如何更新dojox.Grid以显示最新数据？

最初我创建了空店，然后我改变了数据以包含某些东西，使用新数据创建新的数据存储然后将网格数据存储区设置为新存储区。

在大多数示例中，人们在初始化商店时使用网址而不是数据。

那么如何更新网格以显示最新商店？

 // Use empty grid,
var emptyData = { identifier: "UID_T", label: "UID_T", items: [] };
var lgaNameSelectionStore = new dojo.data.ItemFileReadStore({data: emptyData}); 

var lgaNameGridLayout = [
        {name : "<span title='Agency'>Agency</span>", field : "AGENCY", width : "7em"},
        {name : "<span title='Project Description'>Project Description</span>", field : "ProjectDes", width : "20em"},
        {name : "<span title='Description'>Description</span>", field : "CTPPD_DESC", width : "12em", },

    ];

var lgaNameContainer = new dijit.layout.BorderContainer({       
            style: "width: 100%; height: 100%",
            gutters: false,
            design: "headline"
    },"lgawinuid");

lgaNameGrid = new dojox.grid.DataGrid({
        store: lgaNameSelectionStore,
        region: "center",
        structure: lgaNameGridLayout,
        selectionMode: "none",
        noDataMessage: "No results found."
    });

lgaNameContainer.addChild(lgaNameGrid);
lgaNameContainer.startup();


//data is changed, so need to update the grid   
var data3 = { identifier: "UID_T", label: "UID_T", items: [{"UID_T" : "I333","AGENCY" : "RTA","CTPPD_DESC" : "M5","ProjectDes" : "Filtration","location" : ""}]};

lgaNameSelectionStore = new dojo.data.ItemFileReadStore({data: data3});
lgaNameGrid.setStore(lgaNameSelectionStore);

Answer 1

问题在于：

lgaNameSelectionStore = new dojo.data.ItemFileReadStore({data: data3});

您无法向ItemFileReadStore添加新数据（仅适用于READ），你必须使用ItemFileWriteStore

dojo datagrid和itemfilereadstore
