Only information bubbles...

         After displaying markers and markers with info windows, we will now display only info windows on the map. So our aim becomes, placing an info window on a google map when a user clicks on the map.

         Now, the first question that will pop up in your mind is why do we need such a thing? To answer this question let us consider a simple example. Consider that, when an user clicks on a map, a marker appears with an info window and you want the user to enter some data in a form in the info window and save that data. Now, if the user enters inconsistent data, there would be marker on the map, having no valid information! The marker would then be rendered useless, with no information! Something like a dangling pointer!

          Now, if you haven't understood a word of this; don't worry. You will soon understand the importance of this example! So, without any further discussions, let's have a look at the code!

          Here goes the code...

<html>
<head>
<title>
Google Maps API v3 - Simple Info window example
</title>
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false">
</script>
<script type="text/javascript">
var map;
function click_window()
{
             map = new google.maps.Map(document.getElementById("map"),
             {
                         zoom: 5,
                         center: new google.maps.LatLng(22.7964,79.5410),
                         mapTypeId: google.maps.MapTypeId.ROADMAP
             });

             var html = "This is an Info window without a marker.";

             var infowindow = new google.maps.InfoWindow(
             {
                         content: html
             });

             google.maps.event.addListener(map, 'click', function(event)
             {
                         infowindow.setPosition(event.latLng);
                         infowindow.open(map);
              });
}
</script>
</head>
<body onload="click_window()" onunload="GUnload()">
<div id="map" style="width: 100%; height: 100%">
</div>
</body>
</html>


           Copy and paste the above code in an html file and see the map in action! The output will look as seen in the picture below.

Google Map within an image

    Hope you'll enjoyed the last post describing how two maps can be placed side-by-side on the same webpage ! Most of you'll will enjoy today's code example too! All of you out there who work on Google Maps API, must have visited the API home page several times! You must have seen the map within the Google Nexus Phone frame there! It appears as though there is a map visible on the mobile screen! One of friend asked me the other day if I could implement that, and I did it and here is the code that I am sharing with you all!     I have used an I-Pad frame and am displaying a map centered at India within it! Here is the code!     The output of the above code is as seen in the result section above! The map that is appearing within the frame is not just an image but can be dragged like any other Google Map! Enjoy the code. It is very simple to understand!     In case you have any queries regarding the same, feel free to le...

Retriving co-ordinates...

         We have seen 2 Google Maps API v3 examples wherein we have retrieved the latitude-longitude co-ordinates of the point of click on the map. In the first example we have displayed the co-ordinates in the information window and in the second , we have displayed the co-ordinates in a form in the information window.         Today we will create a code to retrieve the latitude longitude co-ordinates in a text box while simultaneously a marker appears on the map as well. So, here goes the code. <html> <head> <title> Google Maps API v3 - Adding marker on Click and retrieving the co-ordinates in a text box </title> <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> <script type="text/javascript"> var map;    //When using event as a parameter to a function declare map, strictly as a global variable fun...

Two maps on the same page - Side-by-side

    How good I am feeling to post a code example after such a long time! It's been all "news" over the past so many posts! Well now that I am finally doing a code example, I am posting a very highly requested code sample. Placing two Google Maps on the same page (Now that's simple you would say!), but side by side. Now this is the thing that most people struggle with. Well, implementing the second part is also very simple, as you will see in today's code.     Let's see the code. Here it is!     The output of the above code will be as seen in the result section above.     As most of you will realize, there are two maps, one centered at "Pune" and other at "Noida". Why I chose these two locations? Well, just like that!...The main issue of concern is how the maps appeared side-by-side and not one below the other as would be normal behavior of two "div" elements used in the same page. Now here is the trick! Check out the...
