hi i am new at codeigniter. i want to change my div tag using jquery ajax.

As per your comment your current code seems to be like this -

function submitVote(frmName){ 
  $.ajax({ 
   type: "POST",
   url: "<?php echo SITEURL; ?>/community/community/add_vote/?",
   data: "vote="+the_value+"&poll="+poll,
   success: function(msg){ 
    alert(msg);
   }
 }); 
}

First thing i would like to add is from where are you getting the the_value and poll valuesenter code here ? Because you have mentioned nowhere regarding this in your code. secondly there is no need to send ? in your url. Also the parameter frmName which you are taking in function is used nowhere.

Your code can be modified to work properly as follows -

function submitVote(frmName){ 
      $.ajax({ 
       type: "POST",
       dataType: 'text',
       url: "<?php echo SITEURL; ?>/community/community/add_vote/",
       data: "vote="+the_value+"&poll="+poll,
       success: function(msg){ 
        //i am assuming that from controller in msg you are sending the total number of votes to that particular entity after ending current vote.
        $('#div id where you have displayed your current vote count').html(msg);
       }
     }); 
    }
