我試圖以編程方式從json文件創建dojo樹。問題在於我的json對象引用他們的父母而不是像一些例子中的孩子。 不幸的是我的輸出看起來只像這樣:基於ItemFileReadStore和父類型的Dojo Tree
我已經JavaScript代碼如下:
<script type="text/javascript">
require(["dijit/Tree", "dojo/data/ItemFileReadStore", "dijit/tree/ForestStoreModel", "dijit/tree/ObjectStoreModel", "dojo/domReady!"],
function(Tree, ItemFileReadStore, ObjectStoreModel, ForestStoreModel){
var store = new ItemFileReadStore({
url: "/_data/test.json",
getChildren: function(object){
return this.query({F_TopLevelCategoryID: object.P_CategoryID});
}
});
var myModel = new ObjectStoreModel({
store: store,
labelAttr:'CategoryName',
query: {"P_CategoryID": 0}
});
var myTree = new Tree({
model: myModel
}, "treeOne");
myTree.startup();
});
</script>
JSON文件如下所示:
{ "identifier" : "P_CategoryID",
"label" : "CategoryName",
"items" : [ { "CategoryName" : "Category 1",
"F_TopLevelCategoryID" : 0,
"P_CategoryID" : 1
},
{ "CategoryName" : "Category 2",
"F_TopLevelCategoryID" : 1,
"P_CategoryID" : 2
},
{ "CategoryName" : "Category 3",
"F_TopLevelCategoryID" : 1,
"P_CategoryID" : 3
},
{ "CategoryName" : "Category 4",
"F_TopLevelCategoryID" : 1,
"P_CategoryID" : 4
},
{ "CategoryName" : "Category 5",
"F_TopLevelCategoryID" : 3,
"P_CategoryID" : 5
},
{ "CategoryName" : "Category 6",
"F_TopLevelCategoryID" : 4,
"P_CategoryID" : 6
},
{ "CategoryName" : "Category 7",
"F_TopLevelCategoryID" : 4,
"P_CategoryID" : 7
},
{ "CategoryName" : "Category 8",
"F_TopLevelCategoryID" : 0,
"P_CategoryID" : 8
},
{ "CategoryName" : "Top Level Category",
"P_CategoryID" : 0
}
]
}
在哪裏問題?
這個作品很有魅力,非常感謝! 我已經有了一個工作片段,內存存儲就緒,並且可以添加請求函數以從URL中檢索數據。 :) – gotcha
@gotcha很高興它爲你工作! – Tom
