### 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-role="page" and an id associated with it. Each page is required to have a unique id which is used to link these pages together. When a link is clicked, the Jquery Mobile framework will look for an internal page with that id and transition the page into view. Another thing to remember is that the id attribute of all your elements must be not only unique on a given page, but also unique across the pages in a site. This is because jQuery Mobile's single-page navigation model allows many different "pages" to be present in the DOM at the same time. This also applies when using the multi-page template, since all the "pages" on the template are loaded at the same time.

UPDATE: The following example makes use of the next stable version of Jquery Mobile 1.3.1

Hope the single page and multi-page jQuery mobile structures are clear. However, there is a small problem with the multi-page structure approach that you might face while implementing it. How to have a different page title for all the pages that are stacked in one single HTML? There is a simple solution to this which JQuery Mobile has provided us with and we will discuss it in the next post.

Hope you followed this post and it has helped you. Stay tuned for more such code samples and snippets.

### 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…

### 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…

### Retriving co-ordinates...

We have seen 2 Google Maps API v3 examples wherein we have retrieved the latitude-longitude co-ordinates of the point of click on the map. In the first example we have displayed the co-ordinates in the information window and in the second, we have displayed the co-ordinates in a form in the information window.

Today we will create a code to retrieve the latitude longitude co-ordinates in a text box while simultaneously a marker appears on the map as well. So, here goes the code.
