我们正在创建我们的在线商店的国际版本，我的任务是解开所有javascript错误消息，因此它们以该网站上的相关语言显示。
我显然想做的是为所有网站保留相同的javascript集，但只是加载来自德语/法语/意大利语文本文件的一组错误消息。我认为这可能与单独的json文件有关，这些文件只包含一组纯文本错误消息。
有人能为这个问题提出最简单，最具扩展性的解决方案吗？感谢。

您拥有的一个选项是创建Javascript语言文件，并在Javascript文件之前包含正确的文件。在服务器端，所选语言是已知的，因此可以轻松地包含正确的文件。在语言文件中，您可以定义可在代码中使用的变量。
类似的东西：
<script type="text/javascript" src="lang_en.js" />
<script type="text/javascript" src="yourjavascript.js" />
lang_en.js可以是lang_de.js或服务器决定的任何内容。
在语言文件中你有类似的东西（简化的，全局的东西，只是想表明这个想法）：
var lang = {
ARE_YOU_SURE : 'Are you sure?',
...
};
在您的主要Javascript文件中，您可以执行以下操作：
alert(lang.ARE_YOU_SURE);

我有点解决了我如何检索消息并传入我自己的变量的问题。这是我构建的一个简单测试页面的代码：

<script type="text/javascript" src="http://media.topshop.com/javascript/wearwiths/lib/jquery/jquery.js"></script>
<script type="text/javascript" src="brand.js"></script>
<script type="text/javascript">
var msg, xVal = 2, yVal = 8, prodName = "Blue Skirt", msg_type = "information", lang = "eng";
$.ajax({
url: lang + '_messages.js',
dataType: 'script',
scriptCharset: 'utf-8',
success: function() {
console.log("The " + lang + " language file was loaded.");
msg = messages || {};
}
});
function translate(message, details) {
if(message.indexOf("{currency}") != -1) {
message = message.replace("{currency}", Arcadia.Brand.currency);
console.log(typeof Arcadia.Brand.currency);
}
if(message.indexOf("{val}") == -1) {
return message;
} else {
for (var i = 0; i < details.length; i++) {
message = message.replace("{val}", details[i]);
}
return message;
}
}
$(document).ready(function() {
var listItem, listIndex;
$('#item_list li a').click(function() {
listItem = $(this).parent();
listIndex = $('ul#item_list li').index(listItem);
toString(listIndex);
switch (msg_type) {
case "information":
$("p#error").text(translate(msg.information["mes_" + listIndex], [xVal, "14"]));
console.log(translate(msg.information["mes_" + listIndex], [xVal, "14"]));
break;
case "product_or_bundle":
$("p#error").text(translate(msg.product_or_bundle["mes_" + listIndex], [xVal, "14"]));
console.log(translate(msg.product_or_bundle["mes_" + listIndex], [xVal, "14"]));
break;
case "error":
$("p#error").text(translate(msg.error["mes_" + listIndex], [xVal, "14"]));
console.log(translate(msg.error["mes_" + listIndex], [xVal, "14"]));
break;
case "code":
$("p#error").text(translate(msg.code["mes_" + listIndex], [xVal, "14"]));
console.log(translate(msg.code["mes_" + listIndex], [xVal, "14"]));
break;
}
return false;
});
$('ul#message_select li a').click(function() {
msg_type = $(this).attr('href');
msg_type = msg_type.replace('#', "");
});
$('select#lang').change(function () {

我现在面临的问题是，法语和德语的外国语言字符都是胡说八道。这与字符集有关，但我在html和ajax调用中将字符集设置为utf-8，使用utf-8字符集指定js消息文件。任何想法如何克服这个？
为了完整起见，这里是英文版laguage消息，文件为eng_messages.js：

在纯JS中，你只能使用navigator.language上的粗分支
我建议配置httpd以提供基于Accept-Language的适当变体，而不是使其“无缝”
