"I am trying to make dependent drop down in perl script not able to make it"

Show us how you tried this, and how it failed. Your post lacks sufficient information for anyone to give a meaningful answer. How do I post a question effectively?, Tutorials -> PerlMonks for the Absolute Beginner.

My perl file :

    $q->div( { -class => "text" }, "Folder Name : ",

    #my $defaultVal ='0';
    $q->popup_menu( -name=>'foldernameval', -id=> 'folder_name_id',
                      -onchange => 'getReportName()',
                      -type=>'dropdown',
                      -values=> \%folderhash,
                      #-default=>$defaultVal,
                      -default=>['0'],
                    ),
    $q->hidden( -name => ('folder_name', -id=> 'h_folder_name_id', -va
+lue => '' )),
    #q->a( { -href => "javascript:void(0)", -onClick => 'setFolderName
+Id()',  -title => "Populate Report Name" }, "Populate Report Name" ),
    #$q->a( { -href => "signoff.cgi?rm=view_report&fId=3", -onClick =>
+ 'setFolderNameId()',  -title => "Populate Report Name" }, "Populate 
+Report Name" ),
    ),$q->end_div,

    $q->br,
    $q->br,

    $q->div( { -class => "text" }, "Report Name : ",


    $q->popup_menu( -name=>'reportnameval', -id=> 'report_name_id',
                      #-onchange => 'getReportName()',
                      -type=>'dropdown',
                      -values=> \%reportHash,
                      -default=>['0'],
                    ),
    $q->hidden( -name => ('report_name', -id=> 'h_report_name_id', -va
+lue => '' )),
    #$q->a( { -href => "signoff.cgi?rm=view_report&fId=\'$fId\'", -onC
+lick => 'setFolderNameId()',  -title => "Populate Report Name" }, "Po
+pulate Report Name" ),
    $q->a( { -href => "signoff.cgi?rm=view_report&flag=1&fId='$fId'", 
+-onClick => 'setFolderNameId()',  -title => "Populate Report Name" },

    #$q->a( { -href => "signoff.cgi?rm=view_report&fId=$fId",  -title

    ),$q->end_div,

    $q->br,

my Java script method :

function getReportName(){
        var folder_name_id = document.getElementById('folder_name_id')
+.value;
        alert('FOLDER NAME :'+folder_name_id);
        #document.getElementById('h_folder_name_id').value=folder_name
+_id;

       perlExecute(folderId);

}

function perlExecute(url){
    alert('PERLEXECUTE METHOD GET CALLED AND FOLDER NAME ID :'+url);

   function perlExecute(url){

    $.ajax({
    url: '/signOffPageOnDev/js/reportList.pm',
    type: 'get',
    data: {
      'id' : '1234'
   }

  });

     };
  };

Issue , from above Ajax method , my perl file is not getting invoked. this is biggest issue

Your webserver probably isn't configured to execute .pm files. For a long time now CGI has advised against HTML generation. The docs go into detail about the alternatives and suggest templating to separate perl code from HTML, JavaScript etc. Tutorials has links for debugging advise, my own advice, don't use CGI like this.

You forgot code tags.
