解析json并获取想要的值

Question

[
{
"class":"1",
"id":"1",
"stu":
[
{
"name":"zhang",
"age":"11"
},
{
"name":"wang",
"age":"12"
}
]
},

    {
        "class":"2",
            "id":"2",
            "stu":
            [
              {
                   "name":"ding",
                     "age":"19"
                },
                {
                   "name":"li",
                     "age":"15"
                }
            ]
     }
    .
    ."class":"3"
    ."class":"4"
 ]
 例如这个json,  其中class 3,4,5等等就不写了.我想遍历出所有class的id和
 单独列出每个class里stu的信息.
 请问各位大大该怎么在js里实现啊.
