javascript - 显示路线的谷歌地图

Question

根据谷歌地图，我可以规划一条跨越多个航路点的路线。这里有解释:http://code.google.com/intl/nl-NL/apis/maps/documentation/javascript/services.html#Routes

现在 api 要我像这样添加航路点:

location: waypoints

所以 waypoints 是一个数组，我必须将其分配给 location: 参数，但从我在演示中看到的情况来看，它们用位置字符串填充数组。我想知道是否可以传递纬度和经度而不是字符串？

更新:这是我尝试创建路线的部分。我现在已经在整个循环中将相同的值放在位置中，但是如果我既不使用变量值，id 也不起作用

function calcRoute() {

    var waypts = [];

    for (var i in owt.stores.spotStore.data.map) {
        waypts.push({
            location:  new google.maps.LatLng(12.3, -33.6),
            stopover:true
        });
        console.log(waypts);
    }
    var request = {
        origin: new google.maps.LatLng(50.82788, 3.26499),
        destination: new google.maps.LatLng(50.82788, 3.26499),
        waypoints: waypts,
        optimizeWaypoints: true,
        travelMode: google.maps.DirectionsTravelMode.DRIVING
    };

    directionsService.route(request, function(response, status) {
        if (status == google.maps.DirectionsStatus.OK) {
            directionsDisplay.setDirections(response);
        }
    });
}
;

根据API reference :

A DirectionsWaypoint represents a location between origin and destination through which the trip should be routed.

location LatLng|string Waypoint location. Can be an address string or LatLng. Optional

因此创建一个具有经纬度值的新 Waypoint 应该如下所示

return {
    location:new google.maps.LatLng(12.3, -33.6),
    stopover:true
};
