[英]Eclipse javascript character encoding
I'd like to display some language specific characters from javascript but I can't. 我想显示来自javascript的一些特定于语言的字符,但不能。
My app is a Java webapp and the front end is jQuery. 我的应用程序是Java webapp,前端是jQuery。 All the characters that are sended from the server - in a JSP or with AJAX - are displayed properly.
从服务器发送的所有字符-在JSP中或通过AJAX-均正确显示。 When I want to display some text hardcoded in to the javascript file it's broken.
当我想显示一些硬编码到javascript文件中的文本时,它已损坏。
I'm using Eclipse. 我正在使用Eclipse。 In the JSP's header I use:
在JSP的标头中,我使用:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
I've tried this (charset in the script element) too: 我也尝试过这个(脚本元素中的字符集):
<script type="text/javascript" charset="utf-8"><c:import url="/JS/mainJS.js" /></script>
In my Eclipse I've set the project properties / text file encoding to UTF-8 AND I've checked the JS files' resource properties / text file encoding that is UTF-8 too. 在Eclipse中,我已经将项目属性/文本文件编码设置为UTF-8,并且我还检查了JS文件的资源属性/文本文件编码也为UTF-8。
But when I try this: 但是当我尝试这个:
$.test = function(){
var s = "éééáááűűűű";
alert(s);
}
I get: 我得到:
éééáááűűűű
The strange thing is that: When I try in a separate html file (in the same project), It's working: 奇怪的是:当我尝试一个单独的html文件(在同一项目中)时,它正在工作:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>Test</title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<style type="text/css">
body {background: #c0c0c0;}
</style>
<script type="text/javascript">
$(document).ready(function(){
var s = "éááűűúúú";
$("#console").text(s);
alert(s);
})
</script>
</head>
<body>
<div id="console"></div>
</body>
</html>
Even if I DO NOT use any content type and page encoding settings. 即使我不使用任何内容类型和页面编码设置。
What is the problem? 问题是什么? What shall I do?
我该怎么办? (I'm using Apache Tomcat integrated in Eclipse)
(我正在使用集成在Eclipse中的Apache Tomcat)
Thanks in advance! 提前致谢!
The c:import
uses the server platform default encoding if the encoding is absent in the response header of the request. 如果请求的响应标头中不存在
c:import
使用服务器平台默认编码。 Rather just use src
attribute instead. 而是只使用
src
属性。 The webbrowser is smarter in this. Web浏览器在这方面更聪明。
<script type="text/javascript" src="/JS/mainJS.js"></script>
(if necessary remove the leading slash if you're running on a fixed context instead of on domain root) (如果您是在固定上下文而不是域根目录上运行,则如有必要,请删除斜杠)
If you really, really need the c:import
for this (for which I honestly don't see any advantage in this particular situation), then you need to write a Filter
listening on /JS/*
which sets the appropriate Content-Type
header with the correct encoding on the response. 如果确实需要使用
c:import
(老实说,在这种情况下我看不到任何好处),那么您需要编写一个侦听/JS/*
的Filter
,它会设置适当的Content-Type
标头在响应上使用正确的编码。 This however won't work if it concerns an external URL, it's then the responsibility of the external server. 但是,如果它涉及外部URL,则无法使用,这是外部服务器的责任。
