后台返回的参数是当前页，总数量，list数据，搜索的字符串。

\#set($page\_size = 10)//一页大小  
\#set($page2 = $total/10)  
\#set($page1 = $total/10+1)  
\#if($total/10 ==0)//设置总页数  
\#if($total<10)  
\#set($page\_count = $page2+1)  
\#else  
\#set($page\_count = $page2)  
\#end  
\#else  
\#set($page\_count = $page1)    
\#end  
\#set($p\_page = $index)//当前页  
\#set($pre1\_page = $p\_page - 1)  
\#set($pre2\_page = $p\_page - 2)  
\#set($next1\_page = $p\_page + 1)  
\#set($next2\_page = $p\_page + 2)  
  
    <form action="/index/searchGift.htm" method="post">      
             搜索条件:<input type="text" name="str" value="$str" >    
             <input type="submit" value="搜索">  
    </form>    
      
    \#foreach($info in $list)  
       giftName:\[$info.giftName\]   giftPrice:\[$info.giftPrice\]   oneType:\[$info.oneType\]  twoType:\[$info.twoType\] <br>  
    \#end  
    <h2>\#if($page\_count > 1)  
             \#if($p\_page>1)  
              <a href="/index/searchGift.htm?pageindex=1&str=$str" >首页</a>  
                 <a href="/index/searchGift.htm?pageindex=$pre1\_page&str=$str">上页</a>  
             \#end  
             \#if($pre2\_page >=1)  
             <a href="/index/searchGift.htm?pageindex=$pre2\_page&str=$str">$pre2\_page</a>  
             \#end  
             \#if($pre1\_page >=1)  
             <a href="/index/searchGift.htm?pageindex=$pre1\_page&str=$str">$pre1\_page</a>  
             \#end  
             <a href="/index/searchGift.htm?pageindex=$p\_page&str=$str">$p\_page</a>  
             \#if($next1\_page <=$page\_count)  
             <a href="/index/searchGift.htm?pageindex=$next1\_page&str=$str">$next1\_page</a>  
             \#end  
             \#if($next2\_page <=$page\_count)  
             <a href="/index/searchGift.htm?pageindex=$next2\_page&str=$str">$next2\_page</a>  
             \#end  
             \#if($p\_page < $page\_count)  
              <a href="/index/searchGift.htm?pageindex=$next1\_page&str=$str">下页</a>  
              <a href="/index/searchGift.htm?pageindex=$page\_count&str=$str">尾页</a>  
             \#end  
        \#end  
             \#if($page\_count>0)  
                 当前第$p\_page页,共$page\_count页 <input type="text" id= "index" style="width:30px"><a href="\#" onClick="jump()">跳转</a>  
             \#else  
                 没有找到东西  
             \#end  
        </h2>  
          
<script>  
    function jump()\{  
      var page = document.getElementById("index").value;  
      if(page&&page>0&&page<=$page\_count)\{//有输入值，并且输入值在1到总页数之间才跳转。  
          window.location.href="/index/searchGift.htm?pageindex="+page+"&str=$str";  
      \}  
   \}  
</script>

效果为：

## 首页  上页 1 2 3 4 5 下页 尾页 当前第3页，共42页      跳转    ##
