如何從JSON中創建樹[林木樹模型] ...？

Question

以下是我的JSON。我試圖創建一個樹離開這裏， 我試着用下面的代碼片段：

require(["dijit/Tree", "dojo/data/ItemFileReadStore", "dijit/tree/ForestStoreModel", "dojo/domReady!"], 
     function(Tree, ItemFileReadStore, ForestStoreModel){ 
    var store = new ItemFileReadStore({ 
     url: "/om/web/em/tree.json" 
}); 

    var treeModel = new ForestStoreModel({ 
     store: store, 
     query: {id: 'aid'}, 
     rootId: "PSS-32", 
     rootLabel: "P", 
     childrenAttrs: ['eqList'] 
    }); 

    var myTree = new Tree({ 
     model: treeModel 
    }, "treeOne"); 
    myTree.startup(); 
}); 

但是，這是給我的錯誤裝載PSS010010026024兒童和消息：「無法讀取未定義錯誤的特性‘長度’，我應該在rootID，rootLabel和childrenAttrs指定？

Answer 1

的rootID屬性是你想給將要創建（這樣你可以，如果你的樹以後查詢，或檢查根項目什麼ID是在頂層）。rootLabel是你想要的根屬性的標籤。孩子們是如何喲你告訴樹特定節點的孩子。

我不知道你想在你的代碼，這樣做雖然因爲您的數據似乎並不具有PSS010010026024它什麼，但我會建議您檢查出的ForestTreeModel這裏的API文檔：http://dojotoolkit.org/api/?qs=1.9/dijit/tree/ForestStoreModel
