Im using below code to show a distance between two distances but zoom doesn't work it always will be in default zoom level. I tried setting lot of values but it's not working. Please help.
var directionsDisplay;
var directionsService = new google.maps.DirectionsService();
var map;
var from = "";
function initialize() {
directionsDisplay = new google.maps.DirectionsRenderer();
directionsDisplay.preserveViewport = false;
var dallas = new google.maps.LatLng(32.8931567, -97.0402193);
var mapOptions = {
zoom: 15,
center: dallas
};
map = new google.maps.Map(document.getElementById('googleMap'), mapOptions);
map.setZoom(map.getZoom()+5);
directionsDisplay.setMap(map);
calcRoute();
}
function calcRoute() {
var start = 'dallas airport terminal a';
var end = 'SpringHill Suites';
console.log("HotelDetail: " + end);
var request = {
origin: start,
destination: end,
travelMode: google.maps.TravelMode.DRIVING
};
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
}
});
}
google.maps.event.addDomListener(window, 'load', initialize);
For what you want to achieve, the preserveViewport property needs to be set to true like this.
directionsDisplay = new google.maps.DirectionsRenderer({
preserveViewport: true
});
//directionsDisplay.preserveViewport = false;
In addition, your code sets a zoom level of 20 which is too high to see anything on the map. Here is a working example with an initial zoom level of 12: JSFiddle

The below code shows two points in the map and draws the driving path between those points. What I'm trying to achieve is when I move a point, it should move the marker and re-draw the path. How can I do that? I appreciate any hints. Thanks.
function mapLocation() {
var directionsDisplay;
var directionsService = new google.maps.DirectionsService();
var map;
function initialize() {
directionsDisplay = new google.maps.DirectionsRenderer();
var istanbul = new google.maps.LatLng(41.015137, 28.979530);
var mapOptions = {
zoom: 7,
center: istanbul
};
map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
directionsDisplay.setMap(map);
calcRoute();
}
function calcRoute() {
var start = new google.maps.LatLng(41.01524, 28.975994);
//var end = new google.maps.LatLng(38.334818, -181.884886);
var end = new google.maps.LatLng(41.013232, 28.978676);
var request = {
origin: start,
destination: end,
travelMode: google.maps.TravelMode.DRIVING
};
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
directionsDisplay.setMap(map);
} else {
alert("Directions Request from " + start.toUrlValue(6) + " to " + end.toUrlValue(6) + " failed: " + status);
}
});
}
google.maps.event.addDomListener(window, 'load', initialize);
}
mapLocation();
You can set the draggable option of the DirectionsRendererOptions to true and pass it to the DirectionsRenderer to allow users to edit the rendered route(s).
directionsDisplay = new google.maps.DirectionsRenderer({
draggable: true
});
See the documentation.
I have this Javascript code on Google maps with geolocation and direction and I am using it in cordova , it gives me problems because it lacks the event Deviceready.
I tried to put it , but it was not working.
You are able to add it in the right way ?
Code:
var directionsDisplay;
var directionsService = new google.maps.DirectionsService();
var map;
// default location. When geolocation tracks the client, this variable is set to that location
function initialize() {
var mapOptions = {
zoom: 15,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
directionsDisplay = new google.maps.DirectionsRenderer();
map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
//here there is marker
directionsDisplay.setMap(map);
map.setCenter(mylocation);
}
function updateRoute() {
calcRoute(mylocation);
}
function calcRoute(start) {
var start = mylocation;
var end = document.getElementById('end').value;
var request = {
origin:start,
destination:end,
travelMode: google.maps.TravelMode.WALKING,
};
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
}
});
}
// Try HTML5 geolocation
if(navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position) {
mylocation = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
//document.getElementById('start').value = ;
if (map) {
calcRoute(position.coords.latitude +','+ position.coords.longitude);
map.setCenter(mylocation);
//*Posizione Utente*//
var image = 'user.png'
var marker1 = new google.maps.Marker({
position: mylocation,
map: map,
title: 'ciao!',
icon: image
});
google.maps.event.addListener(marker1, 'click', function() {
infowindow1.open(map,marker1);
});
var infowindow1 = new google.maps.InfoWindow({
content: '<img src="user.png">Sono Qui.....'
});
}
})
}
google.maps.event.addDomListener(window, 'load', initialize);
I try to make directions for my current position and marker coordinate. so i get latitude and longitude using getcurrentposition. then, i mark it.
function initialize() {
directionsDisplay = new google.maps.DirectionsRenderer();
var node = new google.maps.LatLng(-7.276442,112.791174);
var mapOptions = {
zoom: 15,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map'),
mapOptions);
directionsDisplay.setMap(map);
navigator.geolocation.getCurrentPosition(function(position) {
pos = new google.maps.LatLng(position.coords.latitude,
position.coords.longitude);
var marker = new google.maps.Marker({
position : pos,
map: map,
title:'Lokasi Anda'
});
var marker1 = new google.maps.Marker({
position : node,
map: map,
title:'Lokasi Anda'
});
map.setCenter(pos);
}, function() {
handleNoGeolocation(true);
});
}
then, I calculate it using this function.
function calcRoute() {
var request = {
origin:pos,
destination:node,
travelMode: google.maps.DirectionsTravelMode.DRIVING
};
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
}
});
}
but why i can't see direction from pos to node. any suggestion ?
If I call the calcRoute function (and pass in the "pos" and "node" locations, it can't find directions between where I am (in the US) and where the point is located (Raya Its, Sukolilo, Surabaya City, East Java 60117, Republic of Indonesia). The DirectionsService returns a status of "ZERO_RESULTS".
ZERO_RESULTS No route could be found between the origin and destination.
working example
function calcRoute(pos,node) {
var directionsService = new google.maps.DirectionsService();
var request = {
origin:pos,
destination:node,
travelMode: google.maps.DirectionsTravelMode.DRIVING
};
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
} else { alert("Directions failed: "+status); }
});
}
I am unable to create custom polyline for transit directions on Google API. Only part of the route is rendered, not all. It works for driving, walking & cycling but not for transit. Not sure what exactly am I missing. If someone has faced the same issue, please help!
I have made an example in fiddle:
http://jsfiddle.net/srs/vF2e9/1/
Sample Code
var directionsDisplay, map;
var directionsService = new google.maps.DirectionsService();
function initialize() {
directionsDisplay = new google.maps.DirectionsRenderer();
var mapOptions = {
zoom: 7,
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: new google.maps.LatLng(41.850033, -87.6500523)
};
map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
directionsDisplay.setMap(map);
calcRoute();
}
function calcRoute() {
var start = "98012";
var end = "98014";
var request = {
origin: start,
destination: end,
travelMode: google.maps.TravelMode.TRANSIT
};
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
var polyLine = new google.maps.Polyline({
strokeColor: '#FF0000'
});
var options = {};
options.directions = response;
options.map = map;
options.polylineOptions = polyLine;
//options.suppressMarkers = true;
directionsDisplay.setOptions(options);// = new google.maps.DirectionsRenderer(options);
polyLine.setMap(map);
//directionsDisplay.setDirections(response);
}
});
}
A polylineOptions anonymous object is not (and shouldn't be) a google.maps.Polyline.
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
var polyLineOptions = {
strokeColor: '#FF0000'
};
var options = {};
options.directions = response;
options.map = map;
options.polylineOptions = polyLineOptions;
//options.suppressMarkers = true;
directionsDisplay.setOptions(options);// = new google.maps.DirectionsRenderer(options);
polyLine.setMap(map);
//directionsDisplay.setDirections(response);
}
});

Hi i'm wanting to create a map that, when a function is called, generates directions to a point based on the users current geolocation. I have tried to do this and so far my attepts have been fruitless, here is my current JS code:
var directionDisplay;
var directionsService = new google.maps.DirectionsService();
var map;
var start = latlon;
var end = "Darwin, NSW, Australia";
var request =
{
origin:start,
destination:end,
travelMode: google.maps.DirectionsTravelMode.DRIVIN
};
function initialize()
{
if (navigator.geolocation)
{
navigator.geolocation.getCurrentPosition(showPosition);
}
function showPosition(position)
{
directionsDisplay = new google.maps.DirectionsRenderer();
var latlon = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
var mapOptions =
{
zoom:15,
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: latlon
}
map = new google.maps.Map(document.getElementById('map_canvas'), mapOptions);
directionsDisplay.setMap(map);
}
}
function getdirections()
{
directionsService.route(request, function(response, status)
{
if (status == google.maps.DirectionsStatus.OK)
{
directionsDisplay.setDirections(response);
}
});
}
Any Help would be greatly appreciated, but keep in mind it must use the google maps api, v3. Thank you :)
Please checkout this jsfiddle,
Here i have hard-coded the starting position and end position is the users current position.
Is this what you are looking for ?
