Re^2: perl javascript help passing varable

[winracer]

thanks I have found out that the $number varable is a array in my perl script and on the page I am useing it on it has a while loop in it. the javascript part is in the head and I have it working that it picks up the 1st $number varable so I am thing that i need to pass the $number array to the javascript array. How do you pass arrays

If it was an array it'd be called @number. However $number may be an array reference. If it is an array reference you can dereference it inside of a double quoted string, as in the example below.

$number = [1,2,3]; 
@number = (4,5,6); 
print "$number @$number @number";

prints something like this:

ARRAY(0x814cc20) 1 2 3 4 5 6

Perl's default behavior is to separate an arrays elements with spaces in double quoted context. If you instead wanted to separate with commas you could do something like this:

my $comma_sep_number = join(",",@$number);
print "My Array Contains: $comma_sep_number";

prints:

My Array Contains: 1,2,3
