如何更新dojox.Grid以顯示最新數據?dojo datagrid和itemfilereadstore

起初,我創建的空店, 然後我改變了數據包含的東西, 創建新的數據存儲與新的數據 ,然後將數據存儲格設置爲新店。

在大多數示例中,人們在初始化商店時使用url而不是數據。

那麼如何更新網格以顯示最新的商店?

// 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);

電網應該更新,當您用新的數據存儲調用'setStore'。我認爲你的代碼是正確的。你的代碼有什麼問題?網格沒有更新? – 2010-05-20 02:27:18

的問題是在這裏:

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

你不能添加新的數據ItemFileReadStore(僅用於讀), 必須使用ItemFileWriteStore
