如何使用$.each（）遍历下面Json数据

json={"adserver":"HNAS","adconfig":[{"adid":"1","starttime":"0.00","adtype":"pre-roll","adurl":" http://","adtrick":"false"}
{"adid":"2","starttime":"1.00","adtype":"pre-roll","adurl":" http://","adtrick":"false"}
{"adid":"3","starttime":"2.00","adtype":"pre-roll","adurl":" http://","adtrick":"false"}
]}
少几个逗号 补上
json={"adserver":"HNAS","adconfig":[
{"adid":"1","starttime":"0.00","adtype":"pre-roll","adurl":" http://","adtrick":"false"},
{"adid":"2","starttime":"1.00","adtype":"pre-roll","adurl":" http://","adtrick":"false"},
{"adid":"3","starttime":"2.00","adtype":"pre-roll","adurl":" http://","adtrick":"false"},
]}

这个格式是不能用$.each（）的，因为它不是一个数组，这个json的字符串就是一个json对象，不是数组，你可以先把对象中的属性取出来，再用$.each循环第二个属性：
var adserver = json.adserver;
var adconfig = json.adconfig;
$(adconfig).each(function(){
var temp = $(this);//这里是把数组里的每个对象取出来
alert(temp.adid);
alert(temp.adurl);
});
