如何通过dynatree中的ajax调用在url中附加锚点？

Question

我一直试图通过dynatree中的ajax调用来调用java servlet。问题是如何在URL的末尾添加锚点？

http://.../TreeBuilder?caller=Applications

我的jquery代码看起来像这样

onLazyRead: function(node){ 
            node.appendAjax({
                               url: "/TreeBuilder", 
                               data: {"key": node.data.key, 
                                      "mode": "all"
                                      },
                               success: function(node) { 

我的servlet doGet方法看起来像这样

protected void doGet(HttpServletRequest request,HttpServletResponse response) throws ServletException {
    String caller = request.getParameter("caller");
    OrganisationService oService = new OrganisationService();
    try {
        // Object obj = parser.parse(new FileReader("d:\\test.json"));

        // loop array
        JSONArray children = null;
        try {
            children = oService.getChildren(caller);
        } catch (SQLException e) {
            e.printStackTrace();
        }
        logger.info("The children passed are" + children.toJSONString());
        response.setContentType("application/json");
        response.getWriter().write(children.toJSONString());
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

解决了！

函数appendAjax中数据对象中的键值对实际上会像这样附加到url的末尾

http://.../TreeBuilder?key=value

然后我们可以继续在servlet的doGet函数中获取参数。
