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 .

Fusion Table - Heat Map Layer

    In continuation with the previous example on Fusion Table, we will have a look at another Fusion Table layer example. Today's point of discussion is heat map! What is a heat map? A heat map is geographical representation of data where the values taken by a variable in two-dimensional map are represented as colors. Higher the value of the variable, that place on the map would be represented with a deeper color.     This example is very much similar to the previous one, just for one minor change! Let us have a look at the code.     I have just used a readily available Google Fusion Table for this example. Any anomalies in the data is not my responsibility! Copy the above code in an html file and open it in your browser! You will see the fusion table heat map layer in action! The only change in this code from the previous one is that, the heatmap property of the fusion table layer is made true! The output of the above code looks as s...

Where on Google Map was Osama bin Laden?

                It took years of intelligence gathering and months of following leads and planning an attack for the US to track down the world’s most wanted criminal – Osama bin Laden to a compound in the normally quite city of Abottabad in Pakistan. Since the night when US President Barack Obama announced the terrorist’s death, the Internet has been buzzing with attempts by people all around the globe to pin- point the exact location of the compound on a map.                 Bin Laden's compound had been pinned in multiple different locations on Google Maps and Google Earth by users of Google's Map Marker web app, in various spots across Abbottabad. However, none were accurate and exact. Thanks to photos and diagrams released by the U.S. Dept. of Defense on Monday, Osama bin Laden’s Hideout Compound is now embedded in Google Maps and ...

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...
