普通分页
HTML
<div>
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></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></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'
