传递给geolocation . getcurrentposition()的第二个参数是要处理任何地理位置错误的函数。错误处理函数本身接收一个PositionError对象，其中包含关于地理定位尝试失败原因的详细信息。我建议输出错误到控制台，如果你有任何问题:

var positionOptions = { timeout: 10000 };
navigator.geolocation.getCurrentPosition(updateLocation, errorHandler, positionOptions);
function updateLocation(position) {
  // The geolocation succeeded, and the position is available
}
function errorHandler(positionError) {
  if (window.console) {
    console.log(positionError);
  }
}

Doing this in my code revealed the message "Network location provider at 'https://www.googleapis.com/' : Returned error code 400". Turns out Google Chrome uses the Google APIs to get a location on devices that don't have GPS built in (for example, most desktop computers). Google returns an approximate latitude/longitude based on the user's IP address. However, in developer builds of Chrome (such as Chromium on Ubuntu) there is no API access key included in the browser build. This causes the API request to fail silently. See Chromium Issue 179686: Geolocation giving 403 error for details.

对于开发iPhone应用程序的人来说……

如果你的代码在ios9 +的UIWebView中运行，那么你必须在应用的plist中设置NSLocationWhenInUseUsageDescription。

如果你不设置它，那么getCurrentPosition将永远不会回调，用户也永远不会被提示。

我终于找到了一个工作版本的firefox, chrome和默认导航器在android(仅4.2测试):

function getGeoLocation() {
        var options = null;
        if (navigator.geolocation) {
            if (browserChrome) //set this var looking for Chrome un user-agent header
                options={enableHighAccuracy: false, maximumAge: 15000, timeout: 30000};
            else
                options={maximumAge:Infinity, timeout:0};
            navigator.geolocation.getCurrentPosition(getGeoLocationCallback,
                    getGeoLocationErrorCallback,
                   options);
        }
    }

这对我来说每次都管用:

navigator.geolocation.getCurrentPosition(getCoor, errorCoor, {maximumAge:60000, timeout:5000, enableHighAccuracy:true});

虽然它不是很准确。有趣的是，在同一台设备上，如果我运行这个程序，它会把我拖走大约100米(每次)，但如果我去谷歌的地图，它会准确地找到我的位置。因此，尽管我认为enableHighAccuracy: true有助于它始终如一地工作，但它似乎并没有使它更准确……

我发现，这种方法行不通

navigator.geolocation.getCurrentPosition(function() {...}, function(err) {...}, {});

But

这种方法非常有效

function storeCoordinates(position) {
    console.log(position.coords.latitude, position.coords.longitude);
}    

function errorHandler() {...}

navigator.geolocation.getCurrentPosition(storeCoordinates, errorHandler, { enableHighAccuracy: true, timeout: 20000, maximumAge: 0 });
