//              Simple Calendar Widget by Anthony Garrett
//            </A>
//
// Features:  Easily customised
//                  (output date format, colours, language, year range and
//                   week start day)
//            Accepts a date as input
//                  (see comments below for formats).
//            Cross-browser code tested against;
//                  Internet Explorer 6.0.28     Mozilla  1.7.1
//                  Opera             7.52+      Firefox  0.9.1+
//                  Konqueror         3.4.0      Flock    0.4.9
//
// How to add the Calendar to your page:
//            This script needs to be defined for your page so, immediately
//            after the BODY tag add the following line;
//
//                  <script type='Text/JavaScript' src='scw.js'></script>
//
// How to use the Calendar once it is defined for your page:
//            Simply choose an event to trigger the calendar (like an onClick
//            or an onMouseOver) and an element to work on (for the calendar
//            to take its initial date from and write its output date to) then
//            write it like this;

//                  <<event>>="scwShow(<<element>>,this);"
//
//            e.g. onClick="scwShow(document.getElementById('myElement'),this);"
//            or   onMouseOver="scwShow(this,this);"
//
//            You can also disable days of the week by adding arguments to the
//            call to scwShow.  The values should be Sunday = 0 through to
//            Saturday = 6.  A call to scwShow with Friday and Monday disabled
//            would look something like this;
//
//                  scwShow(<<element>>,this,5,1);
//
//            Finally you can use the following technique to run a function
//            when the calendar closes:
//
//                  scwNextAction=<<function>>.runsAfterSCW(this,<<arguments>>);
//                  scwShow(<<element>>,this <<,optional arguments above>>);
//
//            Where <<function>> is a function defined on the calling page
//            and <<arguments>> is the list of arguments being passed to that
//            function.

// Version   Date        By               Description
// =======   ====        ===============  ===========
//   1.0     2004-08-02  Anthony Garrett  Initial release
//   1.1     2005-10-17  Anthony Garrett  Added requested feature to allow
//                                        a click anywhere on the calling page
//                                        to cancel the calendar.
//                                        Added "How to" paragraphs to
//                                        documentation (above).
//                                        Corrected bug that misread numeric
//                                        seed months as one less than entered.
//   1.2     2005-10-26  Anthony Garrett  Allow start of week to be any day.
//   2.0     2005-11-03  Anthony Garrett  Add an IFRAME behind the calendar to
//                                        deal with IE SELECT boxes.
//                                        Renamed all exposed variables and
//                                        functions but kept showCal as entry
//                                        point for backward compatibility.
//                                        Added classes to all HTML elements
//                                        and moved all style attributes to
//                                        inline stlye sheet in customisation
//                                        section.
//   2.1     2005-11-10  Anthony Garrett  Fixed a bug which causes the calendar
//                                        not to display in Firefox when the
//                                        event trigger element's parent was
//                                        not the data element's parent.
//                                        NOTE: This has forced me to add a
//                                              second interface parameter!
//   2.2     2005-11-17  Anthony Garrett  Added input date validation.
//                                        Added input date highlighting (thanks
//                                        to Brad Allan for that suggestion).
//                                        Added optional strict date processing
//                                        (e.g. making 31-Sep an error instead
//                                        of returning 1-Oct). Improved the
//                                        calendar positioning so that CSS
//                                        positioning using DIVs is handled
//                                        correctly.
//   2.3     2005-11-23  Anthony Garrett  Corrected input validation for US
//                                        and other date formats.  Added
//                                        examples for US date processing.
//   2.4     2005-12-10  Anthony Garrett  Added feature to allow disabling
//                                        of specific days of the week, dates
//                                        and date ranges.  Made it optional
//                                        that clicking on the calendar itself
//                                        causes the pop-up to be hidden.
//                                        Thanks to Felix Joussein for the
//                                        feedback.
//   2.41    2005-12-12  Anthony Garrett  Small fix for "Today" display when
//                                        there are no disabled dates.
//   2.42    2005-12-15  Anthony Garrett  Fixed bug where calendar exceeded end
//                                        of range by one month.
//   2.5     2005-12-23  Anthony Garrett  Implemented optional disabling of
//                                        displayed out of range days which
//                                        can occur at the start of the very
//                                        first month and end of the very last.
//                                        Tidied up cursor on calendar
//                                        (thanks to Lou LaRocca for that
//                                        suggestion and others under
//                                        consideration).
//                                        Replaced all browser sniffing with
//                                        more reliable techniques.
//                                        Tightened up and improved access
//                                        to month display with week start
//                                        days other than Zero (Sunday).
//   2.6     2006-01-04  Anthony Garrett  Fixed bug where "disabled" today's
//                                        date could still be used.
//                                        Modified to work with Konqueror.
//                                        Simplified calendar positioning (and
//                                        made it more robust) - Thanks to
//                                        Brad Rubenstein for that suggestion.
//   2.61    2006-01-11 Anthony Garrett   Fixed two digit year entry where year
//                                        parses to a single digit integer.
//   2.62    2006-01-14 Anthony Garrett   Work around Internet Explorer's bug
//                                        where an IFRAME's default src
//                                        attribute is not secure causing the
//                                        'Mixed content' alert when using SSL.
//                                        Thanks to Mark Chapa for reporting
//                                        this problem.
//   2.7     2006-01-18 Anthony Garrett   Simplified date formatting - With

//                                        enhancements that form the basis of
//                                        this change.
//                                        Added optional day disabling

//                                        requirement.

//                                        enabled days.
//                                        Re-organised functions and variables
//                                        to expose only necessary code.

//   3.1     2006-02-15 Anthony Garrett   Added ability to run a function on
//                                        closing the calendar.  The function can

    // in any order.

    // Note: Because the user may select a date then trigger the
    //       calendar again to select another, it is necessary to
    //       have the input date sequence in the same order as the
    //       output display format.  To allow the flexibility of having
    //       a full input date and a partial (e.g. only Month and Year)
    //       output, the input sequence is set separately.
    //
    //       The same reason determines that the delimiters used should
    //       be in scwArrDelimiters.

    // scwZindex controls how the pop-up calendar interacts with the rest

    // set scwBlnStrict = true.  That will cause an error message to

    // day. Thanks to Brad Allan for his feedback prompting this feature.
