<!-- 
路由使用：

  //pageCurrent  当前页数
  var pager = {
  };
  pager.pagePath = 'lostfound-manager?';
  pager.pageSize = 10;
  pager.pageCurrent = 1;
  if (current == undefined) {
    pager.pageCurrent = 1;
  } else {
    pager.pageCurrent = current;
  }

 pager.maxNum = retData.length;
 pager.pageCount = parseInt(Math.ceil(parseFloat(pager.maxNum) / parseFloat(pager.pageSize)));  //计算总页数


  返回 req.pager = pager;
