Mapbox获取当前位置

mapbox

Julia · 技术社区 · 6 年前

我正在从地图箱中获取当前位置。这是我在他们的地图箱网站上找到的一个例子,当我点击“找到我”时,它工作得很好。但是,当我在服务器上复制代码时,它似乎不起作用。当我用服务器上的代码单击“查找我”时,会出现“找不到位置”错误。谢谢。

这个密码对我来说很管用。

当我用服务器上的代码单击“查找我”时,我会得到这个错误“找不到位置。”

这可能是因为你不使用 https 以及一个不支持地理位置不安全的来源(如Chrome)或你阻止了gelocation的浏览器。

编辑:

要从注释中回答您的问题,下面是用于在页面加载时查找位置的经过调整的代码,而不是单击“查找我”按钮:
