      $(".pagination").append("<li id='idactive"+dc+"' class='active mainactive'><a href=#>"+dc+"</a></li>");
    }
    else{
      $(".pagination").append("<li id='idactive"+dc+"' class='mainactive'><a href=#>"+dc+"</a></li>");

$(document).on("click",'.pagination li',function(){
  $(".mainactive").removeClass('active');
  $(this).addClass('active');

  pagenumber=$(this).text();
  console.log("The button number is-->"+$(this).text());
});

 $(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'); }); });
