-window='window.control' data-k-options='window.config'> HELLOW RORLD </div>",
            scope: {

            },
            controller: function ($scope) {
                $scope.window =
                    {
                        control: null,
                        config: { title: 'HELLO WORLD', visible: false }
                    }
                $scope.open = function () {
                    $scope.window.control.center().open();
                }
            }
        }
    }

HTML

<workorderwindow></workorderwindow>

Now i want to call that directive open method from my controller.

 sample.controller('datacontroller', ['$scope', 'datafac', initcontroller]);
        function initcontroller($scope, datafac) {
            $scope.onsampleclick = function () {
//FROM HERE
            }

解决方案

It's probably a bad practice to directly call a function of your directive from a controller. What you can do is create a Service, call it from your controller and injecting this service in your directive. With a $watch you will be able to trigger your directive function.

The service between Controller and Directive

app.factory('myWindowService', function () {
return {
    windowIsOpen : null,
    openWindow: function () {
        this.windowIsOpen = true;
    },
    closeWindow: function () {
        this.windowIsOpen = false;
    }
};

Your directive :

app.directive('workorderwindow', function () {
return {
    restrict: 'E',
    template: "<div>test</div>",
    controller: function ($scope, myWindowService) {
        $scope.windowService = myWindowService;

        $scope.$watch("windowService.windowIsOpen", function (display) {
            if (display) {
                console.log("in directive");
                //$scope.window.control.center().open();
            }
            // You can close it here too
        });
    }
};
})

And to call it from your controller

app.controller('datacontroller', function ($scope, myWindowService) {
  $scope.open = function () {
      myWindowService.openWindow();
  }
  // $scope.close = ...
});
