jQuery_pager.js分页

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{

    border:1px solid #eee;

 * jQuery pager plugin

 * Version 1.0 (12/22/2008)

 * @requires jQuery v1.2.6 or later

 *

 * 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.

    $.fn.pager = function(options) {

        var opts = $.extend({}, $.fn.pager.defaults, options);

        return this.each(function() {

        return $pager;

    }

    // renders and returns a 'specialized' button, ie 'next', 'previous' etc. rather than a page number button

    function renderButton(buttonLabel, pagenumber, pagecount, buttonClickCallback) {

        var $Button = $('<li class="pgNext">' + buttonLabel + '</li>');

        var destPage = 1;

        // work out destination page for required button type

        switch (buttonLabel) {

            case "first":

                destPage = 1;

                break;

            case "上一页":

                destPage = pagenumber - 1;

                break;

            case "下一页":

                destPage = pagenumber + 1;

                break;

            case "last":

                destPage = pagecount;

                break;

        }

        // disable and 'grey' out buttons if not needed.

        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。
