使用JQuery实现分页功能。

**1、分页栏HTML码**

**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**

**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);    
    })
