Hello All,
I am trying to develop a toggle function like http://www.lutsr.nl/yui/toggle/
But it works a little different as them. When user enters the glossary page, he sees a full list of
Alphabet with all the techical terms explaination
All — A | B | C | E | G | H | M | P | Q | R | S | T | U | Z |
ActiveSync®
Microsoft® ActiveSync est l’ application permettant à un pocket pc d’ échanger des informations avec un ordinateur . Le Pocket PC doit utiliser Microsoft Windows Mobile™ ou Windows CE.
Bluetooth®
Le Bluetooth permet aux informations d’ être transmises entre les appareils électroniques qui ont le Bluetooth. Si vous utilisez le Bluetooth, vous n'avez pas besoin de connecter les périphériques à l'aide de câbles.
.............................
If the user clicks B
Alphabet, the rest of content will hide, except B.
and B will be move to top of the section.
If the user clicks All aplphabet, the whole list will be reset.
What I have now, it is able to show/hide and listen to click event. Here is my source code:
<a href="#A" class ="toggle" rel="A_section,fade,20"> A</a> |
<a href="#B" class ="toggle" rel="B_section,fade,20"> B</a> |
Script:
//Load JavaScript Ready event.

}

if(controlNode && refEl) {

YAHOO.util.Dom.removeClass(controlNode,"selected");
YAHOO.util.Dom.removeClass(refEl,"show");
