The year, month and day can all be determined from the first * parameter which is a Date object, but because many people will explicitely * need the year, month or day, we pass them too to speed things up (since we * already know them at the time the handler is called). * * Here is an example of a not-so-complex handler: * * \code * function my_DateStatus(date, year, month, day) { * var str = date.print("%Y/%m/%d"); * if (str >= '2000/01/01' && str <= '2000/12/31') { * return true; // disable all dates in 2000 * } * if (str == "1979/08/03") { * return "birthday"; * } * return false; * } * calendar.setDateStatusHandler(my_DateStatus); * \endcode * * The above handler will disable all dates in 2000 (returns true) and * highlight "1979/08/03" using the class "birthday".

Here's * what the return value means: * * - \b true: the date will be disabled. * - \b false: no action taken (date stays enabled). * - "disabled": the date will be disabled. * - "other_string": the "other_string" will be added to the cell's class name. * - "disabled other_string": the date will be disabled and "disabled other_string" * will be added to cell's class name; this helps one make a date disabled while * still highlighting it in a special way. * * Note that user defined class names should have an associated CSS part * somewhere in the document that specifies how the days will look like; * otherwise, no difference will be visible. For instance, for highlighting * "birthday" dates, one should also add: * * \code * .birthday { color: #f00; } * \endcode * * somewhere in the CSS of the calling document. (the above will make them * red). * * Disabled dates are not clickable; however, if one overrides the "disable" * CSS class, or if the cell also gets an "other_string" class that contains * settings that override the "disabled" class, those cells might not look * "disabled" but still behave so. * * \b WARNING: this function gets called 28 to 31 times each time a month is * displayed.
