I want to change the default icon of marker when I search route between two locations. How can I do it? I use this code but I didn't get only the map without route and points
var start = new google.maps.Marker({
position: new google.maps.LatLng(lat, lon),
icon:'.png',
map: map });
var end = new google.maps.Marker({
position: new google.maps.LatLng(lat1, long1),
icon:'.png',
map: map });
var request = {
origin: start,
destination: end,
optimizeWaypoints: true,
travelMode: google.maps.DirectionsTravelMode.DRIVING
};
I want to change the default icon of marker when I search route between two locations. How can I do it? I use this code but I didn't get only the map without route and points
var start = new google.maps.Marker({
position: new google.maps.LatLng(lat, lon),
icon:'http://www.google./mapfiles/dd-start.png',
map: map });
var end = new google.maps.Marker({
position: new google.maps.LatLng(lat1, long1),
icon:'http://www.google./mapfiles/dd-end.png',
map: map });
var request = {
origin: start,
destination: end,
optimizeWaypoints: true,
travelMode: google.maps.DirectionsTravelMode.DRIVING
};
- Is it clear now?? I change my question. I want to change the default icon (marker with letter). I want to change this icon with 'google./mapfiles/dd-start.png' on the point of source and for destination I want to put this picture google./mapfiles/dd-end.png – mobileDeveloper Commented Apr 2, 2012 at 15:41
- Aha, you mean that instead of using the default icons, you want to use custom icons. – Roy Dictus Commented Apr 2, 2012 at 15:45
- yes I want to use custom icon of marker when I search the route – mobileDeveloper Commented Apr 2, 2012 at 15:46
- Most of that code isn't even valid. – Octavian Helm Commented Apr 2, 2012 at 16:56

Reset to default 3When you create the renderer add this option, then place your markers at the origin (start) and destination(end)
directionsDisplay = new google.maps.DirectionsRenderer({
suppressMarkers: true
});
here is the working example, change according to your requirement.

Ok, my try:
- Set
visible = falseanddraggable = trueinDirectionsRendererOptionsobject - Create
DirectionsRendererobject - Create markers on your own (with
draggable=trueoption) Pass
dragstartanddragevent from your marker to renderer markers (start and end)google.maps.event.addListener(marker_start, 'dragstart', function(e) { directionsRenderer.b.markers[0].setPosition(this.getPosition()); google.maps.event.trigger(directionsRenderer.b.markers[0], 'dragstart', e); }); google.maps.event.addListener(marker_start, 'drag', function(e) { directionsRenderer.b.markers[0].setPosition(this.getPosition()); google.maps.event.trigger(directionsRenderer.b.markers[0], 'drag', e); }); google.maps.event.addListener(marker_end, 'dragstart', function(e) { var l = directionsRenderer.b.markers.length - 1; directionsRenderer.b.markers[l].setPosition(this.getPosition()); google.maps.event.trigger(directionsRenderer.b.markers[l], 'dragstart', e); }); google.maps.event.addListener(marker_end, 'drag', function(e) { var l = directionsRenderer.b.markers.length - 1; directionsRenderer.b.markers[l].setPosition(this.getPosition()); google.maps.event.trigger(directionsRenderer.b.markers[l], 'drag', e); });
You can change the icon of all markers by the next line of code:
directionsDisplay = new google.maps.DirectionsRenderer({
markerOptions:{
icon:"put_here_the_url_to_your_icon",
},
});
If you want use different icon for each marker on the map, you can create each markers with its own positions and icons using Marker constructor:
new google.maps.Marker({
position: {lat: 37.753212, lng: 14.991608}, //Example
map: map,
icon: your_marker_image
});
(you can use your newly created markers as start, end or waypoints markers). Then pass to the DirectionRenderer constructor the current object (markerOption):
directionsDisplay = new google.maps.DirectionsRenderer({
markerOptions:{
visible:false,
},
});
So the markers of the direction service are not showed.
