Question

我有像

这样的要求

Source,
waypoint 1,
waypoint 2,
waypoint 3,
Destination

我需要Source到waypoint 1的路径是一种颜色，waypoint 1到waypoint 2是另一种颜色。

这里我得到的整个路径以单（红色）颜色显示。但是当我们移动到下一个航点时我需要改变不同的颜色

  mapSite.getDirection = function(latitudeValue, longitudeValue, waypts) {

        document.getElementById('directionsPanel').innerHTML = "";
        directionsDisplay = new google.maps.DirectionsRenderer({
        polylineOptions: {
        strokeColor: "red"
        }
    });
        var site = new google.maps.LatLng(latitudeValue, longitudeValue);

        var mapOptions = {
            center: site,
            zoom: 9,
            mapTypeId: google.maps.MapTypeId.ROADMAP

        }
        map = new google.maps.Map(document.getElementById('map'), mapOptions);
        mapSite.map = map;

            directionsDisplay.setMap(mapSite.map);
            var start = mapSite.latitude + "," + mapSite.longitude;                             
            var end = latitudeValue + "," + longitudeValue;

            var request = {
                origin: start,
                destination: end,
                waypoints: waypts,
                travelMode: google.maps.TravelMode.DRIVING
            };

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

                directionsDisplay.setDirections(response);
                   var route = response.routes[0];
                   directionsDisplay.setPanel(document.getElementById('directionsPanel'));

                } 
           });
   };

我认为最简单的方法是多次调用方向api。例如，Source-＆gt; waypoint 1，waypoint 1-＆gt; waypoint 2，waypoint 2-＆gt; waypoint 3，waypoint 3-＆gt; Destination ...

否则，您从回调函数response获得directionsService.route(request, function(response, status) {，其中包含带有legs的{{1}}和折线。您可以自己绘制路线，而不是调用steps
