//将JSON字符串转换为JSON对象的一些方法

//将JSON字符串转换为JSON对象的一些用法

(function (){

var str = {"name":"张三","age":20};//JSON对象

alert(str.name);alert(str.age);//直接取JSON对象的值

//将JSON字符串转换为JSON对象

var str = "{\"name\":\"张三\",\"age\":\"21\"}";//JSON字符串转义不用系统/和dos一致用\

var obj = eval('(' + str + ')');//使用eval函数将JSON字符串转换为JSON对象 alert(obj.name);alert(obj.age);

var str = '{"name":"张三","age":22}';//JSON字符串

var obj = (new Function("return " + str))(); //使用new Function()形式将JSON字符串转换为JSON对象

alert(obj.name);alert(obj.age);

//将JSON对象转换为JSON字符串

//var straa = {"name":"李四","age":"20"};//JSON对象

//var newJSONtext = straa.toJSONString();//貌似没有原生方法

//alert("JSON对象转换为JSON字符串: "+newJSONtext);

})();//(function (){})();自动执行匿名函数

function showJSON() {

//效果一

var user =

解析JSON：

package com.lastexam.weatherforecast;

import java.util.ArrayList;

import java.util.Scanner;

import net.sf.json.JSONArray;

import net.sf.json.JSONObject;

public class ParseJSON

{

public static void main(String []args)

{

Scanner in=new Scanner(System.in);

System.out.println("请输入数据：");

String string=in.next();

System.out.println(ParseResult(string));

Location location=new Location();

location=ParseLocation(ParseResult(string)); System.out.println(location.toString());

//实时天气情况解析完毕

RealNow now=new RealNow();

now=ParseNow(ParseResult(string));

System.out.println(now.toString());

//天气预报解析完毕

WeatherDaily []daily=ParseDaily(ParseResult(string)); for(int i=0;i<daily.length;i )

{

System.out.println(daily[i].toString()); }

//suggestion解析完毕

SuggestionCarWashing carWashing=new

SuggestionCarWashing();

carWashing=ParseCarWashing(ParseResult(string)); System.out.println(carWashing.toString());

SuggestionDressing dressing=new SuggestionDressing(); dressing=ParseDressing(ParseResult(string)); System.out.println(dressing.toString());

SuggestionFlu flu=new SuggestionFlu();

flu=ParseFlu(ParseResult(string));

System.out.println(flu.toString());

SuggestionSport sport=new SuggestionSport(); sport=ParseSport(ParseResult(string));

System.out.println(sport.toString());

SuggestionTravel travel=new SuggestionTravel(); travel=ParseTravel(ParseResult(string));

System.out.println(travel.toString());

SuggestionUv uv=new SuggestionUv();

uv=ParseUv(ParseResult(string));

System.out.println(uv.toString());

System.out.println(ParseUpdateTime(ParseResult(string))); }

//将原始的JSON数据解析之后返回（主要是提取result中的内容） public String ParseResult(String originalJSON)

{

JSONObject

resultsJSONObject=JSONObject.fromObject(originalJSON);

JSONArray

resultsJSONArray=resultsJSONObject.getJSONArray("results");

return resultsJSONArray.getJSONObject(0).toString(); }

//提取location中的内容，并且将提取出来的内容放到Location对象中并返回

public Location ParseLocation(String resultJSON)

{

Location location=new Location();

JSONObject

locationJSONObjectOriginal=JSONObject.fromObject(resultJSON); String

locationString=locationJSONObjectOriginal.getString("location");

后台转换JSON数据类型,前台解析JSON数据等等例子总结
在线解析json数据第三篇

后台转换JSON数据类型，前台解析JSON数据等等例子总结 JSON对象：

JSONObject obj = new JSONObject();

return obj.toJSONString();

前台解析： Success:function(data){

var result = data.result;

var message = data.message; }

json对象中有json对象的写法:

Objstr为一个JSONObject obj的String转换

private String getsuccess(String objstr,int number){

JSONObject obj = new JSONObject();

return obj.toJSONString();

}

前台解析：

Picjson为success返回的data

var result = picjson.result;

if (result==1) {

var objdata = picjson.obj;

var data = eval('(' + objdata + ')'); var num = picjson.number;

picurl = null;

showpiclist(data, num);

} else{

alert(picjson.message);

picurl = null;

}

list转成json对象

需要的包：

1.commons-lang.jar

2.commons-beanutils.jar

3.commons-collections.jar

4.commons-logging.jar

5.ezmorph.jar

6.json-lib-2.2.2-jdk15.jar ，

由于在struts2中没有自带的.ezmorph.jar ，一开始List对象列表转换成json数据格式的时候并不对还报错 List<ImageBean>

bean=newmainservice.getImageBeanbyNewid(newid); JSONArray

json=JSONArray.fromObject((Object)bean); System.out.println(json.toString());

response.getWriter().print(json.toString()); }catch(Exception e){e.printStackTrace();} 前台解析： $.ajax({

method:"post",

url:"/bs.cxhd/pub/newpiclist.action", data:{"newid":newid},

success:function(data){

var piclist=eval(data);

alert(piclist.length);

alert(piclist[0]["url"]);

error:function(data){} 因为时间有限，我就不贴那么多代码了，剩下的自己看看就懂额。毕设有需要的联系QQ2978077563
