jquery.treeview的问题

Question

请我用jq.treeview展示一颗树后，如何让脚本自动折叠开树并选中第一个叶子结点呢？
其它非本叶子的上级不用折叠开。希望有人能帮助我谢谢了。

    $(function () {
    $("#divTree")
    .jstree({ "plugins" : ["themes","html_data","checkbox","ui"],"themes": {
                        "theme": "classic",
                        "dots": true,
                        "icons": true
                    }
             })
        // 1) if using the UI plugin bind to select_node
    .bind("select_node.jstree", function (event, data) { 
        var href= data.rslt.obj.find("a").attr("href");
        if(href!="#"){
           /// 单击人名 如果是选中 讲按钮设置成不选择
           if($("#divTree").jstree("is_checked",data.rslt.obj)){
             $("#divTree").jstree("uncheck_node",data.rslt.obj);
           }
           else{
             $("#divTree").jstree("check_node",data.rslt.obj);
           }
        }else///点击父节点伸展
        {
            $("#divTree").jstree("toggle_node", data.rslt.obj);
        }
    })
        .bind("open_node.jstree", function (e, data) {
        // data.inst is the instance which triggered this event
        //data.inst.select_node("#phtml_2", true);
        //alert(1);
        })
    ///默认 展开TZGW
    setTimeout(function () { $.jstree._reference("#TZGW").open_node("#TZGW"); }, 200);     
    });PAGE HTML                 <div id="divTree">
                    <ul>
                        <li id="TreeHead" class="jstree-open"><a href="#">消息记录</a>
                            <ul>
                                <li id="TZGW"><a href="#">投资顾问<span id="DivCountTZGW" runat="server"></span></a>
                                    <ul>
                                        <asp:Repeater ID="RepeaterTZGW" runat="server">
                                            <ItemTemplate>
                                                <li id="<%#Eval("LoginName")%>"><a href="javascript:void(0)" target="_ifhistoryMessage">
                                                    <%#Eval("LoginName")%></a> </li>
                                            </ItemTemplate>
                                        </asp:Repeater>
                                    </ul>
                                </li>
                                <li id="KH"><a href="#">我的客户<span id="DivCountKH" runat="server"></span></a>
                                    <ul>
                                        <asp:Repeater ID="RepeaterKH" runat="server">
                                            <ItemTemplate>
                                                <li id="<%#Eval("LoginName")%>"><a href="javascript:void(0)" target="_ifhistoryMessage">
                                                    <%#Eval("LoginName")%></a> </li>
                                            </ItemTemplate>
                                        </asp:Repeater>
                                    </ul>
                                </li>
                            </ul>
                        </li>
                    </ul>
                </div>应该能得到你想要的！！！     setTimeout(function () { $.jstree._reference("#TZGW").open_node("#TZGW"); }, 200);
这个是主要的
