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：
<"1.0" encoding="UTF-8""2.4"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<servlet>
<servlet-name>getDataServlet</servlet-name>;
<servlet-class>testTree.TestTree</servlet-class>;
</servlet>
<servlet-mapping>
<servlet-name>getDataServlet</servlet-name>;
<url-pattern>/getData</url-pattern>;
</servlet-mapping>
</web-app>
JSP页面：
<!DOCTYPE html> <HTML> <HEAD> <TITLE> ZTREE DEMO - Simple Data</TITLE> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> <link rel="stylesheet" href="css/demo.css" type="text/css"> <link rel="stylesheet" href="css/zTreeStyle/zTreeStyle.css" type="text/css"> <script type="text/javascript" src="/UploadFiles/2021-04-02/jquery-1.4.4.min.js">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<HashMap<String,Object list = new ArrayList<HashMap<String,Object(); for(int i = 0; i < 5; i++){ HashMap<String,Object> hm = new HashMap<String,Object>(); //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。
