Ajax实现搜索功能的分页

<a class="btn-lit" type="submit" onclick="searchresult(on())"><span>搜索</span></a>
//嵌套函数，用来情空最大页数和当前页数

<div id="fenye" class="cnt-wp" style="display: none;">
  <span id="pageajax"> 页次：{$pagefunc[1]}/{$pagefunc[4]} 每页22总数{$pagefunc[2]}</span>
  <a class="btn-lit" onclick="pageajaxfirst()"><span>首页</span></a>
  <a class="btn-lit" onclick="pageajaxprev()"><span>上一页</span></a>
  <a class="btn-lit" onclick="pageajaxnext()"><span>下一页</span></a>
  <a class="btn-lit" onclick="pageajaxend()"><span>尾页</span></a>
  <input type="text" name="pagetiao" id="pagetiao" style="width: 35px;height: 20px;margin-top:-2px;">
  <a onclick="tiao()" class="btn-lit"><span>跳转</span></a>
