jstl标签<c:url>查询分页时拼接参数的用法

先上代码:

<%@ page language="java" contentType="text/html; charset=UTF-8"pageEncoding="UTF-8"%><%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%><%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt"%><%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%><c:set var="ctx">${ pageContext.request.contextPath }</c:set><html><head><title>号码段管理</title></head><body><content tag="breadcrumb-list"><li class="active">号码段管理</li></content><div class="panel panel-default"><div class="panel-heading"><span class="h3"><i class="icon-table icon-large"></i> 号码段管理</span><div class="space-4"></div><form class="form-inline" role="form" id="search-form"><div class="form-group"><label for="q-form-username">区域号</label> <input type="text"class="form-control" id="seg_code" name="seg_code"value="${param.seg_code }" placeholder="区域号"></div><div class="form-group"><label for="q-form-username">号段</label> <input type="text"class="form-control" id="seg_num" name="seg_num"value="${param.seg_num }" placeholder="号段"></div><button type="submit" class="btn btn-info btn-sm"><i class="icon-search"></i> 查询</button><button id="save-btn" type="button" onclick="save()" class="btn btn-warning btn-sm"><span class="glyphicon glyphicon-plus"></span> 新增</button></form></div><div class="table-responsive"><table id="mainTable"class="table table-striped table-bordered table-hover"><thead><tr><th class="center">区域号</th><th>号段</th><th>省</th><th>市</th><th>运营商</th><th>操作</th></tr></thead><tbody><c:forEach items="${page.list}" var="item"><tr><td class="center">${item.segCode }</td><td>${item.segNum }</td><td>${item.provinceName }</td><td>${item.cityName }</td><td><c:if test="${item.operator.value==1 }">${item.operator.desc }</c:if> <c:if test="${item.operator.value==2 }">${item.operator.desc }</c:if> <c:if test="${item.operator.value==3 }">${item.operator.desc }</c:if></td><td><a class="green"href="${ctx }/mobileseg/modifyskip/${item.id}"> <iclass="icon-pencil bigger-130"></i></a> <a class="red"onclick="javascript:$.opRecord('确认删除号码段？', '${ctx }/mobileseg/delete/${item.id }');"><i class="icon-trash bigger-130"></i></a></td></tr></c:forEach></tbody></table><div class="text-center"><!-- 注意这块代码 --><c:url var="url" value=""><c:param name="seg_code">${param.seg_code }</c:param><c:param name="seg_num">${param.seg_num }</c:param></c:url><jsp:include page="/WEB-INF/jsp/pager/simple.jsp"><jsp:param name="url" value="${url }" /></jsp:include></div></div></div><script>var flushMessage = '${message}';</script><content tag="javascript-block"> <script>jQuery(function($) {//操作消息if (flushMessage) {$.showTip("info", flushMessage);}$.showLeftMenu("${ctx}/mobileseg/index");});function save(){window.location.href="${ctx}/mobileseg/saveskip";}</script></content></body></html>

注意上面<div class="text-center">中的代码
<c:url>中设置了两个<c:param>参数，这两个参数为上面查询条件，区域号和号段，下面<jsp:include>中引入的simple.jsp为分页界面(用来显示上一页、下一页，页码)，这样设置的好处是，点击查询按钮时，form表单提交到默认的Url路径下，查询的参数自动拼在url后面，这样点击下一页时，pageNum和查询条件可以直接拼在url后面，从而不会让查询参数遗失导致分页显示内容错误。
