Question

这样的复杂Json数据怎么样解析呢，向大神求助要，最好能贴下代码，谢谢了！

{"floors":[{"fid":1,"fname":"主层","room":[{"dev":[{"did":1, "devid":1,"cmd":[{"cid":400,"cname":"电视"},{"cid":401,"cname":"电视"}],"dname":"电视","tid":3},{"did":2, "devid":2,"cmd":[{"cid":402,"cname":"冰箱"},{"cid":403,"cname":"冰箱"}],"dname":"冰箱","tid":3},{"did":3, "devid":3,"cmd":[{"cid":404,"cname":"电暖"},{"cid":405,"cname":"电暖"}],"dname":"电暖","tid":3},{"did":4, "devid":4,"cmd":[{"cid":406,"cname":"风扇"},{"cid":407,"cname":"风扇"}],"dname":"风扇","tid":3},{"did":5, "devid":5,"cmd":[{"cid":408,"cname":"音响"},{"cid":409,"cname":"音响"}],"dname":"音响","tid":3}],"rname":"玄关","rid":1},{"dev":[],"rname":"客厅","rid":2}]},{"fid":2,"fname":"复层","room":[{"dev":[],"rname":"客厅","rid":1},{"dev":[],"rname":"偏厅","rid":2},{"dev":[],"rname":"娱乐室","rid":3}]},{"fid":3,"fname":"厨卫","room":[{"dev":[],"rname":"客厅","rid":1},{"dev":[],"rname":"书房","rid":2},{"dev":[],"rname":"套房","rid":3},{"dev":[],"rname":"主卧","rid":4}]}]}

要求能拿到里面所有"cid"的值。

Answer 1

什么叫json解析？这个跟json有一毛钱的关系？
你这是ajax校验（验证原密码是否正确）+本地校验（难密码是否一致，是否满足密码的规则）吧。

Answer 2

var DATA='[{"data":{"x":{"precision":2,"subtype":"","type":"array","unit":" ","value":[-23.93000030517578]},"y":{"precision":2,"subtype":"","type":"array","unit":" ","value":[-8.890000343322754]}},"devtype":"DAIS","msg":"multidata","netid":1128,"nodid":2501,"nvsid":2001181,"version":2}]';
eval(DATA);
