// Cascading Popup Menus v5.2 - Single Frame Menu example script.





// If you're upgrading from v5.1, you can paste your existing menu data in, and if you're

// It can be found on my site, in the syntax helpfile, or in the demo script document.





// 'horizontal Bar' style: menu items that use this ItemStyle are 40px wide, have 10px gaps

// between them, no popout indicator (the ">" in some menus) or popout indicator position,

// 0px padding of the text within items, #336699 background colour, a hover colour of #6699CC,

// 'highText' is the stylesheet class used for the menu text both normally and when highlighted,

// no border styles, 'null' means fully opaque items (set them to numbers between 0 and 100 to

// enable semitranslucency), and the 'hand'/'default' cursors are used for linked/submenu items.

// Here's some more example menus items that address common problems. Try these if you want:

//

// Navigate the whole current window to a page named 'file.html':

//  addItem('Open File', 'file.html', '');

// Open a page in a frame named "content":

//  addItem('Home', '/home/index.html', 'top.content');

// Run a JavaScript command to pop open a new window when clicked:

//  addItem('Catalog', 'window.open("/catalog.html")', 'js:');

// Use a custom ItemStyle you've created:

//  addItem('Text', 'file.html', '', button);

// Make an item 200px long, overriding the default item size:

//  addItem('This contains lots and lots of text', 'file.html', '', null, 200);

// How to open a submenu and also load a file when clicked:

//  with (addItem('Text', 'file.html', '')) sm = 'menuNameHere';

// Popout a submenu named 'mHelp', and give it a JavaScript click action:

//  with(addItem('Help', 'mHelp', 'sm:')) onclick='window.location.href="file.html"';

// This 'mHelp' menu is aligned slightly left of its trigger (-10px).

// Instead of using spaces to indent, consider 'text-indent' in the stylesheet class perhaps?

// The last item is an example of adding extra optional parameters to the addItem() command.

// It uses the subM ItemSyle (regardless of what the rest of this menu uses), is 22px long,

// has 0px spacing after it, and a lesser-than-sign popout indicator positioned 3px from the left

// edge of this item. Note that the parameters after the ItemStyle name are in the same order as

// HIDE OR SHOW DELAYS (in milliseconds) can be customised. Defaults are:

//showDelay = 0;

//hideDelay = 500;

// Specify hideDelay as zero if you want to disable autohiding, and showDelay as a couple of

// hundred if you don't want the menus showing instantaneously when moused over.



// HIDE MENUS ON DOCUMENT CLICK: Try uncommenting this, and perhaps set hideDelay to zero:

//hideDocClick = true;



// You can assign 'oncreate' events to specific menus. By default, the script has only one for

// the root menu that shows it when it is created. You may wish to change it to something like the

// following, which uses the animation function to show the menu, or delay its show altogether.

//menu.root[0].oncreate = function() { pMenu.doVis('root', true) }



// End of 'with (pMenu)' block. That's one menu object created!



}











// CREATE ANOTHER MENU OBJECT here if you want multiple menus on a page, or you can just

// duplicate this entire file and rename 'pMenu' to something else.

// Every menu object MUST have a menu named 'root' in it, as that's always visible.

//with (anotherMenu)

//{

// startMenu('root', .....);

//}









// ******************** MENU EFFECTS ********************

//

// Now you've created a basic menu object, you can add optional effects like borders and

// shadows to specific menus. You can remove this section entirely if you want, the

// functions called are found at the bottom of this file.







// BORDER: Added to all menus in a named object using a specified ItemStyle. The syntax is:

//  addMenuBorder(menuObject, ItemStyle,

//   opacity of border, 'border colour', border width, 'padding colour', padding width);

// Opacity is a number from 0 to 100, or null for solid colour (just like the ItemStyles).



addMenuBorder(pMenu, window.subBlank,

 null, '#666666', 1, '#CCCCDD', 2);







// DROPSHADOW: added to specific ItemStyles again. The syntax is similar, but later on you

// pass arrays [...] for each layer of the shadow you want. I've used two grey layers

// here, but you can use as many or as few as you want. The syntax for the layers is:

//  [opacity, 'layer colour', X offset, Y offset, Width Difference, Height difference]

// Opacity is from 0 to 100 (or null to make it solid), and the X/Y offsets are the

// distance in pixels from the menu's top left corner to that shadow layer's corner.

// The width/height differences are added or subtracted to the current menu size, for

// instance the first layer of this shadow is 4px narrower and shorter than the menu

// it is shadowing.



addDropShadow(pMenu, window.subM,

 [40,"#333333",6,6,-4,-4], [40,"#666666",4,4,0,0]);

addDropShadow(pMenu, window.subBlank,

 [40,"#333333",6,6,-4,-4], [40,"#666666",4,4,0,0]);







// ANIMATION SETTING: We add this to the 'pMenu' menu object for supported browsers.

// IE4/Mac and Opera 5/6 don't support clipping, and Mozilla versions prior to 1.x (such as

// Netscape 6) are too slow to support it, so I'm doing some browser sniffing.

// If you don't want animation, delete this entirely, and the menus will act normally.

// Change the speed if you want... it's the last number, between -100 and 100, and is

// defined as the percentage the animation moves each frame (defaults are 10 and 15).



if ((navigator.userAgent.indexOf('rv:0.')==-1) &&

    !(isOp&&!document.documentElement) && !(isIE4&&!window.external))

{

 pMenu.showMenu = new Function('mN','menuAnim(this, mN, 10)');

 pMenu.hideMenu = new Function('mN','menuAnim(this, mN, -15)');



 // Add animation to other menu objects like this...

 //anotherMenu.showMenu = new Function('mN','menuAnim(this, mN, 10)');

 //anotherMenu.hideMenu = new Function('mN','menuAnim(this, mN, -15)');

}















// ******************** FUNCTIONS CALLED BY THE EFFECTS SECTION ********************



// These can be deleted if you're not using them. Alternatively, if you're using several menu

// data files, you may want to move them to the "core" script file instead.







// This is the "positioning from page anchors" code used by the advanced positioning expressions.

page.elmPos=function(e,p)
{
 var x=0,y=0,w=p?p:this.win;
 e=e?(e.substr?(isNS4?w.document.anchors[e]:getRef(e,w)):e):p;
 if(isNS4){if(e&&(e!=p)){x=e.x;y=e.y};if(p){x+=p.pageX;y+=p.pageY}}
 if (e && this.MS && navigator.platform.indexOf('Mac')>-1 && e.tagName=='A')

 {
  e.onfocus = new Function('with(event){self.tmpX=clientX-offsetX;' +
   'self.tmpY=clientY-offsetY}');
  e.focus();x=tmpX;y=tmpY;e.blur()
 }
 else while(e){x+=e.offsetLeft;y+=e.offsetTop;e=e.offsetParent}
 return{x:x,y:y};
};









// Animation:

//

// Each menu object you create by default shows and hides its menus instantaneously.

// However you can override this behaviour with custom show/hide animation routines,

// as we have done in the "Menu Effects" section. Feel free to edit this, or delete

// this entire function if you're not using it. Basically, make functions to handle

// menuObj.showAnim() and .hideAnim(), both of which are passed menu names.

//

// Customisers: My lyr.clip() command gets passed the parameters (x1, y1, x2, y2)

// so you might want to adjust the direction etc. Oh, and I'm adding 2 to the dimensions

// to be safe due to different box models in some browsers.

// Another idea: add some if/thens to test for specific menu names...?



function menuAnim(menuObj, menuName, dir)

{

 // The array index of the named menu (e.g. 'mFile') in the menu object (e.g. 'pMenu').

 var mD = menuObj.menu[menuName][0];

 // Add timer and counter variables to the menu data structure, we'll need them.

 if (!mD.timer) mD.timer = 0;

 if (!mD.counter) mD.counter = 0;



 with (mD)

 {

  // Stop any existing animation.

  clearTimeout(timer);



  // If the litNow() array doesn't show this menu as lit, and we're still showing it,

  // force a quick hide (this stops miscellaneous timer errors).

  //if (dir>0 && !menuObj.litNow[menuObj.menu[menuName][0].parentMenu]) dir = -100;



  // If the layer doesn't exist (cross-frame navigation) quit.

  if (!lyr || !lyr.ref) return;

  // shows and doesn't hide on very quick mouseovers.

  // Alpha fade in IE5.5+. Mozilla's opacity (pre-v1.7) isn't well suited as it's an inheritable

  // property rather than a block-level filter, and it's slow, but uncomment and try it perhaps.

  // WARNING: This looks funny if you're mixing opaque and translucent items e.g. solid menus

  // with dropshadows. If you're going to use it, either disable dropshadows or set the opacity

  // values for your items to numbers instead of null.

  //if (isIE && window.createPopup) lyr.alpha(counter&&(counter<100) ? counter : null);



  // Clip the visible area. The syntax is:   lyr.clip(left, top, right, bottom);

  // As you can see in these examples, three are static at either zero or the edge of a menu item,

  // and either the top or bottom is a complicated formula based on the 'counter' variable which

  // counts from 0 to 100 and back again; this give a nice accelerating-sliding animation.

  // Feel free to experiment with your own animations, here are some samples (use one only):



  // Straightforward downwards clipping animation (default setting):

  lyr.clip(0, 0, menuW+2, (menuH+2)*Math.pow(Math.sin(Math.PI*counter/200),0.75) );

  // If you want, comment out the above line and enable this one to animate bottom-upwards:

  //lyr.clip(0, (menuH+2)-(menuH+2)*Math.pow(Math.sin(Math.PI*counter/200),0.75), menuW+2, menuH+2);

  // Another alternative: Move+clip sliding animation. Looks really cool :).

  //if (!counter) mD.origY = lyr.y();

  //var newY = (menuH+2)-(menuH+2)*Math.pow(Math.sin(Math.PI*counter/200),0.75);

  //lyr.clip(0, newY, menuW+2, menuH+2);

  //lyr.y(mD.origY - newY);



  // Increment the counter and if it hasn't reached the end (counter is 0% or 100%),

  // set the timer to call the animation function again in 40ms to contine the animation.

  // Note that we hide the menu div on animation end in that direction.

  counter += dir;

  if (counter>100) { counter = 100; lyr.sty.zIndex = mD.zIndex }

  else if (counter<0) { counter = 0; lyr.vis('hidden') }

  else timer = setTimeout('menuAnim('+menuObj.myName+',"'+menuName+'",'+dir+')', 40);

 }

// not using them. Basically, they assign a string to pMenu.menu.menuName[0].extraHTML, which
