I'm using Google Maps API to create a direction with the given points.
I need to order the points as 1,2,3...99 (It's done).
Also the points must be draggable.
But when I make the points draggable, the direction does not refresh itself, point's locations change but not the direction,
Here is the sample code(taken from the --> Google Maps Directions using 1-2-3 instead of A-B-C);
<script type="text/javascript" src="http://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load("maps", "3",{other_params:"sensor=false"});
function init(){
directionsService = new google.maps.DirectionsService();
var pos = new google.maps.LatLng(41.218624, -73.748358);
var myOptions = {
zoom: 15,
center: pos,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map'), myOptions);
directionsDisplay = new google.maps.DirectionsRenderer({map: map, suppressMarkers: true,draggable:true});
directionsService.route({
origin: "New York",
destination: "Chicago",
waypoints: [{location:"Philadelphia"}, {location:"Boston"}], //other duration points
optimizeWaypoints: true,
travelMode: google.maps.TravelMode.DRIVING
}, function(response, status) {
if (status === google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
var my_route = response.routes[0];
for (var i = 0; i < my_route.legs.length; i++) {
var marker = new google.maps.Marker({
position: my_route.legs[i].start_location,
draggable:true,
label: ""+(i+1),
map: map
});
}
var marker = new google.maps.Marker({
position: my_route.legs[i-1].end_location,
draggable:true,
label: ""+(i+1),
map: map
});
} else {
vts.alertDialog( window.localization.error,
window.localization.error_direction_calculate + ": " + status,
BootstrapDialog.TYPE_DANGER);
}
});
}
</script>
<body style="margin:0px; padding:0px;" onload="init()">
<div id="map" style="height:400px; width:500px;"></div>
</body>
Here is the screen shots;
Here is the problem;
The thing is that, I have to do it with both markers and draggable properties.
Thanks in advance
Just recalculate the route every time a marker is dragged. Listen for the dragend event and calculate route again and then render it on map, again with suppressing markers. Careful though, if you drag a marker to some position where route cannot be calculated (e.g. over sea, or some mountains, etc.) you would get error when re-calculating the route.
Working example:
function init(){
var markers = [];
var directionsService = new google.maps.DirectionsService();
var pos = new google.maps.LatLng(41.218624, -73.748358);
var myOptions = {
zoom: 15,
center: pos,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map'), myOptions);
directionsDisplay = new google.maps.DirectionsRenderer({map: map, suppressMarkers: true});
directionsService.route({
origin: "New York",
destination: "Chicago",
waypoints: [{location:"Philadelphia"}, {location:"Boston"}], //other duration points
optimizeWaypoints: true,
travelMode: google.maps.TravelMode.DRIVING
}, function(response, status) {
if (status === google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
var my_route = response.routes[0];
for (var i = 0; i < my_route.legs.length; i++) {
addDraggableDirectionsMarker(my_route.legs[i].start_location, i+1, map, markers, directionsService, directionsDisplay);
}
addDraggableDirectionsMarker(my_route.legs[i-1].end_location, i+1, map, markers, directionsService, directionsDisplay);
} else {
vts.alertDialog( window.localization.error,
window.localization.error_direction_calculate + ": " + status,
BootstrapDialog.TYPE_DANGER);
}
});
}
function addDraggableDirectionsMarker(position, label, map, markers, directionsService, directionsDisplay){
var marker = new google.maps.Marker({
position: position,
label: "" + label,
map: map,
draggable: true
});
google.maps.event.addListener(marker, 'click', function(){
//do whatever you want on marker click
});
google.maps.event.addListener(marker, 'dragend', function(){
if(markers.length < 2) return;
var waypoints = [];
for(var i = 1; i < markers.length - 1; i++) waypoints.push({location:markers[i].getPosition()});
directionsService.route({
origin: markers[0].getPosition(),
destination: markers[markers.length-1].getPosition(),
waypoints: waypoints,
optimizeWaypoints: true,
travelMode: google.maps.TravelMode.DRIVING
}, function(response, status) {
if (status === google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
//uncomment following code if you want the markers you dragged to snap to the route, closest to the point where you dragged the marker

I'm using the Google Maps API on Google Maps.
The thing is that, It shows me several stations throughout the path, labeling them as A-B-C-D...Z, but I need to change it as 1-2-3-4-..99,
Here is my code;
directionsService.route({
origin: $( "#input-directions-start-point" ).val(),
destination: $( "#input-directions-end-point" ).val(),
waypoints: waypts, //other duration points
optimizeWaypoints: true,
travelMode: google.maps.TravelMode.DRIVING
}, function(response, status) {
if (status === google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
console.log(response);
} else {
vts.alertDialog( window.localization.error,
window.localization.error_direction_calculate + ": " + status,
BootstrapDialog.TYPE_DANGER);
}
});
Here is the Screen Shot;
Thanks in Advance
google.maps.DirectionsRendererOptions has property suppressMarkers which when you set to true, will only render the path but not markers.
You can then render the markers yourself using for example google.maps.Marker, which has label attribute using which you can specify the label inside the marker, which can be for example a number (You can also create your own very custom marker by extending google.maps.OverlayView class, or use RichMarker library). The position of the markers on route can be parsed from response object of directionsService.
More in docs.
Working example:
function init(){
directionsService = new google.maps.DirectionsService();
var pos = new google.maps.LatLng(41.218624, -73.748358);
var myOptions = {
zoom: 15,
center: pos,
mapTypeId: google.maps.MapTypeId.ROADMAP

map = new google.maps.Map(document.getElementById('map'), myOptions);
directionsDisplay = new google.maps.DirectionsRenderer({map: map, suppressMarkers: true});
directionsService.route({
origin: "New York",
destination: "Chicago",
waypoints: [{location:"Philadelphia"}, {location:"Boston"}], //other duration points
optimizeWaypoints: true,
travelMode: google.maps.TravelMode.DRIVING
}, function(response, status) {
if (status === google.maps.DirectionsStatus.OK) {

Currently I have encounter a problem. I used and changed sample API to draw route for two points. Point A is current location. Point B is one of the multiple markers' location. Those markers are created which I call nearby search function.
function showInfoWindow() {
var marker = this;
places.getDetails({
placeId: marker.placeResult.place_id
},
function(place, status) {
if (status !== google.maps.places.PlacesServiceStatus.OK) {
return;
}
infoWindow.open(map, marker);
buildIWContent(place);
});
var clickLat = marker.position.lat();
var clickLon = marker.position.lng();
var directionsDisplay = new google.maps.DirectionsRenderer({
map: map
});
var directionsService = new google.maps.DirectionsService();
showRoute(clickLat, clickLon, directionsDisplay, directionsService);
}
function showRoute(clickLat, clickLon, directionsDisplay, directionsService) {
var pointA = {
lat: currentLat,
lng: currentLon
};
var pointB = {
lat: clickLat,
lng: clickLon
};
directionsDisplay.setOptions({
suppressMarkers: true
});
//directionsDisplay.setMap(map);
//directionsDisplay.setDirections({ routes: [] });
// Set destination, origin and travel mode.
var request = {
destination: pointB,
origin: pointA,
travelMode: google.maps.TravelMode.DRIVING
};
//directionsDisplay.setMap(null);
// Pass the directions request to the directions service.
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
// Display the route on the map.
//directionsDisplay.set('directions', null);
//directionsDisplay.setMap(map);
//directionsDisplay.setDirections({ routes: [] });
directionsDisplay.setDirections(response);
} else {
window.alert('Directions request failed due to ' + status);
}
});
}
These codes could draw route for two points already. But the problem is when I click one marker call the showInfoWindow() it will draw one route, and click another one when it will call the showInfoWindow() again it will draw another route remaining the previous one route.I want to clear the previous one route. Tried all the methods online and could not find the reason.
If you only want one directions result displayed on the map at the time, only create and use one instance of the DirectionsRenderer, currently you create a new one for every result from the DirectionsService.

I'm trying to display how distance and how minutes are between two markers in Google Maps API v3 and use these information to override the default infoWindow text that appears when the directionsService is fired, I think there is a asyncronous problem with calcRoute() and the infoWindows. This is an example code that reproduces the error.

Please note that if you click one marker, and then another, the second marker will show the desired result but that information belongs to the first marker... How can I force the order of execution to avoid the async?
Thanks in advance...
You want to open the infowindow in the DirectionsService callback function where the data is available.
(you may also want to suppress the existing markers from the directions service)
InfoWindow click listener:
google.maps.event.addListener(marker, 'click', (function (marker, i) {
return function () {
calcRoute(locations[i][1], locations[i][2]);
infowindow.open(map, marker);
}
})(marker, i));
Updated calcRoute function:
function calcRoute(latdest, lngdest) {
var start = new google.maps.LatLng(-23.571064, -46.645424);
var end = new google.maps.LatLng(latdest, lngdest)
var request = {
origin: start,
destination: end,
travelMode: google.maps.TravelMode.DRIVING
};
directionsService.route(request, function (result, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(result);
infowindow.setContent(directionsDisplay.directions.routes[0].legs[0].distance.text + " - " + directionsDisplay.directions.routes[0].legs[0].duration.text);
}
});

I'm working on a site that uses google maps v3, thanks to which you can navigate to a specific location
web site - http://dev.fama.net.pl/walendia/lokalizacja.html
type 'szczecin' on input that is at the top of the site and click submit - a marker will appear on the map, then type 'warszawa' - new marker will appear on the map but old one is still there, how to remove previous marker from the map

HTML CODE
$(document).ready(function() {
initialize('Łączności 131, 05-552 Łazy, Polska', 10);
addMarker2(location);
});
Before adding second marker you need to delete marker from markersArray. Use the following function to delete markers from array.
function deleteMarkers() {
if (markersArray) {
for (i=0; i < markersArray.length; i++) {
markersArray[i].setMap(null);
}
markersArray.length = 0;
}
}
DEMO FIDDLE
NOTE: I just took some sample to remove and show markers when you click on buttons. Use those functions according to your requirement.
