Ok guys, this time we won´t do any php. This time it will all be about Flash and Actionscript 3.0. As I told you in some of the tutorials before I am working for a German ISP at the moment which is on it´s way to launch a new portal. This portal website will also hold some widgets that will provide the users with some basic functionality.
This tutorial will cover the alarm clock that comes with two layouts, analog and digital.
Like I wrote recently I am contracted at a German ISP at the moment to build a new Portal where one can put several different widgets on his or her personal web page. Similar to igoogle. My customer also wants to provide the possibility of own widgets to external developers, so to avoid security issues we will need to sandbox each of those widgets, but like we all know that can be a serious problem when it comes to the “evil unleashed monster” javascript. So in order to leash it inside a sandbox on a secure chain we came across google caja.
I came across this problem a week ago when I tried to develop an interface between an Iframe, or in Detail it’s content, and the iframes parent page. Turns out that the following code wouldn´t work in FireFox although all other browsers, yes even our friend the Internet Explorer, would behave as expected.
Lately I started a new project at a German ISP where we (the team and me) have to develop several extensions to jQuery in order to build a framework to work with in this project. I am using jQuery for several years now but never had to develop my own extensions, because most of the plugins available solved problems I came a cross. This time I have to do my own and started questioning uncle google about how to do it. No surprise there are several approaches to do a plugin for jQuery, but none of the tutorials I found answered all my Questions completely, so I decided to write this sum up of what I learned.
