如何使用$.each（）遍历下面Json数据

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 = jsonadserver;
var adconfig = jsonadconfig;
$(adconfig)each(function(){
var temp = $(this);//这里是把数组里的每个对象取出来
alert(tempadid);
alert(tempadurl);
});

var a=[{"list":[{"count":0,"createTime":"2008-01-25 00:00:00","createUserDept":"","createUserDeptId":"","createUserId":"","createUserName":"","deleteFlag":"0","introduction":"","month":"","pagerSize":0,"periodicalId":"","periodicalName":"admin","periodicalType":"","publishDate":null,"status":"0","updateUserDept":"","updateUserDeptId":"","updateUserId":"","updateUserName":"","year":""},{"count":0,"createTime":"2008-01-25 00:00:00","createUserDept":"","createUserDeptId":"","createUserId":"","createUserName":"","deleteFlag":"0","introduction":"","month":"","pagerSize":0,"periodicalId":"","periodicalName":"admin","periodicalType":"","publishDate":null,"status":"0","updateUserDept":"","updateUserDeptId":"","updateUserId":"","updateUserName":"","year":""}],"pageString":""}]
var list=a[0]list;
for(i=0;i<listlength;i++){
alert(list[i]count);
alert(list[i]createTime);



}
当数组处理，只是成员为对象

var obj = {};
for(var k in obj) {
    //遍历对象，k即为key，obj[k]为当前k对应的值
    consolelog(obj[k]);
}

var typeArr = new Array();
for(var i = 0;i<infoListlength;i++)
{
    typeArrpush(infoList[i]type)   //获取到type的值
    for(var j = 0;j<infoList[i]typeListlength;j++)
    {
        var info = infoList[i]typeList[j];
        alert(infoID);
        alert(infostartDate);
        alert(infoendDate);
        alert(infoadultNum);
        alert(infochildrenNUm);
    }
}

这样就遍历出了所有的数据了
