推荐答案

这是一个浏览器问题，出于安全原因，您无法通过代码控制。

It's a browser issue and not something you can control via code for security reasons.

你最接近他们的位置而没有明确询问他们的位置数据是通过他们的IP地址 - 只有在家庭WiFi上才准确 - 3G / 4G IP地址不会给你任何准确的位置数据。



查看 Codehelper API [ ^ ] - 这是一个基于JS的库，事实上我在这里通过javascript问题回答某人的位置：根据IP地址查找用户位置无效 [< a href =http://www.codeproject.com/Answers/853635/find-user-loaction-based-on-ip-address-is-not-work#answer2target =_ blank> ^ ]



以下是它涉及的内容：

The closest you'd get to their location without explicitly asking for their location data is by their IP address - which will only be accurate if they are on a home WiFi - 3G/4G IP addresses will not give you any accurate location data.

Check out Codehelper API[^] - that is a JS based library and in-fact I answered someones location by javascript question here: find user location based on ip address is not working[^]

Here's what it involves:

<script src="http://www.codehelper.io/api/ips/?js"></script>
<script>
window.onload = function(){
    console.log(codehelper_ip);
};
</script>

返回JSON对象：

Which returns a JSON object:

{"IP":"149.215.142.9","ContinentCode":"EU","ContinentName":"Europe","CountryCode2":"GB","CountryCode3":"GBR","Country":"GB","CountryName":"United Kingdom","RegionName":"Unknown","CityName":"Unknown","CityLatitude":51.5,"CityLongitude":-0.13,"CountryLatitude":54,"CountryLongitude":-4.5,"LocalTimeZone":"Europe/London","REMOTE_ADDR":"149.215.142.9","HTTP_X_FORWARDED_FOR":"149.215.142.9","CallingCode":"44","Population":"61,113,205 (22)","AreaSqKm":"243,610 (80)","GDP_USD":"2.226 Trillion (7)","Capital":"London","Electrical":"230 V,50 Hz Type G","Languages":"English, Welsh (about 26% of the population of Wales), Scottish form of Gaelic (about 60,000 in Scotland)","Currency":"Pound Sterling (GBP)","Flag":"http://www.codehelper.io/api/ips/proips/flags/GB.jpg"}

我的建议是你可以使用它并仍然要求他们的纬度/长度 - 如果他们提供它然后很棒你得到一个更准确的位置 - 如果没有，你大致了解它们的位置。

My suggestion is that you could use this and still request their lat/long - if they provide it then great you get a more accurate location - if not, you get a general idea of where they are.
