Google maps api directions zoom not working - javascript

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

Move markers and redraw path with move Google maps

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.

Cordova Device Ready Initialize Google Map

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);

Uncaught TypeError: Cannot read property 'text' of undefined Google Map [duplicate]

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); }
});
}

Google Map API V3. Unable to create custom polyline for TRANSIT directions

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);
}
});

Get directions based on geolocation, google-maps-api

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 ?
