Question

真的需要一些想法。一直在使用谷歌地图API，我使用地理编码，反向地理编码和地理位置。通过下面这段代码，我可以使用Google地图的Direction API，它可以很好地运行。

    var locations = [
        {lat: 6.4261139, lng: 3.4363691}
    ];

    var mapContainer = $('.map-container'),
        map          = new google.maps.Map(mapContainer[0], {
            center: center,
            zoom  : 10
        });

    var markers = _(locations)
        .map(function (loc) {
            return new google.maps.Marker({
                position: new google.maps.LatLng(loc.lat, loc.lng)
            });
        })
        .each(function (marker) {
            marker.setMap(map);
        })
        .value();

    var mc = new MarkerClusterer(map, markers);

    var directionsService = new google.maps.DirectionsService(),
        directionsDisplay = new google.maps.DirectionsRenderer(),
        displayRoute      = function () {
            directionsService.route({
                origin: 'Akin Ogunlewe street VI',//6.512596400000001+','+3.3541297 Pass this in place of the address
                destination: 'Falolu road Surulere',//'Falolu road Surulere',//6.4261139+','+3.4363691 Pass this in place of the address
                travelMode : google.maps.TravelMode.DRIVING
            }, function (response, status) {
                if (status === google.maps.DirectionsStatus.OK) {
                    directionsDisplay.setDirections(response);
                } else {
                    console.log('Directions request failed due to ' + status);
                }
            });
        };

directionsDisplay.setMap(map);
displayRoute();

我有没有办法在Latitude和Longitude中传递Origin和Destination而不是物理地址（字符串）？我尝试了但是没有用。

我需要传递数字（float）值，如：6.512596400000001,3.3541297而不是Falolu road Surulere

感谢任何帮助

Answer 1

documentation for the v3 API表示google.maps.LatLng或字符串。对于地理位置，请创建并传入google.maps.LatLng;对于地址，传入一个字符串。

origin：LatLng |字符串| google.maps.Place，目的地：LatLng |字符串| google.maps.Place，

在reference

中

目的地|类型：地点|目的地的位置。这可以指定为要进行地理编码的字符串，或LatLng或Place。必需的。

原产地|放置|原产地。这可以指定为要进行地理编码的字符串，或LatLng或Place。必需的。
