Internet Explorer和JSP中的基本URL | Explorer和JSP中的基本URL

本文介绍了Internet Explorer和JSP中的基本URL的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

Internet Explorer不支援HTML 使用< c： url> 来自JSTL的标记，以引用JSP文件中的CSS / JavaScript资源。通过这样做，您可以确保CSS / JavaScript资源始终相对于应用程序上下文（上下文路径）被引用。

示例

index.jsp：

 <％@ page language =javacontentType =text / html; charset = UTF-8pageEncoding =UTF-8％> 
 <！DOCTYPE html> 
< html> 
< head> 
< title> Some Title< / title> 
< meta http-equiv =Content-Typecontent =text / html; charset = UTF-8> 
< link type =text / css =stylesheethref =< c：url value =/ css / main.css/> /> 
< script type =text / javascriptsrc =< c：url value =/ js / utils.js/>>< / script> 
< script type =text / javascriptsrc =< c：url value =/ js / jquery-1.8.3.js/>>< / script> 
< / head> 
< body> 
 ... 
< / body> 
< / html>

Internet Explorer doesn't support HTML <base> tag and even other browsers do, there are some problems when redirect takes place inservletsto some.jsppages for examplerequest dispatching.`

It's feasible to add ${pageContext.request.contextPath} with each URLnor request.getServletPath()

JSP relative links for CSS and images with servlets forwarding may change things a lot. This link : Browser can't access/find relative resources like CSS, images and links when calling a Servlet which forwards to a JSP

Is there a better approach with JSP / servlets or it's just an IE issue?
Link : HTML <base> TAG and local folder path with Internet Explorer

And if it is an IE issue:
1. how to fix the IE issue as the above post is unable to give a valid answer?
2. how to solve it with JSP / servlets?

My website is now showing CSS and images.
E.g. HTML output is:

<base href="http://localhost:8080/Alpinema/" /> is not working for
<link media="all" rel="stylesheet" type="text/css" href="css/all.css">

It works in other browsers like Firefox and Chrome.

My JSP code portion:

<head>
    <base href="${fn:substring(url, 0, fn:length(url) - fn:length(uri))}${req.contextPath}/" />
    <meta charset="utf-8">
    <title>Alpinema.com</title>
    <link media="all" rel="stylesheet" type="text/css" href="css/all.css">
   /css?family=Merriweather|PT+Sans:700|Nobile:400italic' rel='stylesheet' type='text/css'>
</head>

解决方案

Use <c:url> tag from JSTL to reference CSS/JavaScript resources inside my JSP files. By doing so you can be sure that the CSS/JavaScript resources are referenced always relative to the application context (context path).

Example

index.jsp:

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<!DOCTYPE html>
<html>
<head>
  <title>Some Title</title>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  <link type="text/css" rel="stylesheet" href="<c:url value="/css/main.css" />" />
  <script type="text/javascript" src="<c:url value="/js/utils.js" />"></script>
  <script type="text/javascript" src="<c:url value="/js/jquery-1.8.3.js" />"></script>
</head>
<body>
...
</body>
</html>
