这样一个JSON字符串如何解析

这样一个JSON字符串怎么解析？

CSS code

[{"prolist":[{"actors":"","addedtime":"","canrecommend":false,"director":"","isadvertisement":false,"keywords":"","name":"","programid":"Umai:SERI/661338@","programlength":0,"seriesid":"true","tags":"","typeid":3}, {"actors":"","addedtime":"","canrecommend":false,"director":"","isadvertisement":false,"keywords":"","name":"","programid":"Umai:SERI/499229@","programlength":0,"seriesid":"true","tags":"","typeid":3}, {"actors":"","addedtime":"","canrecommend":false,"director":"","isadvertisement":false,"keywords":"","name":"","programid":"Umai:SERI/662417@","programlength":0,"seriesid":"true","tags":"","typeid":3}],"programtype":"1","preference":"言情剧|偶像剧","total_results":"10"}]

这个JSON是这样的，本身是以Map在后台格式化的，然后里面第一个key是prolist值是List
剩下的programtype、preference、total_results都是字符串，
我现在要在前台用JS或jQuery将prolist里的值循环显示出来，后面那3个字符串也单独显示出来
可是我怎么也取不到值

JScript code

$.getJSON("ppshow", function(data){    $.each(data, function(i, item){        alert(i);    });});

我这样写只给弹了个0出来了，难道还是Map不能这样取么？


[解决办法]
本来就只有一条记录啊

JScript code

var json = [{"prolist":[{"actors":"","addedtime":"","canrecommend":false,"director":"","isadvertisement":false,"keywords":"","name":"","programid":"Umai:SERI/661338@","programlength":0,"seriesid":"true","tags":"","typeid":3}, {"actors":"","addedtime":"","canrecommend":false,"director":"","isadvertisement":false,"keywords":"","name":"","programid":"Umai:SERI/499229@","programlength":0,"seriesid":"true","tags":"","typeid":3}, {"actors":"","addedtime":"","canrecommend":false,"director":"","isadvertisement":false,"keywords":"","name":"","programid":"Umai:SERI/662417@","programlength":0,"seriesid":"true","tags":"","typeid":3}],"programtype":"1","preference":"言情剧|偶像剧","total_results":"10"}];alert( json.length )for( var x in json[0] ){    alert( json[0][x] )}
[解决办法]
var json = [{"prolist":
[{"actors":"","addedtime":"","canrecommend":false,"director":"","isadvertisement":false,"keywords":"","name":"","programid":"Umai:SERI/661338@","programlength":0,"seriesid":"true","tags":"","typeid":3}, 
 
  {"actors":"","addedtime":"","canrecommend":false,"director":"","isadvertisement":false,"keywords":"","name":"","programid":"Umai:SERI/499229@","programlength":0,"seriesid":"true","tags":"","typeid":3},
  {"actors":"","addedtime":"","canrecommend":false,"director":"","isadvertisement":false,"keywords":"","name":"","programid":"Umai:SERI/662417@","programlength":0,"seriesid":"true","tags":"","typeid":3}],
"programtype":"1",
"preference":"言情剧|偶像剧",
"total_results":"10"}];



获取时用这json[0].prolist[0].canrecommend,就能获取到第一个actors里面的canrecommend对应的值了。
已经帮你测试过了。
具体要哪个对象和逻辑处理就你自己看着办了，解析数据用findbug看下就很快能解析了
