在做前端项目中，总是需要自己手写类似于这样的分页效果：
这就需要使用jQuery.pager.js文件，其使用方法为：在html中引入三个文件，分别为：
<link rel="stylesheet" type="text/css" href="../Pager.css"/>
<script src="../jquery.min.js"></script>
<script type="text/javascript" src="../jquery.pager.js"></script>
特此附上Pager.css文件：
#pager ul.pages{
display:block;
border:none;
text-transform:uppercase;
font-size:12px;margin:10px 0 50px;padding:;
}
#pager ul.pages li{
/*list-style:none;*/
/*float:left;*/
/*border:1px solid #ccc;*/
/*text-decoration:none;*/
margin:0px 5px 0 0;
border: 1px solid #e3e3e3;
color: #333;
display: inline-block;
height: 22px;
line-height: 22px;
padding: 0 10px;
text-align: center;
_zoom:;*display:inline;
}
#pager ul.pages li.page-number:hover{
/*border:1px solid #003f7e; */
background:#f1f1f1; color:#000; text-decoration:none
}
#pager ul.pages li.pgEmpty{

/*
* jQuery pager plugin
* Version 1.0 (12/22/2008)
* @requires jQuery v1.2.6 or later
*
* Example at: http://jonpauldavies.github.com/JQuery/Pager/PagerDemo.html

* Read the related blog post and contact the author at http://www.j-dee.com/2008/12/22/jquery-pager-plugin/
*
* 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.

var destPage = 1;
// work out destination page for required button type

if (buttonLabel == "first" || buttonLabel == "上一页") {
pagenumber <= 1 ? $Button.addClass('pgEmpty') : $Button.click(function() { buttonClickCallback(destPage); });
}
else {
pagenumber >= pagecount ? $Button.addClass('pgEmpty') : $Button.click(function() { buttonClickCallback(destPage); });
}
return $Button;
} // pager defaults. hardly worth bothering with in this case but used as placeholder for expansion in the next version
$.fn.pager.defaults = {
pagenumber: 1,
pagecount: 1
}; })(jQuery);
直接将这两个文件保存在自己的项目之中使用即可。
而在HTML中：
<h1 id="result">Click the pager below.</h1>
<div id="pager"></div>
<script type="text/javascript" language="javascript">
//pagenumber 为当前页码
//pagecount 为显示页数
//PageClick 为回调函数
//pageclickednumber 为点击页码
$(document).ready(function() {
$("#pager").pager({ pagenumber: 1, pagecount: 10, buttonClickCallback: PageClick });
}); PageClick = function(pageclickednumber) {
$("#pager").pager({ pagenumber: pageclickednumber, pagecount: 10, buttonClickCallback: PageClick });
$("#result").html("Clicked Page " + pageclickednumber);
} </script>
结果：
这样，简单的分页功能就完成了。
