|
|
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. |
