我有一个商店定位器工作得很好，但我想删除地图功能，所以我可以只使用地理定位服务，运行json文件，找到最近的商店 - 一切都在那里，我只需要一些帮助剥离出来地图/标记材料
有人能帮助解决这个问题吗？代码从以下位置开始：//使用jQuery创建地图
我假设大部分都可以删除但是需要为列表数据保留循环（我只想显示1是最接近而不是列表）

使用地理编码而不显示地图是针对Googles TOS
答案 1 :(得分：0)
所有的地图内容都是[除了实用程序函数listClick（），从...开始 //使用jQuery行创建地图，并在函数listClick之前结束 如果您注释掉该部分，则不会创建地图 只记得那个地图div仍然是可见的[没有mapo里面，但它仍然存在，所以考虑评论那个HTML标签
