爬虫:搜索结果要等待几秒之后才能出现,怎么爬取结果出现后的页面?

    data={'pageNo':'1','l':'20161019113636','gjfls':'1%3B2%3B3%3B4%3B5%3B6%3B7%3B8%3B9%3B10%3B11%3B12%3B13%3B14%3B15%3B16%3B17%3B18%3B19%3B20%3B21%3B22%3B23%3B24%3B25%3B26%3B27%3B28%3B29%3B30%3B31%3B32%3B33%3B34',

    html=session.get(url=url,headers=headers,params=data)
    print html.text

get_detailpage()

在填好搜索条件后,点击查询,页面上会显示要几秒后才能出结果,然后直接出现结果的页面。
爬取的网址是最后出现结果的网址,但爬取到的内容会出现:

<div class="cls"></div>
<div class="mainBox">
          <div class="jump">
          数据量巨大,正在努力查询中.... 预计<span id="jumpTo">5</span>秒后出结果  
        </div> 
        <div class="cls"></div>
</div> 

并不是想要的最终结果,怎么才能爬取到正确结果呢?不用selenium的话
