Dojo ComboBox 未填充数据

Question

不确定我做错了什么，但我已按照解释的方法进行操作。我想，我也将对象添加到存储对象中。但同样没有反映在 UI 上。下拉菜单仍然是空白的。有人可以帮忙吗。

我的选择框代码：

<div class="ecmSearchFormInputArea">
    <table class="ecmSearchFormInputArea">
                <tr>
                    <td class="propertyRowLabel">
                        <label><span class="mandatory_red"></span>Cost Center :</label>&nbsp;

                        <select data-dojo-attach-point="costCenter" id="costCenter"
                        data-dojo-type="dijit/form/FilteringSelect" style="width: 18em;" 
                        data-dojo-attach-event="onChange:loadDocStacks">
                        </select>
                    </td>
                </tr>
            </table>                                              
         </div>

我的 JS

postCreate: function() {
        this.logEntry("postCreate");

        //Trying to populate Combobox
        var storeData = {
                identifier: 'costCenter',
                items: []
            }
        var jsonObj = [{
            costCenter: 'sc1'
        },
        {
            costCenter: 'sc2'
        }]

        dojo.addOnLoad(function () {
        var costCenterStore = new dojo.data.ItemFileWriteStore({ data: storeData });

        for (var i = 0; i < jsonObj.length; i++) {
            alert ("value of i = " + jsonObj[i].costCenter);
            costCenterStore.newItem(jsonObj[i]);
        }
        var serviceFilterSelect = dijit.byId('costCenter');
        alert ("serviceFilterSelect " + serviceFilterSelect);
        alert ("costCenterStore " + costCenterStore);

        serviceFilterSelect.attr('store', costCenterStore);
        });
        //Trying to populate Combobox

        this.logExit("postCreate");
    },

FOR 循环中的警报显示正确的数据。我错过了什么吗？

添加标签属性和标识符。因为这将用作填充的标签。

var jsonObj = [{
            costCenter: 'sc1', name: 'label1'
        },
        {
            costCenter: 'sc2', name: 'label2'
        }];

var storeData = {
                identifier: 'costCenter', label: 'name',
                items: []
            };
