  var pageCount =parseInt(jQuery("#countPage").text()) ;
  var nowPage=parseInt(jQuery("#nowPage").text());
  jQuery(function(){
    $("#pager").pager({ pagenumber: nowPage, pagecount: pageCount, buttonClickCallback: PageClick });//pagenumber:当前页，pagecount:总页数
  });
  PageClick = function(pageclickednumber) {
    $("#pager").pager({
      pagenumber: pageclickednumber, pagecount: pageCount, buttonClickCallback: PageClick
    });
    window.location.href = "/article/search/"+title+"/"+pageclickednumber;
  }
</script>

2.Pager.css

#pager ul.pages{
  display:block;

/*
 * jQuery pager plugin
 * Version 1.0 (12/22/2008)
 * @requires jQuery v1.2.6 or later
 *

 *
 * This version is far from perfect and doesn't manage it's own state, therefore contributions are more than welcome!
 *
 * Usage: .pager({ pagenumber: 1, pagecount: 15, buttonClickCallback: PagerClickTest });
 *
 * Where pagenumber is the visible page number
 *    pagecount is the total number of pages to display
 *    buttonClickCallback is the method to fire when a pager button is clicked.
 *
 * buttonClickCallback signiture is PagerClickTest = function(pageclickednumber)
 * Where pageclickednumber is the number of the page clicked in the control.
 *
 * The included Pager.CSS file is a dependancy but can obviously tweaked to your wishes
 * Tested in IE6 IE7 Firefox & Safari. Any browser strangeness, please report.
