如何根據extjs中的服務器數據檢查treepanel節點？

我有一個基於服務器數據動態生成的樹面板。以下是生成樹面板並將其添加到表單的代碼。如何根據extjs中的服務器數據檢查treepanel節點？

Ext.Ajax.request({ 
    url: '../Get_Menu.php', 
    method: 'POST', 
    success: function (result, request) { 
     var json = result.responseText; 
     var temp = Ext.decode(json); 
     var obj = {}; 
     var item = {}; 
     var menu = {}; 
     var children = []; 
     var module = [{ 
      "text": "Administrator", 
       "leaf": true, 
       "checked": false, 
       "id": "GROUP_ADMIN", 
       "formBind": true, 
       "name": "GROUP_ADMIN" 
     }]; 

     for (var i = 0; i < Object.keys(temp.MENUS).length; i++) { 

      for (var key in temp.MENUS[i]) { 

       for (var n = 0; n < Object.keys(temp.MENUS[i][key]).length; n++) { 

        item = { 
         "text": temp.MENUS[i][key][n], 
          "checked": false, 
          "id": key + "_" + temp.MENUS[i][key][n], 
          "name": key + "_" + temp.MENUS[i][key][n], 
          "formBind": true, 
          "leaf": true 
        }; 
        children.push(item); 
       } 
       menu = { 
        "text": key, 
         "leaf": false, 
         "id": key, 
         "children": children 
       }; 

       module.push(menu); 
       children = []; 
      } 
     } 
     obj = { 
      "text": "Service Quality", 
       "expanded": true, 
       "formBind": true, 
       "children": module 
     }; 

     Ext.getCmp('permissionsTreePanel').setRootNode(obj); 

    }, 
    failure: function (result, request) { 
     Ext.Msg.alert('Error', 'An Error occured...'); 
    } 
});

我有一個基於服務器的數據我收到這樣的檢查樹面板上的節點：

{"PERMISSIONS":{"GROUP_ADMIN":"false","OPERATIONS_MSU":"true","OPERATIONS_SCHEDULE":"false","OPERATIONS_MARKET_DASHBOARD":"false","OPERATIONS_FE_REFERENCE":"true","PRODUCTION_QUICKQC_VOICE":"false","PRODUCTION_QUICKQC_DATA":"false","PRODUCTION_MARKETQC_VOICE":"false","PRODUCTION_MARKETQC_DATA":"false","PRODUCTION_SURGERY":"false","PRODUCTION_FILE_INVENTORY":"false","PRODUCTION_MARKET_TRACKER":"false","PRODUCTION_DRIVE_ROUTE_TRACKER":"false","PRODUCTION_TICKETS":"false","PRODUCTION_ASSETS":"false","MANAGEMENT_DAILY_STATUS":"false","MANAGEMENT_DAILY_PROCESSING":"false","MANAGEMENT_WEEKLY_WORKFLOW":"false","MANAGEMENT_CUSTOMER_QUESTIONS":"false","MANAGEMENT_KPI_PERFORMANCE_METRICS":"false","MANAGEMENT_COLLECTION_METRICS":"false","MANAGEMENT_OPERATIONS_DASHBOARD":"false","MANAGEMENT_PRODUCTION_DASHBOARD":"false","MANAGEMENT_SUPPORT_DASHBOARD":"false","MANAGEMENT_REVENUE_TRACKER":"false","MANAGEMENT_DEPLOYMENT_TRACKER":"false","SUPPORT_TICKETS":"false","SUPPORT_ASSET_MANAGEMENT":"false","SUPPORT_GENERATE_SHIPMENT":"false","TRAINING_RESOURCES":"false","TRAINING_SCHEDULE":"false"}}

請幫我在得到樹面板通過服務器數據檢查節點。

幫助將不勝感激！

非常感謝:)

您不能設置權限serverside嗎？

無論如何，您可以使用「權限」請求中的successcallback。您可以循環訪問權限，然後通過Id獲取treenodes：

var treepanel = Ext.getCmp('permissionsTreePanel'); 
var treestore = treepanel.getStore(); 
var node = treestore.getNodeById('GROUP_ADMIN'); //current permission key 
node.set('checked', true); // current permission value
