I have been a developer for nearly 20 years and a web developer for about 10 years. Over the years, I have considered creating a blog to share the things I have learned (and am learning) about web design and development, but I never seemed to have the time. When I began learning about web development using Ajax and Ajax Frameworks, I decided to take the time to create this blog.
My intention for this blog is to focus primarily on Ajax Frameworks, but since web development requires knowledge of many technologies, I will occasionally write about things such as CSS, Javascript, PHP, MySQL, Flash, etc.
Lately, I have been using JQuery as my primary Ajax tool. Although I have used other Ajax Frameworks in the past (Dojo Toolkit, Yahoo! User Interface Library, Scriptaculous/Prototype), JQuery has thus far been the easiest to learn. In my first few posts I will discuss some of the JQuery Plugins that I have created. Some of these include: a plugin for Google Maps (jquery.imGoogleMaps), Form validation and submission (jquery.imValidateForm), Page Populater (jquery.imPagePopulate), and a plugin to create lists (jquery.imList).
While I am still learning about some of the other Ajax Frameworks, I hope that what I have learned will be helpful to others. Just remember, “When you can pull the pebbles from my hand…”
Although, I have been creating Flash Classes for some time, I had never created a class for my main Flash document – it has always been just a bunch of ActionScript functions. This wasn’t the OO way, so I decided to use the Document Class for the current application that I am working on. I was easy to set up.
I’m creating a new portfolio site using Joomla and Flash. I’ve spent this past weekend creating AS3 class packages (and converting some of my AS2 classes to AS3).
I began loading thumbnails using AS3′s URLRequest and URLLoader in my main application file. I decided to create a package that would request/load the thumbnails, but I needed to return the data from the URLRequest to my main application. I was able to accomplish it using the dispatchEvent method.
Note: This functionality is the basis for my gpUrlLoader class (part of my gpAS3Library).
I’m working on a Flash/AS3 application where I am loading various types of files (images, xml, etc). After writing the same code over and over again, I decided to create an AS3 class to use with my application. This class will load image, swf, text, xml, html, stylesheet, json, and sound files.
Quick Tip:
When using E4X (AS3) to test whether an attribute exists, if you write:
var nX:Number = (shape@nY) ? shape@nY : 0; |
an exception will be thrown. You should instead write:
var nX:Number = (shape.attribute('nY').toString()) ? shape@nY : 0; |
I had hoped that Flash/Flex/AS3 had an hasAttribute method, but I guess this will do.
I just received a Flash/AS3 error message:
1172: Definition could not be found
After many years of developing websites using Flash/AS2, I abandoned Flash web development for the new world of Ajax development (actually, Flash was the first Ajax/Web 2.0 framework).
I recently began to convert some of my AS2 class packages to AS3. I upgraded to Flash CS3 a couple of years ago, but because I have recently been doing a lot of Ajax development (primarily JQuery, YUI, and Dojo), I have only done minor Flash development, limited to Flash banners and other animation projects.
After a lot of frustration, I figured out why I was receiving errors when converting my flash AS2 classes to AS3 packages.
