Question

我想获取用户当前位置的用户纬度和经度值。我的asp.net Web应用程序运行在 HTTP 协议上，并且根据Google的开发人员指南，该应用程序必须运行在HTTPS协议上才能使用HTML5 GeoLocation Service。我以某种方式找到了https://stackoverflow.com/a/39367531/7057220这个解决方案，并且尝试了这个

 <script type="text/javascript">
        $(document).ready(function () {
            debugger;
            var apiGeolocationSuccess = function (position) {
                alert("API geolocation success!\n\nlat = " + position.coords.latitude + "\nlng = " + position.coords.longitude);
            };
            var tryAPIGeolocation = function () {
                debugger;
                jQuery.post("https://www.googleapis.com/geolocation/v1/geolocate?key=MyAPIKey", function (success) {
                    apiGeolocationSuccess({ coords: { latitude: success.location.lat, longitude: success.location.lng } });
                })
              .fail(function (err) {
                  alert("API Geolocation error! \n\n" + err);
              });
            };

            var browserGeolocationSuccess = function (position) {
                debugger;
                alert("Browser geolocation success!\n\nlat = " + position.coords.latitude + "\nlng = " + position.coords.longitude);
            };

            var browserGeolocationFail = function (error) {
                switch (error.code) {
                    case error.TIMEOUT:
                        alert("Browser geolocation error !\n\nTimeout.");
                        break;
                    case error.PERMISSION_DENIED:
                        if (error.message.indexOf("Only secure origins are allowed") == 0) {
                            tryAPIGeolocation();
                        }
                        break;
                    case error.POSITION_UNAVAILABLE:
                        alert("Browser geolocation error !\n\nPosition unavailable.");
                        break;
                }
            };
            var tryGeolocation = function () {
                debugger;
                if (navigator.geolocation) {
                    navigator.geolocation.getCurrentPosition(
                        browserGeolocationSuccess,
                      browserGeolocationFail,
                      { maximumAge: 50000, timeout: 20000, enableHighAccuracy: true });
                }
            };
            tryGeolocation();
        });
    </script>

问题是，每当我运行此代码时，它总是给我不正确的纬度和经度值。我想知道我在做什么错。因此，如何在没有SSL连接的情况下使用地理位置定位

Answer 1

您可以使用我在W3schools上找到的简单Javascript代码

function getLocation() {
    if (navigator.geolocation) {
        navigator.geolocation.getCurrentPosition(showPosition);
    } else { 
        x.innerHTML = "Geolocation is not supported by this browser.";
    }
}

function showPosition(position) {
 alert('Latitude: '+position.coords.latitude +'Longitude: '+ position.coords.longitude);
}

Answer 2

你可以试试

<!DOCTYPE html>
<html>
<body>

<p>Click the button to get your coordinates.</p>

<button onclick="getLocation()">Try It</button>

<p id="demo"></p>

<script>
var x = document.getElementById("demo");


 
function getLocation() {
    if (navigator.geolocation) {
        navigator.geolocation.getCurrentPosition(showPosition);
    } else { 
        x.innerHTML = "Geolocation is not supported by this browser.";
    }
}

function showPosition(position) {
 var a = position.coords.latitude + ',' + position.coords.longitude;

 alert(a);
}
</script>

</body>
</html>
