      function filter (Treeid, ParentNode, childnodes) {if (!childnodes) return null; 
      For (var i=0, l=childnodes.length; i<l; i++) {childnodes[i].name = Childnodes[i].name.replace (', '); 
    return childnodes; 
      var znodes =[{id:1, pid:0, Name: "ParentNode 1", open:true}, {id:11, pid:1, Name: "ParentNode 11"}, {id:111, pid:11, Name: "Leafnode"}, {id:112, pid:11, Name: "Leafnode 112"}, {id:113, pid:11, Nam E: "Leafnode 113"}, {id:114, pid:11, Name: "Leafnode 114"}, {id:12, pid:1, Name: "ParentNode"}, {I d:121, Pid:12, Name: "Leafnode 121"}, {id:122, pid:12, Name: "Leafnode 122"}, {id:123, pid:12, Name: "Leafnod E 123 "}, {id:13, pid:1, Name:" ParentNode ", isparent:true}, {id:2, pid:0, Name:" ParentNode 2 ", Isparent: 
    true}]; $ (document). Ready (function () {$.fn.ztree.inIt ($ ("#treeDemo"), setting, znodes); 
    }); --> </SCRIPT> </HEAD> <BODY>  

 action code:

public class Testtree extends HttpServlet {@Override public void doget (HttpServletRequest request, Httpservletre 
    Sponse response) throws Servletexception, IOException {//System.out.println ("--------doget--------"); 
  This.dopost (request, response); @Override public void DoPost (HttpServletRequest request, httpservletresponse response) throws Servletexception, 
    IOException {//System.out.println ("--------doPost--------"); 
    String id = request.getparameter ("id"); 
    String name = Request.getparameter ("name"); 
    String level = Request.getparameter (' level '); 
    String Otherparam = Request.getparameter ("Otherparam"); 
    System.out.println (id + "|" + name + "|" + Level + "|" + Otherparam); 
    Jsonobject json = new Jsonobject (); 

The above is the jquery ztree asynchronous loading instance to share to everybody, hoped that everybody learns the asynchronous loading technology to be helpful.
