f(page==1){
  sqlStr=sqlStr+" order by a.Id desc limit0,"+pageSize;
  // sqlStr=sqlStr+" order by Id desc "+pageSize;
  //sqlStr=sqlStr+" order by a.Id desc limit0,10"+pageSize;

  }else{

  sqlStr=sqlStr+"limit"+(recordCount-pageSize*page)+","+

  (recordCount-pageSize*(page-1));

  }

  }

limit0,10这里错了 limit和0之间加个空格
