Cooler modal popup example – how to open multiple popups, scrolling pop ups per page

Some time back I came up with a cooler modal pop up window using CSS3 and JavaScript specifically for mobile webkit browsers. The example that I presented had only a single button, a click on it would open a modal pop up window.

In this post I have a similar example but this time multiple pop ups can be opened from the same page. Opening multiple pop up’s from a single page was requested by some of my readers. And here it is. I will not go deep into explaining the bits and parts of how to create a pop up window. You can go through my previous post for that. But first let’s check a demo (meant only for web-kit based browsers):

How to run this in Firefox, IE and other browsers?
For this you need to make changes in the CSS file. Add CSS3 prefixes for other browsers similarly as it is there for -webkit- . CSS3 junkies would already know what I am talking about.

Handy eBook to have available – by Chris.M
Overall, the book does a great job of getting you up and running with Edge Inspect. The first couple of chapters focus on getting the application installed on your computer, and then getting it set up on your mobile devices. Though the installation is fairly straightforward, the instructions they provide are detailed with plenty of screenshots, so you should have no issues getting set up.
They also give an overview of the best features of Edge Inspect. I’ve been using Edge Inspect for a while now and even I learned a few new things. The application really does make mobile testing incredibly easy with remote inspection and console log.
The eBook wraps up with some great resources for using Edge Inspect. If you are thinking of working on Responsive Web Design, Adobe Edge Inspect is an invaluable tool. I think the eBook is super handy to have as a reference, and for 5 bucks, why not?

worth having it as a reference – by Siddarth Kalyankar
“Instant Adobe Edge Inspect Starter” indeed is a starter for developers who wish to explore the possibilites of using Adobe Edge Inspector tool during their day to day development activity. It talks about Step-by-step, hands-on recipes to debug, test, and preview web applications on multiple mobile devices with Adobe Edge Inspect (Previously known as “Adobe Shadow” ).
This book assumes that the person who reads this is already into mobile web development and address some of his/her problems which are faced during the development cycle. This book is not intended to help you start doing mobile web development, but if you are web developer and willing to do mobile web development, this could come in handy for you as well.
The books briefs you about what is Adobe Edge Inspect, What are the reasons to use it and What you can do with with it. The main focus is on installation of the required components on your computer, the Edge inspect client on mobile device , how to pair mobile device with your computer and how to debug and preview. I found this information quiet useful as the entire installation process has been very well illustrated with screen shots focusing on Mac/ Windows operating systems, and Android/IOS for mobile device. The author has also provided with the code which can be used by first time developers to get started on their mobile web development venture.
If you are looking at speeding up your mobile web development, Adobe Edge Inspect is the tool and this book is worth having it as a reference.

Creating a simple List in Sencha Touch 2.0

Creating a simple data list in Sencha Touch 2.0 has changed over the way we used to create data lists in Sencha 1.0.  Changes have been made in the way a data Model is created and the data fields are defined, but the overall concept remains the same.  Here is a quick tutorial along with a demo,

Fade-in/Fade-out animation using CSS3

Let us try a simple fade-in and fade-out animation in CSS3. Looks very simple, lets see how to achieve it. We will be using only CSS3 for the animations and only a little bit of java script for changing the CSS classes dynamically. First let’s check the demo,

and this is is how the demo looks.

HTML5 – SVG Demographic Map Dashboard Example

The previous month I was busy with experimenting a dashboard which had choropleth/thematic maps, charts, interactivity, also dynamic data reading. Here is what I came up with. This one is a HTML5 based dashboard. Looks like a Flex application isn’t it? The map is of United States and the demographic data are just demo data although they are read from XML files. What’s good is that this application can scale, in the sense that the data can be fed to it by services running on remote servers and the map can display that. Also the data distribution has two categories a) Equal Distribution b) Quantiles method. Had to look up the statistic book again for these two. Play with the application and let me know if you like it.

The application is meant for computer browsers that support HTML5 Canvas and Inline SVG. You can best view it in Chrome, FF and Safari.

Click the image to see the live demo.
(The demo link has slight problems at the moment. I am fixing this right now. But you can view the source code in the browser and download it if needed.)

Note: The script code needs a bit of re-factoring. I am working on it partially due to time constraints. Once you have the code, you can modify it as per your needs.

Issue: I am noticing some issues with the select lists on the top. The Equal Intervals/Quantiles select list some times does not make any changes in the map. I will look into this, but you might want to test it.

Creating dynamic SVG elements in JavaScript

While I was working on a HTML5 project I found this problem of creating SVG (Scalable Vector Graphics) elements
dynamically in JavaScript. For example creating vector circles inside a for loop and adding them to the page. HTML5
supports inline SVG, so you can directly use <svg>your code</svg> inside <body> to create vector graphics. But I had the task of creating them in the script. So I have put forward a small example and here is how to do it.

To create a vector circle of radius 50,

var svgNS = "http://www.w3.org/2000/svg";

var myCircle = document.createElementNS(svgNS,"circle");
myCircle.setAttributeNS(null,"id","mycircle");
myCircle.setAttributeNS(null,"cx",100);
myCircle.setAttributeNS(null,"cy",100);
myCircle.setAttributeNS(null,"r",50);
myCircle.setAttributeNS(null,"fill","black");
myCircle.setAttributeNS(null,"stroke","none");
