Need help in Google Map V3
I want to display multiple points in the route.
Currently i have mentioned origin and destination, but how can I display all the points which I have in the waypoint (arrWaypoints) array?
Below is my code.
var origin = arrWaypoints[0];
var destination = arrWaypoints[1];
this.directions.route({
origin: origin,
destination: destination,
travelMode: google.maps.DirectionsTravelMode.DRIVING,
unitSystem: google.maps.DirectionsUnitSystem.METRIC
}, function(result, status) {
........
Thanks,

In your example, there are no waypoints to display. If you have additional waypoints to include, the request would look something like this:
var origin = arrWaypoints[0];
var destination = arrWaypoints[arrWaypoints.length-1];
// Origin and destination don't need to be in the arrWaypoints anymore as they're listed separately in the request.
arrWaypoints.splice(arrWaypoints.length-1, 1);
arrWaypoints.splice(0, 1);
this.directions.route({
origin: origin,
destination: destination,
waypoints: arrWaypoints,
travelMode: google.maps.DirectionsTravelMode.DRIVING,
unitSystem: google.maps.DirectionsUnitSystem.METRIC
}, function(result, status) {

I'm currently using the Google Maps API to find transit routes between two locations. It works fine on almost all occassions, except when the destination is Schiphol, Netherlands (the national Dutch airport).
No matter what the starting location is, the Google Maps API won't find any transit routes that lead to Schiphol. Strange, because when I enter the exact same locations on http://maps.google.com, Google finds plenty of routes. Also, everything works fine when Schiphol, Netherlands is the starting point.
Please refer to this JSFiddle, or the code below.
var directionsService = new google.maps.DirectionsService;
directionsService.route({
origin: 'Rotterdam, Netherlands',
destination: 'Schiphol, Netherlands', // Change this to e.g. 'The Hague, Netherlands' and it works.
travelMode: google.maps.TravelMode.TRANSIT,
}, function(response, status) {
if (status === google.maps.DirectionsStatus.OK) {
var route = response.routes[0].legs[0];
window.alert('When Schiphol is destination: noute found!')
} else {
window.alert('When Schiphol is destination: no transit routes found.')
}
});
directionsService.route({
origin: 'Schiphol, Netherlands',
destination: 'Rotterdam, Netherlands',
travelMode: google.maps.TravelMode.TRANSIT,
}, function(response, status) {
if (status === google.maps.DirectionsStatus.OK) {
var route = response.routes[0].legs[0];
window.alert('When Schiphol is origin: route found!')
} else {
window.alert('When Schiphol is origin: no transit routes found.')
}
});
Migrating code from Javascript API 2 to 3. I have a list of locations which i need to plot in the form of a driving directions. This was done in v2 using the following code
directions = new GDirections(map);
directions.loadFromWaypoints(waypoints, {preserveViewport: true});
Here is my attempt at converting this to V3
var request = {
origin: startLoc,
destination: endLoc,
waypoints: waypoints,
optimizeWaypoints: true,
travelMode: google.maps.TravelMode.DRIVING
};
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
}
});
Not the whole code, but the general idea. Seems to work fine, with one little issue. When there are more than 8 waypoints, the call fails. This is expected since Google Maps API v3 Docs states
The maximum allowed waypoints is 8, plus the origin, and destination. Maps API for Business customers are allowed 23 waypoints, plus the origin, and destination. Waypoints are not supported for transit directions.
Since i didn't run in to this issue in v2, is this a new restriction with v3? I wonder if i am using something that was not designed for what i need. This is a very lightly used applicaton with 2 users, so i am not sure if an expensive business license is worth the return. Emails to Google maps team have not yet been returned. Any workarounds/pointers will be of great help. Thanks.
One possible work around (particularly for a lightly used site) is to use multiple DirectionsService requests.
example 1 (addresses)
example 2 (coordinates)
Use Should need to Use array concept like these...
directionsService[i].route({
'origin': start,
'destination': end
'waypoints': waypts,
'travelMode': 'DRIVING'
},
function (directions, status){
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay[j].setDirections(directions);
}
});
in these directionservice and directiondisplay are should be in array logic
and using looping concepts use should need to assign start,end and waypoints dynamically and
try sending multiple request means u ll get the route for n number of latlon's ...but the markers ll be repeat with same name after 8 waypoints for that we remove the default markers by using supressmarkers false property...
As others said, it's imposable to do it using Google's JavaScript API. However, Google does allow up to 23 waypoints with a server-side request. So using PHP and JavaScript, I was able to make a workaround.
What you have to do is get the "waypoint order" from the server side request and then have JavaScript give you directions between each location.
<?php
$startLocation = "40.713,-74.0135";
$endLocation = "40.75773,-73.985708";
$waypoints = array("40.748433,-73.985656|", "40.689167,-74.044444|");
$apiKey = "";
$routeData = json_decode(file_get_contents("https://maps.googleapis.com/maps/api/directions/json?origin=".$startLoc."&destination=".$endLoc."&waypoints=optimize:true|".$waypoints."&key=".$apiKey));
echo "var waypointsOrder = ". json_encode($routeData->routes[0]->waypoint_order) . ";\n";
?>
var startLocation = {lat: 40.713, lng: -74.0135};
var endLocation = {lat: 40.75773, lng: -73.985708};
//get directions from the origin to the first waypoint
var request = {
origin: startLocation,
destination: JSON.parse(places[waypointsOrder[0]][1]),
travelMode: google.maps.TravelMode.DRIVING
};
directionsService.route(request, function (result, status) {
if (status == google.maps.DirectionsStatus.OK) {
renderDirections(result, map);
}
});
//get directions from the last waypoint to the destination
var request = {
origin: JSON.parse(places[waypointsOrder[waypointsOrder.length-1]][1]),
destination: endLocation,
travelMode: google.maps.TravelMode.DRIVING
};
directionsService.route(request, function (result, status) {
if (status == google.maps.DirectionsStatus.OK) {
renderDirections(result, map);
}
});
//get directions between each waypoint
for (i = 1; i < waypointsOrder.length; i++) {
var request = {
origin: JSON.parse(places[waypointsOrder[i-1]][1]),
destination: JSON.parse(places[waypointsOrder[i]][1]),
travelMode: google.maps.TravelMode.DRIVING
};
directionsService.route(request, function (result, status) {
if (status == google.maps.DirectionsStatus.OK) {
renderDirections(result, map);
}
});
}
function renderDirections(result, map) {
var directionsDisplay = new google.maps.DirectionsRenderer ({
map: map
});
directionsDisplay.setMap(map);
directionsDisplay.setDirections(result);
}
When i enter source and destination it show me all suggested routes in direction panel. Let say it show me Route A, B and C. I want to get Route A road name, time and distance. Like "N5 Road 225 KM-about 3 hours 20 mins". I want to complete string. Please help me in this regard. Thanks
I just get route summary by using following code:
var request = {
origin: start,
destination: end,
provideRouteAlternatives: true,
travelMode: google.maps.TravelMode.DRIVING
};
directionsService.route(request, function (response, status) {
if (status == google.maps.DirectionsStatus.OK) {
response.routes[0].summary;
directionsDisplay.setDirections(response);
}
});
This is my code :
var request = {
origin: start,
destination: end,
travelMode: google.maps.DirectionsTravelMode.DRIVING
};
directionsService.route(request, function (response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
}
});
now, I'd like to put a marker after 200km from the point origin: start : is it possible?
Here is an example that puts two markers on a route (one at 9.5km and one at 64.8km):
http://www.geocodezip.com/v3_GoogleEx_directions-waypoints_kmmarkersC.html
(so, yes, it is possible)
This example was created before the geometry library was released, and might be able to be re-written to use that.
I tried something which is a bit out of norm on google map. What I am trying to achieve is to draw a route with multiple waypoints which are sometimes can be repeative. Let says, an Origin: A and Destination: B, and waypoints {1, 2, 3, 4, 5, 6, 7, 3, 2, 1}
From above, it will always failed. If I take out the repeat locations it will display the route.
Please help. Thanks in advanced.
wayPoints.push(
{location:new google.maps.LatLng(stepsWP[0], stepsWP[1]),
stopover: false
}
...
var request = {
origin: start,
destination: end,
waypoints: wayPoints,
optimizeWaypoints: false,
travelMode: google.maps.TravelMode.DRIVING
};
var directionsRen = new google.maps.DirectionsRenderer(rendererOptions);
directionsRen.setMap(map);
directionsService.route(request, function(result, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsRen.setDirections(result);
}else{
console.debug('Something wrong with google...');
}
});
Thanks.
I did some google and found some of the suggestions on the workaround.

Here is what I got from Google Map Direction service page:
The maximum allowed waypoints is 8, plus the origin, and destination.
Google Maps API for Work customers are allowed 23 waypoints, plus the
origin, and destination. Waypoints are not supported for transit
directions.
So you basically need to break down your waypoints array into groups of 8 locations and use that to send requests to google direction service api.
