服务器返回的JSON："resp":[{"no":"01301000","name":"\u6c34\u679c","level":"1","num":"0","up":"0"},{"no":"01301100","name":"\u767d\u83dc\u7c7b","level":"2","num":"0","up":"0"},{"no":"01301103","name":"\u4e4c\u584c\u83dc","level":"3","num":"0","up":"0"}.....]
level:123表示，省市区
name:为名字（四川省，成都市，锦江区）
数组的排列顺序为：level 123333323333323333312333333323333....
我想实现效果是，点击四川省，会显示成都市，广安市..，再点击成都市，会显示高新区，青羊区.
搞了几天了，保存下来，冰天雪地全裸跪求解决方案！！！
搞了几天，没保存下来
你这数据连个上下级关系都没有，怎么知道那个市属于哪个省
既然知道关系了。先读取level就知道它是什么行政级别，然后v把对应数据都列出来。
加个父级id。点击四川知道他的id查市的时候就看谁的父级id是他就查出来了。
