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.

Now, let's see how we can add buttons to these toolbars. We will add 2 buttons in the header - the back button and another options button. In the footer we will just add a single button. Adding the buttons to the header and footer varies slightly. Let's take a look at the example below.

jQuery Mobile has a feature to automatically create and append "back" buttons to any header, though it is disabled by default. If you use the attribute data-rel="back" on an anchor, any clicks on that anchor will mimic the back button, going back one history entry and ignoring the anchor's default href. This is particularly useful when linking back to a named page, such as a link that says "home", or when generating "back" buttons with JavaScript, such as a button to close a dialog. The header plugin looks for its immediate children and automatically sets the first link button the extreme left of the header and the next link button to the extreme right. So in the above example you will see the "Back" button aligned to the left and the "Options" button aligned to the right.

Adding buttons to the footer is a little tricky. Any link or valid button markup added to the footer will automatically be turned into a button. To save space the buttons in the toolbars are set to inline styling so that the button is only as wide as the text and the icons in it. To include padding on the bar, we will be required to add a class "ui-bar" to the footer. You can try removing the class from the footer in the above example to see the results for yourself.

With this we conclude our discussion on Jquery Mobile header and footer toolbars. Hope you have followed the code samples and hope this tutorial helps you use toolbars more effectively in your Jquery Mobile projects. There is a comprehensive list of examples that you might find exciting and helpful. Do leave a comment and share your thoughts.

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…

Onclick polygon

Yesterday we had a look at a simple polygon example. But that example was not exciting as it was all hard-coded with no user interaction and which means no fun! Today's example will deal with creating a polygon on the fly, i.e. an on-click polygon in action!

The code for creating a polygon is very much similar to creating a polyline! The only difference is that you need to replace "Polyline" by "Polygon" in such examples. Let's head on to our code.

The output of the above code can be viewed in the result section above. If you have any doubts or queries regarding the above code then please comment here or feel free to drop me a mail! Till then, happy mapping!

Get directions between different states in India

Having seen a simple hard coded directions example yesterday, today we will have a look at another simple example but not an hard coded one. In today's  example we will see the directions between different states in India. We have two simple list boxes stating Origin and Destination as lists of the states in India. You can select a state from either of the lists and then you will get the directions between the two selected cities.

If you see yesterday's code and today's code you will find a lot of similarities and so  it would be easy to follow. The code will look lengthy, but it is just because of the list boxes code. So don't worry about the code, just go for it.

The output of the above code will look as seen in the results section above. Hope you find this code helpful in understanding the directions services even further. Tomorrow, we will look at another - a bit complex example. Till then, happy mapping.
Note: The above code will not display any results …

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
