地理定位不适用于Windows 7 / XP上的Safari 5.x [英] Geolocation not workin on Safari 5.x on Windows 7/XP

问题描述

我正在开发一款使用W3C标准地理定位API的应用程序，但是我不能在我的Windows 7和XP PC上使用它在Safari上工作。它可以在我的iPad和iPhone上正常工作。它也适用于Chrome（5,6,7和Canary版本）和Firefox（3.6）。我没有Mac，所以我无法测试它。 IE不支持地理位置，所以这也包括在内。

我创建了一个精简版，我将它托管在Google Apps引擎上，以便您看看代码： http://html5-geolocator.appspot.com/ 。所有（简化的）javascript都在html中，所以你应该能够右键单击并调试/查看源代码。

这几乎是对示例的直接转换在 Google地图API DevGuide 上。有趣的是，Google托管的示例在Windows 7上的Safari 5.0.x中也不起作用（但它们可以在所有其他平台上正常工作，与我的应用程序相同），例如 http://code.google.com/apis/maps/documentation/javascript/examples/map-geolocation .html 显示与我的APP完全相同的问题，没有显示地图，网页只是保持灰色。

通过一些调试（警告（我在这里）:-)似乎在Safari中，它确实执行了navigator.geolocation.getCurrentPosition（myCallback），但它似乎永远不会到达myCallback ......就好像它从不从getCurrentPosition返回一样。我还看到，如果我在一夜之间离开浏览器窗口，当我在早上回到浏览器窗口时，警报和地图出现（尽管并非总是）。我也尝试添加一个errorCallback navigator.geolocation.getCurrentPosition（myCallback，errorCallback），但它也从来没有执行过，再次表明它永远不会从getCurrentPosition调用返回。

任何人都可以想法为什么发生这种情况？

编辑：
只做了一些更多的测试，我添加了超时选项（navigator.geolocation.getCurrentPosition（myCallback，errorCallback，{timeout ：5000}）;），并且事实上它总是超时，无论我设置了多高，所以它永远不会从Google地理位置服务返回，但为什么???

解决方案

请尝试开启您的wi-fi。看来，Safari依靠Wi-Fi连接工作。
我遇到了完全相同的问题，打开了我的Wi-Fi连接并完美工作。

我现在正在研究如何检测这个问题 - 将会更新，如果我找到解决方案

I am working on an app that uses the W3C standard geolocation API but I cannot for the life of me get it to work on Safari on my Windows 7 and XP PC. It works fine on my iPad and my iPhone. It also works perfect on Chrome (5, 6, 7 and the Canary build) and on Firefox (3.6). I don't have a Mac so I can't test it on that. IE doesn't support geolocation yet so that's covered too.

I created a stripped down version and I am hosting it on the Google Apps Engine so you can have a look at the code: http://html5-geolocator.appspot.com/ . All the (simplified) javascript is in the html so you should be able to right-click and debug/view source.

It is pretty much a straight conversion of the examples on the Google Map API DevGuide. Interestingly enough, the examples that Google is hosting are also NOT WORKING in Safari 5.0.x on Windows 7 (but they work fine on all those other platforms, same as my app), for example http://code.google.com/apis/maps/documentation/javascript/examples/map-geolocation.html exhibits exactly the same issue as my APP, no map appears, the webpage just stays grey.

Through some debugging (alert("I am here") :-) it seems that in Safari, it does execute navigator.geolocation.getCurrentPosition(myCallback), but it never seems to reach myCallback ... as if it never returns from getCurrentPosition. I have also seen that if I leave the browser window open overnight, when I get back to it in the morning the alert and map have appeared (though not always). I also tried added a errorCallback navigator.geolocation.getCurrentPosition(myCallback, errorCallback) but it also never executes that, again suggesting it never returns from the getCurrentPosition call.

Anybody any ideas why this happens?

EDIT: Just did some more testing, I added the timeout option (navigator.geolocation.getCurrentPosition(myCallback, errorCallback, {timeout: 5000});) , and indeed it it timing out all the time, no matter how high I set it so it is never returning from the Google geolocation service, but why???

解决方案

Try turning on your wi-fi. It appears that Safari relies on the wi-fi connection to work. I was having exactly the same issues, turned my wi-fi connection on and it work perfectly.

I'm now looking at how to detect this - will update if I find a solution
