如何获取浏览器定位信息存储到浏览器缓存中？

  mounted() {
    // 获取地理位置
    var geolocation = new BMapGL.Geolocation()
    // 判断浏览器类型
    var ua = navigator.userAgent.toLowerCase()
    var isFirefox = ua.indexOf('firefox') !== -1
    var isChrome = ua.indexOf('chrome') !== -1 && ua.indexOf('safari') !== -1
    geolocation.getCurrentPosition(function(r) {
      if (this.getStatus() === BMAP_STATUS_SUCCESS) {
        const province = r.address.province
        let city = r.address.city
        const district = r.address.district
        const street = r.address.street
        // 处理火狐浏览器返回的地理位置信息格式
        if (isFirefox) {
          city = r.address.city
        }
        // 处理谷歌浏览器返回的地理位置信息格式
        if (isChrome) {
          if (city === '市辖区' || city === '县') {
            city = r.address.province + r.address.district
          }
        }
        console.log('=======', province)
        console.log('=======', city)
        console.log('=======', district)
        console.log('=======', street)
        alert(province + city + district + street)
        localStorage.setItem('location', province.trim() + ' ' + city.trim() + ' ' + district.trim() + ' ' + street.trim())
      }
    })
  },
