// HISTORY
// ------------------------------------------------------------------
// Apr 24 2007: Billy Bacon - Added all new methods for new Flight Finder 
//		implementation which uses a textbox to display the date selected 
//		rather than drop-down menus. Also modified disabled dates functionality.
//		Added boolean to determine if disabled dates should be in between given dates or
//		prior to start date and after end date.
// Jan 28 2006: Edited so that the month chosen in the corresponding 
// 		date field is the first to display. Changed the way the disabled 
//    	dates are handled. Before, the dates compounded, and thus with each
//      calendar change, more dates were blacked out. If one went back in
//    	time, the blackouts did not repeal. They do now. 	
// Feb 7, 2005: Fixed a CSS styles to use px unit
// March 29, 2004: Added check in select() method for the form field
//      being disabled. If it is, just return and don't do anything.
// March 24, 2004: Fixed bug - when month name and abbreviations were
//      changed, date format still used original values.
// January 26, 2004: Added support for drop-down month and year
//      navigation (Thanks to Chris Reid for the idea)
// September 22, 2003: Fixed a minor problem in YEAR calendar with
//      CSS prefix.
// August 19, 2003: Renamed the function to get styles, and made it
//      work correctly without an object reference
// August 18, 2003: Changed showYearNavigation and 
//      showYearNavigationInput to optionally take an argument of
//      true or false
// July 31, 2003: Added text input option for year navigation.
//      Added a per-calendar CSS prefix option to optionally use 
//      different styles for different calendars.
// July 29, 2003: Fixed bug causing the Today link to be clickable 
//      even though today falls in a disabled date range.
//      Changed formatting to use pure CSS, allowing greater control
//      over look-and-feel options.
// June 11, 2003: Fixed bug causing the Today link to be unselectable
//      under certain cases when some days of week are disabled
// March 14, 2003: Added ability to disable individual dates or date
//      ranges, display as light gray and strike-through
// March 14, 2003: Removed dependency on graypixel.gif and instead 
///     use table border coloring
// March 12, 2003: Modified showCalendar() function to allow optional
//      start-date parameter
// March 11, 2003: Modified select() function to allow optional
//      start-date parameter
/* 
DESCRIPTION: This object implements a popup calendar to allow the user to
select a date, month, quarter, or year.

COMPATABILITY: Works with Netscape 4.x, 6.x, IE 5.x on Windows. Some small
positioning errors - usually with Window positioning - occur on the 
Macintosh platform.
The calendar can be modified to work for any location in the world by 
changing which weekday is displayed as the first column, changing the month
names, and changing the column headers for each day.

USAGE:
// Create a new CalendarPopup object of type WINDOW
var cal = new CalendarPopup(); 

// Create a new CalendarPopup object of type DIV using the DIV named 'mydiv'
var cal = new CalendarPopup('mydiv'); 

// Easy method to link the popup calendar with an input box. 
cal.select(inputObject, anchorname, dateFormat);
// Same method, but passing a default date other than the field's current value
cal.select(inputObject, anchorname, dateFormat, '01/02/2000');
// This is an example call to the popup calendar from a link to populate an 
// input box. Note that to use this, date.js must also be included!!
<A HREF="#" onClick="cal.select(document.forms[0].date,'anchorname','MM/dd/yyyy'); return false;">Select</A>

// Set the type of date select to be used. By default it is 'date'.
cal.setDisplayType(type);

// When a date, month, quarter, or year is clicked, a function is called and
// passed the details. You must write this function, and tell the calendar
// popup what the function name is.
// Function to be called for 'date' select receives y, m, d
cal.setReturnFunction(functionname);
// Function to be called for 'month' select receives y, m
cal.setReturnMonthFunction(functionname);
// Function to be called for 'quarter' select receives y, q
cal.setReturnQuarterFunction(functionname);
// Function to be called for 'year' select receives y
cal.setReturnYearFunction(functionname);

// Show the calendar relative to a given anchor
cal.showCalendar(anchorname);

// Hide the calendar. The calendar is set to autoHide automatically
cal.hideCalendar();

// Set the month names to be used. Default are English month names
cal.setMonthNames("January","February","March",...);

// Set the month abbreviations to be used. Default are English month abbreviations
cal.setMonthAbbreviations("Jan","Feb","Mar",...);

// Show navigation for changing by the year, not just one month at a time
cal.showYearNavigation();

// Show month and year dropdowns, for quicker selection of month of dates
cal.showNavigationDropdowns();

// Set the text to be used above each day column. The days start with 
// sunday regardless of the value of WeekStartDay
cal.setDayHeaders("S","M","T",...);

// Set the day for the first column in the calendar grid. By default this
// is Sunday (0) but it may be changed to fit the conventions of other
// countries.
cal.setWeekStartDay(1); // week is Monday - Sunday

// Set the weekdays which should be disabled in the 'date' select popup. You can
// then allow someone to only select week end dates, or Tuedays, for example
cal.setDisabledWeekDays(0,1); // To disable selecting the 1st or 2nd days of the week

// Selectively disable individual days or date ranges. Disabled days will not
// be clickable, and show as strike-through text on current browsers.
// Date format is any format recognized by parseDate() in date.js
// Pass a single date to disable:
cal.addDisabledDates("2003-01-01");
// Pass null as the first parameter to mean "anything up to and including" the
// passed date:
cal.addDisabledDates(null, "01/02/03");
// Pass null as the second parameter to mean "including the passed date and
// anything after it:
cal.addDisabledDates("Jan 01, 2003", null);
// If between is true, pass two dates and disable all dates in between and including the these two dates.
// If between is false, pass two dates and disable all dates prior to start date and after end date.
cal.addDisabledDates("January 01, 2003", "Dec 31, 2003", between);

// When the 'year' select is displayed, set the number of years back from the 
// current year to start listing years. Default is 2.
// This is also used for year drop-down, to decide how many years +/- to display
cal.setYearSelectStartOffset(2);

// Text for the word "Today" appearing on the calendar
cal.setTodayText("Today");

// The calendar uses CSS classes for formatting. If you want your calendar to
// have unique styles, you can set the prefix that will be added to all the
// classes in the output.
// For example, normal output may have this:
//     <SPAN CLASS="cpTodayTextDisabled">Today<SPAN>
// But if you set the prefix like this:
cal.setCssPrefix("Test");
// The output will then look like:
//     <SPAN CLASS="TestcpTodayTextDisabled">Today<SPAN>
// And you can define that style somewhere in your page.

// When using Year navigation, you can make the year be an input box, so
// the user can manually change it and jump to any year
cal.showYearNavigationInput();

// Set the calendar offset to be different than the default. By default it
// will appear just below and to the right of the anchorname. So if you have
// a text box where the date will go and and anchor immediately after the
// text box, the calendar will display immediately under the text box.
cal.offsetX = 20;
cal.offsetY = 20;

NOTES:
1) Requires the functions in AnchorPosition.js and PopupWindow.js

2) Your anchor tag MUST contain both NAME and ID attributes which are the 
   same. For example:
   <A NAME="test" ID="test"> </A>

3) There must be at least a space between <A> </A> for IE5.5 to see the 
   anchor tag correctly. Do not do <A></A> with no space.

4) When a CalendarPopup object is created, a handler for 'onmouseup' is
   attached to any event handler you may have already defined. Do NOT define
   an event handler for 'onmouseup' after you define a CalendarPopup object 
   or the autoHide() will not work correctly.
   
5) The calendar popup display uses style sheets to make it look nice.
