Binding existing Kendo grid to a new JSON object
提问by Maven
I have following kendoGridon my page that on load receives JSONobject from the specified URL.
kendoGrid我的页面上有以下内容，加载时JSON从指定的 URL接收对象。
But later i want to bind it to some other JSONdata received from other source. Is there a way a can bind-refresh existing data containing grid with a new JSONobject?
但后来我想将它绑定JSON到从其他来源收到的其他一些数据。有没有办法可以使用新JSON对象绑定刷新包含网格的现有数据？
$('#grid').kendoGrid({
sortable: true,
groupable: true,
scrollable: true,
pageable: {
pageSizes: 9
},
dataSource: {
transport: {
read: {
url: "../Get/JsonData",
dataType: "Json"
}
}
},
columns: [
{ field: "name", title: "Name", width: 100 },
... ...
]
});

You could either replace all the data in the DataSource with:
您可以将 DataSource 中的所有数据替换为：
var newData = [ "some", "data", "array" ];
var gridWidget = $('#grid').data("kendoGrid");
gridWidget.dataSource.data(newData);
Or you can give the grid a whole new DataSource (I recommend this approach):
或者你可以给网格一个全新的数据源（我推荐这种方法）：
var newData = new kendo.data.DataSource({
data: [ "some", "data", "array" ]
});
var gridWidget = $('#grid').data("kendoGrid");
gridWidget.setDataSource(newData);
and of course newDatain my example would just be whatever data is returned from your function.
当然，newData在我的示例中，只是从您的函数返回的任何数据。

Is the structure of the new JSON the same (same columns and same data model)? If so then yes, just play with transport.reador transport.read.urland instead of defining it as a stringdefine it as a function that returns either one or the other.
新 JSON 的结构是否相同（相同的列和相同的数据模型）？如果是，那么是的，只需使用transport.readortransport.read.url和而不是将其string定义为将其定义为返回一个或另一个的函数。
Remember that transport.readmight be an object or a function. Same happens for transport.read.url
请记住，它transport.read可能是一个对象或一个函数。同样发生在transport.read.url
