// *** START EDITING HERE, READ THIS SECTION CAREFULLY! ***

//

//

// Before you start, make sure you've read the "Conditions Of Use" in this HTML document

// or on my site. Anyway, this menu script is split up into several sections. They are:

//

// (1) ITEMSTYLES - These define the colour and size of menu items. Required to run.

// (2) MENU DATA - These specify the text and links in the menu. Required to run.

// (3) MENU EFFECTS - Want to remove, or change borders, shadows and animation? Edit them here,

//     or you can delete this section entirely to remove extra effects.

// (4) EVENTS - Activate the menu(s), and choose creation mode (Dynamic / Fast) etc. I recommend

//     you read it, but you only really need to change it if you want multiple menus on one page,

//     or are trying to combine this with other JavaScripts. Required to run.

// (5) OPTIONAL CODE - Extra features like adding clicking to 'sm:' items or status messages on

//     mouseover. Animation/effects functions are here too. You can skip or delete this entirely.

// (6) FRAMESET README - If you're using a frameset, read this, it explains what you need to do.







// *** (1) ITEMSTYLES ***

//

// First of all we must create ItemStyles to use in the menu. ItemStyles are a collection of

// dimensions, colours, and font/border stylesheet class names that you can 'apply' to menus

// and items later on for a consistent look. The (somewhat lengthy) syntax is:

//

// styleName = new ItemStyle(length of items, spacing after items, 'popout indicator HTML',

//  popout indicator position, padding of text within item, 'out background colour or image

//  filename', 'hover background colour or filename', 'out text stylesheet class', 'hover text class',

//  'out border stylesheet class', 'hover border class', out opacity percentage or null to make

//  it fully opaque, hover opacity percentage or null, 'CSS mouse cursor for normal items',

//  'CSS cursor for sm: and blank items');

//

// One thing that needs explaining is the popout indicator position -- you pass a positive

// integer to position it from the left of the item, and a negative integer to position it from

// the right edge of the item -- see the example code below if that doesn't make much sense.

// Pass an empty string '' as the over or out background for a transparent background.

// If you pass 'hand' as a cursor, the script automatically translates it to 'pointer' for NS6.

// All stylesheet text/border classes come from the <STYLE> tag in this document, you can change

// the font and border colours and styles used there.

//

// Here are some examples used in this menu demo, read through and see how they're formatted,

// then try tweaking some of the numbers and refreshing the page:





// '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.



var hBar = new ItemStyle(22, 0, '', 0, 5, '#ffffff', '#ccff99', 'highText', 'highText', '', '',

 null, null, 'hand', 'default');



// The 'sub Menu' items: 22px long, 0px spacing, a 'greater than' sign for a popout indicator

// (you may wish to use an image tag?), the popout indicator is positioned 15px from the right

// edge of the item, items have 3px padding, some colours, it uses 'lowText' as the dimmed text

// class but 'highText' when it is moused over, and 'itemBorder' as the border stylesheet class.

// No opacity is used, and they have the same cursors as the above ItemStyle.



var subM = new ItemStyle(22, 0, '&gt;', -15, 3, '#66cc00', '#ccff99', 'lowText', 'highText',

 'itemBorder', 'itemBorder', null, null, 'hand', 'default');



// 'subBlank' is similar, but has an 'off' border the same colour as its background so it

// appears borderless when dim, and 1px spacing between items to show the hover border.



var subBlank = new ItemStyle(22, 1, '&gt;', -15, 3, '#66cc00', '#6699CC', 'lowText', 'highText',

 'itemBorderBlank', 'itemBorder', null, null, 'hand', 'default');



// The purplish 'button' style also has 1px spacing to show up the fancy border, and it has

// different colours/text and less padding. They also have translucency set -- these items

// are 80% opaque when dim and 95% when highlighted. It uses the 'crosshair' cursor for items.









// *** (2) MENU DATA ***

//

// Read this section VERY CAREFULLY, it explains how to arrange and tweak the menus themselves.

// To use this script you must create one or more PopupMenu() objects, that will contain all

// the menu data and settings used. This demo contains one, named 'pMenu', although you can

// have as many totally separate menus as you want on one page.

//    Next we add menus and items to the object, using its startMenu() and addItem()

// commands. Each menu object MUST contain one menu named 'root', which is the first, always

// visible menu. The syntax of the startMenu() command is:

//

// startMenu('menu name', Vertical menu (true/false)?, left, top, width, default ItemStyle

//  for items in this menu, optional parent frame/window or layer in which this menu resides);

//

// In order, the parameters are a name for the menu like 'root' or 'mFile', which you can use to

// refer to this menu from other menus, to pop it out.

//    Next, pass 'true' if you want this to be a vertical stacked menu or 'false' if you want this

// to be a horizontal menu bar. You can orientate each menu differently this way.

//   The Left and Top positions allow you to locate this menu either absolutely from the page or

// relative to menu item that pops it out. If you want to offset this menu from the item that pops

// it out, set the positions as NUMBERS, e.g. 130, 10 would put the upper-left corner of this menu

// 130px across and 10px down from the upper-left corner of the item that popped it out.

//   If you put '130', '10' as positions in QUOTES, you can position the menu from the upper-left

// corner of the whole page. These strings can also include formulae to centre or scroll the menu,

// examples are included later on. Note: the 'root' menu is always positioned from the page corner.

//    The 'width' depends on the orientation of the menu -- for vertical menus it's the width,

// for horizontal menus it is the height. Basically, it's the constant dimension for all the items.

//    The parent window or layer parameter is optional, if not specified the current window is

// used -- this example does not use frames. See the frameset example file if you're using them,

// they are strings that when evaluated return a reference, like 'window.top'.

//

// Once you have created a menu, you add items to that menu using the addItem() command.

// You must give it THREE compulsory parameters: 1) The HTML/text to display in the item. 2) The

// menuname/filename/URL the item activates. 3) The action type or target frame of that item.

// All other parameters are optional -- you can override the menu's default ItemStyle with the

// item's own, and optionally override that was well by specifying a list of parameters in the

// same order as an ItemStyle, to give each item its own dimensions / colours etc.

// See the example menu below for an example of these extras...

//

// addItem('Text', 'URL or menuname', 'action type', optional ItemStyle, length, spacing,

//  'popout indicator', popout indicator position, etc... in the same order as ItemStyles);

//

// The third parameter, 'action type', tells the script what to do with the second parameter.

// You can tell the script to load a file in the current window or a particular frame, tell it

// to pop out a menu, or tell it to run a JavaScript command. You do these like this:

//

// addItem('Text', 'file.html', ''); //blank means opens up 'file.html' in the current window.

// addItem('Text', 'file.html', 'parent.content');  //opens 'file.html' in a frame named 'content'.

// addItem('Text', 'menuName', 'sm:');  //pops out another submenu called 'menuName'.

// addItem('Text', 'alert("Hello")', 'js:');  //runs a JavaScript command when clicked.

//

// Frame names should be valid JavaScript syntax, e.g. 'top.frameName' or 'parent.popupWin',

// evaluated from the the window containing the main script (this one). Also, this system means

// 'sm:' items aren't normally clickable. If you do want to add click or mouseover actions to

// items, see the "Optional Code" section of the script below.

// 

// See the example below if this seems complicated, it's quite easy once you get the hang of it.

// Thanks to Martin J. Cole for originally suggesting the syntax!

// If you want more information, there's a FAQ (Frequently Asked Questions) section on my

// site: http://www.twinhelix.com, on the 'Popup Menus' page, or try the 'Site Forums" perhaps.







// A PopupMenu() object must be passed its own name so it can reference itself when the menu

// is active. We also use a 'with' block to work with its properties and functions below.

var pMenu = new PopupMenu('pMenu');

with (pMenu)

{



// *** MOVE OR CENTRE THE MENU HERE ***



// To centre it, or scroll with the window etc, just include a global variable or formula as one

// of the positions. This script includes my page object, which has several useful methods, namely

// 'page.winW()', 'page.winH()', 'page.scrollY()' and 'page.scrollX()'. These return the current

// dimensions of the visible window area and the scroll position of the window, which can be

// used to position menus however you want. Try replacing the first startMenu() below with one of

// these commented lines, and scroll/resize the window to see how they work.



//startMenu('root', false, 'page.winW()/2 - pMenu.menu.root[0].menuW/2', 0, 17, hBar); // Centres.

//startMenu('root', false, 10, 'page.scrollY()', 17, hBar); // Floats with window as you scroll.

//startMenu('root', false, 10, 0, 17, hBar, 'frameName'); // To create in subframe.



// The 'root' menu is horizontal, positioned at (x = 10, y = 0) and is 17px high, and items

// by default use the colours and dimensions in the 'hBar' ItemStyle defined above.

// This menu is also positioned over a similarly-coloured table in the HTML document above.

startMenu('root', true, 0, 190, 160, hBar);



// The text is a space then 'File', and this item pops out the 'mFile' submenu when moused over

// as we've set 'sm:' as the action type. If you want to assign a click action (e.g. navigating to

// a file) to one of these 'sm:' items, see the 'Optional Code' section below.

}





// You can create another menu object here if you want multiple menus on a page.

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

// You can name the other menus in it anything you want.



//var anotherMenu = new PopupMenu('anotherMenu');

//with (anotherMenu)

//{

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

// ... make menus here ...

//}



// Then remember to add it to the event section below...















// *** (3) MENU EFFECTS AND ANIMATION ***





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

// shadows to specific menus. These functions are found in the "Optional Code" section

// below, you can edit them or delete them entirely if you don't want to use them, with

// no harm to the rest of the script itself.





// Add a border to an array of menu names. The syntax is:

// addMenuBorder(menuObject, ["menuName1","menuName2","menuName3"],

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

// Opacity is a number from 0 to 100, or null for no filter, like the ItemStyles.



// Apply a dropshadow to to named menus 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 for no filter), 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, ["mExotic","mMerchandise","mPressures","mWorking","mAbout","mPolicies"],

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





// *** (4) EVENTS ***

//

// In JavaScript, there are document 'events' you need to set so any scripts you are using

// are notified of things like page loading/clicking/scrolling. If you've got several menus

// or another JavaScript entirely in your page, you'll need to add all their functions in here.

// For another menu object, call its functions like update() and position() next to pMenu's,

// I've put examples in to show where these need to go.

//    The reason for these is that every time you set them, they override a previous setting.

// So make sure you collate all the functions that need to be called in here! Syntax:



//object.onevent = function()

//{

// function1();

// function2();

// ...

//}



// That's similar to: <BODY ONEVENT="function1(); function2(); ...">





// The most important event is one used to display the menu by calling one of several methods of

// any menu object(s) you have created. This is where you select the menu creation mode. 'Dynamic'

// mode inserts the menus into the document once it has finished loading and supports features

// like modifying the menu after creation. You update a menu in 'Dynamic' mode by just calling the

// .update() method of a menu object like 'pMenu'.

//    'Fast' creation mode writes the menus to the document here and now, which is faster and

// more reliable in many browsers but only when the document's loading -- you do this by passing

// 'true' without quotes to the update function to signal that we're inline.

//    Opera only supports Fast mode and Netscape 4 only supports in Dynamic mode, so we use

// browser-detect code here. If you find some browser has troubles with one mode or another, try

// the other menu creation method -- see the "Cross-Browser" code at the very top of the SCRIPT

// tag for the variables used.

//    Hardcore tweakers -- there's some extra code commented in the popOver() function at the top

// which lets you create the root menu on page load and other menus only as needed, which might

// be useful for very very large menus in a single frame. Look it up if you want.



if (!isNS4)

{

 // Write menus now in non-NS4 browsers, by calling the "Fast" mode .update(true) method.

 pMenu.update(true);

 var popOldOL = window.onload;

 window.onload = function()

 {

  if (popOldOL) popOldOL();

// *** (6) FRAMESET README ***



// You're looking at the single-frame version of this script right now. This menu does support

// frames with a few extensions -- the core script is the same, but you need to remove the "Events"

// section and include a modified version of it in each loaded file. Get the frameset example from

// my site first, I've put the modified section in a file named "SUBFR.JS".

//

// This script should reside in the topmost frameset. Files loaded in this frameset must satisfy

// two conditions to work:

// 

// 1) They must have all the needed CSS info from the <STYLE> tag included in them, and a small

// JavaScript file (SUBFR.JS) to activate and manage the menus in that frame.

// 

// 2) They must be from the same domain as this frameset -- you can't load in search results or

// similar from another server and pop menus out over it, due to browser JS security rules.

// 

// With the SUBFR.JS file, all you have to do is make sure that in the first line pMenu points to

// the correct pMenu -- that is, located within that frame's parent (this script). If you're using

// multiple menu objects across frames or loading framesets within framesets, you will have to edit

// it, otherwise just leave it as is. To use multiple menus, you need to create them both here and

// then edit SUBFR.JS in the same fashion as the Events section here, calling your second menu

// object whenever pMenu itself is called.

// 

// The example setup allows the menus in sub-frames scroll with their windows. All you have to do is

// use the 'page' object in that frame in a formula to get the current scrolling position of that

// frame, and then add or subtract pixels to position the menus from the scroll position, e.g. for a

// menu in a frame named 'xyz', we would set it to appear in that frame and appear near the top and

// 100px from the left:

// 

// startMenu('menuName', false, 'xyz.page.scrollX()+100', 'xyz.page.scrollY()+10', 17, hBar, 'xyz');

// 

// Of course, third-level menus in other frames can be positioned relative to their parents

// normally. (Remember: strings as positions mean 'absolute' and are calculated as formulae,

// numbers as positions mean 'relative', offset from its parent).

// 

// JS window syntax is OK, so parents can be 'xyz.subFrame.something' if you want, and the SUBFR

// file in that frame/window points back to this one (try scrWin=top rather than scrWin=parent).

// You'll probably want to specify target frames for each menu item, in the same fashion as

// you specified them for the menus themselves -- by default URLs will open in the window in

// which the script is located, the topmost frameset. Try addItem('Text', 'file.html', 'botFr');
