vue中调用百度地图获取经纬度

项目中，需要实现获取当前位置的经纬度，或者搜索某个位置并获取经纬度信息，我使用的的是vue，地图使用的是百度地图。

默认自动获取当前位置经纬度

拖动小红标获取经纬度

关键词查询获取经纬度

前期准备

首先，我们需要取百度官方申请一个地图api秘钥，登录百度帐号进入后在应用管理，我的应用去申请即可。

申请好以后，我们打开vue项目中public文件下的index.html文件，拼接百度AK值并引入

如上所示，红色区域为AK值，自行拼接自己的，可以设置权限为公开或者针对网址白名单。

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

我使用了elementui的弹窗，输入框，提示，如果你没使用elementui，记得更换哦！
