迪吉特树未按预期呈现

Question

我正在尝试获取一个json数据渲染道场树。

你可以看到我在做什么 http://jsfiddle.net/F53Ge/38/

                                   require(["dojo/parser","dojo/json","dojo/store/Memory","dijit/tree/ObjectStoreModel","dijit/Tree", "dojo/window"], function              (parser,json,Memory,ObjectStoreModel,Tree,win) {

var data = [{"id":"root","team":[{"teamId":1,"teamname":"JMK_TEST_1","parentteamId":0,"associatedList":[{"type":"9117","number":"1011D1P"}]},{"teamId":174,"teamName":"JJG_PARENT_3","parentteamId":0,"associatedList":[{"type":"8205","number":"062072T"}]},{"teamId":172,"teamName":"JJG_PARENT_1","parentteamId":0,"subteamsList":[{"teamId":175,"teamName":"JJG_Subteam_1","parentteamId":172,"associatedList":[{"type":"8720","number":"12345"}]},{"teamId":176,"teamName":"JJG_Subteam_2","parentteamId":172,"associatedList":[{"type":"8720","number":"12345"}]}],"associatedList":[{"type":"7945","number":"KQZGTNC"}]},{"teamId":221,"teamName":"JJG_Parent_4","parentteamId":0,"subteamsList":[{"teamId":222,"teamName":"JJG_Subteam_4_1","parentteamId":221,"associatedList":[{"type":"9117","number":"10E7683"},{"type":"9119","number":"514DDB2"},{"type":"8233","number":"102FE9P"},{"type":"7978","number":"KDGYKLL"},{"type":"7978","number":"99A9880"}]}]},{"teamId":106,"teamName":"JMK_TEST","parentteamId":0,"subteamsList":[{"teamId":107,"teamName":"JMK_TEST1","parentteamId":106,"subteamsList":[{"teamId":173,"teamName":"JJG_PARENT_2","parentteamId":107,"subteamsList":[{"teamId":178,"teamName":"JJG_Subteam_2_1","parentteamId":173,"associatedList":[{"type":"9117","number":"10E7683"}]}],"associatedList":[{"type":"7945","number":"KQZGTNC"}]}]}]}]}];

var store = new Memory({
    data: data,
    getChildren: function(object){
        return object.team || [];
    }
});
  var model = new ObjectStoreModel({
store: store,
   query: { id:'root' },
    mayHaveChildren: function (item) {
        return "subteamsList" in item;
    }
});
var tree = new Tree({
    model: model,
    showRoot: false,
    autoExpand: true,
    persist: false,
    onClick: function (item, treeNode, e) {
        selectednodeid = this.selectedNode;
        win.scrollIntoView(selectednodeid);
        alert(selectednodeid);
    }
},"oopt_list");
tree.startup();

 });

首先，我没有看到子节点，也不知道如何传递标签，因为它显示列表未定义。

任何帮助，不胜感激。

也让我知道我是否应该使用森林模型。基本上，我正在尝试在树上显示json数据，并想知道用户单击了哪个节点，以便我可以基于此执行一些操作。

问候大黄蜂

Answer 1

要定义哪个属性应该用作标签，您需要在模型上定义"labelAttr"。

您

看不到子节点的原因是，您存储的 idProperty 缺少存储。（或者您在根项"id"上具有不同的 id 属性，而在其他项"teamId"上具有不同的 id 属性）。

使用 ObjectStoreModel 而不是 ForestModel 是正确的。您正在使用内存存储，它是新道场/商店 API 的实现。（ForestModel 只能与较旧的 dojo/data API 一起使用）

在此处查看更新的示例http://jsfiddle.net/F53Ge/42/

require(["dojo/parser","dojo/json","dojo/store/Memory","dijit/tree/ObjectStoreModel","dijit/    Tree", "dojo/window"], function (parser,json,Memory,ObjectStoreModel,Tree,win) {

var data = [{"teamId":"root","subteamsList":[{"teamId":1,"teamName":"JMK_TEST_1","parentteamId":0,"associatedList":[{"type":"9117","number":"1011D1P"}]},{"teamId":174,"teamName":"JJG_PARENT_3","parentteamId":0,"associatedList":[{"type":"8205","number":"062072T"}]},{"teamId":172,"teamName":"JJG_PARENT_1","parentteamId":0,"subteamsList":[{"teamId":175,"teamName":"JJG_Subteam_1","parentteamId":172,"associatedList":[{"type":"8720","number":"12345"}]},{"teamId":176,"teamName":"JJG_Subteam_2","parentteamId":172,"associatedList":[{"type":"8720","number":"12345"}]}],"associatedList":[{"type":"7945","number":"KQZGTNC"}]},{"teamId":221,"teamName":"JJG_Parent_4","parentteamId":0,"subteamsList":[{"teamId":222,"teamName":"JJG_Subteam_4_1","parentteamId":221,"associatedList":[{"type":"9117","number":"10E7683"},{"type":"9119","number":"514DDB2"},{"type":"8233","number":"102FE9P"},{"type":"7978","number":"KDGYKLL"},{"type":"7978","number":"99A9880"}]}]},{"teamId":106,"teamName":"JMK_TEST","parentteamId":0,"subteamsList":[{"teamId":107,"teamName":"JMK_TEST1","parentteamId":106,"subteamsList":[{"teamId":173,"teamName":"JJG_PARENT_2","parentteamId":107,"subteamsList":[{"teamId":178,"teamName":"JJG_Subteam_2_1","parentteamId":173,"associatedList":[{"type":"9117","number":"10E7683"}]}],"associatedList":    [{"type":"7945","number":"KQZGTNC"}]}]}]}]}];

    var store = new Memory({
        data: data,
        idProperty:"teamId",
        getChildren: function(object){
            return object.subteamsList || [];
        }
    });
   var model = new ObjectStoreModel({
    store: store,
       query: { teamId:'root' },
        mayHaveChildren: function (item) {
            console.log("may",item)
            return "subteamsList" in item;
        },labelAttr :"teamName"
    });
    var tree = new Tree({
        model: model,
        showRoot: false,
        autoExpand: true,
        persist: false,
        onClick: function (item, treeNode, e) {
            selectednodeid = this.selectedNode;
            win.scrollIntoView(selectednodeid);
            alert(selectednodeid);
        }
    },"oopt_list");
    tree.startup();

});
