Question

以下是我的JSON。我试图用这个创建一棵树，我尝试使用以下代码段：

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();
});

但是这给我加载错误PSS010010026024儿童和消息：＆＃34;无法读取属性＆＃39;长度＆＃39;未定义的错误，应该在rootID，rootLabel和childrenAttrs中指定什么？

Answer 1

rootID属性是您要为将要创建的根项目提供的ID（以便您以后可以查询它或检查您的树是否位于顶层）。 rootLabel是你想要的root属性的标签。 childrenAttrs就是你如何告诉Tree特定节点的孩子在哪里。

我不确定您在代码中尝试做什么，因为您的数据似乎没有PSS010010026024，但我建议您在这里查看ForestTreeModel的API文档：http://dojotoolkit.org/api/?qs=1.9/dijit/tree/ForestStoreModel
