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 .

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...

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...

Jquery Mobile Toolbars - Header and Footer

    In Jquery Mobile there are 2 standard types of toolbars: Header and Footer. The header is typically the first element inside a mobile web page and the footer is typically the last. Both these toolbars usually contain buttons, links and text. In this post today, we will take a look at these 2 toolbars in Jquery Mobile. Lets's take a look at the code below.     As you can see in the HTML above, the structure clearly shows that we have the header as the first element of the Jquery Mobile page and the footer as the last element of the page. The title text is normally an H1 heading element but it's possible to use any heading level (H1-H6) to allow for semantic flexibility. For example, a page containing multiple mobile "pages" may use a H1 element on the home "page" and a H2 element on the secondary pages. All heading levels are styled identically by default to maintain visual consistency as you can see in the above example, we have used H3.    ...

Jquery Mobile - Multi-page structure

    In this post today, we will have a look at the multi-page Jquery mobile architecture. We have discussed the single page architecture in detail in the previous post . In case you have missed it, I recommend you to have a look at it first, before you proceed to the Jquery Mobile Multi-page architecture.     Jquery multi-page architecture is nothing but a collection of DIVs stacked together in a single HTML page linked to each other using the div IDs. Let's take a look at the example below and then discuss it in detail.  The example shows a three "page" site built with 3 jQuery Mobile divs navigated by linking to an id placed on each page wrapper. Note that the id's on the page wrappers are only needed to support the internal page linking, and are optional if each page is a separate HTML document. Here is what three pages look inside the  body  element.     You must have observed that each of the page div has an attribute data-r...
