从现有的创建新的Kendo UI DataSource

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了从现有的创建新的Kendo UI DataSource相关的知识，希望对你有一定的参考价值。
我有两个使用相同后端数据的Kendo UI Combo-Box，但是如果我对它们两个应用相同的Kendo UI DataSource，那么也可以在第二个过滤器上完成过滤（我不想发生）。
有没有办法将现有数据源的数据应用到新的数据源中，这样我就可以保存一个服务调用。
<select runat="server" id="combo1"></select>
<select runat="server" id="combo2"></select>
<script>
var data = [
{ title: "Star Wars: A New Hope", year: 1977 },
{ title: "Star Wars: The Empire Strikes Back", year: 1980 },
{ title: "Star Wars: Return of the Jedi", year: 1983 }
];
var DS1 = new kendo.data.DataSource({
data: data
});
$("#combo1").kendoComboBox({
placeholder: "Select",
dataValueField: "year",
dataTextField: "title",
filter: "contains",
dataSource: DS1
});
$("#combo2").kendoComboBox({
placeholder: "Select",
dataValueField: "year",
dataTextField: "title",
filter: "contains",
dataSource: DS1
});
</script>

答案
试试这个 ：
var data = [
{ title: "Star Wars: A New Hope", year: 1977 },
{ title: "Star Wars: The Empire Strikes Back", year: 1980 },
{ title: "Star Wars: Return of the Jedi", year: 1983 }
];
var DS1 = new kendo.data.DataSource({
data: data
});
var DS2 = new kendo.data.DataSource({
data: data
});
$("#combo1").kendoComboBox({
placeholder: "Select",
dataValueField: "year",
dataTextField: "title",
filter: "contains",
dataSource: DS1
});
$("#combo2").kendoComboBox({
placeholder: "Select",
dataValueField: "year",
dataTextField: "title",
filter: "contains",
dataSource: DS2
});<!DOCTYPE html>
