Jquery Mobile Form - Flip toggle switch control

    A binary flip switch is a very common UI element in the mobile web world and was made popular by our very own iOS. This flip switch is used mostly for binary on/off or true/false data inputs. To create a flip switch or a toggle switch, start with a select with data-attribute="slider" and two options. Jquery Mobile would style this select as a regular flip switch with capsule corners and a a circular handle which can be either dragged from one end to the other or tap either sides of the switch.

    The flip toggle switch is available in 2 flavors/sizes - regular and mini. Adding a data attribute data-mini="true" to the input tag renders a smaller sized flip switch. Let's take a look at the code sample below to understand the working in a better way.

    In the code above, you will see 4 different implementations of the flip switch. The first one is a regular flip switch with the label and the toggle button one below the other. The second implementation is exactly similar to the first implementation with the only difference of the added data attribute "data-mini="true"" which reduces the size (basically height) of the flip switch.

    The third implementation gets the label and the slider on the same line. This implementation is done using a div with data attribute data-role="fieldcontain" around the label and select tags. This div has to be within a form tag. Maintaining the HTML structure is very important when using JQuery Mobile framework. To disable the input field just add the keyword "disabled" to the input tag and your input type would be disabled.

     Since this flip switch is nothing but a select with two options, we can make either one of the options selected by default by just writing "selected" for that particular option in the select. This can be seen in the code above, where the last last flip switch is disabled and is "ON"

    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 the range input type effectively to create the range slider in your next Jquery Mobile based application.

Jquery Mobile Listview enhancements and customization

    In this post today, we will take a look at the various enhancements and customization that we can do to the standard listviews. All these enhancements or customization are questions asked by various people on the Jquery Mobile forum. I have tried to put together a solution to some of them.     Let's take a look at a few of them. Some questions are really amazing like " W hen i have 3 nested listview structure and moved to 3rd nested, how to move back to second nested listview? " Now this is a really good question and a nice valid requirement too. When we had see an example on nested listviews  you must have wondered how we would navigate to the previous levels from the current level. Well here is a solution that I had put together.     Another really nice question was " Listview with collapsable listview inside ". This is really a good example to try out. Take a look at the solution that was proposed and also taken from other jsfid...

SASS: Syntactically Awesome Stylesheets - An Introduction

    I had some free time today, and decided to explore into SASS, which I had planned on doing for a long time. SASS is really cool and it really is simple styling with a lot of attitude. SASS really makes CSS so much fun. I loved it and am putting up a few posts to talk about the various features of SASS.     SASS is an extension of CSS3, adding nested rules, variables, mixins, selector inheritance and much more. The SASS CSS is required to be compiled before it is transformed into standard CSS using a command line tool or a web-framework plugin. Let's not worry about this for now.     SASS CSS can be written using 2 types of syntaxes. The most popularly used syntax is known as "SCSS", rightly named " Sassy CSS" and is a superset of CSS3's syntax. This means that every CSS3 stylesheet is valid SCSS as well. The second syntax is an older one known as the "indented syntax" or just SASS. This syntax is for people who do not love brackets and...

Multiple markers...

            It rarely happens that there is just one point of interest or just one location that you would like to mark! Generally there is a bunch of markers that appear on the map! Specifically, you want a list of latitude and longitude pairs representing the points of the markers you'll plot.             To store the list of points, you can combine the power of Javascript's array and object constructs. An array stores a list of numbered entities. To access the elements of the array, you must use their numeric indices. So array[0] will point to the first element in the array while array[n] will point to the nth element in the array.             I will use the following piece of Javascript code to demonstrate how multiple markers can be made to appear on a map using the array structure and the for loop for iteration....

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...

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 a...
