# %TOPIC% ![](http://www.dementia.org/twiki//view/screenshot.gif) %SHORTDESCRIPTION%
## Summary of Contents This module packages the [Mishoo JSCalendar](http://dynarch.com/mishoo/calendar.epl) Javascript in a form suitable for use with TWiki. ## Detailed Documentation Read [the Mishoo documentation](http://www.dementia.org/twiki//view/doc/html/reference.html) or [visit the demo page](http://www.dementia.org/twiki//view) for detailed information on using the calendar widget. This package also includes a small Perl module to make using the calendar easier from TWiki plugins. This module includes the functions: ### TWiki::Contrib::JSCalendarContrib::renderDateForEdit($name, $value, $format [, \\%cssClass]) -> $html This is the simplest way to use calendars from a plugin. - `$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. Example: use TWiki::Contrib::JSCalendarContrib; ... my $fromDate = TWiki::Contrib::JSCalendarContrib::renderDateForEdit( 'from', '1 April 1999'); my $toDate = TWiki::Contrib::JSCalendarContrib::renderDateForEdit( 'to', undef, '%Y'); ### TWiki::Contrib::JSCalendarContrib::addHEAD($setup) This function will automatically add the headers for the calendar to the page being rendered. It's intended for use when you want more control over the formatting of your calendars than `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 `'twiki'`, 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 TWiki::Contrib::JSCalendarContrib; ... sub commonTagsHandler { .... # Enable 'showCalendar' TWiki::Contrib::JSCalendarContrib::addHEAD( 'twiki' ); my $cal = CGI::image_button( -name => 'img_datefield', -onclick => "return showCalendar('id_datefield','%Y %b %e')", -src=> TWiki::Func::getPubUrlPath() . '/' . TWiki::Func::getTwikiWebname() . '/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. ### Using the Calendar in user forms You can also use the calendar directly in your own hand-built forms, without having to write any code. Just add this inline in the topic text: %INCLUDE{"%TWIKIWEB%/JSCalendarContribInline"}% Then, to display a calendar icon next to a text input field: If the contrib is installed, you will see such a field here: ### Installation Instructions You do not need to install anything in the browser to use this extension. The following instructions are for the administrator who installs the extension on the server where TWiki is running. Like many other TWiki extensions, this module is shipped with a fully automatic installer script written using the BuildContrib. - If you have TWiki 4.2 or later, you can install from the `configure` interface (Go to Plugins->Find More Extensions) - See the [installation supplement](http://twiki.org/cgi-bin/view/Plugins/BuildContribInstallationSupplement) on TWiki.org for more information. - If you have any problems, then you can still install manually from the command-line: 1. Download one of the `.zip` or `.tgz` archives 2. Unpack the archive in the root directory of your TWiki installation. 3. Run the installer script ( `perl _installer` ) 4. Run `configure` and enable the module, if it is a plugin. 5. Repeat for any missing dependencies. - If you are **still** having problems, then instead of running the installer script: 1. Make sure that the file permissions allow the webserver user to access all files. 2. Check in any installed files that have existing `,v` files in your existing install (take care **not** to lock the files when you check in) 3. Manually edit LocalSite.cfg to set any configuration variables.
%X% WARNING: SYSTEMWEB is not defined in this TWiki. Please add these definitions to your [[Main/TWikiPreferences]], if they are not already there:
   * Set SYSTEMWEB = %TWIKIWEB%
* Set USERSWEB = %MAINWEB%
- An administrator can customize the appearance of the calendar by setting the following in `LocalSite.cfg`
Setting Default
$TWiki::cfg{JSCalendarContrib}{style} 'blue'
$TWiki::cfg{JSCalendarContrib}{lang} 'en'
$TWiki::cfg{JSCalendarContrib}{format} '%e %b %Y'
