如何将dijit.Menu与dijit.Tree的特定节点关联(绑定)

require(["dojo/parser", "dijit/Menu", "dijit/MenuItem", "dijit/PopupMenuItem", "dijit/Tree", "dojo/domReady!"],
  function(parser, Menu, MenuItem, PopupMenuItem, Tree){
    parser.parse();

    // 创建菜单
    var menu = new Menu({
      targetNodeIds: ["treeNode1", "treeNode2"]  // 需要关联菜单的节点的id
    });
    var menuItem1 = new MenuItem({
      label: "菜单项1",
      onClick: function(){
        // 菜单项1的点击事件处理逻辑
      }
    });
    var menuItem2 = new MenuItem({
      label: "菜单项2",
      onClick: function(){
        // 菜单项2的点击事件处理逻辑
      }
    });
    var popupMenuItem = new PopupMenuItem({
      label: "带子菜单的菜单项",
      popup: new Menu({
        targetNodeIds: ["treeNode3"]  // 需要关联子菜单的节点的id
      })
    });
    menu.addChild(menuItem1);
    menu.addChild(menuItem2);
    menu.addChild(popupMenuItem);

    // 创建树形结构
    var tree = new Tree({
      model: treeModel,  // 树形结构的数据模型
      showRoot: false
    }, "treeNodeContainer");

    // 监听节点的右键点击事件
    tree.onOpen = function(item, node){
      menu.bindDomNode(node.labelNode);  // 将菜单与节点关联起来
    };
  }
);
