Jquery Mobile Form - Checkboxes

    Checkboxes - popularly used in forms for multi-option selection, pose a problem in the mobile web world! The checkboxes being so small as they are, reduce the touch area and it becomes really difficult for selection. Jquery Mobile styles these checkboxes in such a way that they become touch friendly and gel with their overall framework design. Jquery Mobile styles the label for the checkboxes so that they are larger and clickable. A custom set of icons representing the checkboxes is added to provide additional visual feedback.

    The checkboxes can be used singularly or in a vertical group or can be even grouped horizontally. These checkboxes can be used along with data-mini="true" too, which renders the checkboxes in a smaller size. We will take a look at all this in the example that follows.


    In the first implementation you will see, 3 singular checkboxes which are not attached to each other like in the second implementation. These 2 implementations differ by the usage of the "fieldset" and the data-role="controlgroup". Adding the fieldset with data-role="controlgroup" around the input tags will group the checkboxes together giving them the right visual grouping. Using the data-mini="true" attribute with fieldset will render smaller sized checkboxes as seen in the third implementation.

    In the next implementation, we have the label and the checkboxes control group aligned next to each other. To achieve this you need to wrap your fieldset with dat-role="controlgroup" within a div with data-role="fieldcontain". All of these 4 implementation have a vertical grouping of checkboxes.

    In the next and final implementation of checkboxes we will see how to create a horizontal set of checkboxes  This again is pretty simple like all the above implementations. You need to create a fieldset with data-role="controlgroup" and another data attribute data-type="horizontal". This data-type attribute will inform JQM to render the checkboxes in a horizontal group.

    For the sake of accessibility, jQuery Mobile requires that all form elements be paired with a meaningful label. To hide labels in a way that leaves them visible to assistive technologies. — for example, when letting an element's placeholder attribute serve as a label — apply the helper class ui-hidden-accessible to the label itself. While the label will no longer be visible, it will be available to assisitive technologies such as screen readers.

    Hope this post has been informative to you and helps you use 
checkboxes effectively in your next Jquery Mobile based application.

Where does Google get it's live traffic data from?

Referring to a post that I wrote earlier, Google’s - Live traffic Layer, ever wondered how Google collected this data? I was wondering the other day, how Google received live data to display it on their maps as a layer! I looked up the web and found something very interesting and am sharing the same with you all.As we all know, the traffic layer is available most accurately in several states in USA. Most major metro areas in the US have sensors embedded in their highways. These sensors track real time traffic data. Easy to miss at high speeds (hopefully anyway, traffic permitting), more commonly noticed may be the similar sensors that often exist at many busy intersections that help the traffic lights most efficiently let the most amount of people through. The information from these tracking sensors is reported back to the Department of Transportation (DOT). The DOT uses this data to update some of the digital signs that report traffic conditions in many metro areas. They also…

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 the first

Geodesic Polyline

Today we will have a look at a very interesting polyline example - "The geodesic polyline". Now the first question that will pop is "What is geodesic?". Mathematically, geodesic means the shortest line between two points on a mathematically defined surface, as a straight line on a plain or an arc of a great circle or sphere.

    The next question after reading the above definition is clearly, "Why do we need geodesic polylines?" and that would be followed up with "What is this Great Circle?". We will discuss this first, before we move on to the actual example today. The example is very very similar to the normal polyline example, with just a small change.

    Having said so, I will now try to explain why we need a geodesic polyline? The shortest distance between two locations on the earth is rarely a straight line as the earth is roughly spherical in nature. So any two points on the earth, even if they are very close lie on a curve and not …
