帮我看下这个JSON。

<script type="text/javascript">

        $(document).ready(function () {

            var cid = 20;

            var txt;

            $.ajax({

                type: "POST",

                contentType: "application/json",

                url: "GetTaoBaoItemCats.asmx/GetItemCats",

                data: "{cid:" + cid + "}",

                dataType: 'json',

                error: function (result, status) { //如果没有上面的捕获出错会执行这里的回调函数

                    if (status == 'error') {

                        alert(status);

                    }

                },



                success: function (result) {

                    var data = result.d;



                    alert(data);



                     });

                                    }

            });



        });

    

    </script>

这样我可以弹出数据如下。。
{"itemcats_get_response":{"item_cats":{"item_cat":[{"cid":50017905,"is_parent":false,"name":"游戏掌机\/PSP\/NDSL","parent_cid":20},{"cid":50017906,"is_parent":false,"name":"家用游戏机\/PS3\/Wii\/XBOX","parent_cid":20},{"cid":50012068,"is_parent":false,"name":"游戏手柄","parent_cid":20},{"cid":50012834,"is_parent":true,"name":"游戏软件","parent_cid":20},{"cid":50012079,"is_parent":false,"name":"方向盘","parent_cid":20},{"cid":50012080,"is_parent":false,"name":"摇杆","parent_cid":20},{"cid":50012160,"is_parent":true,"name":"PSP专用配件","parent_cid":20},{"cid":50012161,"is_parent":true,"name":"WII专用配件\/周边","parent_cid":20},{"cid":50012162,"is_parent":true,"name":"PS2\/PS3专用配件（包含PS1)","parent_cid":20},{"cid":50012163,"is_parent":true,"name":"NDSI\/NDSL专用配件","parent_cid":20},{"cid":50018082,"is_parent":true,"name":"XBOX专用配件","parent_cid":20},{"cid":50018224,"is_parent":true,"name":"世嘉 DC\/MD\/SS\/SEGA 专用配件","parent_cid":20},{"cid":50018225,"is_parent":true,"name":"任天堂NGC\/FC\/N64\/SFC 专用配件","parent_cid":20},{"cid":50018230,"is_parent":true,"name":"任天堂掌机配件","parent_cid":20}]}}}

我现在是要读取这些个数据，循环出业NAME和CID

var json = {"itemcats_get_response":{"item_cats":{"item_cat":[{"cid":50017905,"is_parent":false,"name":"游戏掌机\/PSP\/NDSL","parent_cid":20},{"cid":50017906,"is_parent":false,"name":"家用游戏机\/PS3\/Wii\/XBOX","parent_cid":20},{"cid":50012068,"is_parent":false,"name":"游戏手柄","parent_cid":20},{"cid":50012834,"is_parent":true,"name":"游戏软件","parent_cid":20},{"cid":50012079,"is_parent":false,"name":"方向盘","parent_cid":20},{"cid":50012080,"is_parent":false,"name":"摇杆","parent_cid":20},{"cid":50012160,"is_parent":true,"name":"PSP专用配件","parent_cid":20},{"cid":50012161,"is_parent":true,"name":"WII专用配件\/周边","parent_cid":20},{"cid":50012162,"is_parent":true,"name":"PS2\/PS3专用配件（包含PS1)","parent_cid":20},{"cid":50012163,"is_parent":true,"name":"NDSI\/NDSL专用配件","parent_cid":20},{"cid":50018082,"is_parent":true,"name":"XBOX专用配件","parent_cid":20},{"cid":50018224,"is_parent":true,"name":"世嘉 DC\/MD\/SS\/SEGA 专用配件","parent_cid":20},{"cid":50018225,"is_parent":true,"name":"任天堂NGC\/FC\/N64\/SFC 专用配件","parent_cid":20},{"cid":50018230,"is_parent":true,"name":"任天堂掌机配件","parent_cid":20}]}}};



      var item_cats = json.itemcats_get_response.item_cats.item_cat; 

      for(var i = 0 ; i < item_cats.length ; i++ ){

        alert(item_cats[i].cid + "  --  " + item_cats[i].name); 

      }
