本文实例为大家分享了jquery.pager.js分页实现代码，供大家参考，具体内容如下

jquery.pager.js：

/* 
* 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 
* 
* Copyright (c) 2008-2009 Jon Paul Davies 
* Dual licensed under the MIT and GPL licenses:

* http://www.gnu.org/licenses/gpl.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.
