This package also includes a small Perl module to make using the calendar easier from Foswiki plugins. This module includes the functions:
$name
is the name of the CGI parameter for the calendar (it should be unique),
$value
is the current value of the parameter (may be undef)
$format
is the format to use (optional; the default is set in configure
). The HTML returned will display a date field and a drop-down calendar.
\%options
is an optional hash containing base options for the textfield.
use Foswiki::Contrib::JSCalendarContrib (); ... my $fromDate = Foswiki::Contrib::JSCalendarContrib::renderDateForEdit( 'from', '1 April 1999'); my $toDate = Foswiki::Contrib::JSCalendarContrib::renderDateForEdit( 'to', undef, '%Y');
renderDateForEdit
affords. $setup
is
the name of
the calendar setup module; it can either be omitted, in which case the method
described in the Mishoo documentation can be used to create calendars, or it
can be 'foswiki'
, in which case a Javascript helper function called
'showCalendar' is added that simplifies using calendars to set a value in a
text field. For example, say we wanted to display the date with the calendar
icon before the text field, using the format %Y %b %e
# Add styles and javascript for the calendar use Foswiki::Contrib::JSCalendarContrib (); ... sub commonTagsHandler { .... # Enable 'showCalendar' Foswiki::Contrib::JSCalendarContrib::addHEAD( 'foswiki' ); my $cal = CGI::image_button( -name => 'img_datefield', -onclick => "return showCalendar('id_datefield','%Y %b %e')", -src=> Foswiki::Func::getPubUrlPath() . '/' . $Foswiki::cfg{SystemWebName} . '/JSCalendarContrib/img.gif', -alt => 'Calendar', -align => 'middle' ) . CGI::textfield( { name => 'date', id => "id_datefield" }); .... }The first parameter to
showCalendar
is the id of the textfield, and the second parameter is the date format. Default format is '%e %B %Y'.
All available date specifiers:
%a - abbreviated weekday name %A - full weekday name %b - abbreviated month name %B - full month name %C - century number %d - the day of the month ( 00 .. 31 ) %e - the day of the month ( 0 .. 31 ) %H - hour ( 00 .. 23 ) %I - hour ( 01 .. 12 ) %j - day of the year ( 000 .. 366 ) %k - hour ( 0 .. 23 ) %l - hour ( 1 .. 12 ) %m - month ( 01 .. 12 ) %M - minute ( 00 .. 59 ) %n - a newline character %p - "PM" or "AM" %P - "pm" or "am" %S - second ( 00 .. 59 ) %s - number of seconds since Epoch (since Jan 01 1970 00:00:00 UTC) %t - a tab character %U, %W, %V - the week number The week 01 is the week that has the Thursday in the current year, which is equivalent to the week that contains the fourth day of January. Weeks start on Monday. %u - the day of the week ( 1 .. 7, 1 = MON ) %w - the day of the week ( 0 .. 6, 0 = SUN ) %y - year without the century ( 00 .. 99 ) %Y - year including the century ( ex. 1979 ) %% - a literal % character
addHEAD
can be called from commonTagsHandler
for adding the header to all pages, or from beforeEditHandler
just for edit pages etc.
An alternative to commonTagsHandler
is postRenderingHandler
which is more efficient since it is called less often.
