* Bazillyo's Spiffy DHTML Popup Calendar v. 1.0 © 2000 S. Ousta
|
|
* - freeware with this comment
|
|
* - for download size, you can strip all spaces & comments except the © notices
|
|
* - Thanks to Chris for the domlay() function
|
|
* - this requires calendarcode.js, calendar.css, and calendarTest.htm
|
|
* - works in IE4.x, IE5.x, NS4.75 possibly 4.x, NS6 (with slight cosmetic issues)
|
|
* - Netscape does display some controls overtop of the layer so layout is important
|
|
*
