Ajaxorized proudly presents... the Image Transition Manager. The Image Transition Manager is a javascript library based on scriptaculous and prototype. It supports several image transitions, such as fading, appearing, sliding, growing and shrinking and more to come.

While working on a project for a customer, I needed to create a kind of slideshow-like effect for presenting several photos of products. When I started out making this 'effect', I found out that I could use this for much more other projects than just this single one. That is what triggered me to create a nice class out of it, so I could easily implement it into my other projects. After showing my first version to Willem, he did some of his magic and extended my class with some other nifty image transitions and functionalities. That is how our Image Transition Manager was born.

Thanks for the introduction Willem and hi all! Willem asked me to write some posts on additional topics like Flash, Actionscript and so on. I hope you will enjoy some of my findings, codes, tips or stories.

For my first contribution i'd like to start sharing a script i wrote a few months ago.

A problem i often encouter is that people, often customers, would like to upload multiple files all together, instead of, what you often see, one file at the time. Of course a very simple solution is to put multiple HTML upload fields on a page, but obviously we could think of a better solution. There are many alternatives on the internet, but most of them aren't customizable and as a real webdeveloper, i would like to create my own solution of course. That is why i created a solution combining three popular webtechnologies; Javascript, Flash and PHP; Javascript constrols the visual aspects, while Flash in combination with PHP handles the upload process.

Since Flash 8, the possibility to communicate between Flash and Javascript is improved, so you can communicate easily using the Flash's ExternalInterface API. With this you can call javascript functions from Actionscript and pass any number of arguments of any data type and vice versa!

To see a working example of my multiple upload solution, click here (no files will be actually uploaded).

I also helped willem out with the design and think we came up with a nice look for this weblog. As you can see at the top we included a menu and added the page 'projects'. I hope we will be able to give this page some content and if i improved my multiple upload script, i will add this as a project. Untill then, you can download the source of this first version here.

When adding this tiny javascript to the onkeyup event of your inputbox, the border will turn green when the email address. It uses scriptaculous' morph function to perform this transformation. See a demo

From now, the number of ajaxorized team members is upgraded to 2, since Martijn joins the team. Martijn and I met in our universities masters program and share the same passion for informatics, web development, javascript, PHP and, of course, black coffee. So, a warm welcome to Martijn!

That right guys, prototype 1.6.0 is on it's way and there is one aspect I want to share with you. In stead of using the old-fashioned 'http-header' way to transport JSON, the prototype framework now eats files with the content-type 'application/json'. A short example:

1. First, we will use prototype to make an ajax request.

    new Ajax.Request('ajax.php',{ onSuccess: handleSuccess }, method: 'get' });

2. After this, on the serverside we set the json headers and output the formatted data using the Services_JSON class:

   <?php
   require_once "services_json.class.php";
    
   /* Set the JSON header */
   header("content-type:application/json");
    
   /* Format some data */
   $aData = array("Car", "Plane", "Train");
    
   $oJson = new Services_JSON(SERVICES_JSON_LOOSE_TYPE);
    
   /* Output */
   echo $oJson->encode($aData);
   ?>

3. And finally this alerts 'Car', 'Plain' and 'Train':

   function handleSuccess(transport) {
     $A(transport.responseJSON).each(function(str) {
       alert(str);
     });
   }
