JSP页面2种简单的分页形式

JSP页面2种简单的分页形式，写下来以做备忘，欢迎各位建议或批评。第一种使用js，第二种直接用url地址。第一种较好。

第一种形式：

<!--分页信息展示 start-->
        <div class="page-generation" id="marketingpage"> 
         共${info_totalCount}条数据.    
         <a href="javascript:go('${info_currentPage -1}');">上一页</a>
         <c:forEach begin="1" end="${info_pageNumShown}" var="tt">
          <c:choose>
           <c:when test="${tt==info_currentPage}">
            <font color="red">${tt}</font>
           </c:when>
           <c:otherwise>
            <a href="javascript:go('${tt }');">${tt}</a>
           </c:otherwise>
          </c:choose>
         </c:forEach>
         <a href="javascript:go('${info_currentPage +1 }');">下一页</a>
         <a href="javascript:go(${info_pageNumShown });">尾页</a>
        </div>
<!--分页信息展示 end-->

 js代码：

 

<script>
//分页去向
function go(num)  
{    
	var pageNumShown = '${info_pageNumShown}' ;
	pageNumShown = parseInt(pageNumShown);
	var searchContent = $("#search_result_box_textarea").val();
	if(num<=0)  
	{  
		alert('当前已是首页');  
		return;  
    }  
	if(num>pageNumShown)  
	{  
		alert('当前已是尾页');  
		return;  
	}  
	var url = window.location;  
	var pos = String(url).indexOf("pageNum");    //查看是否存在pageNum页数参数  
	if(pos=="-1")  
	{  
        window.location.replace(url+'?pageNum='+num+"&searchContent="+searchContent) ;   //不存在则添加,值为所点击的页数  
	}  
 	else  
	{  
       	var ui = String(url).substring(0,pos);             
        window.location.replace(ui+'pageNum='+num+"&searchContent="+searchContent);      //存在,则刷新pageNum参数值  
    }  
}   
</script>
