Hacking at 0300

Two new additions to flexcal, which is now at version 2.2. See the code and a demo, that uses my new github pages.

Mouse Wheel

The calendar now responds to wheel events, changing the month with scroll up/down and changing the calendar tab with scroll left/right. I initially tried to throttle it since my trackpad was too sensitive, but that made it too slow. I'm not sure waht to do about that. It works well with an actual mouse wheel, thoug.

Keith Wood's Calendars

Keith Wood is maintaining the jQuery plugin that eventually became the official jQuery UI datepicker. His version, however, handles multiple calendar systems, much like flexcal (though I like my plugin, of course). His code is on github, and the documentation is on his personal site. He has support for many calendar systems, and I wanted to let flexcal use that. I don't use his datepicker code, just the calendar systems.

I'm using a naming convention of language-calendar, like he-jewish for a calendar localized to hebrew, using a Jewish lunar calendar. It's the opposite of Woods, who uses calendar-language, like islamic-ar for a calendar localized to arabic, using the Islamic lunar calendar. For my names, the default language is en and the default calendar system in gregorian. Thus, islamic would be an English language Islamic calendar, and zh-TW would be a Taiwanese Chinese Gregorian calendar (my parser is smart enough to not be confused by the extra hyphen). The language codes are ISO 639 two-letter codes.

There is a new function, $.ui.flexcal.tol10n(name) that creates a localization object with appropriate language and calendar system. It is designed to be transparent; doing

$('input').flexcal({
  calendars: ['ar-islamic']
});

will look in the existing $.ui.flexcal.l10n object for 'ar-islamic', then try to find it in the jQuery UI datepicker localizations (if those are loaded) (note that jQuery UI only uses Gregorian calendars), then Woods's calendars if they exist.

You can use the bridge directly if you want; $.ui.flexcal.tol10n(name) returns a localization object that you can modify as desired and then pass to flexcal.

To use this, you need to include the necessary script files: jquery.calendars.js for the basic code, jquery.calendars.name.js (like jquery.calendars.islamic.js) for the calendar-system-specific routines (these are all in English), and jquery.calendars.name-language.js (like jquery.calendars.islamic-ar.js)for the language-specific localization, or jquery.calendars.language.js for language-specific localization using the Gregorian calendar.

Of note, the text that is used for the "Next Month" and "Previous Month" is localized for the datepicker, not the underlying calendar system, so if you want that included automatically, also include the jquery.calendars.picker-name.js. I have a little hack in flexcal so you do not have to include the entire jquery.calendars.picker.js package; just include the jquery.calendars.picker-mock.js before including the localization code.
It should be clear which files to include if you look at the list.

TODO

His calendar code also has some nice formatting options, which flexcal does not have out of the box, though it is possible with some work. I'd like to get a bridge to work with my code as well.
Some other options that would be nice include: setting the first day of the week (now is fixed at Sunday) and having the option of showing or selecting days from other months.
