"Now, if there are 100 headers, i would have to assign variables 100 times separately. so its better to make it dynamic. "

I recommend a hybrid solution that dynamically creates static Javascript:

use strict; use warnings; use Mojolicious::Lite; get '/' => sub { my $c = shift; my @array = qw( foo bar baz qux ); $c->stash( vars => \@array ); $c->render( template => 'js', format => 'html' ); }; app->start; __DATA__ @@ js.html.ep <script> <% for ( 0 .. $#$vars) { %> var headname<%= $_ + 1 %> = "<%= $vars->[$_] %>"; <% } %> </script>

Yields:

<script> var headname1 = "foo"; var headname2 = "bar"; var headname3 = "baz"; var headname4 = "qux"; </script>

UPDATE: Better yet would be to shove them all into a Javascript array:

use strict; use warnings; use Mojolicious::Lite; get '/' => sub { my $c = shift; my @array = map "'$_'", qw( foo bar baz qux ); $c->stash( vars => \@array ); { local $" = ', '; $c->render( template => 'js', format => 'html' ); } }; app->start; __DATA__ @@ js.html.ep <script> var headname = <%== "[@$vars]" %>; alert( headname ); </script>

to format your post; it's "PerlMonks-approved HTML":



  • 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.
