使用vue+原生高德地图API+element-ui绘制后端返回的经纬度轨迹
在公司想要做这个需求之前,我翻阅过很多资料,最终在高德地图原生API和vue-amap上还是选择了高德地图原生API,至于原因嘛,当然是因为官网有相关实例可参考,并且vue-amap还是要熟悉原生高德地图API,所以不如直接用高德地图原生API。在这段时间里也是绕过一段远路,最终完美完成了所达到的效果,话不多说,分享一下自己踏过的坑,也希望有大佬给指点一二。
一、引入高德地图
1、在项目入口文件index.html引入高德地图
//引入高德地图
<script type="text/javascript" src="https://webapi.amap.com/maps?v=1.4.15&key=你的高德key"></script>
2、在vue.config.js中引入(若项目vue-cli版本低于3.0则在webpack.base.conf.js中引入,不同的项目可能有不一样的文件)
module.exports = {
configureWebpack: {
externals: {
'AMap': 'AMap' // 高德地图配置
}
}
}
二、相关代码
<template>
<div class="app-container">
...
<div id="carMap" style="width:100%;height:100%" />
</div>
</template>
<script>
