$(document).ready(function() {
  var pageItem = $(".pagination li").not(".prev,.next");
  var prev = $(".pagination li.prev");
  var next = $(".pagination li.next");

  pageItem.click(function() {
    pageItem.removeClass("active");
    $(this).not(".prev,.next").addClass("active");
  });

  next.click(function() {
    $('li.active').removeClass('active').next().addClass('active');
  });

  prev.click(function() {
    $('li.active').removeClass('active').prev().addClass('active');
  });
