I'm new to the Google Maps v3 API and was wondering if there's a way to display waypoints with different markers when you're building directions, for example:
function calcRoute() {
var request = {
origin: "Sydney, NSW",
destination: "Sydney, NSW",
waypoints:[{location: "Bourke, NSW"}, {location: "Broken Hill, NSW"}],
travelMode: google.maps.TravelMode.DRIVING
};
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
}
});
}
So to phrase my question in another way, is there a way to make the waypoints appear as white dots and the origin/destination as Google's green markers?
Thanks in advance for any help!
There is no implemented option to use different markers for waypoints.
You must set the suppressMarkers-option of the directionsRenderer to false(no markers will be rendered) , parse the directionsResult and create the desired markers on your own.

I have am displaying 2000 markers on google maps. I notice the performance is a little slow. What I am not sure about... is it it slow because if the number of markers added to the map or visibility? How do I improve the performance? Can I just add them to the map and "hide" markers outside of bounds? Would that help or would it not because even though its not visible, its added to the map? The data to show the markers is in an list called var datapoints = [...].
My code to add markers is like this:
for (i = 0; i < markers.length; i++) {
var data = markers[i]
var myLatlng = new google.maps.LatLng(data.lat, data.lng);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: data.title
});
(function (marker, data) {
google.maps.event.addListener(marker, "click", function (e) {
infoWindow.setContent(data.description);
infoWindow.open(map, marker);
});
})(marker, data);
}
Any optimization recommendations appreciated!
You have a few options here. Google's docs suggest either limiting visible markers to the current viewport, clustering (distance or grid based), or fusion tables. I've implemented google maps with a customization of the MarkerClusterer module that works quite well for large amounts of markers on one map. Best of luck!
I have requirement of displaying an address on a click of a button, for which i got the latitude and longitude of the desired location,
while mapping in URl
https://maps.google.com/?ll=28.64036031970850,77.24250191970849
like this. I don't get the desire pointer on google map Like which we get A in red pointer.
Thanks for any assistance.
Try this. Change the lat/long as per your need.
https://maps.google.com/?q=22.917923,72.773438
You can use custom markers for this. Here is a snippet to get you started:
// Create the map
var map = new google.maps.Map($("#map-result"), mapOptions);
// Create the marker on the map
var marker = new CustomMarker(new google.maps.LatLng(pinLatitude, pinLongitude), map, searchResults[i], markerNumber);
// Add listener to react to click of marker
google.maps.event.addListener(marker, 'click', (function (marker, i) {
return function () {
// Call some function to do something
showSelectedMarker();
}
})(marker, i));
A very good example is here:
Google Maps JS API v3 - Simple Multiple Marker Example
Set Sencha Touch Map Location
Hi All, I am trying to simply set the Sencha Touch 2 map object to a specific zipcode. I an setting the config to to {useCurrentLoction: true} which works fine but after hours of research I can't seem to find a way to tell the map object to reposition to another city, or address or specifically a zipcode somewhere else in the US.
It looks like the Google API has these features but this include:
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=true"></script>
Doesn't recognize the api calls that Google is using in their docs. Google says to get am API access key but this needs to run from multiple locations so I was hoping to achieve this without needing to get a key.
Has anyone been able to reposition the Sencha Touch 2 map object with the API accessed by the above (maps.google.com/maps/api/js?sensor=true) ?
Thanks!
Just include <script src="http://maps.google.com/maps/api/js?sensor=true"></script> in your HTML file
Then in your view create a xtype map, and then in the listener add an event painted like this:
listeners:
{
painted: function( component, eOpts ) {
console.log("Entered paint");
gotoAddress();
var map = Ext.getCmp('mymap');
map.setMapCenter(addr);
}
}
// Location function add the parameter as desired address to navigate.
// This also includes showing mapper and info window
function gotoAddress() {
var address = "enter the address required";
var map = Ext.getCmp('mymap');
var geocoder = new google.maps.Geocoder();
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
addr= results[0].geometry.location;
map.setMapCenter(results[0].geometry.location);
marker.setMap(map.getMap());
marker.setPosition(results[0].geometry.location);
infowindow.setContent(address);
infowindow.open(map.getMap(),marker);
} else {
alert('Sorry Address could not be traced: ' + status);
}
});
}
Note: Paint is the event that gets called every time you navigate to page where you have used the map. Initialize event will be created only once when you create this page.
this has been baking my noodle for months, I'll be honest, I am a designer not a programmer so this type of scripting is a bit harder than the average jquery/javascript that I'm used too.
I can't find any basic documentation on how to implement it, apart from this but it's not massively intuitive - http://jquery-ui-map.googlecode.com/svn/trunk/demos/jquery-mobile-example.html
I've tried making a JSfiddle, but I can't even get it to work (now working thanks to Tsar)
I've built a jQuery mobile app and I'm desperate to get the geo-location functionality working with fusion table markers (from my fusion table) and to be allowed to click on the fusion table markers to reveal a info window. This info window will be constructed in fusion tables.
I need the geo-location to center the map on the devices current location - if the geo-location is not available or denied by device user, then the map needs to be centered on these co-ordinates 52.450939, -1.721002.
What would be the next level is to have the the jQuery mobile UI pop-up window but this is not critical, just the standard bubble on the map is fine.
A updated JSFiddle... http://jsfiddle.net/twGHC/30/
My fusion table number is: 1260763
Default location is: (only if Geo location is not available) 52.450939, -1.721002
Zoom level: 13
Any advice would be awesome, please feel free to JSfiddle it. Thanks in advance.
Here's a working solution, which detects user's location, drops a marker on it and plots the map with your Fusion Markers. As per Google Maps v3 API documentation:
$(function() {
var position = new google.maps.LatLng(52.450939, -1.721002);
getCurrentPosition = function(callback) {
// Try W3C Geolocation (Preferred)
if(navigator.geolocation) {
navigator.geolocation.getCurrentPosition(
function(pos) {
position = new google.maps.LatLng(pos.coords.latitude, pos.coords.longitude);
callback(position);
}, callback(position));
} // Try Google Gears Geolocation
else if (google.gears) {
var geo = google.gears.factory.create('beta.geolocation');
geo.getCurrentPosition(
function(pos) {
position = new google.maps.LatLng(pos.latitude,pos.longitude);
callback(position);
}, callback(position));
} // Browser doesn't support Geolocation
else {
// Drop the user off in Coventry =)
callback(position);
}
};
// call the above function
getCurrentPosition(InitMap);
});
function InitMap(pos) {
map = new google.maps.Map(document.getElementById('map_canvas'), {
center: pos,
zoom: 14,
mapTypeId: 'roadmap'
});
var marker = new google.maps.Marker({
position: pos,
animation: google.maps.Animation.DROP,
map: map,
title: "You are here, mate!"
});
var layer = new google.maps.FusionTablesLayer({
query: {
select: 'Geocodable address',
from: '1260763'
},
});
layer.setMap(map);
};
When user denies tracking of his location, exception is caught in getCurrentPosition, however, 2nd optional parameter in this function is an exception handler, so what I did is simply passed in callback(position) so that default location sets on the map. If you don't want to do it, move out the map initializer code from InitMap into separate function and call it instead, when exceptions are caught, to display a blank map.

P.S. In case your next question is "how to add a balloon pop-up on marker click", here's what you need to do.
Here is how to do it with jquery-ui-map:

If you just want to change within a certain radius of the client position this is how you would do it
http://jsfiddle.net/Ywknf/1/ (client location is the initial point so everyone can see the results)
Here is the code if the url isnt working or the trunk code changed
$(function() {
$('#map_canvas').gmap({'center': '52.450939, -1.721002', 'zoom': 10, 'disableDefaultUI': true, 'mapTypeId': 'terrain'}).bind('init', function(event, map) {
$('#map_canvas').gmap('getCurrentPosition', function(results, status) {
if ( status === 'OK' ) {
var position = new google.maps.LatLng(results.coords.latitude, results.coords.longitude);
var marker = $('#map_canvas').gmap('get', 'markers > client' );
if ( !marker ) {
$('#map_canvas').gmap('addMarker', { 'id': 'client', 'position': position, 'bounds': true });
} else {
marker.setPosition(position);
map.panTo(position);
}
} else if ( status === 'NOT_SUPPORTED' ) {
$('#map_canvas').gmap('addMarker', { 'id': 'client', 'position': $('#map_canvas').gmap('get', 'map').getCenter(), 'bounds': true });
}
});
$('#map_canvas').gmap('loadFusion', { 'query': { 'select': 'Geocodable address', 'from': 1260763 } } );
});
});
I wonder whether someone may be able to help me please.
I've put some coding together (please see below) whereby a user goes onto a HTML form, they type in an address and click a 'Search' button. Upon doing this, the location is plotted on the Google map and the Lat and Long co-oridnates are automatically entered into the associated text boxes on my form.
What I would like to do, if at all possible, is for the marker to be draggable so the user can fine tune the location, and as they drag the marker, I'd like for the Lat and Long fields to change their
associated co-ordinates.
In addition, I'd also like, if at all possible, to have a field on the form called 'NearestAddress' to show the nearest address to where the marker has been dragged to.
I've managed to make the markers draggable but they don't update the Latitude and Longitude text boxes. I'm also unsure how to add the functionality to show the updated address to where the marker has been dragged to.
(function() {
// Defining some global variables
var map, geocoder, myMarker, infowindow;
window.onload = function() {
// Creating a new map
var options = {
zoom: 3,
center: new google.maps.LatLng(55.378051,-3.435973),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map'), options);
// Getting a reference to the HTML form
var form = document.getElementById('LocationSearchForm');
// Catching the forms submit event
form.onsubmit = function() {
// Getting the address from the text input
var address = document.getElementById('Address').value;
// Making the Geocoder call
getCoordinates(address);
// Preventing the form from doing a page submit
return false;
}
}
// Create a function the will return the coordinates for the address
function getCoordinates(address) {
// Check to see if we already have a geocoded object. If not we create one
if(!geocoder) {
geocoder = new google.maps.Geocoder();
}
// Creating a GeocoderRequest object
var geocoderRequest = {
address: address
}
// Making the Geocode request
geocoder.geocode(geocoderRequest, function(results, status) {
// Check if status is OK before proceeding
if (status == google.maps.GeocoderStatus.OK) {
// Center the map on the returned location
map.setCenter(results[0].geometry.location);
// Creating a new marker and adding it to the map
var myMarker = new google.maps.Marker({
map: map,
position: results[0].geometry.location,
draggable:true
});
document.getElementById('Latitude').value= results[0].geometry.location.lat();
document.getElementById('Longitude').value= results[0].geometry.location.lng();
google.maps.event.addListener(myMarker, 'dragend', function(evt){
document.getElementById('current').innerHTML = '<p>Marker dropped: Current Lat: ' + evt.latLng.lat().toFixed(3) + ' Current Lng: ' + evt.latLng.lng().toFixed(3) + '</p>';
});
google.maps.event.addListener(myMarker, 'dragstart', function(evt){
document.getElementById('current').innerHTML = '<p>Currently dragging marker...</p>';
});
map.setCenter(myMarker.position);
myMarker.setMap(map);
}
});
}
})();
I am new to Google maps development and I'm not even sure whether it's possible to achieve what I want. I've been working on this now for a few weeks and it's driving me a little crazy, so if someone could perhaps point me in the right direction it would gratefully be received.
Many thanks and kind regards
Chris
Instead of evt.latLng.lat().toFixed(3) you should just use the myMarker object and grab it's position.
Getting the nearest address is not that easy, but requires reverse geocoding, and to be honest I don't see the point in doing it. You would have to make special cases for the occurences where there couldn't be found a closest address and stuff like that.
If you really want to do it though there is a webservice you can call to do it.
