Jonathan Snook is at it again creating a new Prototype 1.5.0 Cheat Sheet. He’s gone through and detailed the methods and properties of each of the modules within the Prototype JavaScript library.

With the final release of 1.5.0 coming this is a great time for this new cheat sheet.

• First, I’ve included possible parameters. I’ve used a shorthand to try and fit everything in, so I hope it’s clear. Pretty much anytime a function is passed in, it’s for a callback. Anywhere a parameter needed a little more explanation, i included a word before it to describe it.
• Secondly, I’ve dropped some base classes and internal properties or methods. Some of the stuff only serves a purpose within Prototype and it was just clutter to include it in here.
• I’ve done this up in Illustrator instead of Fireworks to ensure that the PDF version would be clean and clear. I realized a desktop version was somewhat annoying; at least, for me it was.

Dynamic Drive has a great tutorial to help you learn how to create a tabbed section on your website that uses Ajax to update the content.

The tutorial and script will show you how to:

• Fetch and display an external page (from the same domain) inside a container when a tab is clicked on.
• Add a “default” content inside the container to either be shown while no tabs are selected, or to be associated with a specific tab. The default content is added directly to your page and not fetched via Ajax, for sake of server efficiency.
• For each tab, you can not only fetch an external page to be shown, but also load external .css and .js files associated with that page if desired.
• Supports multiple Ajax Tabs Contents on the same page.
• Fully unobtrusive, search engine friendly script. The tabs are simply list based links. For search engines or browsers with JavaScript disabled, the contents will just load as actual pages (instead of inline via Ajax).

I just learned of Gliffy over on Ajaxian. I went to take a look to see what it was all about and I was delightfully surprised.

Gliffy is called a diagram editor in your web browser. Creating an account is free and you can allow others access to edit the diagrams with just their e-mail address, or you can create an image to add to your website or presentation.

This is a great tool for designers and design firms. Creating flow-charts or diagrams of the development process can now be an easy task. The charts that you design are of a great quality too. Gliffy provides drag-and-drop functionality of different pieces as well as easy-as-pie gradient fills (solid fill is an option as well). The connector tool that connects different pieces is easy as well.

Overall, everything I’ve used so far has been pretty easy to understand and put to use. Gliffy is definitely a web app I would recommend.
