Page Breaks

[Bill Stephenson]

Does anyone know where I can learn how to make smooth page breaks in
dynamically created HTML documents.

Most of the document is contained in a table and the number of rows is
a variable as well as the number of lines of text in each row.

I'd like to be able to know when a document has exceeded a single page
and then direct where the page break will be and format additional
pages.

Kindest Regards,

This shouldn't be that difficult if you know how many lines/rows you
want on each page. How are you generating the HTML? Are you doing it
via CGI.pm, Template::Toolkit, HTML::Template, something else? That
will be the defining factor as to how you'd go about it.

Without providing actual code, the approach I'd recommend is to
accumulate in a data structure something such as the following.

my $tables = [
[ # table/page 0
[ # row 0
q| line 0 of row 0 |, # this just represents a line of
user-input, presumably as obtained from Text::Wrap
q| line 1 of row 0 |,
q| line 2 of row 0 |,
],
[ # row 1
q| line 0 of row 1 |,
q| line 1 of row 1 |,
q| line 2 of row 1 |,
],
],
[ # table/page 1...
], #....
];

I'm assuming above that you have only one column of text per row.
Anyway, finally in your HTML::Template, loop through $tables and break
your text in the appropriate spots accordingly. If you need more
specific help, ask away.

you can use CSS to manage where you want the page breaks to go

something like :

hr.break {page-break-after: always; width: 0px;}

then call it in your page with something like :
<hr class="break"></hr><br>

hope this helps

There are a number of CPAN modules for doing paging. You cannot know what
the size of the "page" is, though, in general. All you can do is to set the
number of rows per page and then page based on that.
