| |
=over 4 |
| |
|
| |
=item $dname |
| |
|
| |
The name to prepend to the form elements. |
| |
The form elements defined will be dname_year, dname_month, dname_day, |
| |
dname_hour, dname_min, and dname_sec. |
| |
|
| |
=item $currentvalue |
| |
|
| |
The current setting for this time parameter. A unix format time |
| |
(time in seconds since the beginning of Jan 1st, 1970, GMT. |
| |
An undefined value is taken to indicate the value is the current time |

| |
Also, to be explicit, a value of 'now' also indicates the current time. |
| |
|
| |
=item $special |
| |
|
| |
Additional html/javascript to be associated with each element in |
| |
the date_setter. See lonparmset for example usage. |
| |
|
| |
=item $includeempty |
| |
|
| |
If it is set (true) and no date/time value is provided, |
| |
the date/time fields are left empty. |
| |
|
| |
=item $state |
| |
|
| |
Specifies the initial state of the form elements. Either 'disabled' or empty. |
| |
Defaults to empty, which indiciates the form elements are not disabled. |

# Nested table routines. |
| |
# |
| |
# Routines to display form items in a multi-row table with 2 columns. |
| |
# Uses nested tables to divide form elements into segments. |
| |
# For examples of use see loncom/interface/lonnotify.pm |
| |
# |
| |
# Can be used in following order: ... |
| |
# &start_pick_box() |
| |
# row1 |
| |
# row2 |
| |
# row3 ... etc. |
| |
# &submit_row() |
| |
# &end_pick_box() |
| |
# |
| |
# where row1, row 2 etc. are chosen from &role_select_row,&course_select_row, |
| |
# &status_select_row and &email_default_row |
| |
# |
| |
# Can also be used in following order: |
| |
# |
| |
# &start_pick_box() |
| |
# &row_title() |
| |
# &row_closure() |
| |
# &row_title() |
| |
# &row_closure() ... etc. |
| |
# &submit_row() |
| |
# &end_pick_box() |
| |
# |
| |
# In general a &submit_row() call should proceed the call to &end_pick_box(), |
| |
# as this routine adds a button for form submission. |
| |
# &submit_row() does not require a &row_closure after it. |
| |
# |
| |
# &start_pick_box() creates a bounding table with 1-pixel wide black border. |
| |
# rows should be placed between calls to &start_pick_box() and &end_pick_box. |
| |
# |
| |
# &row_title() adds a title in the left column for each segment. |
| |
# &row_closure() closes a row with a 1-pixel wide black line. |
| |
# |
| |
# &role_select_row() provides a select box from which to choose 1 or more roles |
| |
# &course_select_row provides ways of picking groups of courses |
| |
# radio buttons: all, by category or by picking from a course picker pop-up |
| |
# note: by category option is only displayed if a domain has implemented |
| |
# selection by year, semester, department, number etc. |
| |
# |
| |
# &status_select_row() provides a select box from which to choose 1 or more |
| |
# access types (current access, prior access, and future access) |
| |
# |
| |
# &email_default_row() provides text boxes for default e-mail suffixes for |
| |
# different authentication types in a domain. |
| |
# |
| |
# &row_title() and &row_closure() are called internally by the &*_select_row |
| |
# routines, but can also be called directly to start and end rows which have |

| |
# - htmltag('a', 'this is an anchor', {href => 'www.example.com', |
| |
# title => 'this is a title'}) |
| |
# |
| |

# |
| |
# my $h3 = sub { return htmltag( "h3", @_ ) }; |

# ... and use them: $h3->("This is a headline") |

# |
| |
# - To set up a couple of tags, see sub inittags |
| |
# |
| |
# NOTES: |
| |
# - Empty elements, such as <br/> are correctly terminated, |
| |
# i.e. htmltag('br') returns <br/> |
| |
# - Empty attributes (title="") are filtered out. |
| |
# - The function will not check for deprecated attributes. |
| |
# |
| |
# OUTPUT: content enclosed in xhtml conform tags |
