// For each menu you create, you must create a matching "FSMenu" JavaScript object to represent
// it and manage its behaviour. You don't have to edit this script at all if you don't want to;
// these comments are just here for completeness. Also, feel free to paste this script into the
// external .JS file to make including it in your pages easier!

// Here's a menu object to control the above list of menu data:
var listMenu = new FSMenu('listMenu', true, 'visibility', 'visible', 'hidden');

// The parameters of the FSMenu object are:
//  1) Its own name in quotes.
//  2) Whether this is a nested list menu or not (in this case, true means yes).
//  3) The CSS property name to change when menus are shown and hidden.
//  4) The visible value of that CSS property.
//  5) The hidden value of that CSS property.
//
// Next, here's some optional settings for delays and highlighting:
//  * showDelay is the time (in milliseconds) to display a new child menu.
//  * switchDelay is the time to switch from one child menu to another child menu.
//    Set this higher and point at 2 neighbouring items to see what it does.
//  * hideDelay is the time it takes for a menu to hide after mouseout.
//  * cssLitClass is the CSS classname applied to parent items of active menus.
//  * showOnClick will, suprisingly, set the menus to show on click. Pick one of 3 values:
//    0 = all mouseover, 1 = first level click, sublevels mouseover, 2 = all click.

//listMenu.showDelay = 0;
//listMenu.switchDelay = 125;
//listMenu.hideDelay = 500;
listMenu.cssLitClass = 'highlighted';
//listMenu.showOnClick = 1;


// Now the fun part... animation! This script supports animation plugins you can add to each
// menu object you create. Here's two to get you started. To enable animation, add one or
// more functions to the menuObject.animations array, and set menuObject.animSpeed to the
// desired percentage of animation to be completed per frame.
// Animation functions are called with a reference to the menu element being animated,
// and a counter variable that changes from 0 to 100 depending on the animation progress.

function animClipDown(ref, counter)
{
 var cP = Math.pow(Math.sin(Math.PI*counter/200),0.75);
 ref.style.clip = (counter==100 ?
  ((window.opera || navigator.userAgent.indexOf('KHTML') > -1) ? '':
   'rect(auto, auto, auto, auto)') :
    'rect(0, ' + ref.offsetWidth + 'px, '+(ref.offsetHeight*cP)+'px, 0)');
};

function animFade(ref, counter)
{
 var f = ref.filters, done = (counter==100);
 if (f)
 {
  if (!done && ref.style.filter.indexOf("alpha") == -1)
   ref.style.filter += ' alpha(opacity=' + counter + ')';
  else if (f.length && f.alpha) with (f.alpha)
  {
   if (done) enabled = false;
   else { opacity = counter; enabled=true }
  }
 }
 else ref.style.opacity = ref.style.MozOpacity = counter/100.1;
};

// I'm applying them both to this menu and setting the speed to 20%. Delete this to disable.
listMenu.animations[listMenu.animations.length] = animFade;
listMenu.animations[listMenu.animations.length] = animClipDown;
listMenu.animSpeed = 20;


// Finally, on page load you have to activate the menu by calling its 'activateMenu()' method.
// I've provided an "addEvent" method that lets you easily run page events across browsers.
// You pass the activateMenu() function two parameters:
//  (1) The ID of the outermost <ul> list tag containing your menu data.
//  (2) A node containing your submenu popout arrow indicator.
// If none of that made sense, just cut and paste this next bit for each menu you create.

var arrow = null;
if (document.createElement && document.documentElement)
{
 arrow = document.createElement('span');
 arrow.appendChild(document.createTextNode('>'));
 // Feel free to replace the above two lines with these for a small arrow image...
 //arrow = document.createElement('img');
 //arrow.src = 'arrow.gif';
 //arrow.style.borderWidth = '0';

 arrow.className = 'subind';
}

addEvent(window, 'load', new Function('listMenu.activateMenu("listMenuRoot", arrow)'));


// You may wish to leave your menu as a visible list initially, then apply its style
// dynamically on activation for better accessibility. Screenreaders and older browsers will
// then see all your menu data, but there will be a 'flicker' of the raw list before the
// page has completely loaded. If you want to do this, remove the CLASS="..." attribute from
// the above outermost UL tag, and uncomment this line:
//addEvent(window, 'load', new Function('getRef("listMenuRoot").className="menulist"'));


// To create more menus, duplicate this section and make sure you rename your
// menu object to something different; also, activate another <ul> list with a
// different ID, of course :). You can hae as many menus as you want on a page.
