Jquery Mobile Form - Search input

    Input field of type search is newly introduced in HTML5 and is very well styled. The style is further enhanced when using the Jquery Mobile framework and we will see how this can be done in today's post. Jquery Mobile styles the search input type with capsule-corners and adds a 'x' icon to the right end, which clears the text in the search box.

     The seacrch input elements are available in 2 flavors/sizes - regular and mini. Adding a data attribute data-mini="true" to the input tag renders a smaller sized input element. 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 input search element. The first one is a regular input of type search with the label and the searchbox 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 saerchbox.

    The third implementation gets the label and the saerchbox on the same line. This implementation is done using a div with data attribute data-role="fieldcontain" around the label and input tags. This div has to be within a form tag. Maintaining the HTML structure is very important when using JQuery Mobile framework.

    In the fourth implementation, we have used the HTML5 placeholder property and done away with the label completely. However, for the sake of accessibility, we have included the label tag with class="ui-hidden-accessible" so that the label is not displayed but is present in the HTML structure. This implementation is popularly used on mobile sites as this reduces the amount of scroll.

    To disable the input field just add the keyword "disabled" to the input tag and your input type would be disabled.

    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.

    In the next post that follows, we will take a look at how we can customize the search box styling. This would include using custom icons for the the 'magnifying glass' and 'x' icon in the search box and reducing/removing the rounded corners property on the search box.

     Hope this post has been informative to you and helps you use the search input type effectively in your next Jquery Mobile based application. Drop a comment to let me know what you feel about this post as well as the earlier series on Jquery Mobile listview. Share the post if is has helped you, so that maximum developers benefit from this one. Stay tuned for the post on customizing the search box using Jquery Mobile.

Playing with the markers and info window bubbles...

    In the last few posts, we have seen some marker examples and some information window examples. Now, lets do something interesting combining these two things. Just writing that "This is an info window" in the information bubble is not very interesting! And I know this...Have gone through the same phase!     So, today we will do something interesting! We will display the latitude- longitude co-ordinates of the point that the user clicks on the map! Doing this is not at all complex! Copy paste the following code and you will see for yourself a map coming to life!     The output of the above code looks as seen in the result section above! If you have any queries regarding the above code please comment on the blog post or feel free to contact me at my mail ID .

Ground Truth - How Google Builds Maps

    Todays's article is cross posted from The Atlantic 's Tech section. The article was posted by Alexis Madrigal who is a senior editor at The Atlantic , where he oversees the Technology channel. So, thanks to The Atlantic and Alexis Madrigal, we will have an exclusive look inside Ground Truth , the secretive program to build the world's best accurate maps.     Behind every Google Map, there is a much more complex map that's the key to your queries but hidden from your view. The deep map contains the logic of places: their no-left-turns and freeway on-ramps, speed limits and traffic conditions. This is the data that you're drawing from when you ask Google to navigate you from point A to point B -- and last week, Google showed me the internal map and demonstrated how it was built. It's the first time the company has let anyone watch how the project it calls GT, or "Ground Truth," actually works.     Google opened up at a key moment in its evo...

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 spa...

The Bicycling Layer...

    Recreational cyclists and bike commuters alike can plot cycle-friendly routes, find trails, and avoid snarling traffic with Google Map's Bicycle layer. Map's bike-friendly, green-toned map layer is very eye-pleasing. The Google Maps API allows you to add bicycle information to your maps using the BicyclingLayer object.     The BicyclingLayer renders a layer of bike paths, suggested bike routes and other overlays specific to bicycling usage on top of the given map. Additionally, the layer alters the style of the base map itself to emphasize streets supporting bicycle routes and de-emphasize streets inappropriate for bicycles.     Let us have a look at the following example. The code has a map which is centered at Pune, India. There are very few cycle tracks in Pune and so you will see just a few dark green lines on the map. But if you would change the latitude-longitude values in the code and center the map at USA, then you will see a...

Fusion Table Layer...

    Today we will have a look at the "Fusion Table" Layer example. But before we start with the actual code, we will have a look at what Fusion Table is. Google Fusion Table is a free service for sharing and visualizing data online. It allows you to share data, merge data from multiple tables into interesting derived tables, and see the most up-to-date data from all sources. There is a lot of documentation about Google Fusion Table available on the web. You can visit their home page or the Google Research Blog to gather more information about Fusion Tables.     Let us have a look at the following code. The code is very short and simple to understand!     The few things to look out for in the above code are: The manner in which mapTypeId has been specified! In other Google Maps API v3 examples, we have seen that we specify mapTypeID as ROADMAP, SATELLITE, etc. i.e., all the letters are in uppercase and not in quotes! However, in this...
