4使用

const request = require('../../assets/js/request.js')
const api = require('../../assets/js/api.js')

// 请求城市数据

  getCity: function() {
    let that = this
    request._get(api.cityList).then((res) => {
      console.log(res)
      //定义全局变量cityList 存储城市数据
      cityList = res.data
      let arr = []
      res.data.forEach((item) => {
        arr.push(item.name)
      })
      that.setData({
        province: arr
      })
// 设置默认选中省份
      that.initChooseCity()
    })
  },
