Changing The Icon On Google Maps?
Jan 8, 2010
I have the following code to insert a google map of the UK into my page with some markers on it. This is fine except I want to change the icon to a simple flat spot. I'm sure this is easy and I have actually managed this before when there was only one marker on the map. how to do it on this example though.

We got a google maps with a bunch of pins. Each pin is setup to use our blue custom icon image. I'm trying to make it so that when you click on a pin, that particular pin changes to a green version of the icon, and all the reset stay blue. If the user clicks another pin, it turns green and the previous goes back to blue.Basicly only the clicked active pin should be green.
google.maps.event.addListener(markers[indx], 'click', function() {
this.setIcon("/images/greenmarker.png");
});
Here is my code so far that will change the clicked pin into a green version.My problem is all attempts to change all pins back to blue prior to changing this clicked pin to green fails bad.

I search through the forums and google but didn't find anything on this, but I was wondering if anyone was having or has had issues with google maps changing their lat/long coordinates, even when a frozen version is declared?

In the geocoding portion:

I want to have several maps on my aspx/ascx-Webpage, but only the last one is rendered after PageLoad(). Is there any limitation for that in the goMap() plugin?

I'm developing a land use map and want to use Google Maps. Just want to ask if the Javascript API could actually handle overlays like this sample: URl...Or you would suggest other ways to do this?

I'm not sure where I have translated this incorrectly. I have one google map embedded on my page which works fine. But I wanted to add a second one. I thought the easiest way to do this would be to have a second page which is called later on with all the details on it for the second map. However although I think (this I presume is where I went wrong) I have replicated the instructions correctly the place holder for the second map just remains blank.
This is the code for my called page with the instructions for the second map:
And this is the script of the main page, just in case I would be better off keeping them both in one place.

I've cut out the script that doesn't relate to this so I hope I haven't missed anything important.

I'm working on a project which implements google Maps. Now I have to choose between GWT or JavaScript as a programming platform. I'm wondering which is faster when accessing the data to be used to initialise the maps from a remote server?

Been looking at google maps, but i am not sure if this is possible, what do you think?
1) Fill database with places (refering to lat + long values) + put markers on google map.
2) Users can then browse the map, click on a marker to select the location which referes to a place in a database.
I know I can add markers to a map. Not sure if it is possible for a user to click one, which then fills a box in a form though.

I am working on creating a map using the google maps API. I would like to update the markers and info windows using an XML database. I know how to parse the XML using PHP if I was just going to create a table on the page, but for the life of me I can't find a complete and simple description of how to do it with javascript. I've been reading tutorials and W3 schools reference for over a week trying to figure it out. I'm new to javascipt, so some of the stuff I don't really understand. I did find a similar question posted on this forum, although I can't get it working. Here is my code (note: this code doesn't work, I know that I'm missing some way to load the xml and parse it, but I don't see how its done):

I am messing around with Google Maps a little and the fundamental difficulty in building anything useful is extrapolating address information from another website. I would like to be able to use a form like yahoo yellow pages send it a zip code and get back a bunch of, say, banks in that zip code and parse the address out. Some things, very few, actually return data in the XML format, but how do you write a script that send a request to a website and then returns that request as a DOM object. I'll even take HTML and then I'll parse it out myself, but how do you do that.
I know it sounds fundamental, but I'm a real beginner in this, so if you can push me in the right direction I would appreciate it too.

I think maybe this is the right thread for it since i found out Google map control can be created using AJAX.
So the question is simple, How to create Google Maps Control ? preferably in an ASP.Net environment.
Found a source code here (GNU licensed)[url]

I've seen several websites using a custom image as a map with google maps controls.I'm familiar with how to use the google maps api in general, but I don't know how to use a custom map image that isn't based on the real world, in other words it will be an image of a map from a video game, so general latitude and longitude wont apply.

I have a boss who wants to show 5000 points on a Google map. So far, only a fraction of this being displayed freezes the browser. I've been challenged to make this possible while still in the realm of the browser. Would the flash version of Google maps api be a better bet? Does flash provide a better framework for this kind of heavy usage?

in my code below, I need to change the linemap.setCenter(new GLatLng(i[0], i[1]), 13); to have the LAT and LONG from my database therefore, I think maybe I need to open a database connection (which I think i am on the same page) and put some ASP in my JavaScript?!

In this snippet the addresses stored in address[] is geocoded using google maps API. The problem comes when i try to pass these values on to the array flightPlanCoordinates to create a polyline. Nothing happens.
Can anyone tell me why? PS. Im quite new to JS
var flightPlanCoordinates = [];
for ( var i=0, len=address.length; i<len; ++i ){
geocoder.geocode( { 'address': address[i]}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
flightPlanCoordinates.push(

What I'm trying to do is import a list of addresses from an xml file and display them in a google map. When each marker is clicked, a window will appear with the address and a name given from the xml. So far, I've gotten the code to work, with one issue.. There has to be an alert box in the for loop (see code) before I use the geocoder. With the alert box, everything shows up as it should, except that I don't need an alert box popping up everytime a marker is added. Doesn't matter what information is in the alert box, as long as it is there, it works.
But, if I take the alert box out, then all the markers will display the same name and address in its info window. The name/address displayed is the last one in my xml file. I thought it just needed the pause so I had tried: setTimeout("alert('');",1000); but that didn't work, even with the alert box within the pause..

I am using the Google Maps API to integrate mapping into a web application. I am using HTML and JavaScript. I am having difficaulty integrating the directions function. I have a form which collects the users address/current location which is supposed to display a set of turn by turn direction and a route on the map when the users submits. I currently have a custom image icon which works perfectly. I cannot figure out why this does not work as i dont not receive any error codes which is very furstrating. Here is my HTML form
<form id="address_form" onsubmit="displayDirections(); return false" action="#" >
<p>
<label for="street">Street Address</label>
<input id="street" name="street_address" type="text" tabindex="1" />
</p>
<p>
<label for="city">City</label>
<input id="city" name="city" type="text" tabindex="2" />

I've written a google maps app for work and have got it all running nicely...in chrome. I've only just noticed that for some reason it's not working in firefox or internet explorer. I was wondering if someone could take a look at the simple extract that I've made and show me where I'm going wrong (If I am):
Javascript:
Code:
function initialize() {
if (GBrowserIsCompatible()) {
//Create a div called map_canvas in the html where the map will be displayed
var map = new GMap2(document.getElementById("map_canvas"));
//Set the map to center on these coordinates
map.setCenter(new GLatLng(55.872759,-4.297972), 15);
[Code]..

i've found out how to find the distance between 2 lat lng points using google's distanceFrom method:
Code:
// NR14 7PZ
var loc1 = new GLatLng(52.5773139, 1.3712427);
// NR32 1TB
var loc2 = new GLatLng(52.4788314, 1.7577444);
alert(loc2.distanceFrom(loc1) / 1000);
However, I'd like to be able to convert a distance to lat lng. The main reason I'm doing this is so that I can figure out the bounds of a certain area of a co-ordinate. For example I specify a point, and then I need to draw a box around this area going x distance North, South, East and West, but until I know how many units make up a kilometre this wont be easy.
I guess I could go to google maps, click on a point and then click on another point and keep doing that until I get exactly 1km away from the original point, then just minus or plus for the lat and lng to find out the unit value for 1km, but I have a feeling that this wont be accurate. Can anyone lend any advice, I realize that what I'm asking is more a map question than a google maps javascript api question, but perhaps someone has come across this before?

Here's the map demo:[URL]... It's a map using clusters for markers, clusters work ok, markers place correctly but no matter what I do I don't seem to get the infoWindows to open. OnClick event for infowindows displays the alert I added (but now it's commented so it does not show). So the onclick funtion works I think? It just does not open the infowindow... Kinda lost here, any help? I've been fighting with this so long I can even consider giving some quid in return for a working solution! (via paypal or so).
