JSON的使用

1.JSON在Java中的使用

 1 package com.zdsofe.json;
 2 
 3 import net.sf.json.JSONArray;
 4 import net.sf.json.JSONObject;
 5 
 6 public class Json {
 7    
 8     public static void main(String[] args) {
 9         String json="{'name':'张三','sex':'女','adress':{'city':'武汉','street':'汉阳'}}";
10         JSONObject jion=JSONObject.fromObject(json);
11         System.out.println(jion.get("name"));
12         System.out.println(jion.get("adress"));
13         JSONObject jjon=JSONObject.fromObject(jion.get("adress"));
14         System.out.println(jjon.get("city"));
15         
16          int[] a={1,2,3,4,5};
17          JSONArray jjjo= JSONArray.fromObject(a);
18          System.out.println(jjjo.toString());
19     }
20 }

 9 <script type="text/javascript" src="../js/jquery-1.7.2.js"></script>
10 <script type="text/javascript">
11 $(function(){
12     $(":button").click(function(){

16         if(hobbys.length>0)
17         {
18             
19             for(var i=0;i<hobbys.length;i++)
20             {
21                 arr.push(hobbys[i].value);
22             }
23         }
24         
25         var array=[];
