@param province {[String]} default:false 
    默认的省份(省级市),未传入则为“请选择”

@param city {[String]} default:false 
    默认的城市(市级区),未传入则为“请选择”

@param error {[Function]} default:false 
    出错时的处理函数,参数为错误说明,默认直接throw

  • missing argument: province: 初始化城市select的option时缺少对应的省份参数
  • illegal province: 所选省份不在省份数据中
