Smooth Horizontal List Scroll

Posted on 2007-03-19

I've been trying to figure out how to do a smooth scrolling horizontal list with javascript for a while now and I just noticed that the EE menu bar does exactly what I am trying to do (when you click the "More" link). Looking through the source code I couldn't really figure out how they were achieving it. Does anybody know how I can do this effect?

Basically I need to be able to scroll through a horizontal list on the push of a button so that new items come into view. Exactly how they do it here on EE.

Running the risk of getting the standards people on my back:
FF and IE both support the marquee tag
Since it is just html, all things in the marquee are accessible to the browser and to search engines

Here is an alas IE only (unless I can find out how to code onBounce for FF)

<a href="#" onClick="document.getElementById('m1').direction='left'; document.getElementById('m1').start(); return false"><<</a>|
<marquee id="m1" scrollamount="10" onClick="this.stop()" onBounce="this.stop()" behavior="alternate" direction="right" width="75%">
[<a href="">Link01</a>]
[<a href="">Link02</a>]
[<a href="">Link03</a>]
[<a href="">Link04</a>]
[<a href="">Link05</a>]
[<a href="">Link06</a>]
[<a href="">Link07</a>]
[<a href="">Link08</a>]
[<a href="">Link09</a>]
[<a href="">Link10</a>]
[<a href="">Link11</a>]
[<a href="">Link12</a>]
[<a href="">Link13</a>]
[<a href="">Link14</a>]
[<a href="">Link15</a>]
[<a href="">Link16</a>]
[<a href="">Link17</a>]
[<a href="">Link18</a>]
[<a href="">Link19</a>]
[<a href="">Link20</a>]
</marquee>|
<a href="#" onClick="document.getElementById('m1').direction='right'; document.getElementById('m1').start(); return false">>></a>

Would it be possible to get something that doesn't bounce around but just sits there like normal and only scrolls when you click the button? I am looking for the exact functionality of the categories menu at the top of the EE page.

That is not smooth scrolling it is showing and hiding

function ToggleList(zonePosition)
{
  this.first = document.getElementById('compZnNavF');
  this.second  = document.getElementById('compZnNavL');
  this.cont = document.getElementById('compZnNavCont');
  if(zonePosition == 1)
  {
     this.second.className = 'hide';
     this.first.className = '';
     this.cont.className = 'next';
  }
  else
  {
     this.first.className = 'hide';
     this.second.className = '';
     this.cont.className = '';
  }

  this.toggleNavs = function() {
    if(this.first.className == 'hide')
    {
       this.second.className = 'hide';
       this.first.className = '';
       this.cont.className = 'next';
    }
    else
    {
       this.first.className = 'hide';
       this.second.className = '';
       this.cont.className = '';
    }
  }
}
