将JSON绑定到DevExtreme数据网格
将数据加载到DevExtreme datagrid时遇到问题。 如果我试着用这个示例代码示例:
var orders = new DevExpress.data.CustomStore({
load: function (loadOptions) {
var deferred = $.Deferred(),
args = {};
if (loadOptions.sort) {
args.orderby = loadOptions.sort[0].selector;
if (loadOptions.sort[0].desc)
args.orderby += " desc";
}
args.skip = loadOptions.skip || 0;
args.take = loadOptions.take || 12;
$.ajax({
url: "http://js.devexpress.com/Demos/WidgetsGallery/data/orderItems",
data: args,
success: function(result) {
deferred.resolve(result.items, { totalCount: result.totalCount });
},
error: function() {
deferred.reject("Data Loading Error");
},
timeout: 5000
});
return deferred.promise();
}
});
var grid = $("#gridContainer").dxDataGrid({
dataSource: {
store: orders
},
paging: {
pageSize: 12
},
pager: {
showPageSizeSelector: true,
allowedPageSizes: [8, 12, 20]
},
columns: [
"OrderNumber", "OrderDate", "StoreCity", "StoreState", "Employee", {
dataField: "SaleAmount",
format: "currency"
}
]
}).dxDataGrid("instance");
它的工作原理,所以执行devextreme datagrid的问题我没有问题。 但是当我想将数据源设置为我的数据时,它不起作用。 我有ASP.NET mvc应用程序。 一个动作GetData以JSON格式返回数据。 如果我更改网址为:
url:"/Home/GetData"
或url:"localhost:port/Home/GetData/
add: type:"GET"
并更改列的名称以在JSON响应中命名我的列,但不起作用。返回JSON格式的数据我是新技术,是我做错了什么?我没有在API参考中找到,如何从MVC动作绑定JSON数据,也许我错了搜索。
确保JSON中包含以下字段:
这是我的JSON结果操作,是的,代码中的列名与JSON结果操作中的列名相同。
[{"Name":"Jan","Surname":"Novak","Department":"IT","Address":"Address 1"},{"Name":"Jan ","Surname":"Datel","Department":"HR","Address":"Address 2"},{"Name":"Josef","Surname":"Novotny","Department":"IT","Address":"Address 2"}]
你应该在dxDataGrid中设置你的列(在你的json中:“Name”,“Surname”,“Department”,“Address”):
var grid = $("#gridContainer").dxDataGrid({
dataSource: {
store: orders
},
paging: {
pageSize: 12
},
pager: {
showPageSizeSelector: true,
allowedPageSizes: [8, 12, 20]
},
columns: [
"Name", "Surname", "Department", "Address"
]
}).dxDataGrid("instance");
你也可以用最小的设置创建网格:
var grid = $("#gridContainer").dxDataGrid({
dataSource: {
store: orders
}
}).dxDataGrid("instance");
