推荐答案
为了检索选定的 ID，您可以使用 dataItem 对象并通过 change事件:
In order to retrieve the selected Id you can use the dataItem object and access the id within it with change event:
var dataItem = e.sender.dataItem();
$('#id').text(dataItem.id);
这也能让您访问对象内的任何数据:
This will get you access to any data within the object too:
$('#name').text(dataItem.name);
工作示例
HTML
<input id="dropdownlist" /><br/>
<span id="id" >Id</span><br/>
<span id="name" >Name</span><br/>
JavaScript
$("#dropdownlist").kendoDropDownList({
dataSource: [
{ id: 1, name: "Apples" },
{ id: 2, name: "Oranges" }
],
dataTextField: "name",
dataValueField: "id",
index: 1,
change: onChange
});
function onChange(e) {
var dataItem = e.sender.dataItem();
$('#id').text(dataItem.id);
$('#name').text(dataItem.name);
};
