Kendo Grid:在 Angular 中获取小部件实例 [英] Kendo Grid: Getting widget instance in Angular

问题描述

我试图在我的 Angular Controller 中获取 Kendo 网格的一个实例，所以我可以尝试连接到一些事件(和调用方法)我知道这可能不是最佳实践(并且可能应该使用自定义指令)，但根据文档，我们应该能够使用...

<input kendo-datepicker="datePicker" k-on-change="onChange()">
<脚本>angular.module("app", [ "kendo.directives" ]).controller("MyCtrl",功能($范围){$scope.onChange = function() {警报($scope.datePicker.value())；};

});

所以，我试图对网格做同样的事情.我有以下标记...

<div kendo-grid='grid' k-options="vm.gridOptions"></div>

然后在控制器js文件中..

 角度.module("mygrid").controller("Grid", ['$scope', Grid]);功能网格($范围){var gridInstance = $scope.grid;...

可以在这里看到

然而，gridInstance 始终是未定义的.有谁知道我是否应该能够对网格执行此操作，如果可以，为什么上述内容总是返回 undefined?

在此先感谢您的帮助

解决方案

两个问题:

1. 如果您使用controller as"语法，则需要为要访问的内容添加前缀(在您的情况下，您需要 kendo-grid="vm.grid" 而不是 剑道网格=网格"
2. 当您的控制器实例化时，Kendo UI 小部件尚不存在(类似问题此处)，因此您需要使用全局 Kendo UI 事件等待它

所以你的 Html 变成了:

<div data-ng-controller="Grid as vm"><div kendo-grid="vm.grid" k-options="vm.options"></div><div>{{vm.msg}}</div>

您的应用:

(函数(){angular.module("app", ["kendo.directives"]).controller("Grid", ["$scope", Grid]);功能网格($范围){var vm = 这个；var gridData = [{col1:'数据1'，col2:'数据2'}, {col1:'数据1'，col2:'数据2'}];vm.options = {数据源:gridData，可真实};$scope.$on("kendoRendered", function (event) {var gridInstance = vm.grid;控制台日志(虚拟机)；vm.msg = gridInstance === 未定义?未定义":已定义"；});}})();

(更新演示)

I was trying to get an instance of the Kendo grid within my Angular Controller, so I can try and hook up to some events (and call methods) I know this is probably not best practice (and should probably use a custom directive), but according to the documentation, we should be able to use...

<div ng-app="app" ng-controller="MyCtrl">
<input kendo-datepicker="datePicker" k-on-change="onChange()">
</div>
<script>
 angular.module("app", [ "kendo.directives" ]).controller("MyCtrl",
   function($scope) {
 $scope.onChange = function() {
 alert($scope.datePicker.value());
};

});

So, I was trying to do the same with the grid. I have the following markup...

<div ng-controller="Grid">
  <div kendo-grid='grid' k-options="vm.gridOptions"></div>  
</div>

and then in the controller js file..

  angular
    .module("mygrid")
    .controller("Grid", ['$scope', Grid]);

    function Grid($scope) {             
      var gridInstance = $scope.grid;
      ...

as can be seen here

However, gridInstance is always undefined. Does anyone know if I shoud be able to do this with the grid, and if so why the above always returns undefined?

Thanks in advance for any help

解决方案

Two issues:

1. If you use the "controller as" syntax, you need to prefix things you want to access (in your case, you need kendo-grid="vm.grid" instead of kendo-grid="grid"
2. When your controller is instantiated, the Kendo UI widget doesn't exist yet (similar question here), so you need to wait on it using a global Kendo UI event

So your Html becomes:

<div data-ng-app="app">
    <div data-ng-controller="Grid as vm">
        <div kendo-grid="vm.grid" k-options="vm.options"></div>
        <div>{{vm.msg}}</div>
    </div>
</div>

Your app:

(function () {
    angular.module("app", ["kendo.directives"])
        .controller("Grid", ["$scope", Grid]);

    function Grid($scope) {
        var vm = this;

        var gridData = [{
            col1: 'data1',
            col2: 'data2'
        }, {
            col1: 'data1',
            col2: 'data2'
        }];

        vm.options = {
            dataSource: gridData,
            editable: true
        };

        $scope.$on("kendoRendered", function (event) {
            var gridInstance = vm.grid;
            console.log(vm);
            vm.msg = gridInstance === undefined ? "undefined" : "defined";
        });
    }
})();
