[dancer-users] ajax plugin, serialize a 1D perl array to JSON

[Anand Meher]

Thank you David and Rik for your answers,
                                                                I have one
more question, I tried executing some perl code from a ajax routine :
something like  :

*sub get_stats {*
*# some perl code goes here *
*  ## open a file using perl file open*
*  ## use dancer logger to output to console*
*  ## execute shell commands using system call of perl*
*}*
*
*
*ajax '/killprocess' => sub {*
*    get_stats;*
*
*
*};*
*
*
   But it seems that the perl code is not getting executed, I do not have
anything shown in my logger (console),
  am I doing something wrong over here ?

Thank You
