UC知道这样的json用Jquery该怎么解析？

通过Jquery的$.Ajax方法得到一个Json，将这个对象输出到屏幕上为：
{ "Head ":
[
{
"name ": "aaa ",
"sex ": "男 ",
"age ": "15 ",
"date ": "2009-6-29 23:00:44 "
},
{
"name ": "bbb ",
"sex ": "男 ",
"age ": "21 ",
"date ": "2009-6-29 18:24:53 "
},
{
"name ": "ccc ",
"sex ": "男 ",
"age ": "40 ",
"date ": "2009-6-29 18:18:12 "
{ "Head ":
[
{
"name ": "aaa ",
"sex ": "男 ",
"age ": "15 ",
"date ": "2009-6-29 23:00:44 "
},
{
"name ": "bbb ",
"sex ": "男 ",
"age ": "21 ",
"date ": "2009-6-29 18:24:53 "
},
{
"name ": "ccc ",
"sex ": "男 ",
"age ": "40 ",
"date ": "2009-6-29 18:18:12 "
eval('var json='+jsonstr); // jsonstr就是上面的Json字符串
然后就可以这么用了:
alert(json['Head'][1]['name']); // 打印出 'bbb'
如果用$.getJSON,第一句可以省了,直接像第二句那么用
你直接用getJson函数不就行了！
它怎么解析是它的事情
二楼：在过几年(或者几个月）你的代码就会出错了
解析JSON很简单啊，firefox 3.5里有内置的JSON对象，不过其他浏览器里就没那么好了
还要自己去json.org下载json2.js
然后解析用JSON.parse方法就行了
