Hi monks,

I've got the following little test, but i cant seem to get it to print a backspace in the textarea field.
Does anyone know if this is possible?

#!/usr/bin/perl
$| = 1;

use strict;
use warnings;

print "Content-type: text/html\n\n";
print "Starting Test<br>\n";
print "<textarea rows=1 style=\"border:1px #FFFFFF solid; overflow:hid
+den;\">";

my $count = 0;
for (my $i = 1; $i <= 16; $i++) {
        print ".";
        $count++;
        print "\b\b\b\b" if ($count == 4);
        $count = 0 if ($count == 4);
        sleep(1);
} # end-for

print "</textarea><br>";
print "Completed Test!\n";
exit(0);

Also, on a side note, could someone tell me how to combine these two lines into one :) ;

print "\b\b\b\b" if ($count == 4);
$count = 0 if ($count == 4);

I guess i could do:

if ($count == 4) { $count = 0; print "\b\b\b\b"; }

but it seems somewhat inelegant.

Cheers,

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
