1.html页面中

引入

<link rel="stylesheet" type="text/css" href="/stylesheets/pageGroup.css">
 <script src="/javascripts/web/pageGroup.js" type="text/javascript"></script>

            <div id="pageGro" class="cb">
                {{if maxPage>0}}//总页数
                <div class="pageUp">上一页</div>
                <div class="pageList">
                    <ul>
                    </ul>
                </div>
                <div class="pageDown">下一页</div>{{/if}}
                <div id="countPage" style="display:none">{{maxPage}}</div>//总页数
                <div id="nowPage" style="display:none">{{page}}</div>//当前页
                <div id="title" style="display:none">{{title}}</div>//标题
            </div>

2.pageGroup.css

/* CSS Document */
/*分页*/
#pageGro{ 400px; height:25px; margin:0px auto; padding-top:30px;}
#pageGro div,#pageGro div ul li{ font-size:12px; color:#999; line-height:23px; float:left; margin-left:5px;}
#pageGro div ul li{ 22px; text-align:center; border:1px solid #999; cursor:pointer;}
#pageGro div ul li.on{ color:#fff; background:#3c90d9; border:1px solid #3c90d9;}
#pageGro .pageUp,#pageGro .pageDown{ 63px; border:1px solid #999; cursor:pointer;}
#pageGro .pageUp{ text-indent:23px; background:url(/images/pageUp.png) 5px 7px no-repeat;}
#pageGro .pageDown{ text-indent:5px; background:url(/images/pageDown.png) 46px 6px no-repeat;}

3.pageGroup.js

// JavaScript Document
$(function(){
    //根据总页数判断，如果小于5页，则显示所有页数，如果大于5页，则显示5页。根据当前点击的页数生成
    var maxPage=jQuery("#countPage").text();

    var index=parseInt(nowPage);//当前页
    var title=jQuery("#title").text();
    var pageCount =parseInt(maxPage) ;//模拟后台总页数
    //生成分页按钮
    if(pageCount>5){
        page_icon(1,5,0);
        pageGroup(index,pageCount);
    }else{
        //alert("66");
        page_icon(1,pageCount,0);
        pageGroup(index,pageCount);
    }

    //点击分页按钮触发
    $("#pageGro li").live("click",function(){
        if(pageCount > 5){
            var pageNum = parseInt($(this).html());//获取当前页数
            window.location.href = "/article/search/"+title+"/"+pageNum;
