二、地区Json格式

1、省级

ProJson.js

province = [{ "ID": , "NAME": "海南省", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "陕西省", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "北京市", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "天津市", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "河北省", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "山西省", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "内蒙古自治区", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "吉林省", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "黑龙江省", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "上海市", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "浙江省", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "安徽省", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "福建省", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "山东省", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "河南省", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "湖北省", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "广东省", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "广西壮族自治区", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "四川省", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "云南省", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "西藏自治区", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "甘肃省", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "宁夏回族自治区", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "新疆维吾尔自治区", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "辽宁省", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "江苏省", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "江西省", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "湖南省", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "贵州省", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "青海省", "PARENT_ID": , "DEEP":  }, { "ID": , "NAME": "重庆市", "PARENT_ID": , "DEEP":  }];

2、部分市级
