javascript多语言实现

本文为自己总结，如有不对之处，不吝赐教

在jsp中获取本地浏览器语言环境，然后利用定义js的全局变量来实现相应的中英文语言，jsp代码如下：

<%@ page language="java" errorPage="/error.jsp" pageEncoding="UTF-8" contentType="text/html;charset=utf-8"%>
<%@ page import="java.util.Locale" %>

<%
Locale request_lo = request.getLocale();
String type = "";
//判断，如果请求来自中文的语言环境浏览器，就显示中文
if(request_lo.equals(Locale.CHINA)){
type = "language_zh";
}

//判断，如果请求来自美国英语的语言环境浏览器，就显示英语
if(request_lo.equals(Locale.US)){
type = "language_en";
}
%> 

var type = "<%=type%>";

if(type == "language_zh"){

var firstpage_sendmsg_subject = "主题不能为空！";

}

if(type == "language_en"){

var firstpage_sendmsg_subject = "Subject cannot be empty!";

}
