为什么地理定位在移动浏览器上不起作用?

Why does geolocation not work on mobile browsers?

我正在尝试通过 HTML5 geolocation 获取用户的位置。 在台式机上它运行良好,但在我所有的移动设备(Samsung note、Samsung galaxy S4 和 Iphone 6)上它不工作并且不显示 error 对象。

这是我的代码:

function showPosition(position) {
    var coor = position.coords.longitude+", "+position.coords.latitude;
    alert(coor);
}
function errorPosition(error) {
    alert(error);
}
function toggleGeolocation() {
    navigator.geolocation.watchPosition(showPosition,errorPosition);
}

它要求获得地理定位许可,我单击允许(gps 正在工作)。可能是什么问题?

我在所有设备上使用 Google Chrome。

尝试使用此代码,它应该可以工作。

var successHandler = function(position) { 
alert(position.coords.latitude); 
alert(position.coords.longitude); 
}; 

var errorHandler = function (errorObj) { 
alert(errorObj.code + ": " + errorObj.message); 

alert("something wrong take this lat " + 26.0546106 ); 
alert("something wrong take this lng " +-98.3939791); 

}; 

navigator.geolocation.getCurrentPosition( 
successHandler, errorHandler, 
{enableHighAccuracy: true, maximumAge: 10000});

Navigator 仅适用于 Android https 网站。 这是一个示例,如果使用 http 则不会显示错误,但可以在 https 上正常工作(来自 https://www.w3schools.com/HTML/tryit.asp?filename=tryhtml5_geolocation

嗨@jordan,我面临着与我所做的相同的事情

首先确保您已更新设备上的 chrome 浏览器。

  1. 已启动第一个移动设备的定位服务

  2. 在加载时调用了 getLocation() 函数

通过这样做,它询问了我的许可并且效果很好。

    // google geolocation
    googleMap: function(func){
        if (navigator.geolocation) {

            //get location
            navigator.geolocation.getCurrentPosition(function(position) {
                var coords = position.coords;
                lat = coords.latitude;
                lng = coords.longitude;

                var latlng = new google.maps.LatLng(lat, lng);
                var geocoder = new google.maps.Geocoder();
                geocoder.geocode( {'location': latlng}, function(results, status) {
                    if (status == google.maps.GeocoderStatus.OK) {

                        var time = Date.parse(new Date());
                        var resultArr = results[0].address_components, address = "" ,LocationName = "",province = "",city = "",district = "";

                        for (var i = 0; i < resultArr.length; i++) {
                            var type = resultArr[i].types[0] ? resultArr[i].types[0] : 0;
                            if (type && type == "street_number") {
                                LocationName = resultArr[i].short_name;
                            }
                            if (type && type == "route") {
                                address = address + resultArr[i].short_name;
                            }
                            if (type && type == "political") {
                                district = resultArr[i].short_name;
                            }
                            if (type && type == "locality") {
                                city = resultArr[i].short_name;
                            }
                            if (type && type == "administrative_area_level_1") {
                                province = resultArr[i].short_name;
                            }
                        }

                        var data = {'name': LocationName + ' ' + address, 'address': address, 'lng': lng, 'lat': lat, 'province': province, 'city': city, 'district': district};
                        func(data);

                    } else {
                        func();
                        alert('Geocode was not successful for the following reason: ' + status);
                    }
                });

            }, function getError(error){
                func();
                switch(error.code){
                    case error.TIMEOUT:

                    HN_Location.getLocationByGeocoding(g);
                }else{
                    // getLocationError(f);
                    HN_Location.init(func, true);

我完全同意你的情况。很难找到答案...
