使用Layui表格实现后台分页的方法

<table class="<a style='color:#f60; text-decoration:underline;' href="https://www.php.cn/zt/18036.html" target="_blank">layui</a>-table" lay-data="{width: 892, height:332,url:&#39;&#39;, page:true, id:&#39;idTest&#39;}" lay-filter="demo">
  <thead>
    <tr>
      <th lay-data="{type:&#39;checkbox&#39;, fixed: &#39;left&#39;}"></th>
      <th lay-data="{field:&#39;id&#39;, width:80, sort: true, fixed: true}">id</th>
      <th lay-data="{field:&#39;menubarid&#39;, width:80}">菜单id</th>
      <th lay-data="{field:&#39;name&#39;, width:80, sort: true}">菜名</th>
      <th lay-data="{field:&#39;price&#39;, width:80}">价格</th>
      <th lay-data="{field:&#39;status&#39;, width:160}">状态</th>
      <th lay-data="{fixed: &#39;right&#39;, width:178, align:&#39;center&#39;, toolbar: &#39;#barDemo&#39;}"></th>
    </tr>
  </thead>
</table>

int page = Integer.parseInt(request.getParameter("page"));
int limit = Integer.parseInt(request.getParameter("limit"));	
int count = menuDao.searchcount();             // 查找数据条数
int page_temp = page;
int limit_temp = limit;
if (count < page * limit) {
	limit = count - (page - 1) * limit;
}
page = (page_temp - 1) * limit_temp;

 select  count(*) from menu 
select * from menu limit ?,?

String layjson ="{\"code\":0,\"msg\":\"\",\"count\":"+getcount()+",\"data\":["+data+"]}";
