How to trim the end of an iteration value?

I've got a json value in a tpl that is being iterated the guts looks something like (code not exact for times sake you get the idea):

var foo=[

iw iterate begins here

{dctvalue,dctvalue},
{dctvalue,dctvalue}, (This trailing }, is the problem)

iw iterate closes here

}];

Not sure how to deal with the this trailing iterate code, I'm thinking use iw_last somehow to trim the ending "},"?

Ideas?

Thanks in advance.

Isn't the last curly brace in front of the square brace the real problem? Can't you just remove that one?

If you need more help, then post your original code... or rewrite the segment as perl in between <iw_perl> tags instead of lobotomizing yourself with iw_pt tags.

I'd opt for the second one - if you're using TPL's - which are Perl based - then doing the code in Perl is really trivial - something like:

my @vals = retrieve_all_values_from_field;
my $val = join(',', @vals);

Alternatively, based on existing code - you could just use a simple regex like:

#... set $val, appending comma to each value ...
$val =~ s|,$||;
