我在我的网站上使用这个脚本:
<script src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script>
(function () {
var directionsService = new google.maps.DirectionsService(),
directionsDisplay = new google.maps.DirectionsRenderer(),
createMap = function (start) {
var travel = {
origin : (start.coords)? new google.maps.LatLng(start.lat, start.lng) : start.address,
destination : "Warszawa, al. jerozolimskie 123",
travelMode : google.maps.DirectionsTravelMode.DRIVING
// Exchanging DRIVING to WALKING above can prove quite amusing :-)
},
mapOptions = {
zoom: 10,
// Default view: downtown Stockholm
center : new google.maps.LatLng(59.3325215, 18.0643818),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map"), mapOptions);
directionsDisplay.setMap(map);
directionsDisplay.setPanel(document.getElementById("map-directions"));
directionsService.route(travel, function(result, status) {
if (status === google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(result);
}
});
};
// Check for geolocation support
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function (position) {
// Success!
createMap({
coords : true,
lat : position.coords.latitude,
lng : position.coords.longitude
});
},
function () {
// Gelocation fallback: Defaults to Stockholm, Sweden
createMap({
coords : false,
address : "Polska, Warszawa"
});
}
);
}
else {
// No geolocation fallback: Defaults to Lisbon, Portugal
createMap({
coords : false,
address : "Polska, Warszawa"
});
}
})();
</script>
我在连接计算我的位置和设定位置之间的道路距离的 Haversine 公式时遇到问题......我不需要任何地图或道路线 - 只有公里数:)
有人帮我解决这个问题吗?
非常感谢,
