jquery.pager.js
Java 代码
- /*
- * 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

- * 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.
