求解:jsp页面 中文乱码的问题

jsp页面通过js代码判断之后alert出来的中文是乱码,编码都是用的UTF-8,请问要怎么解决?

21个回答

假如你的这样的汉字有点多,你这样,你把所有汉字一句句的放在放在一个properties的文件里面,用这个工具统一转,方法如下:
在dos进入你的properties所在的文件夹,输入命令 [code="java"] native2ascii -encoding UTF-8 ApplicationResources_zh_src.properties ApplicationResources_zh.properties[/code]

前者是你原始的,后者是你转化后的。

然后你懂的,你copy到你项目中。

再搞不定 我去跳黄浦江。

jsp文件本身是否是utf-8编码?
content="text/html; charset=utf-8" 是否加上了?

其他地方没有乱码吧 只是页面出现的?
你能贴出你代码吗 我看看。

Myeclipse中
General-->Editors-->Text Editors-->spelling里面也有设置编码的 你也可以看一下。

要不也试试 把 contentType 换成
contentType="text/html;charset=UTF-8"

你是指 myalert() 方法么?没见你调用这个方法啊。何时调用这个方法呢?这样也让我们好实验一下啊

右击页面 点击最下面的Preference。

那你说一下是触发的哪个JS代码弹出的对话框显示的乱码吧

用过滤器
在包package filters 中创建SetCharacterEncodingFilter.java 代码如下
然后在配置文件中
[code="java"]

/**

  • Example filter that sets the character encoding to be used in parsing the

  • incoming request, either unconditionally or only if the client did not
  • specify a character encoding. Configuration of this filter is based on
  • the following initialization parameters:
    • encoding - The character encoding to be configured
    • for this request, either conditionally or unconditionally based on
    • the ignore initialization parameter. This parameter
    • is required, so there is no default.
    • ignore - If set to "true", any character encoding
    • specified by the client is ignored, and the value returned by the
    • selectEncoding() method is set. If set to "false,
    • selectEncoding() is called only if the
    • client has not already specified an encoding. By default, this
    • parameter is set to "true".
    *

    Although this filter can be used unchanged, it is also easy to

    subclass it and make the selectEncoding() method more intelligent about what encoding to choose, based on characteristics of the incoming request (such as the values of the Accept-Language and User-Agent headers, or a value stashed in the current user's session. * @author Craig McClanahan @version $Revision: 1.1 $ $Date: 2008/03/24 02:33:46 $ */

    然后在web.xml中配置一下

    <!-- 定义字符编码转换 -->

    Set Character Encoding
    filters.SetCharacterEncodingFilter

    encoding
    gb2312


    ignore
    true


    [/code]

    这样就应该没问题了

    你把你调用的那个文件都这样页面编码一下。

    还有 不知道你这样改了没有 contentType="text/html;charset=UTF-8"
