html5 – 谷歌地图Javascript GeoLocation

注意：下面引用的html的原始来源是 http://www.w3schools.com/html/tryit.asp?filename=tryhtml5_geolocation_map和 Google Maps Javascript V3 geolocation – cannot access initialLocation variable unless alerted

我收集了三个不同版本的地理位置示例.一切都在Firefox中正常工作.无法在Chrome中使用.我已将Chrome权限设置为允许所有网站使用我的位置,但仍然没有成功.它必须是Chrome设置,但不是显而易见的设置：设置/显示高级设置/隐私/内容设置/位置/允许所有网站跟踪我的实际位置.

在Firefox中,我在提示共享位置后看到我当前的位置.

在Chrome中,我收到用户拒绝地理定位的请求或
错误：Geolocation服务失败,具体取决于html.

鉴于这适用于Firefox而不是Chrome,我认为它必须是Chrome设置,但我只是不知道我能做什么比允许所有网站跟踪我的物理位置更宽松.

以下是三个HTML5文件：

解决方法

Chrome和Safari(webkit浏览器)不允许Geolocation API用于文件系统中的文件.

只需创建一个Web应用程序并尝试使用localhost访问它

http://localhost/geoGoogle.html

html5 – 谷歌地图Javascript GeoLocation – 不适用于Chrome
