Questions, comments, or bugs.. just email me...
----------
*Liscence
----------
I have opened this software up under the GNU Public Liscence. Basically, you can do anything you want to it, change it, even sell it, as long as you offer it for free also. I have incliuded the Liscence text file for all who really care.
---------
*Purpose
---------
To produce a minimal javascript solution for a Small Organization's Events Calendar. User's knowledge of this script needs only be restricted to HTML and javascript useage, not programming.
This is Intended as an alternative to CGI programming (perl php java) by those who either do not access to a a cgi-enabled server or by those who do not have the knowledge to program for one.
This non-DTML Javascript Calender is comparatively equivalent to a cgi-version but is a much simpler solution which requires no special configuration from the server end of things.
-------------
*Description
-------------
This package consists of two files both ".js". One library of Calendar calls and one Database of events. More than one Databse of events may be included.
There is one big array 'EVENTS' which holds all events under the index.
You can make as many calendars as you want on the page.
The Calendar has 4 view.
1) compact monthly view with links to a day's events.
2) a full monthly view listing all events for all days.
3) a view of all events for a single week.
4) a view of all events for a single day.
-------
*USAGE
-------
QUICK - make and display the december 2000... and add an event for singing christmas carols on christmas day
-------------------------------->
-HTML CODE:
-------------------------------->
<HTML>
<HEAD>
<SCRIPT LANGUAGE="JAVASCRIPT" SRC="calendar.js"></SCRIPT>
<SCRIPT LANGUAGE="JAVASCRIPT" SRC="events.js"></SCRIPT>
</HEAD>
<BODY>
<SCRIPT LANGUAGE="javascript">
var Dec2000 = new CalendarMonth(2000,12); // no parameters means you want the current month
Dec2000.displayMonth();
</SCRIPT>
</BODY>
</HTML>
-------------------------------->
-------------------------------->
-EVENTS.JS CODE:
-------------------------------->
var evnt1 = new CalendarEvent(2000,12,25);
evnt1.name = "Christmas Day";
evnt1.time = "All Day";
evnt1.location = "Everywhere";
evnt1.description = "Christmas Carols and Presents";
evnt1.addEvent();
-------------------------------->
-------------------
*Events Explained
-------------------
You must make an event. Then manipulate it's attributes directly. Any .js file may contain event entries. Each event must end with a <name>.addEvent(); call to put it into a list for the calendar to use.
The originial idea was to put all events in a single file...
You may do something like this if you wish... but you will have to go in a manually change the include calls whenever you want... where each .js file lives in the same diretory as the page calling it...

-------------------
*Library Explained
-------------------
from top of file to bottom:: better off to read through the documented calendar file itself
-- You have the option of hard coding a colorscheme into the calender. Defined in the top of the file and implemented in CSS. This should be self-explanitory when you look at the top of the file.
-- General Date Knowledge: the names of the months, days of the week, etc... so that you may easily adapt to a different language...
-- An Event: you make an event by (1) declaring it (2) setting its values (3) adding it to a list of events...
(1)
var event1 = new CalenderEvent(2000,1,01); //--> 4 digit year, 1-2 digit month, 1-2 digit day
(2)
event1.name = 'name of event string';
event1.time = 'time the event is going to happen';
event1.location = 'location event is happening';
event1.description = 'description of event';
(3)
event1.addEvent();
The file 'events.js' or any file you choose must contain code in the above form for as many events as you wish. They must all be entered by hand. Any event files must be loaded -after- calendar.js has been loaded.
-- The CalendarMonth itself: months are numbered from 1->12
three ways to make a calendar.
(1) the most useful way... gets current month and year from viewer's computer (as does all javascript)
var newCal = new CaledarMonth();
newCal.displayMonth();
(2) you may specify a year:
var newCal = new CaledarMonth(2001);
newCal.displayMonth();
(3) you may specify both year and month: december 2001
var newCal = new CaledarMonth(2001,12);
newCal.displayMonth();
-- You may manipulate the months as so...
var newCal = new CaledarMonth();
newCal.lastYear(); // moves the calender one year back
newCal.changeYear(-1); // moves the calender one year back
newCal.changeYear(-2); // moves the calender two years back
newCal.nextYear(); // moves the calender one year ahead
newCal.changeYear(1); // moves the calender one year ahead
newCal.changeYear(2); // moves the calender two years ahead
newCal.lastMonth(); // moves the calender one month back
newCal.changeMonth(-1); // moves the calender one month back
newCal.changeMonth(-2); // moves the calender two months back
newCal.nextMonth(); // moves the calender one month ahead
newCal.changeMonth(1); // moves the calender one month ahead
newCal.changeMonth(2); // moves the calender two months ahead
newCal.yesterday(); // moves the calender one day back
newCal.changeDay(-1); // moves the calender one day back
newCal.changeDay(-2); // moves the calender two days back
newCal.tomorrow(); // moves the calender one day ahead
newCal.changeDay(1); // moves the calender one months ahead
newCal.changeDay(2); // moves the calender two months ahead
newCal.displayMonth(); // writes calendar to the screen
-- popupDay -- only called by calendar itself, but you may if you wish
opens a new window and diplays a single day's events
popupDay( YYYYMMDD );
-- popupWeek -- only called by calendar itself, but you may if you wish
opens a new window and diplays a single week's events
popupDay( year, month, day of week the month starts on sun->sat, first legal day of week 1->31, last legal day of week 1->31 );
-- popupMonth -- only called by calendar itself, but you may if you wish
opens a new window and diplays all of a month's events
popupDay( year, month, day of the week the month starts on sun->sat );
-DONE!!
