批改json格式

修改json格式
使用js对json进行操作，{"AreaName":"江苏省","AreaCode":"320000"},{"AreaName":"南京市","AreaCode":"320100"},{"AreaName":"市辖区","AreaCode":"320101"},{"AreaName":"玄武区","AreaCode":"320102"},{"AreaName":"白下区","AreaCode":"320103"},{"AreaName":"秦淮区","AreaCode":"320104"},{"AreaName":"建邺区","AreaCode":"320105"},{"AreaName":"鼓楼区","AreaCode":"320106"},{"AreaName":"下关区","AreaCode":"320107"},{"AreaName":"浦口区","AreaCode":"320111"},{"AreaName":"栖霞区","AreaCode":"320113"},{"AreaName":"雨花台区","AreaCode":"320114"},{"AreaName":"江宁区","AreaCode":"320115"},{"AreaName":"六合区","AreaCode":"320116"},{"AreaName":"溧水县","AreaCode":"320124"},{"AreaName":"高淳县","AreaCode":"320125"}这种样式的数据转换成

{"AreaName":"江苏省","AreaCode":"320000","cityList":[{"AreaName":"南京市","AreaCode":"320100","areaList":[{"AreaName":"市辖区","AreaCode":"320101"},{"AreaName":"玄武区","AreaCode":"320102"},{"AreaName":"白下区","AreaCode":"320103"},{"AreaName":"秦淮区","AreaCode":"320104"},{"AreaName":"建邺区","AreaCode":"320105"},{"AreaName":"鼓楼区","AreaCode":"320106"},{"AreaName":"下关区","AreaCode":"320107"},{"AreaName":"浦口区","AreaCode":"320111"},{"AreaName":"栖霞区","AreaCode":"320113"},{"AreaName":"雨花台区","AreaCode":"320114"},{"AreaName":"江宁区","AreaCode":"320115"},{"AreaName":"六合区","AreaCode":"320116"},{"AreaName":"溧水县","AreaCode":"320124"},{"AreaName":"高淳县","AreaCode":"320125"}]}]}
这种形式的，用js怎么实现？？大神求帮助 JSON JavaScript
[解决办法]

写的有点恶心，如果有问题我再优化一下。


var citys = [
    {"AreaName":"江苏省","AreaCode":"320000"},
    {"AreaName":"南京市","AreaCode":"320100"},
    {"AreaName":"市辖区","AreaCode":"320101"},

];
function fn(data , first , second , level){
    var result = [] , temp , startIndex=0;
    if(!level){
        second = '0000';
        level = 1;
        startIndex = 2;
    }else{
        startIndex = level*2;
    }
    for(var i in data){     
        if(data[i].AreaCode.indexOf(second)==startIndex){
            temp = data[i];            
            temp['cityList'] = fn(data , data[i].AreaCode.substring(0,level*2) , second.substring(startIndex) , level+1);
            result.push(temp);
        }else if(!second&&data[i].AreaCode.indexOf('00')==-1&&!data[i].AreaCode.indexOf(first)){            
            result.push(data[i]);
        }
    }
    return result;
}
console.log(fn(citys));

代码还有点问题，修改了下。
