Calendar Release Notes
*** version 2.6.0 ***
+ Fixed incorrect cell index parsing from cell id attribute, when
Calendar id contained "cell".
+ Added text to previous month, next month and close icons, to
enhance accessibility for screen-readers.
+ Fixed issue with bubbled previous month, next month click events
missing target information in certain browsers (due to replaced HTML),
by delaying click event handling through a setTimeout.
+ Added destroy method to Calendar/CalendarGroup
+ Fixed incorrect clear method behavior for CalendarGroup where all
pages would be set to the same month.
+ Refactored code to reduce minified Kweight.
*** version 2.5.2 ***
+ CalendarGroup toDate method no longer throws javascript exception
*** version 2.5.1 ***
+ Fixed bug with mindate, maxdate being applied incorrectly if
set to a day on which time change took place (DST, E.U Summertime)
and the day is not the first day of the week.
+ Fixed DateMath.getWeekNumber implementation to return correct
week numbers. The older implementation would return Week 0 for
certain weeks (e.g. the week starting Sun Dec 28th 2008)
To suppor the fix, DateMath.getWeekNumber has a signature
change in 2.5.1 and can now support U.S Week calculations based
on Jan 1st identifying the first week of the year, as well as
ISO8601 week calculations based on Jan 4th identifying the first
week of the year
The arguments which the method expected prior to 2.5.1 were not
being used in calculating the week number. The new signature is:
DateMath.getWeekNumber(Date dt, Number firstDayOfWeek, Number janDate)
Where:
dt is the date for which week number is required
firstDayOfWeek is the day index identifying the first
day of the week. Default is 0 (Sunday).
janDate is the date in the first week of January, which
identifies the first week of the year.
Default is YAHOO.widget.DateMath.WEEK_ONE_JAN_DATE (1)
NOTE: Calendar instances themselves do not currently expose a
configuration property to change the week numbering system
used. A "janDate" value is not passed to the getWeekNumber
method, when used by Calendar, resulting in it using the default value.
Therefore, ISO8601 week numbering can be generated for Calendars
by setting the value of YAHOO.widget.DateMath.WEEK_ONE_JAN_DATE
to 4.
*** version 2.5.0 ***
+ Prevent default event handling in CalendarNavigator enter key
listener, to prevent automatic form submission when using Calendar
inside a form.
+ Added workaround to DateMath.add and subtract for Safari 2 (webkit)
bug in Date.setDate(n) which doesn't handle value of n less than -128
or greater than 127 correctly.
See: http://brianary.blogspot.com/2006/03/safari-date-bug.html
+ Added border, padding and margin rules to Calendar Sam Skin to
protect Sam Skin's look and feel when Calendar is used with
YUI base.css
*** version 2.4.0 ***
+ Added CalendarNavigator (year selector) feature to allow the user to
jump to a year/month directly without having to scroll through months
sequentially.
The feature is enabled/configured using the "navigator" configuration
property.
+ Added Custom Events:
showNav/beforeShowNav
hideNav/beforeHideNav,
renderNav/beforeRenderNav
To Calendar/CalendarGroup, in support of the CalendarNavigator
functionality.
+ Added Custom Events:
show/beforeShow
hide/beforeHide
To Calendar and CalendarGroup. Returning false from a
beforeShow/beforeHide listener can be used to prevent the Calendar
from being shown/hidden respectively.
+ Added Public Methods:
getCellIndex(date) [ Calendar ]
getCalendarPage(date) [ CalendarGroup ]
toDate(dateArray) [ Calendar/CalendarGroup ]
removeRenderers() [ Calendar/CalendarGroup ]
+ The Calendar/CalendarGroup constructor is now more flexible:
* It no longer requires an "id" argument.
In it's simplest form, a Calendar/CalendarGroup can be
constructed by simply providing a container id or reference.
var cal = new YAHOO.widget.Calendar("container");
-or-
var containerDiv = YAHOO.util.Dom.get("container");
var cal = new YAHOO.widget.Calendar(containerDiv);
An id for the Calendar does not need to be provided, and will be
generated from the container id by appending an "_t" suffix to the
container id if only the container is provided.
* The container argument can be either a string, representing the
id of the container, or an HTMLElement referring to the container
element itself, as suggested in the example above.
* If an HTMLElement is provided for the container argument and the
element does not have an id, one will be generated for it using
YAHOO.util.Dom.generateId().
* The older form of Calendar/CalendarGroup signature, expecting
both an id and containerId is still supported and works as it did
prior to 2.4.0.
+ Fixed performance issue, where the same custom renderer was being
applied multiple times to the same cell.
+ Added getDate(year, month, date) factory method to the DateMath utility,
which can be used to create JavaScript Date instances for years less
than 100.
The default Date(year, month, date) constructor implementations across
browsers, assume that if year < 100, the caller is referring to the
nineteen hundreds, and the year is set to 19xx instead of xx (as with
the deprecated setYear method). However Date.setFullYear(xx) can
be used to set dates below 100. The above factory method provides a
construction mechanism consistent with setFullYear.
+ Changed Calendar/CalendarGroup/DateMath code to use the DateMath.getDate
method, so that 2 digit years are not assumed to be in the 1900's.
NOTE: Calendar's API already expects 4 digit date strings when referring
to years after 999.
*** version 2.3.1 ***
+ Changed Calendar/CalendarGroup to render an empty title bar element
when "close" is set to true, but "title" has not been set, to allow Sam
Skin to render a title bar correctly.
*** version 2.3.0 ***
+ Added checks to select, selectCell, deselect and deselectCell methods
to ensure the Calendar/Calendar group was not set to an invalid state
by programmatically selecting unselectable dates or cells.
+ Added new locale configuration properties for the Month/Year label
used in the Calendar header (MY_LABEL_MONTH_POSITION,
MY_LABEL_YEAR_POSITION, MY_LABEL_YEAR_SUFFIX, MY_LABEL_MONTH_SUFFIX).
Japan is an example locale, where customization of the Month/Year
label is required.
+ Changed "first", "last" class names to "first-of-type", "last-of-type",
to avoid collision with YUI Grids' use of the "first" class name.
+ Added public isDateOOB method, to check if a given date is outside of
the minimum/maximum configuration dates of the Calendar.
+ Deprecated YAHOO.widget.Calendar.browser, refactored to use
YAHOO.env.ua instead.
+ Removed overflow:hidden from default Calendar/CalendarGroup container
for non-IE6 browsers to fix clipping issue with IE7 when CalendarGroup
was inside a box with a specific width. overflow:hidden is still
required for IE6 with an iframe shim.
+ Added Opera container width calculation fix to CalendarGroup.show
method, to fix incorrect wrapping when using a CalendarGroup which is
initially rendered hidden (display:none). Previously this fix was
only applied on render.
*** version 2.2.2 ***
+ Fixed problem with selected dates being shared across instances, when
more than one Calendar/CalendarGroup was on the page
*** version 2.2.1 ***
+ Fixed problem with selectCell adding duplicate selected date entries
for dates which were already selected
+ Fixed problem with CalendarGroup iframe shim not covering the
CalendarGroup title area
+ Removed javascript:void(null) from close button and cell links which
was interrupting form submission and firing onbeforeunload in IE
+ Fixed problem with CalendarGroup getSelectedDates returning invalid
results, when used in conjunction with the "selected" Config property
(either passed in the constructor config argument or set seperately
after construction)
+ Refactored Calendar and CalendarGroup to improve performance,
especially when working with a large number of instances in
IE6
*** version 2.2.0 ***
+ Image customization can now be done through CSS. Images for Close,
Left and Right Arrows are now pulled in using CSS defined in
calendar.css and by default use relative paths to the images in
the same directory as calendar.css.
+ Deprecated Calendar.IMG_ROOT and NAV_ARROW_LEFT, NAV_ARROW_RIGHT
configuration properties. Customizations based on older releases
which set these properties will still function as expected.
+ Deprecated CalendarGroup.CSS_2UPCLOSE. Calendar's Style.CSS_CLOSE
property now represents the new default CSS class (calclose) for
the close button. CSS_2UPCLOSE is still applied along with
CSS_CLOSE to the new markup for the close button to support existing
customizations of the CSS_2UPCLOSE CSS class (close-icon)
+ Fixed problem with Safari setting Calendar pages to incorrect dates
if the pages spanned a year boundary in CalendarGroups with 3 or more
pages, due to a bug in Safari's implementation of Date setMonth
+ Fixed problem with CalendarGroup setMonth rendering Calendar pages
with incorrect dates in all browsers if current pages spanned year
boundary
+ Fixed incorrect CalendarGroup logging statement in calendar-debug.js
+ Fixed domEventMap support for Safari versions prior to 2.0.2,
caused by hasOwnProperty not being supported
+ Removed unused private property : _pageDate from Calendar class
*** version 0.12.2 ***
+ Corrected documentation for clearTime function to reflect the
change from midnight to noon
*** version 0.12.1 ***
+ Calendar and CalendarGroup now automatically parse the argument
passed to setMonth and setYear into an integer, eliminating
potential concatenation bugs.
*** version 0.12 ***
+ New documentation format implemented
+ Calendar2up and Calendar_Core are now deprecated. Now, Calendar alone
represents the single Calendar instance, and CalendarGroup represents
an n-up instance, defaulting to 2up
+ Added semantic style classes to Calendar elements to allow for
custom styling solely using CSS.
+ Remapped all configuration properties to use the Config object
(familiar to those who use the Container collection of controls).
Property names are the same as their previous counterparts, but
wrapped into Calendar.cfg, allowing for runtime reconfiguration of
most properties
+ Added "title" property for setting the Calendar title
+ Added "close" property for enabling and disabling the close icon
+ Added "iframe" property for enabling an iframe shim in Internet
Explorer 6 and below to fix the select bleed-through bug
+ pageDate moved to property: "pagedate"
+ selectedDates moved to property: "selected"
+ minDate moved to property : "mindate", which accepts a JavaScript
Date object like its predecessor, but also supports string dates
+ maxDate moved to property : "maxdate", which accepts a JavaScript
Date object like its predecessor, but also supports string dates
+ Moved style declarations to initStyles function
+ Optimized event handling in doSelectCell/doCellMouseOver/
doCellMouseOut by only attaching the listener to the outer
Calendar container, and only reacting to events on cells with
the "selectable" CSS class.
+ Added domEventMap field for applying DOM event listeners to cells
containing specific class and tag combinations.
+ Moved all cell DOM event attachment to applyListeners function
+ Added getDateByCellId / getDateFieldsByCellId helper functions
+ Corrected DateMath.getWeekNumber to comply with ISO week number
handling

+ Deprecated onDeselect. Created beforeDeselectEvent, which
automatically subscribes to its deprecated predecessor.
+ Deprecated onChangePage. Created changePageEvent, which automatically
subscribes to its deprecated predecessor.
+ Deprecated onRender. Created renderEvent, which automatically
subscribes to its deprecated predecessor.
+ Deprecated onReset. Created resetEvent, which automatically
subscribes to its deprecated predecessor.
+ Deprecated onClear. Created clearEvent, which automatically
subscribes to its deprecated predecessor.
+ Corrected setMonth documentation to refer to 0-11 indexed months.
+ Added show and hide methods to Calendar for setting the Calendar's
display property.
+ Optimized internal render classes to use innerHTML and string buffers
+ Removed wireCustomEvents function
+ Removed wireDefaultEvents function
+ Removed doNextMonth / doPreviousMonth
+ Removed all buildShell (header, body, footer) functions, since
the Calendar shell is now built dynamically on each render
+ Wired all CalendarGroup events and configuration properties to
be properly delegated to Calendar
+ Augmented CalendarGroup with all built-in renderers, label functions,
hide, show, and initStyles, creating API transparency between Calendar
and CalendarGroup.
