Jquery Mobile Form - Radio buttons

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

    The radio buttons can be used singularly or in a vertical group or can be even grouped horizontally. These radio buttons can be used along with data-mini="true" too, which renders the radio buttons 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 radio buttons 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 radio buttons together giving them the right visual grouping. Using the data-mini="true" attribute with fieldset will render smaller sized radio buttons as seen in the third implementation.

    In the next implementation, we have the label and the radio buttons 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 radio buttons.

    In the next and final implementation of radio buttons we will see how to create a horizontal set of radio buttons. 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-tupe attribute will inform JQM to render the radio buttons 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 radio buttons 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 als...

Google Map's Real-Time Traffic Layer...

    You can now check the traffic condition on the road before you leave for work, or a party or to your friend's place. Google's Traffic layer shows the traffic conditions in your area - LIVE!!! Live traffic data is available in major cities in the United States, France, Britain, Canada and Australia, with new cities and countries frequently added. The Google Maps API allows you to add real-time traffic information (where supported) to your maps using the TrafficLayer object. Traffic information is provided for the time at which the request is made. Consult this spreadsheet to determine traffic coverage support.     Let us now have a look at the Google Maps API - Trafiic Layer example. Copy the following code in a simple text file and save it as html. Click on this html file and it will open in your default browser. You will then see the traffic conditions in your area - LIVE...     The output of the above code looks as seen in the r...

Playing with the markers and info window bubbles...

    In the last few posts, we have seen some marker examples and some information window examples. Now, lets do something interesting combining these two things. Just writing that "This is an info window" in the information bubble is not very interesting! And I know this...Have gone through the same phase!     So, today we will do something interesting! We will display the latitude- longitude co-ordinates of the point that the user clicks on the map! Doing this is not at all complex! Copy paste the following code and you will see for yourself a map coming to life!     The output of the above code looks as seen in the result section above! If you have any queries regarding the above code please comment on the blog post or feel free to contact me at my mail ID .

Web based GIS for polling booths in West Bengal...

         The election commission of India will install web-based GIS in West Bengal's polling booths to help the State Chief Electoral Officer track them on their web site. The system will provide a map showing the exact spatial location of all 51919 polling booths and nearby landmarks, with their latitudinal and longitudinal coordinates. Boundaries of the parliamentary and assembly constituencies of the booths, along with all the administrative boundaries will also be provided in the GIS-based map.          The software will give a 360-degree view of the entire area falling within the 200-meter radius of each polling booth, including approach roads and nearby installations. It will show every detail of the polling station, such as the number of voters, number of polling and security personnel deployed, details about the current law and order situation and reports of past violence or disturbance in the are...

Rail Radar - Map your Train Live!

    Rail Radar - An interactive map that allows users to watch the movements of trains that are currently running in India. This means that you can now know the status of your trains live! Rail Radar is a real time tracker of the Indian Railways passenger trains. This live tracker is shown on our very own Google Maps and this long awaited system is a result of a collaboration between the CRIS - Center for Railway Information System and RailYatri.in.     Since this is a live tracking system of the Indian Railways, a few questions that will pop up in the minds who have ever travelled by railways will be - "Is this system really reliable? Is the data accurate? Can I trust the Rail Radar ?" Well, the system is reliable and you can trust the data since the information and intelligence behind the Rail Radar is extracted and harnessed from volumes of data from the official Indian Railway's train running operational data. With regards to accuracy – this...
