第一种设置basePath的方法

要求每个页面中都设置

<%

String path = request.getContextPath();

String basePath =request.getScheme()+"://"+request.getServerName()+":"

+request.getServerPort()+path+"/";

%>

<head>
<base href="<%=basePath%>">

<title>管理员界面</title>

<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">


</head>

<%= path%><br/>

<%= basePath%><br/>

/Web_Servlet_JSP_MySql_Tomcat_Demo

http://localhost:8080/Web_Servlet_JSP_MySql_Tomcat_Demo/

JSP页面：

<div>

<a href="user/normal/servlet/loginOutUser">-注销-</a>

<a href="jsp/modify_password.jsp">-修改密码-</a>

</div>

<div>

<div>

<span style="color:red;font-weight:bold">

<%

if(request.getAttribute("tips")!=null){

out.println(request.getAttribute("tips")+"<br/>");

}

%>

</span>

</div>

<form method="post" action="user/manage/servlet/deleteUser">

....

</form>

第二种 设置basePath的方法

设置一个common.jsp

每个页面都引用这个jsp

common.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>

<c:set var="basePath" scope="request">${pageContext.request.contextPath}</c:set>

<%
response.setHeader("Cache-Control","no-catch");
response.setHeader("Pragma","no-catch");
response.setDateHeader("Expires",0);

%>

包含页面：

<%@ include file="/WEB-INF/jsp/global/jsp/common.jsp" %>

使用basePath包含资源：

<script type="text/javascript" src="${basePath}/js/jquery-easyui-1.4.3/jquery.min.js" charset="utf-8"></script>

<script type="text/javascript" src="${basePath}/js/print/jquery.PrintArea.js" charset="utf-8"></script>

<script type="text/javascript" src="${basePath}/js/jquery-easyui-1.4.3/jquery.easyui.min.js" charset="utf-8"></script>

<link rel="stylesheet" type="text/css" href="${basePath}/js/jquery-easyui-1.4.3/themes/default/easyui.css">

<link rel="stylesheet" type="text/css" href="${basePath}/js/jquery-easyui-1.4.3/themes/icon.css" >

<script type="text/javascript" src="${basePath}/js/jquery-easyui-1.4.3/locale/easyui-lang-zh_CN.js" charset="utf-8"></script>

JQuery

$("#del").click(function(){

var check=[];

$("input[name='handle']:checked").each(function(){

check.push($(this).val());

});

var str=check.toLocaleString();

if(check.length==0){

alert("请选择删除的选项");

return;

}

if(confirm("确定删除选择项吗?")==false)

{

return;

}

$.post("${basePath}/pay/yncConsumer_delConsumer.action",{"ids":str},function(data){

if(data.map=='success'){

location.reload();

}else{

alert("系统错误,删除失败!");

}

},"json");

});
