前言
小程序实现新功能，在地图中选取位置添加标记，并在地图中呈现添加的标记，（呈现的是根据当前屏幕范围内的标记），并对标记进行分享，删除，编辑，导航，并从分享标记点位置打开页面的时候在呈现该标记的信息详情，
部分代码解释
javascript">scale：地图缩放级别
markers：标记点
callouttap：标记点点击事件
markertap：markers内容的点击事件，就是自定义内容的点击事件
regionchange：推拽事件
regionchange - begin ：拖拽开始事件
regionchange - end：拖拽结束事件
this.mapContext = uni.createMapContext("map", this); // 创建地图上下文
that.mapContext.getCenterLocation： 获取中心点位置
that.mapContext.getRegion ： 获取后获取对角坐标
that.mapContext.getScale ： 获取缩放级别更多更详细地图上下文接口点击这里（uniapp官网，进去就是地图上下文相关）
uni.chooseLocation 和 uni.getLocation 使用的时候需要先声明
部分功能图片预览
声明：图片中内容为随机添加，内容也是胡乱写的
拖动地图，位置也会及时更新，选取添加的标记点位置
地图首页
添加修改标记页面和搜索页面就没必要放上来了，都是一些基础的样式和添加逻辑，根据个人情况写就行了，主要就是添加标记，（添加页面传递参数就是进度和纬度，有重要这两个数据就可以了），bijiaoInfos，就是分享和搜索页面传递过来的，根据id请求详情，拿到经纬度，把这个坐标定为中心点，再让地图重新加载，然后在自动弹出这个id的详情弹窗，就是示例的第二张图，通过搜索和分享进来看到的就是这个页面。
