应用
const utils = require('../utils')【留神，重庆/北京/上海/天津,4个为直辖市，不须要加省市】const address = utils.formattAddress('重庆重庆市梁平区和林镇三xxx')console.log(address) // { province: '重庆', city: '重庆市', county: '梁平区', village: '和林镇三xxx' }【留神，有2个区，只有一个区就行】const address = utils.formattAddress('广西壮族自治区南宁市良庆区金象三区五象路xxx')console.log(address) // { province: '广西壮族自治区', city: '南宁市', county: '良庆区', village: '金象三区五象路xxx' }
