perl code to equal to javascript's history.back()

[jdserran]

hello ^__^
does anyone here know a perl code or function that can be used to go back to a previous page after clicking a link? that is, it does the exact thing when you use javascript's history.back()?
My professor says he "loathes" javascript so I'm afraid that i'll lose marks if I use history.back().

Thank you so much

There is not. Perl has no concept of the history stored in a browsers cache files. Think of things like this:

Perl - server side
javascript - client side

Anything that can be doe on the web server is perls responsibility. Anything that gets done in the browser window is javascripts (or other client side technology) responsibility. Delegate the responsibilites as appropriate.

Wow, Thank you ^__^. I already submitted to my prof the link to my assignment. I just removed the history.back() and simply put in the href the link to the site where I want the user to be directed. all of the inputs on the form will be always erased though...
Thanks again.

You can use the value to hold the user input data if you want to redisplay your form to the user. If you are using the CGI.pm and your form code is in your script or you are using a template system like HTML:::Template you do the following.

my $q = CGI->new;
 
my $first_name = $q->param('fname') || q{};  #Leave the field blank if there is not a value for the textfiled 'fname'.
 
print qq~<input type="text" name="fname" value="$first_name">~;
