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.

Two maps on the same page - Side-by-side

How good I am feeling to post a code example after such a long time! It's been all "news" over the past so many posts! Well now that I am finally doing a code example, I am posting a very highly requested code sample. Placing two Google Maps on the same page (Now that's simple you would say!), but side by side. Now this is the thing that most people struggle with. Well, implementing the second part is also very simple, as you will see in today's code.

Let's see the code. Here it is!

The output of the above code will be as seen in the result section above.

As most of you will realize, there are two maps, one centered at "Pune" and other at "Noida". Why I chose these two locations? Well, just like that!...The main issue of concern is how the maps appeared side-by-side and not one below the other as would be normal behavior of two "div" elements used in the same page. Now here is the trick! Check out the the first

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 and not …

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 also…

Difference between word-break: break-all versus word-wrap: break-word

The 2 CSS properties word-break: break-all and word-wrap: break-word appear to work in the same way or generate the same output, but there is a slight difference between the 2 and we will be discussing these differences today.

Take a look at the example above. The difference is quite evident, however I will try to explain it further.

word-break: break-all Irrespective of whether it’s a continuous word or many words, break-all breaks them up at the edge of the width limit even within the characters of the same word
word-wrap: break-word This will wrap long words onto the next line.break-word adjusts different words so that they do not break in the middle.
So if you have many fixed-size spans which get content dynamically, you might just prefer using word-wrap: break-word, as that way only the continuous words are broken in between, and in case it’s a sentence comprising many words, the spaces are adjusted to get intact words (no break within a word).     In case you want to exp…
