 对应action类中加上xml<userdata name="url">www.baiud.com</userdata>

在javascript中调用方法

var id=tree.getSelectedItemId();
    var text= tree.getUserData(id,"url");   获取对应的url地址

 

而action中需要写上对应的

 public String getCarTypeXML() throws Exception { 
  
  System.out.println("diaoyong");
  
      Document document = DocumentHelper.createDocument(); 
      Element root = document.addElement("tree"); 
    root.addAttribute("id", "0"); 
  
    Element item = root.addElement("item"); 
     item.addAttribute("text", "我的工作台"); 
    item.addAttribute("id", "work console"); 
    item.addAttribute("open", "1");
    item.addAttribute("im0", "folderClosed.gif"); 
    item.addAttribute("im1", "folderOpen.gif"); 
     item.addAttribute("im2", "folderClosed.gif"); 
 
      Element subItem = item.addElement("item"); 
       subItem.addAttribute("text", "代办事宜"); 
     subItem.addAttribute("id", "working"); 
//     subItem.addAttribute("open", "1");
     subItem.addAttribute("im0", "folderClosed.gif"); 
     subItem.addAttribute("im1", "folderOpen.gif"); 
     subItem.addAttribute("im2", "folderClosed.gif");
//     subItem.addAttribute("im0", "book_titel.gif"); 
//     subItem.addAttribute("im1", "fbook.gif"); 
//      subItem.addAttribute("im2", "book_titel.gif"); 
//      subItem = item.addElement("item"); 
//     subItem.addAttribute("text", "代办事宜2"); 
//      subItem.addAttribute("id", "working"); 
//        subItem.addAttribute("im0", "book_titel.gif"); 
//     subItem.addAttribute("im1", "fbook.gif"); 
//     subItem.addAttribute("im2", "book_titel.gif"); 
    
    
     Element subitem1=subItem.addElement("item");
     subitem1.addAttribute("text", "代办事宜2-1");
     subitem1.addAttribute("id", "working-01");
     subitem1.addAttribute("im0", "book_titel.gif");
     subitem1.addAttribute("im1", "fbook.gif"); 
     subitem1.addAttribute("im2", "book_titel.gif"); 
     Element sbu1_1=subitem1.addElement("userdata");
     sbu1_1.addAttribute("name", "url");
     sbu1_1.addText("www.baidu.com");
    
   
    
    
     subitem1=subItem.addElement("item");
     subitem1.addAttribute("text", "代办事宜2-2");
     subitem1.addAttribute("id", "working-02");
     subitem1.addAttribute("im0", "book_titel.gif");
     subitem1.addAttribute("im1", "fbook.gif"); 
     subitem1.addAttribute("im2", "book_titel.gif");
    
    
    
    
  
    
    
    
     String content = document.asXML(); 
      System.out.println(content); 
     HttpServletResponse response = ServletActionContext.getResponse(); 
      response.setContentType("text/xml; charset=UTF-8"); 
      response.setHeader("Cache-Control", "no-cache"); 
   
      PrintWriter pw=response.getWriter(); 
      pw.write(content); 
     pw.flush(); 
     pw.close(); 
     return null;
  } 

 

 

对应javascript

 <body>
  <div id="treeboxbox_tree" style="width:300px; height:200px;background-color:#f5f5f5;border :1px solid Silver; "/> 
 <script type="text/javascript">
 
 
 
 

  tree=new dhtmlXTreeObject("treeboxbox_tree","100%","100%",0); 
    // tree.setImagePath("imgs/csh_bluefolders/"); 
    tree.setImagePath("js/csh_vista/");
      tree.enableCheckBoxes(1); 
     tree.enableDragAndDrop(0); 
     tree.enableThreeStateCheckboxes(true);
     var url="<%=basePath%>/example/getCarTypeXML.action";
      tree.setOnClickHandler(tonclick)
     tree.loadXML(url); 
   
      
        function tonclick()
        {
           var id=tree.getSelectedItemId();
           var text= tree.getUserData(id,"url");  
           alert(text);

        }
       
 
 </script>
  </body>
