下面是我的 JSON。我正在尝试从中创建一棵树，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();
});

但这给了我加载 PSS010010026024 孩子和消息时出错：“无法读取未定义错误的属性‘长度’，应该在 rootID、rootLabel 和 childrenAttrs 中指定什么？

rootID 属性是您要为将要创建的根项目提供的 ID（以便您稍后可以查询它或检查您的树是否位于顶层）。rootLabel 是您希望根属性的标签。childrenAttrs 是您告诉 Tree 特定节点的子节点在哪里的方式。

我不确定您要在代码中执行什么操作，因为您的数据中似乎没有 PSS010010026024，但我建议您在此处查看 ForestTreeModel 的 API 文档：http: //dojotoolkit.org/ api/?qs=1.9/dijit/tree/ForestStoreModel
