HTML代码如下：

<body class="claro">
            <div id="rootlessTree" data-dojo-type="dijit/Tree"></div>
</body>

Js代码如下：

require([
    "dojo/dom",
                    "dojo/json",
                    "dojo/store/Memory",
                    "dijit/tree/ObjectStoreModel",
                    "dijit/Tree",
                    "dojo/domReady!"
], function(dom, json, Memory, ObjectStoreModel, Tree){
    var ss=‘[{ "id":0, "name": "test", "aa": "ss"},{"id":1,"name":"a","Fartherid":0},{"id":8,"name":"b","Fartherid":0},{"id":11,"name":"c","Fartherid":0},
{"id":237,"name":"d","Fartherid":0},{"id":238,"name":"e","Fartherid":0},{"id":82,"name":"f","Fartherid":0},{"id":233,"name":"g","Fartherid":0},
{"id":246,"name":"h","Fartherid":0},{"id":9,"name":"i","Fartherid":8},{"id":10,"name":"j","Fartherid":8},{"id":12,"name":"k","Fartherid":11},
{"id":13,"name":"l","Fartherid":11},{"id":18,"name":"1","Fartherid":11},{"id":19,"name":"12","Fartherid":11},{"id":235,"name":"m","Fartherid":233},
{"id":239,"name":"n","Fartherid":238},{"id":245,"name":"o","Fartherid":238}]‘;
     var dt = JSON.parse(ss);
    continentStore = new Memory({
        data: dt
    });
    continentStore.getChildren = function(object){
        return this.query({Fartherid: this.getIdentity(object)});//Fartherid为绑定的父节点id
    };
    continentModel = new ObjectStoreModel({
    store: continentStore,
    query: {id:0},                   //将该目录树绑定道节点为0的id上
    mayHaveChildren: function(item){ //如果子节点没有内容，图标就显示成文档
        console.log(item);
        if(item.id===0) return true;
        for(var i=0;i<dt.length;i++){
            if(item.id===dt[i].Fartherid) return true;
        }
        return false;
    }
    });
    var governmentTree = new Tree({
                                model: continentModel,
                                onOpenClick: true,
                                showRoot:true,                  //是否显示跟节点
                                onl oad: function(){             //加载完毕
                                    console.log("plantTree");
                                },
                                onClick: function(item){       //单击事件
                                    console.log(item);
                                },
                                persist: false
                            }, "rootlessTree");
                            governmentTree.startup();
});
