本文实例讲解了jquery ztree异步加载，分享给大家供大家参考，具体内容如下
web.xml中Servlet配置如下：
<?xml version="1.0" encoding="UTF-8"?>getDataServlet ;testTree.TestTree ;getDataServlet ;/getData ;
JSP页面：
ZTREE DEMO - Simple Data 最简单的树 -- 简单 JSON 数据
[ 文件路径: core/simpleData.html ]
Action代码：
public class TestTree extends HttpServlet {
@Override
public void doGet(HttpServletRequest request, HttpServletResponse 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();
List> list = new ArrayList>();
for(int i = 0; i < 5; i++){
HashMap hm = new HashMap(); //最外层，父节点
hm.put("id", id + i);//id属性 ，数据传递
hm.put("name", id + i); //name属性，显示节点名称
hm.put("pId", id);
list.add(hm);
}
JSONArray arr = new JSONArray(list);
json.put("success", true);
json.put("arr", arr);
System.out.println("--------json------" + json.toString());
response.getWriter().write(arr.toString());
// response.getWriter().write(json.toString());
// response.getWriter().write("[{pId:'2',name:'20',id:'20'}]");
}
}
以上就是jquery zTree异步加载实例分享给大家，希望对大家学习异步加载技术有所帮助。
