Jquery Mobile Form - Select Menus Part II

    In part II of this tutorial on creating select menus using Jquery Mobile, we will discuss some customization techniques like overriding the default native OS select menu or disabling an option or creating a multi-select select box. It is advisable that you take a look at part I of this tutorial where we have discussed the basics of the select menu. In case you have decided to proceed with this part, then we are ready to take a look at the code that follows.



    In the example code above, you will observe 2 different selects. We will be discussing the following data attributes and HTML5 properties that will enhance the select menus further.

1. data-native-menu="false"
2. data-placeholder="true"
3. disabled
4. multiple

    As seen in the first implementation, by adding the data attribute data-native-menu="false" we can simply override the native OS menu control and display a pop-up containing the options in a listview. If there are a large number of options, the framework will automatically create a new "page" populated with a standard listview for the options.

    To create a placeholder for the select we just need to include a data attribute data-placeholder="true" to an option which holds the placeholder text. This option will then be styled accordingly and will not be selectable. In case you want to disable an option just add disable to that option and that option will be styled as a disabled listview. All the above three things are part of the first implementation in the above example.

    Lets now take a look at how to create a multi select select box. It is as simple as it sounds a big task. Just add keyword multiple to your select element (as seen in the second implementation) and the framework will style each of your option as a listview with a checkbox and you can select multiple options. Each of the options selected will be populated as comma seperated list on the custom select button. To top this off Jquery Mobile framework will aslo add a count bubble on the select button indicating how many options are selected.

    Hope you have enjoyed this post and the other form elements tutorials. Drop a line in case this has helped you, or if you have any concerns, comments on the post or the series of examples that I have shared so far. You can also check out the comprehensive list of examples on Jquery Mobile listview. Till next time, keep sharing - Sharing is Caring.

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...

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 .

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...

A Giant called Google...

    Wondering what you will be reading in this post today and what is "Google Giant"! Well, I was working on a simple project a couple of months back and that is the time when I was amazed and by the size of data that Google Maps servers might be having! As most of the readers (developers and enthusiast included) would know or might have noticed, Google maps are rendered by stitching small images together. You must have observed this on quite a number of occasions, when you see grey tiles when you have a slow internet connection in particular. It takes time for the images or tiles as we call them to be displayed.     Let us try and estimate what could be the size of the Google Maps data! Before proceeding, let's make a few assumptions and considerations. 1. Let's consider the Google Street View maps only. 2. The zoom level that is considered for the calculations is 21 - the max zoom level allowed on Google Maps API. 3. All the numbers are just an esti...

Form info window

         Today we will look at a Google Maps API v3 example to add a form in the information bubble! This is usually required when we wish to accept some data/information from the user! This data can be saved to a server in the form of an XML file or a database! The information can then be retrieved back at a later stage, when necessary!          In this example we will only look at form in the information bubble! The connectivity part with the server will be discussed in another post! So, today's code snippet is as seen below! <html> <head> <title> Google Maps API v3 - Adding marker and info window on Click and creating a form in the infowindow with the lat-lng information in it. </title> <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> <script type="text/javascript"> var map;    //When using ev...
