AnchorPosition.js
Author: Matt Kruse
Last modified: 10/11/02

DESCRIPTION: These functions find the position of an <A> tag in a document,
so other elements can be positioned relative to it.

COMPATABILITY: Netscape 4.x,6.x,Mozilla, IE 5.x,6.x on Windows. Some small
positioning errors - usually with Window positioning - occur on the 
Macintosh platform.

FUNCTIONS:
getAnchorPosition(anchorname)
  Returns an Object() having .x and .y properties of the pixel coordinates
  of the upper-left corner of the anchor. Position is relative to the PAGE.

getAnchorWindowPosition(anchorname)
  Returns an Object() having .x and .y properties of the pixel coordinates
  of the upper-left corner of the anchor, relative to the WHOLE SCREEN.

NOTES:

1) For popping up separate browser windows, use getAnchorWindowPosition. 
   Otherwise, use getAnchorPosition

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.

// HISTORY
// ------------------------------------------------------------------
// May 17, 2003: Fixed bug in parseDate() for dates <1970
// March 11, 2003: Added parseDate() function
// March 11, 2003: Added "NNN" formatting option. Doesn't match up
//                 perfectly with SimpleDateFormat formats, but 
//                 backwards-compatability was required.

// ------------------------------------------------------------------
// These functions use the same 'format' strings as the 
// java.text.SimpleDateFormat class, with minor exceptions.
// The format string consists of the following abbreviations:
// 
// Field        | Full Form          | Short Form
// -------------+--------------------+-----------------------
// Year         | yyyy (4 digits)    | yy (2 digits), y (2 or 4 digits)
// Month        | MMM (name or abbr.)| MM (2 digits), M (1 or 2 digits)
//              | NNN (abbr.)        |
// Day of Month | dd (2 digits)      | d (1 or 2 digits)
// Day of Week  | EE (name)          | E (abbr)
// Hour (1-12)  | hh (2 digits)      | h (1 or 2 digits)
// Hour (0-23)  | HH (2 digits)      | H (1 or 2 digits)
// Hour (0-11)  | KK (2 digits)      | K (1 or 2 digits)
// Hour (1-24)  | kk (2 digits)      | k (1 or 2 digits)
// Minute       | mm (2 digits)      | m (1 or 2 digits)
// Second       | ss (2 digits)      | s (1 or 2 digits)
// AM/PM        | a                  |
//
// NOTE THE DIFFERENCE BETWEEN MM and mm! Month=MM, not mm!
// Examples:
//  "MMM d, y" matches: January 01, 2000
//                      Dec 1, 1900
//                      Nov 20, 00
//  "M/d/yy"   matches: 01/20/00
//                      9/2/00
//  "MMM dd, yyyy hh:mm:ssa" matches: "January 01, 2000 12:30:45AM"

// HISTORY
// ------------------------------------------------------------------
// 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",...);

//     <SPAN CLASS="cpTodayTextDisabled">Today<SPAN>
// But if you set the prefix like this:
cal.setCssPrefix("Test");

//     <SPAN CLASS="TestcpTodayTextDisabled">Today<SPAN>

cal.offsetX = 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.
