# 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(0 |
|
# &end_pickbox() |
|
# |
|
# 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 |
|
# needs that are not accommodated by the *_select_row() routines. |

# echo_form_input |
|
# |
|
# Generates html markup to add form elements from the referrer page |
|
# as hidden form elements (values encoded) in the new page. |
|
# |
|
# Intended to support two types of use |
|
# (a) to allow backing up to earlier pages in a multi-page |
|
# form submission process using a breadcrumb trail. |
|
# |
|
# (b) to allow the current page to be reloaded with form elements |
|
# set on previous page to remain unchanged. An example would |
|
# be where the a page containing a dynamically-built table of data is |
|
# is to be redisplayed, with only the sort order of the data changed. |
|
# |
|
# Inputs: |
|
# 1. Reference to array of form elements in the submitted form on |
|
# the referrer page which are to be excluded from the echoed elements. |
|
# |
|
# 2. Reference to array of regular expressions, which if matched in the |
|
# name of the form element n the referrer page will be omitted from echo. |
|
# |
|
# Outputs: A scalar containing the html markup for the echoed form |
|
# elements (all as hidden elements, with values encoded). |

# set_form_elements |
|
# |
|
# Generates javascript to set form elements to values based on |
|
# corresponding values for the same form elements when the page was |
|
# previously submitted. |
|
# |
|
# Last submission values are read from hidden form elements in referring |
|
# page which have the same name, i.e., generated by &echo_form_input(). |
|
# |
|
# Intended to be called by onload event. |
|
# |
|
# Inputs: |
|
# (a) Reference to hash of echoed form elements to be set. |
|
# |
|
# In the hash, keys are the form element names, and the values are the |
|
# element type (selectbox, radio, checkbox or text -for textbox, textarea or |
|
# hidden). |
|
# |
|
# (b) Optional reference to hash of stored elements to be set. |
|
# |
|
# If the page being displayed is a page which permits modification of |
|
# previously stored data, e.g., the first page in a multi-page submission, |
|
# then if stored is supplied, form elements will be set to the last stored |
|
# values. If user supplied values are also available for the same elements |
|
# these will replace the stored values. |
|
# |
|
# Output: |
|
# |
|
# javascript function - set_form_elements() which sets form elements, |
|
# expects an argument: formname - the name of the form according to |
|
# the DOM, e.g., document.compose |
