推荐答案
相关问题:
- 按照您想要获取路线的顺序放置位置数组.
var locations = [
['Manly Beach', -33.80010128657071, 151.28747820854187, 2],
['Bondi Beach', -33.890542, 151.274856, 4],
['Coogee Beach', -33.923036, 151.259052, 5],
['Maroubra Beach', -33.950198, 151.259302, 1],
['Cronulla Beach', -34.028249, 151.157507, 3]
];
- 使用
DirectionsService 的请求>origindestination中的最后一个标记，把剩下的推入 waypoints 数组:
- create the request for the DirectionsService with the first marker in
originthe last marker indestination, push the rest into the waypoints array:
if (i == 0) request.origin = marker.getPosition();
else if (i == locations.length - 1) request.destination = marker.getPosition();
else {
if (!request.waypoints) request.waypoints = [];
request.waypoints.push({
location: marker.getPosition(),
stopover: true
});
}
- 致电路线服务.
directionsService.route(request, function(result, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(result);
}
});
