Vue2接入高德地图API实现搜索定位和点击获取经纬度及地址功能

news 2024/11/14 13:53:27

一、申请密钥

二、安装element-ui

三、安装高德地图依赖

四、完整代码

五、运行截图

一、申请密钥

登录高德开放平台，点击我的应用，先添加新应用，然后再添加Key。

如图所示填写对应的信息，系统就会自动生成。

二、安装element-ui

没安装的看官方文档：Element - The world's most popular Vue UI framework

三、安装高德地图依赖

npm i @amap/amap-jsapi-loader --save

四、完整代码

把刚才申请好的安全密钥和Key替换进去。

完整代码：
