Hello everyone,

I'm brand new to JavaScript/jQuery, and I'm trying to build a navigation menu in HTML/CSS with hide/show script in jQuery.

this is my JavaScript now:

Code:
<script src="http://code.jquery.com/jquery-1.6.1.min.js" type="text/javascript"></script>
<script type="text/javascript">
var timeout    = 500;
var closetimer = 0;
var ddmenuitem = 0;

function jsddm_open()
{  jsddm_canceltimer();
   jsddm_close();
   ddmenuitem = $(this).find('ul').css('visibility', 'visible');}

function jsddm_close()
{  if(ddmenuitem) ddmenuitem.css('visibility', 'hidden');}

function jsddm_timer()
{  closetimer = window.setTimeout(jsddm_close, timeout);}

function jsddm_canceltimer()
{  if(closetimer)
   {  window.clearTimeout(closetimer);
      closetimer = null;}}

$(document).ready(function()
{  $('.pMenu > li').bind('mouseover', jsddm_open)
   $('.pMenu > li').bind('mouseout',  jsddm_timer)});

document.onclick = jsddm_close;
</script>
that sits right inside the <head> tag.

These are the CSS styles:

Code:
