    var store = new dojo.data.ItemFileReadStore( { data: {
        identifier: "name",
        items: [
        {name:"Alabama", id:"AL"},
        {name:"Alaska", id:"AK"},
        {name:"American Samoa", id:"AS"},
        {name:"Arizona", id:"AZ"},
        {name:"Arkansas", id:"AR"},
        {name:"Armed Forces Europe", id:"AE"},
        {name:"Armed Forces Pacific", id:"AP"},
        {name:"Armed Forces the Americas", id:"AA"},
        {name:"California", id:"CA"},
        {name:"Colorado", id:"CO"},
        {name:"Connecticut", id:"CT"},
        {name:"Delaware", id:"DE"}
    ]
    }});

        var comboBox = new dijit.form.ComboBox({
        id: "stateSelect",
        name: "state",
        value: "-- Select --",
        store: store,
        searchAttr: "name"
    }, "stateSelect");

我有文本框搜索数据ID。

我如何做。

推荐答案

comboBox.item is

comboBox.item is a reference to the currently selected element.

您可以通过以下方式获取您的项目的ID和值：

You can get the id and value of your item through :

var id = store.getValue(comboBox.item, "id");
var name = store.getValue(comboBox.item, "name");

然后使用id和name在任何你需要的地方显示值...

Then you use id and name to display the values wherever you need to...
