Sending JavaScript variables to a perl program
hi...
is there a good way to send JavaScript variables to a perl program
WITHOUT using a form? (or mybe with a form, but i don't want the program
to return anything, and i don't want a popup window to show up...)
I know it sounds wierd, so i'll give an example...
lets say i have a statistics gathering script called stats.pl and it
returnes nothing to STDOUT when run, only writes to a data file.
I can tell the user's IP by using $ENV{'REMOTE_ADDR'} etc., but i want
to know some more stuff, like the user's screen size or the local time,
which i can tell using JavaScript. My problem is sending this data to my
perl script. The problem when using a form is that the browser loads a
new document for the result, even if it is empty.
If you got my intention, please help...
thanks.

First off it would be nice if JavaScript had a
way to open a socket connection back to the
web-server to send a message to it that
contained all of the 'query string' information
that you would want to pass back to the web-server
for 'logging purposes'. But that is not easy and a
bit more complicated to try and pull off.
One way to solve your problem is to have a 'prefatory'
page that collects the data, and then POST's that
back to the web-server before showing the 'real page'.
This way the 'flow' seems 'reasonable' to the user.
You could have one cgi script say
DataCollector.cgi
that contains some java scripting, to get all of
the relevant data, but calls
RegularProcess.cgi
which will first off call your stats.pl script
with the relevant information, and then return
the appropriate web_page to the user.

The HTML::Entities module can do this for you:
#!/usr/bin/perl
use strict;
use warnings;
use HTML::Entities;
print encode_entities('abc');
Along with other related functions -- perldoc HTML::Entities

Re: formatting money $12.00
#!/usr/bin/perl -w
$num =1.12345;
my $tax_formated = sprintf(%.2f, $num); # --- THIS LINE
### $tax_formated is used in a few places
The important thing is, does it do what youo are expecting it to do?
Well yes, I think so. I wanted to cut down on the times I was calling sprintf(%.2f,
$num);
This is new function to me :)
One more quick question here has to with filling a HASH
my (%bags_ordered,$bag);
# is it ok to mix match the type of variables inside a
# my vars declaration?
@bags = param('handbag'); #CGI.pm
foreach my $bag (@bags){
$bags_ordered{$bag} = {} unless exists $bags_ordered{$bag};
}
### Is the code below -- more better and or correct?
foreach my $bag (@bags){
$bags_ordered{$bag} = $bag unless exists $bags_ordered{$bag}
}
Thanks!

Trouble with CGI::Carp
I am trying to prevent generic crashes going to the browser in my
CGI program. I am using :
use CGI::Carp 'fatalsToBrowser';
and eventually I will use a set_message. However I have a
strange problem in that the following subroutine, if there are
errors on the statement execution, it does not send the error to
the browser. I can put my own 'die' in there and it works.
I am forced to use the 'eval' statement, as you can see on the
first SQL statement.
Would be grateful for any guidance.
Gary
sub add_record {
(code snipped here and there for brevity).
### Subject ###
if($add_subject) {
my $sql = SQL1;
INSERT INTO valid_subjects
values('$login','$subject',NULL)
SQL1
# Execute the SQL statement.
$sth= $dbh-prepare($sql) or die preparing: ,$dbh-errstr;
eval { $sth-execute };
if ($@) { failure($co); }
}
### From address ###
if($add_from_addr) {
my $sql = SQL2;
INSERT INTO valid_senders
values('$login','$fromaddress',NULL)
SQL2
# Execute the SQL statement.
$sth= $dbh-prepare($sql) or die preparing: ,$dbh-errstr;
$sth-execute or die (failure($co));
}

You can get untar programs that run on windows, WinZip understands .tar.gz and most other similar programs do as well. but I don't think that will help you any to run it on a windows version of Perl. You should see if you can get the Convert-BER package for the particular version of Perl for windows that you have. You might have been right five years ago, but not now. Most CPAN modules can be instaled under Windows just like anywhere else. The only problem is that the base install of Windows doesn't contain a C compiler, but 1) you don't need it for Perl-only modules (ftp://ftp.microsoft.com/Softlib/MSLFILES/nmake15.exe is enough) and 2) you may use the compiler that comes with cygwin or some others. Convert::BER is pure Perl so if you are using ActivePerl, download the nmake, unpack the .tar.gz into a temporary dir and run perl Makefile.PL nmake nmake test nmake install and you should be fine.
