高德地图使用vue-amap开发 页面刷新地图空白

使用vue-amap地图开发的时候，刷新页面地图就不显示了。因为刷新的时候AMapUI没有加载出来导致地图显示空白。

使用remoteLoad 来解决

// remoteLoad.js
export default function remoteLoad(url, hasCallback) {
  return createScript(url)
  /**
   * 创建script
   * @param url
   * @returns {Promise}
   */
  function createScript(url) {
    var scriptElement = document.createElement('script')
    document.body.appendChild(scriptElement)
    var promise = new Promise((resolve, reject) => {
      scriptElement.addEventListener('load', e => {
        removeScript(scriptElement)
        if (!hasCallback) {
          resolve(e)
        }
      }, false)
 
      scriptElement.addEventListener('error', e => {
        removeScript(scriptElement)
        reject(e)
      }, false)
 
      if (hasCallback) {
        window.____callback____ = function() {
          resolve()
          window.____callback____ = null
        }
      }
    })
 
    if (hasCallback) {
      url += '&callback=____callback____'
    }
 
    scriptElement.src = url
 
    return promise
  }
 
  /**
   * 移除script标签
   * @param scriptElement script dom
   */
  function removeScript(scriptElement) {
    document.body.removeChild(scriptElement)
  }
}
