Jquery Mobile - Filtering the Listview

    So you have a very long list of items and you want to provide the users with a searching facility. There is nothing to worry here. Jquery Mobile provides a very simple solution to a very difficult and time-comsuming looking problem. jQuery Mobile provides a very easy way to filter a list with a simple client-side search feature. To make a list filterable, simply add the data-filter="true" attribute to the list. The framework will then append a search box above the list and add the behavior to filter out list items that don't contain the current search string as the user types. The input's placeholder text defaults to "Filter items...".

    Now again, this is not going to satisfy the client. The client will not like the default search and will ask for customization. No problem again. We can do it very easily again by virtue of the Jquery Mobile framework. To configure the placeholder text in the search input, use the data attribute "data-filter-placeholder" on your listview. By default the search box inherits its theme from its parent. The search box theme too can be configured using the data attribute "data-filter-theme" on your listview. So now you have a customized filterable listview.

    Following is a simple example of how the search works with the listview. Hope you have follow the example here. Do drop a comment in case you have any doubt or want to see something more in this post or on the blog in general.

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...

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...

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....

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...
