將頁(yè)面上javascript中的json代碼傳入服務(wù)器

1、將頁(yè)面上javascript中的json代碼傳入服務(wù)器，然后返回給頁(yè)面處理后(JSONObject)的結(jié)果：導(dǎo)入要用到的包寫(xiě)頁(yè)面代碼如下： base href= JSON Example function send()alert(kk);var json = userName:吳偉成,age:23,favorite:name:football,time:one hour,name:basketball,time:two hours;var jsonStr = JSON.stringify(json);var url = JSONExample?json=+encodeURI(jsonStr)+

2、&timeStamp=+(new Date();$.get(url,null,function(data)$(#show).html(data););alert(kkk); 寫(xiě)服務(wù)器端代碼(Servlet):package com.fit;import java.io.IOException;import java.io.PrintWriter;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;impor

3、t javax.servlet.http.HttpServletResponse;import net.sf.json.JSONArray;import net.sf.json.JSONObject;public class JSONExample extends HttpServlet private static final long serialVersionUID = 1L;protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IO

4、Exception String jsonStr = request.getParameter(json); String json = new String(jsonStr.getBytes(iso8859-1),UTF-8); response.setContentType(type=text/html;charset=UTF-8); /將獲取的字符串字符串轉(zhuǎn)換成JSONObject對(duì)象 JSONObject jsonObject = JSONObject.fromObject(json); PrintWriter out = response.getWriter(); out.print

5、ln(用戶(hù)名：+jsonObject.getString(userName)+ 年齡：+jsonObject.getInt(age); /下面向葉面上輸出favorite信息 JSONArray arr = jsonObject.getJSONArray(favorite); /獲取數(shù)組中的對(duì)象 JSONObject arrObjOne = arr.getJSONObject(0); JSONObject arrObjTwo = arr.getJSONObject(1); /輸出獲取對(duì)象中的內(nèi)容（數(shù)組中的） out.println(愛(ài)好：+arrObjOne.getString(name)+ +arrObjOne.getString(time); Overrideprotected void doGet(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException / TODO Auto-generated method stubdoPost(request, response
