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.

Side-scrolling web pages issue with Jquery Mobile - Issue #5748

    While developing a Jquery mobile based application, I came across a issue that is observed only on the iOS 6 devices and Android 4.2.2 devices.     What is the issue?         Web pages are side scrolling on iOS6 and Android 4.2.2 devices.     How did I debug the issue?         This bug was in our applications bug tracker for a long time and since I am the lone front-end developer the project that I am working on, my manger was pushing me to close this bug quickly. I had used the perfect mobile meta tag and still the web pages were side-scrolling. None of my divs had width that was going beyond the device widths and still there was this issue. That day, I decided to break down my HTML to pieces, and tested each piece on the dreadful iOS 6 device. I came down to a textbox that had some placeholder text in it and there it was, the issue was glaring me in my face. ...

Punjab cities to implement GIS...

            The Punjab government is all set to implement ultra modern GIS systems in 6 big cities of Punjab namely Amritsar, Ludhiana, Jalandhar, Patiala, Batinda and Pathakot to facilitate future planning, expansion and maintenance of civic infrastructure in these cities. The GIS will be implemented in these cities by October 31, 2011, which would be further implemented in other districts of the state.             Complete information of these cities will be available on the GIS which should prove beneficial and helpful during the preparation of "Master Plans" of these cities in the future. The satellite images of these cities will be taken which would later on be developed to form a large database. The maps that will be generated would provide detailed information on roads and rail networking along with exact locations of bus stops and railway stations. The maps will also s...

SASS: Syntactically Awesome Stylesheets - An Introduction

    I had some free time today, and decided to explore into SASS, which I had planned on doing for a long time. SASS is really cool and it really is simple styling with a lot of attitude. SASS really makes CSS so much fun. I loved it and am putting up a few posts to talk about the various features of SASS.     SASS is an extension of CSS3, adding nested rules, variables, mixins, selector inheritance and much more. The SASS CSS is required to be compiled before it is transformed into standard CSS using a command line tool or a web-framework plugin. Let's not worry about this for now.     SASS CSS can be written using 2 types of syntaxes. The most popularly used syntax is known as "SCSS", rightly named " Sassy CSS" and is a superset of CSS3's syntax. This means that every CSS3 stylesheet is valid SCSS as well. The second syntax is an older one known as the "indented syntax" or just SASS. This syntax is for people who do not love brackets and...

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...
