谷歌地图API有这个:)服务..有你更读到这里 https://developers.google.com/maps/documentation/javascript/directions

示例代码

var directionsDisplay; 
var directionsService = new google.maps.DirectionsService(); 
var map; 

function initialize() { 
    directionsDisplay = new google.maps.DirectionsRenderer(); 
    var chicago = new google.maps.LatLng(41.850033, -87.6500523); 
    var mapOptions = { 
    zoom:7, 
    center: chicago 
    } 
    map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions); 
    directionsDisplay.setMap(map); 
} 

function calcRoute() { 
    var start = document.getElementById("start").value; 
    var end = document.getElementById("end").value; 
    var request = { 
    origin:start, 
    destination:end, 
    travelMode: google.maps.TravelMode.DRIVING 
    }; 
    directionsService.route(request, function(result, status) { 
    if (status == google.maps.DirectionsStatus.OK) { 
     directionsDisplay.setDirections(result); 
    } 
    }); 
}

如果你只想得到远处不需要的地图。喊你尝试谷歌地图服务API JSON，在这里阅读更多

https://developers.google.com/maps/documentation/directions/

样本请求URL https://maps.googleapis.com/maps/api/directions/json?origin=Toronto&destination=Montreal&avoid=highways&mode=bicycling&key=API_KEY

日Thnx先生，但我认为这个代码将被显示的地图，很感兴趣只有距离。 –
