|
This and the next function allow you to create small sections of an |
|
otherwise static HTML page that you can update on the fly with |
|
Javascript, even in Netscape 4. |
|
|
|
The Javascript fragment returned by this function (no E<lt>scriptE<gt> tag) |
|
must be written to the HTML page once. It will prove the Javascript |
|
function "change(name, content)". Calling the change function with the |
|
name of the section |
|
you want to update, matching the name passed to C<changable_area>, and |
|
the new content you want to put in there, will put the content into |
|
that area. |
|
|
|
B<Note>: Netscape 4 only reserves enough space for the changable area |
|
to contain room for the original contents. You need to "make space" |
|
for whatever changes you wish to make, and be B<sure> to check your |
|
code in Netscape 4. This feature in Netscape 4 is B<not> powerful; |
|
it's adequate for updating a one-line status display, but little more. |
|
This script will set the space to 100% width, so you only need to |
|
worry about height in Netscape 4. |
|
|
|
Modern browsers are much less limiting, and if you can commit to the |
|
user not using Netscape 4, this feature may be used freely with |
|
pretty much any HTML. |

=item get_unprocessed_cgi($query,$possible_names) |
=item &restore_course_settings |
|
|
Modify the %ENV hash to contain unprocessed CGI form parameters held in |
=item &store_course_settings |
$query. The parameters listed in $possible_names (an array reference), |
|
will be set in $ENV{'form.name'} if they do not already exist. |
|
|
|
Typically called with $ENV{'QUERY_STRING'} as the first parameter. |
Restores/Store indicated form parameters from the course environment. |
$possible_names is an ref to an array of form element names. As an example: |
Will not overwrite existing values of the form parameters. |
get_unprocessed_cgi($ENV{'QUERY_STRING'},['uname','udom']); |
|
will result in $ENV{'form.uname'} and $ENV{'form.udom'} being set. |
|
|
|
=item cacheheader() |
Inputs: |
|
a scalar describing the data (e.g. 'chart', 'problem_analysis') |
|
|
returns cache-controlling header code |
a hash ref describing the data to be stored. For example: |
|
|
|
%Save_Parameters = ('Status' => 'scalar', |

'chartoutputmode' => 'scalar', |
|
'chartoutputdata' => 'scalar', |
|
'Section' => 'array', |

'StudentData' => 'array', |

'Maps' => 'array'); |

Returns: both routines return nothing |
