前端通过高德地图实现定位,拖拽选址,搜索选址,搜索记录,城市切换【推荐】

已经结合高德地图api实现了定位,用户拖拽选址,搜索选址,搜索记录,城市切换等功能，案例已经非常完善，注意定位在pc浏览器上是有偏差，需要在手机里定位才能精准到5米，文末会放上案例地址，clone下来可以本地调试和使用。预览地址：点我打开，建议手机上打开

高德api申请

这个不多说，需要在高德申请个key，使用的高德2.0的sdk

布局

说明：这里使用的vant的组件，需要引入vant，主要就是用的他的css风格，

{{ city || "定位中..." }} 取消附近位置 {{ item.name }} {{ item.address }} 历史搜索 {{ item }} {{ item.name }} {{ item.district }}{{ item.address }} 下面的loadJs封装 // 异步加载css文件 export const includeCss = function (filename) { var head = document.getElementsByTagName("head")[0];
