Question

I have a hashmap with some information(key and value) in a perl file. I want to display them in HTML output and each displayed (key, value) will link to something. When I click the link then there will be some information there.
Anyone suggests me how can I do that. Is this similar to creating a CGI file and use CGI.pm? I will update more detail on this question later.

Answer 1

Depending on the data you’re trying to display, something like HTML::Table may be useful if you want to display it in tabular format and don’t want the drugery of assembling the appropriate HTML yourself.

For instance, you could do something like:

my $table = HTML::Table->new(-columns => 2);
for my $key (sort keys %hash) {
    $table->addRow($key, $hash{$key});
}
$table->print;

Also, there is a free Beginning Perl book available online, which has a chapter devoted to CGI scripts, along with a lot of other useful information.

If this is more than just a simple one-off script, you might also wish to consider using one of the many Perl web frameworks like Dancer, Catalyst, Mojo etc.
