Google Maps API - Find Coordinates For Several Addresses At A Time
Aug 27, 2010
I'm attempting to find coordinates for several addresses at a time. I'm using a for-loop to loop through an array of addresses. I figured it would be best to have a separate function to evaluate the coordinate given an address, and just call it in every loop.
Note that my code below is simplified (I removed the for loop because that's not where I'm having trouble). I know that the issue is probably because I'm trying to return a value from an anonymous function... I tried making the variable global, I tried having a return line from within the anonymous function, nothing has worked... any tips?
Code follows

i have to draw a line between to different coordinates which are going on google maps so for example :
[Code]...
the above coordinates are in xml format which, i later call in Java script functions and display them on the map as a simple pointers what i need is from one point of coordinates to another point of coordinates Java script would draw a line which would represent the direction from one coordinate to other .

I need a hand with my google maps code Basically what I want to do is display multiple addresses on a single map. I've got that part to work but I need to set-up the bounds and zoom so it zooms out/in and shows all the addresses in the map window...
My problem is after I run the setMapMarker() function in the load() function, I need to pull out the latitude and longitude from the geocoder that is run in the setMapMarker() function... however I can't seem to get it to return those details because the coordinates are pulled in the geocoder function.

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(

I am having some issues with getting multiple sets of coordinates to appear on google maps on my website. I have many items stored in a database, and each row has a field for latitude and a field for longitude. I get the data like this:
$getdeals = "SELECT * FROM deals WHERE cityid='$cityid'";
$result = mysql_query($getdeals);
while($row = mysql_fetch_array($result)){
$title = $row['title'];
$lat = $row['lat'];
$lng = $row['lng'];
//This is where I think I would try to add the point to the map
}

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?
<script type="text/javascript" src="http://maps.google.com/maps/api/js?v=3.2&sensor=false"></script>
In the geocoding portion:

Hopefully a really quick question. I'm a JS novice, and am looking for a way to output the coordinates of a Google maps marker into the value of two text fields, one for latitude and one for longitude.The code below is a simple location search which returns a result with a draggable marker. Currently, the coordinates in both text fields update when the location search is performed, but not when the marker is dragged to a new location afterwards.

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 have seen examples where it shows the google map and you can draw the polygon, but does anyone know if there is a pre existing script that allows someone to make the polygon and populate a form of the coordinates when they are done?Basically what Im trying to do is have a person draw an area on the google map and then save those coordinates for later use.

Are there javascript functions to find the cursor position of a mouse? Also, are there javascript functions to find if the mouse cursor is within a listbox? A C# code sample is shown below:
Listbox lb; //lb is a listbox
Point cpos = lb.PointToClient(Cursor.Position); //find coordinates of mouse
if(lb.ClientRectangle.Contains(cpos)) //if mouse cursor is within the listbox
Are there any javascript functions which can do the same as the above c# methods?

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):

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 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?

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.
