javajsp分頁(yè)代碼 java做分頁(yè)

今天要寫一個(gè)java分頁(yè)的頁(yè)面，jsp頁(yè)面需要傳三個(gè)參數(shù)beginpage 和 endpage和當(dāng)前的頁(yè)數(shù)nowpage給action

nowpage 默認(rèn)是 request 作用范圍的 在作為 servlet類里 應(yīng)該 request.setRequest("nowpage",相應(yīng)大變量);

jsp 如何將查詢結(jié)果實(shí)現(xiàn)分頁(yè)，最好簡(jiǎn)單易懂…

jsp中分頁(yè)最快捷的辦法是用分頁(yè)組件：

分頁(yè)組件代碼使用taglib實(shí)現(xiàn)的：

%@ tag language="java" pageEncoding="UTF-8"%

%@ taglib uri="/WEB-INF/tld/c.tld" prefix="c"%

%@ attribute name="curIndex" type="java.lang.Long" required="true"%

%@ attribute name="pageSize" type="java.lang.Long" required="true"%

%@ attribute name="pagerRange" type="java.lang.Long" required="true"%

%@ attribute name="totalPage" type="java.lang.Long" required="true"%

%@ attribute name="formId" type="java.lang.String" required="true"%

%

long begin = Math.max(1, curIndex - pagerRange/2);

long end = Math.min(begin + (pagerRange-1),totalPage);

request.setAttribute("p_begin", begin);

request.setAttribute("p_end", end);

%

table class="pager"

tr

% if (curIndex!=1){%

tda href="javascript:gotoPage(1)"首頁(yè)/a/td

tda href="javascript:gotoPage(%=curIndex-1%)"上一頁(yè)/a/td

%}else{%

td class="disabled"a href="#"首頁(yè)/a/td

td class="disabled"a href="#"上一頁(yè)/a/td

%}%

c:forEach var="i" begin="${p_begin}" end="${p_end}"

c:choose

c:when test="${i == curIndex}"

td class="active"a href="#"${i}/a/td

/c:when

c:otherwise

tda href="javascript:gotoPage(${i})"${i}/a/td

/c:otherwise

/c:choose

/c:forEach

% if (curIndex!=totalPage){%

tda href="#"下一頁(yè)/a/td

tda href="#"末頁(yè)/a/td

%}else{%

td class="disabled"a href="javascript:gotoPage(%=curIndex+1%)"下一頁(yè)/a/td

td class="disabled"a href="javascript:gotoPage(%=totalPage%)"末頁(yè)/a/td

%}%

tda共${totalPage}頁(yè)/a/td

td class="input_li"跳轉(zhuǎn)到:input type="text" id="p_pageIndex" size="2" value="c:out value="${pageIndex}"/"/頁(yè) input type="button" id="gotoBtn" onclick="gotoPageByBtn()" value="GO"http://td

td class="input_li" 每頁(yè):

select id="p_pageSizeSelect" onchange="gotoPage(%=curIndex%)"

option value="10" c:if test="${pageSize==10}"selected/c:if10條/option

option value="20" c:if test="${pageSize==20}"selected/c:if20條/option

option value="50" c:if test="${pageSize==50}"selected/c:if50條/option

/select

/td

/tr

/table

jsp中使用方法：

%@ taglib uri="/WEB-INF/tld/c.tld" prefix="c"%

%@ taglib uri="/WEB-INF/tld/fmt.tld" prefix="fmt"%

%@ taglib tagdir="/WEB-INF/tags" prefix="tags"%

action代碼：

PageModel pageModel = new PageModel();

// 獲得當(dāng)前頁(yè)

if (page != 0) {

pageModel.setPage(page);

}

pageModel.setPageSize(10);// 設(shè)置頁(yè)面顯示最大 值

pageModel.setTotalCount(baseDAO.listAll("from Art where arttype.id=10 and mark=0 order by id desc")); // 數(shù)據(jù)總條數(shù)

pageModel.setNum(5); // 設(shè)置當(dāng)前頁(yè)的前后距離,/**前后各顯示5頁(yè)**/

// 通過當(dāng)前頁(yè)和

ListArt aboutList = baseDAO.listAll("from Art where arttype.id=10 and mark=0 order by id desc", pageModel.getPage(),pageModel.getPageSize());

pageModel.setItems(aboutList);

request.setAttribute("count", aboutList.size());// 放置在request中

request.setAttribute("pageModel", pageModel);

request.setAttribute("page", pageModel.getPage());
