我想用从 web 服务返回的复杂 json 填充网格。我的 json 包含两件事:
- 数据:包含将填充网格的记录的数组
- 列:具有网格配置(布局)的数组
我已经通过指定 schema.data 成功地用“数据”填充了网格。
我的问题是网格配置(布局)。我在数据源的事件中获取列数组,requestEnd
并将其添加到customersSource
(数据源)中,以便我可以在 gridOptions 中访问它。
问题是,即使当我记录customersSource
对象时,我看到我添加的 cols 数组在那里并且填充了$scope.mainGridOptions.columns
未设置为的正确数据customersSource.cols
。
我认为这可能与customersSource.cols
异步设置的事实有关,但角度不应该通过它的数据绑定来处理这个问题?
此外,我在Data source vs. Angular中读到过,我可能必须将某些东西设置为 Observable,但我对到底该怎么做感到困惑。
我怎样才能解决这个问题?
这是我的代码:
var customersSource = new kendo.data.DataSource({
transport: {
read: {
url: "http://....",
dataType: "json"
}
},
schema: {
data: "data"
},
requestEnd: function (e) {
this.cols = e.response.columns;
}
});
$scope.mainGridOptions = {
dataSource: customersSource, // OK
columns: customersDataSource.cols, // undefined - uses default
height: 500,
scrollable: true,
selectable: true
};
这是我的 JSON

编辑 我为我的测试项目创建了一个 plunker。如您所见,我可以填充网格,但 mainGridOptions.columns 有问题。任何帮助都感激不尽! http://plnkr.co/edit/5pjFQGkgTivqVkxsFBse
