專案中，需要實現獲取當前位置的經緯度，或者搜尋某個位置並獲取經緯度資訊，我使用的的是，地圖使用的是百度地圖。

預設自動獲取當前位置經緯度

拖動小紅標 獲取經緯度

關鍵詞 查詢獲取經緯度

前期準備

首先，我們需要取百度官方申請一個地圖api祕鑰，https://lbsyun.baidu.com/apiconsole/key進入後在應用管理，我的應用去申請即可。

申請好以後，我們開啟vue專案中public檔案下的index.html檔案，拼接百度AK值並引入

<script type="text/" src="http://api.map.baidu.com/api?v=2.0&ak=WFKACU6v7aiUdnkgtMCqdWBZC68KpUXv"></script>  

如上所示，紅色區域為AK值，自行拼接自己的，可以設定許可權為公開或者針對網址白名單。

<script type="text/script" src="http://api.map.baidu.com/api?v=2.0&ak=WFKACU6v7aiUdnkgtMCqdWBZC68KpUXv"></script>

我使用了elementui的彈窗，輸入框，提示，如果你沒使用elementui，記得更換哦！
