JQuery实现分页功能

使用JQuery实现分页功能。

1、分页栏HTML码

<div class="g-cf g-pagerwp">    <div style="visibility:hidden" class="g-pager">    </div></div>

2、 CSS样式文件

.g-cf:after {clear: both;content: "";display: table;}.g-cf {zoom:1;}/*分页*/.g-pager{ text-align:center; color: #111111; font: 12px/1.5em Arial,Tahoma;  float: right;}.g-pager a,.g-pager input{ cursor:pointer; border:solid 1px #0F71BE; padding:1px 4px; color:#0F71BE; margin:0 2px; vertical-align:middle; }.g-pager a.cur,.g-pager a:hover{ background-color:#0F71BE; color:#fff}.g-pager a.no{ border-color:#A3A3A3; color:#A3A3A3; background-color:#E4F2F9}.g-pager span{ margin-right:10px; }.g-pager input{ cursor:default; width:28px; padding:1px 2px; }.g-pagerwp{ height:23px; line-height:23px;padding:5px; margin-bottom:10px; border: 1px solid #DDDDDD;}.g-pagerwp .g-btn{ vertical-align:top}

3、JS脚本文件

3.1 引用JQuery和分页脚本

<script src="/js/common/jquery-1.6.2.js" type="text/javascript"></script><script src="/js/jquery.PageBar.js" type="text/javascript"></script>

3.2 编写jquery.PageBar.js脚本

/**************************///JQuery分页栏/**************************/$.fn.pageBar = function(options) {    var configs = {        PageIndex: 1,        PageSize: 15,        TotalPage: 0,        RecordCount: 0,        showPageCount: 4,        onPageClick: function(pageIndex) {            return false;   //默认的翻页事件        }    }    $.extend(configs, options);    var tmp = "",    i = 0,    j = 0,    a = 0,    b = 0,    totalpage = parseInt(configs.RecordCount / configs.PageSize);    totalpage = configs.RecordCount % configs.PageSize > 0 ? totalpage + 1 : totalpage;    tmp += "<span>总记录数：" + configs.RecordCount + "</span > ";    tmp += " <span>页数：" + totalpage + "</span>";    if (configs.PageIndex > 1) {        tmp += "<a><</a>"    } else {        tmp += "<a class=\"no\"><</a>"    }    tmp += "<a>1</a>";    if (totalpage > configs.showPageCount + 1) {        if (configs.PageIndex <= configs.showPageCount) {            i = 2;            j = i + configs.showPageCount;            a = 1;        } else if (configs.PageIndex > totalpage - configs.showPageCount) {            i = totalpage - configs.showPageCount;            j = totalpage;            b = 1;        } else {            var k = parseInt((configs.showPageCount - 1) / 2);            i = configs.PageIndex - k;            j = configs.PageIndex + k + 1;            a = 1;            b = 1;            if ((configs.showPageCount - 1) % 2) {                i -= 1            }        }    }    else {        i = 2;        j = totalpage;    }    if (b) {        tmp += "..."    }    for (; i < j; i++) {        tmp += "<a>" + i + "</a>"    }    if (a) {        tmp += " ... "    }    if (totalpage > 1) {        tmp += "<a>" + totalpage + "</a>"    }    if (configs.PageIndex < totalpage) {        tmp += "<a>></a>"    } else {        tmp += "<a class=\"no\">></a>"    }    tmp += "<input type=\"text\" /><a>Go</a>"    var pager = this.html(tmp)    var index = pager.children('input')[0]    pager.children('a').click(function() {        var cls = $(this).attr('class');        if (this.innerHTML == '<') {            if (cls != 'no') {                configs.onPageClick(configs.PageIndex - 2)            }        } else if (this.innerHTML == '>') {            if (cls != 'no') {                configs.onPageClick(configs.PageIndex)            }        } else if (this.innerHTML == 'Go') {            if (!isNaN(index.value)) {                var indexvalue = parseInt(index.value);                indexvalue = indexvalue < 1 ? 1 : indexvalue                indexvalue = indexvalue > totalpage ? totalpage : indexvalue                configs.onPageClick(indexvalue - 1)            }        } else {            if (cls != 'cur') {                configs.onPageClick(parseInt(this.innerHTML) - 1)            }        }    }).each(function() {        if (configs.PageIndex == parseInt(this.innerHTML)) {            $(this).addClass('cur')        }    })} 

3.3 初始化使用

$(document).ready(function() {    //设置分页信息    var pageOptions = {        AllowPaging: true,        PageIndex: 1,       //设置当前页码        PageSize: 15,       //设置分页大小        RecordCount: 1092,  //设置数据总数        TotalPage: 73,      //设置总页数        showPageCount: 4,        onPageClick: function(pageIndex) {        alert("您点击了第" + parseInt(pageIndex + 1) + "页");    //自定义您的翻页事件            return false;        }    }    //初始化分页栏    $('.g-pagerwp .g-pager').css('visibility', 'visible').pageBar(pageOptions);    })
