Are you talking to me? I didn't ask for anything.

Since you already mess around with "Ajax", the drop-down stuff is a cinch. (Or are you using one of those fancy cross-browser libraries, which make mastering browser scripting a matter of minutes?) Whenever your month or year changes your attached change listener(s) retrieve month and year (in case the month changed to February) from the according dropdowns; unless you got February you look up your number of days of the according month (e.g. a simple array with 12 entries); for February you use your well-known formula to calculate your number of days. Remove all superfluous options from your day-drop down box (a maximum of three) or append missing ones. Gregor -- http://www.gregorkofler.com

Or you use one of the thousands of pop-uppy calendar things out there that allow one to choose a date with a couple of mouse clicks. No fiddling with damn nasty thirty line long select elements. |
