Question

是否有任何想法使用Geolocation API查找我所在位置附近的商店？一个示例代码应该没问题然后我会继续。

Answer 1

您可以使用地理位置API获取当前位置。

然后你给谷歌地图的经度和纬度以及搜索查询，谷歌地图将返回你的地图，你必须把标记位置放在哪里：

                timeout: 5000,
                maximumAge: 0
            };


            var x = null;

            function success(position) {
                var lat = position.coords.latitude;
                var lon = position.coords.longitude;
                var accuracyInMeters = position.coords.accuracy;


                x.innerHTML = "Latitude: " + position.coords.latitude + "<br>Longitude: " + position.coords.longitude;
            }


            function error(err)
            {
                console.warn('ERROR(' + err.code + '): ' + err.message);
                x.innerHTML = '<span style="color: red;">No fix on location</span>';
            }

            function getLocation() {
                if (navigator.geolocation) {
                    // https://developer.mozilla.org/en-US/docs/Web/API/Geolocation.getCurrentPosition
                    // First of all, realise that the default timeout for getCurrentPosition is infinite(!). 
                    // That means that your error handler will never be called if getCurrentPosition hangs somewhere on the back end.

                    navigator.geolocation.getCurrentPosition(success, error, options); // Error and optios can be omitted
                } else {
                    alert("not supported")
                    x.innerHTML = "Geolocation is not supported by this browser.";
                }

            }





            document.addEventListener('DOMContentLoaded', function ()
            {
                x = document.getElementById("demo");
                /*fun code to run*/
                getLocation();
            })




            // ]]>
        </script>


        <style type="text/css" media="all">
            html, body {
                width: 100%;
                height: 100%;
                margin: 0px;
                padding: 0px;
            }

        </style>


    </head>
    <body>
        <div id="demo"></div>

    </body>
</html>

如果浏览器不支持地理位置，那么您可以使用 - 使用IP解析城镇的地理坐标，并使用其长/拉 - 或者您可以要求用户输入他的地址，并从那里获得经度/纬度：

function searchLocations() {
  var address = document.getElementById("addressInput").value;
  var geocoder = new google.maps.Geocoder();
  geocoder.geocode({address: address}, function(results, status) {
    if (status == google.maps.GeocoderStatus.OK) {
      searchLocationsNear(results[0].geometry.location);
    } else {
      alert(address + ' not found');
    }
  });
}

您可以将商店的位置放入数据库表并在那里查找其坐标，而不是从谷歌中获取最近的商店。
看这里的例子： https://developers.google.com/maps/articles/phpsqlsearch_v3

要获取某个位置附近的商店列表，您可以使用 Google Places API
https://developers.google.com/places/documentation/?csw=1
或者你可以在这里使用StoreLocater库：
