I got inspired by kari patila’s post where he uses CSS class to hide spam text using CSS and I wrote something my own by using JavaScript and content to write email address.

.email:after {
content: “@jpkeisala.com”;
}

<a class=”email” xhref=”http://www.jpkeisala.com/v6/#” mce_href=”http://www.jpkeisala.com/v6/#” onclick=”window.location = ‘mailto:’+this.innerHTML+’@jpkeisala.com’”>jp</a>

a bit ugly but i think it works.

This is really cool especially for me old dhtml dude/today XSLT dude (and seems like AJAX dude tomorrow).

$(“ul#menu>li[ul] a.active”).toggle(function(){}

So, what is going on above? I am writing CSS selectors combined with XPath to target specific elements. Library that makes this all possible is called jQuery

XPath is a part of a part of it’s jQuery expression language together with CSS.
jQuery is really worth of checking out.
