JavaScript简单分页，兼容IE6，~3KB

简介

兼容IE6+及现代浏览器的简单分页，支持同一页面多个分页。

使用

Browser

<link rel="stylesheet" href="css/GB-paging.css">
<script src="js/GB-paging.js"></script>

普通分页

HTML

<div id="gbpaging" class="gb-paging">

JS

gbPaging({
    total: 101,
    paramName: 'p',
    curPage: getPage('p', '#'),
    size: 5,
    prevText: '<',
    nextText: '>',
    pageInfo: '<b>{{currentPage}}</b>/<b>{{totalPages}}</b>',
    eventType: 'click'
});

同页面另一个分页

HTML

<div id="paging1" class="gb-paging"></div>

JS

gbPaging({
	eleId: 'paging1',
    total: 54,
    size: 10,
    prevText: false,
    nextText: false,
    paramName: 'p1',
    curPage: getPage('p1', '#'),
    pageInfo: false,
    eventType: 'click'
});

刷新带参数

HTML

<div id="paging2"  class="gb-paging"></div>

JS

gbPaging({
    eleId: 'paging2',
    total: 2500,
    paramName: 'page',
    curPage: getPage('page', '?type=1&name=2&'),
    goUrl: '?type=1&name=2&{{n}}'
});

辅助函数

function getPage(pname, other){
    var page = window.location.search.replace( other + pname + '=', '') || 1;
    return parseInt(page);
}

选项

• eleId 分页容器，仅支持ID，默认为： 'gbpaging'
• total: 总记录数
• paramName: 分页参数名 || 'p'
• curPage: 当前页码
• size: 每页记录数 || 10
• prevText: 上一页文案 || '上一页'，值为 false 不显示
• nextText: '下一页文案 || '下一页' 值为 false 不显示
• pageInfo: 分页信息，{{currentPage}}当前页码，{{totalPages}}总页数 || 当前第{{currentPage}}页/共{{totalPages}}页，值为 false 不显示
• eventType: 事件方式，'click' || 'link'
• goUrl： 链接URL，'?type=1&name=2&{{n}}' || ''，{{n}}为分页参数名+值，如：'p=1'
