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', '"htmlcode">

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