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.

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 .

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...

Form info window

         Today we will look at a Google Maps API v3 example to add a form in the information bubble! This is usually required when we wish to accept some data/information from the user! This data can be saved to a server in the form of an XML file or a database! The information can then be retrieved back at a later stage, when necessary!          In this example we will only look at form in the information bubble! The connectivity part with the server will be discussed in another post! So, today's code snippet is as seen below! <html> <head> <title> Google Maps API v3 - Adding marker and info window on Click and creating a form in the infowindow with the lat-lng information in it. </title> <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> <script type="text/javascript"> var map;    //When using ev...

The Street View Army

    Google's Street Views have caused controversy more often than not. Sometimes for privacy issues, sometimes for security reasons. But whatever the media has to say, we can't deny the fact that Google Street Views has brought the entire world at your finger tips. You can visit places that you would not be able to visit ever. You can walk the roads, that you had only imagined of treading. You can experience for yourself, various cultures, events, religions and lives of people across the globe all at the comfort of your home. You can visit the deserts, the snow clad mountains, the giant rivers or the gushing waterfalls. Today, let's take a look at the efforts Google is taking to capture the world for us. Google Street View Car     Aha! We all know this vehical. More popular than the Mercs and the BMWs, this street view car has roamed the streets of many a cities since May 25, 2007. Street Views started out as an experimental project with a SUV pac...

Ground Truth - How Google Builds Maps

    Todays's article is cross posted from The Atlantic 's Tech section. The article was posted by Alexis Madrigal who is a senior editor at The Atlantic , where he oversees the Technology channel. So, thanks to The Atlantic and Alexis Madrigal, we will have an exclusive look inside Ground Truth , the secretive program to build the world's best accurate maps.     Behind every Google Map, there is a much more complex map that's the key to your queries but hidden from your view. The deep map contains the logic of places: their no-left-turns and freeway on-ramps, speed limits and traffic conditions. This is the data that you're drawing from when you ask Google to navigate you from point A to point B -- and last week, Google showed me the internal map and demonstrated how it was built. It's the first time the company has let anyone watch how the project it calls GT, or "Ground Truth," actually works.     Google opened up at a key moment in its evo...
