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'
