css代码：

*{ margin:0; padding:0; list-style:none;}
a{ text-decoration:none;}
a:hover{ text-decoration:none;}
.tcdPageCode{padding: 15px 20px;text-align: left;color: #ccc;text-align:center;}
.tcdPageCode a{display: inline-block;color: #428bca;display: inline-block;height: 25px; line-height: 25px; padding: 0 10px;border: 1px solid #ddd; margin: 0 2px;border-radius: 4px;vertical-align: middle;}
.tcdPageCode a:hover{text-decoration: none;border: 1px solid #428bca;}
.tcdPageCode span.current{display: inline-block;height: 25px;line-height: 25px;padding: 0 10px;margin: 0 2px;color: #fff;background-color: #428bca; border: 1px solid #428bca;border-radius: 4px;vertical-align: middle;}
.tcdPageCode span.disabled{ display: inline-block;height: 25px;line-height: 25px;padding: 0 10px;margin: 0 2px; color: #bfbfbf;background: #f2f2f2;border: 1px solid #bfbfbf;border-radius: 4px;vertical-align: middle;}

html代码：

<div class="tcdPageCode"></div>

js代码：

<script src="js/jquery-1.8.3.min.js"></script>
<script src="js/jquery.page.js"></script>
<script>
$(".tcdPageCode").createPage({
pageCount:100,
current:1,
backFn:function(p){
//console.log(p);

p是点击当前的页面的页面，在此处可以进行ajax数据请求
}
});
</script>

jquery.page.js代码：

/**
