The following code (using prototype) prevents bots stealing the emailaddresses used on your website. Instead of including the emailaddress directly, use a div with a classname where the email-address needs to be placed:

Hi Bot! My email address is  <div class = "email_here"></div>!! Catch me if you can!

Then, use javascript to replace the email address after the page is loaded:

$$('.email_here').each( function(e) {
  e.update('willem'+'@'+'ajaxorized.com').observe('click', function() { window.location = 'mailto:willem'+'@'+'ajaxorized.com'; }).setStyle({cursor:'pointer'});
	});

Mind the concatenation that is used to prevent stealing from your javascript file. Include this piece of code in your body onload event and no bots will ever steal your email addresses again!

After the image transisition manager we released last week, this week an image reflection script, using unobtrusive javascript. By adding a small piece of javascript to your code you can create this stunning effect. It offers a solution that is:

• Not involved with Flash, or
• with CSS, and
• cross browser (Tested in Firefox, Opera and IE)
• Preloading the images before reflection

Here is a demo on black and on white.

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

I made some improvements on the password strength meters available on the web. Using prototype/scriptaculous, I stole some code from ZeBadger (thanks!) and created a new meter which dynamically changes while typing your password.

If you want to use this script, feel free to download the source and use it on your website.

Enjoy.

In a few years, we (as in web developers) will no longer be speaking the language of (X)HTML4(.01). We will no longer speak the language of <div>'s. No, in a few years, we will no longer be partying like it's 1999. HTML5 (or Web Applications 1.0 as people call it who use the Web 2.0 phrase as well) is on it's way. Since three major Browser vendors (Mozilla, Apple and Opera ) came together as the WhatWG (Web Hypertext Application Technology Working Group) to construct the new HTML standard, the basic thought of the extended HTML version becomes more and more clear. Backwards compatibility width HTML 4.01 and XHMTL 1.1, more specific elements to fulfill the needs of web applications (instead of using <div> for every single one of them), <audio> and <video> tag support, the <dialog> element to describe conversations and many more functionalities. Sounds promising, isn't it?
