将语言文件放到webapp的i18n目录下
i18n_chinese.json类似内容如下
{
"code":"邮编",
"contactTelephone":"联系电话",
"email":"邮箱"}
i18n_english.json
{
"code":"Code",
"contactTelephone":"ContactTelephone",
"email":"Email"}
想要切换语言 给标签添加i18n属性
如<li i18n=" code">邮编</li>
我是通过Cookie方式绑定当前语言的，提取language.jsp如下：
<!DOCTYPE html>
<%@page language="Java"pageEncoding="UTF-8"%>
<script type="text/JavaScript"src="${ctx}/anfangyun/js/jquery.i18n.min.js"></script>
<script>
function setCookieLanguage(name,value) {
document.cookie = name + ‘=‘ + value ;
};
function getCookieLanguage(name) {
vararr = document.cookie.split(‘; ‘);
for(vari = 0; i < arr.length; i++) {
var arr1 = arr[i].split(‘=‘);
if (arr1[0] == name) {
return arr1[1];
}
}
return‘‘;
};
$(function(){
//切换语言begin
//获取浏览器默认语言
var languageType =navigator.browserLanguage?navigator.browserLanguage:navigator.language;
if (languageType.indexOf(‘zh‘)>-1 &&getCookieLanguage("languageCookie")==""){
$("[i18n]").i18n({defaultLang:"chinese"});
}
if (languageType.indexOf(‘en‘)>-1 &&getCookieLanguage("languageCookie")==""){
$("[i18n]").i18n({defaultLang:"english"});
}
if (languageType.indexOf(‘ru‘)>-1 &&getCookieLanguage("languageCookie")==""){
$("[i18n]").i18n({defaultLang:"russian"});
}
//切换为中文 - 按钮
$("#chinese").click(function() {
$("[i18n]").i18n({defaultLang:"chinese"});//选择文件i18n_chinese.json
setCookieLanguage("languageCookie","chinese");
});
//切换为英文 - 按钮
$("#english").click(function() {
$("[i18n]").i18n({defaultLang:"english"});//选择文件i18n_english.json
setCookieLanguage("languageCookie","english");
});
//切换为俄文 - 按钮
$("#russian").click(function() {
$("[i18n]").i18n({defaultLang:"russian"});//选择文件i18n_russian.json
setCookieLanguage("languageCookie","russian");
});
//点击后有cookie，定位选择文件名字
if (getCookieLanguage("languageCookie").indexOf("chinese")>-1){
$("#chinese").addClass(‘cur‘);
$("[i18n]").i18n({defaultLang:"chinese"});
//更改头部图片
$(".afy_hd_capt").css("background-image","url(${ctx}/anfangyun/images/afy_hd_capt.png)");
$(".afy_hd_dire").css("background-image","url(${ctx}/anfangyun/images/afy_hd_dire.png)");
}
if (getCookieLanguage("languageCookie").indexOf("english")>-1){
$("[i18n]").i18n({defaultLang:"english"});
}
if (getCookieLanguage("languageCookie").indexOf("russian")>-1){
$("[i18n]").i18n({defaultLang:"russian"});
}
//切换语言end
});
