in reply to how can i get the index value of array during runtime

Hi phemal, try using Array::Each module,

use strict; use warnings; use Array::Each; my @x = qw( p e r l ); my $one = Array::Each->new( \@x ); while( my( $x, $i ) = $one->each() ) { printf "%3d: %s\n", $i, $x; }
TIMTOWDI

Otherwise,

use strict; use warnings; my @x = qw( p e r l ); for my $index (0..$#x){ print "$index : $x[$index]\n"; }

[Corion]: Meh. I think I have now the parts down that I want from a simple Javascript frontend for single-page- applications with a aPerl backend. But it seems that all Javascript templating modules either don't support two-way binding (which would be nice) or ...
[Corion]: ... don't support server-side precompilation (which means the client has to compile all templates to Javascript themselves), or are giant frameworks that expect to do everything (which is not what I want)
[Corion]: I feel that there is a talk somewhere in there, either about the structure and parts, or how I used several parts to get a complete whole.
[Corion]: Maybe I can still find something that is compatible with handlebars.js (which has JS precompilation) but allows for two-way data binding (which is great for the UI)
