无法从meter_Select 填充card_Select。每次更改meter_Select时，我都使用set方法设置和存储。

请参阅我的代码如下：-

var store = new Memory({
data:[
{id:'', label:"Choose one of the cards"},
{id:'testdata1970_05', label:"Mk7ABC Card"},
{id:'testdata1970_10', label:"Mk7CBC Card"},
{id:'testdata2060_03', label:"Mk10BC Card"},
]});

var memoStore1 = new ObjectStore({objectStore:store});
var meter_Select = new Select
        ({store:memoStore1,
        style:{width:'140px'},
        }, "node_meterSelect");
        meter_Select.startup();

var card_Select = new Select
({style:{position: 'absolute', margin: '20px', left:'60px', width:'140px'},
id:'cardSelect'
}, "node_cardSelect");

on(meter_Select, 'change', function(evt)
console.debug('Selected Card = '+ meter_Select.value);
request.post('listofcards.php',{data:{cardX : meter_Select.value},
handleAs:"json"}).then(

function(response)
{var memoStore2 = new Memory({data:response});//ok
console.debug("Loaded into memoStore2 ->" +memoStore2);

var combx = registry.byId('cardSelect');//ok to be undefined.
combx.set('store', memoStore2);
combx.set('value',"");
combx.set('placeHolder',"Choose one of the batch...");
combx.set('searchAttr', 'mfg_code');
combx.startup();
},//function(response)

function(error)//ok
    alert('Getting a list of cards = '+error);
}//function(error)
)//then.});//meter_Select.on

任何的想法？克莱门特

在这个 jsfiddle中，第二个选择是从第一个触发的 Ajax 请求中填充的。

它的症结在这个函数中，这里ObjectStore为select创建了一个新的，并且setStore()调用了该方法来更新dijit：

    function onDataLoaded(response) {
        var memory = new Memory({
            data: response
        });
        var store = new ObjectStore({
            objectStore: memory
        });
        console.log("response", response, "store", store);

        var cardSelect = registry.byId('cardSelect');
        console.log(cardSelect);
        cardSelect.setStore(store);
    }
