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);

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);
                  };
