JS CODE

$(".vote").click(function()
{
var id = $(this).attr("id");
var name = $(this).attr("name");
var dataString = 'id='+ id ;
var parent = $(this);
if(name=='up'){
$(this).fadeIn(2).html(' ');
$.ajax({
type: "POST",
url: "up_vote.php",
data: dataString,
cache: false,
context: this,
success: function(html){
parent.html(html);  // show the total number of votes   
$(this).children('.message').fadeIn(100, function() {
$(this).children('.message').html("<h2>you voted</h2>");
})
$(this).children('.message').fadeOut(5000, function() {
$(this).children('.message').html('');
