如何在JS中翻译字符串 [英] How to translate strings in JS

问题描述

我有一个项目，我想将其翻译成多种语言的PHP部分我使用Zend Frameworks Zend_Translate和GetText。现在我也要翻译JS部分。

I have a project which I want to translate into multiple languages for the PHP Part I use Zend Frameworks Zend_Translate with GetText. Now I want to translate the JS part too.

我正在使用jQuery JS Framework，并且很想听听你对JS文件翻译的看法

I am using the jQuery JS Framework and would love to hear your thoughts on translation for JS files

推荐答案

我已成功使用GetText在三个项目中翻译JavaScript文件。

I have successfully used GetText for translation of JavaScript files in three projects.

当然GetText本身不支持JavaScript，JavaScript也不支持GetText。我的解决方案如下。

Of course GetText natively doesn't support JavaScript and JavaScript also doesn't support GetText. My solution has been the following.

• 在JavaScript中我用 gettext（你的文字在这里）环绕可翻译的字符串。


• 然后我有一个脚本从JavaScript文件中提取字符串并创建一个C文件，因为gettext支持C.


• 然后我在生成的C文件和项目中的任何其他文件上使用 xgettext 来生成POT和PO文件。

• In JavaScript I surround translatable strings with gettext("your text here").
• Then I have a script that pulls the strings out of JavaScript files and creates a C file, because C is supported by gettext.
• Then I use xgettext on the generated C files and on any other files in my project to produce POT and PO files.

翻译PO文件后，我必须将翻译恢复为JavaScript ...

After translating PO files, I have to get the translations back to JavaScript...

• 我再次解析JavaScript文件，记住可翻译字符串的列表，然后是每个语言环境：


• 使用支持GetText的语言（在我的情况下是PHP）我翻译所有字符串和输出JavaScript文件。

例如爱沙尼亚语的语言环境文件（例如 et_EE.js ）可能如下所示：

For example a locale file for Estonian (e.g. et_EE.js) might look like this:

var LOCALE = {
  "Hello": "Tere",
  "My name is %s": "Minu nimi on %s",
  "Enter your credit card number": "Sisesta oma krediitkaardi number"
};

function gettext(string) {
  return LOCALE[string] ? LOCALE[string] : string;
}

根据所选的区域设置，您可以包含 et_EE。 js 或 en_US.js 或...

Depending on the selected locale you either include et_EE.js or en_US.js or ...

en_US.js 可能只包含以下内容：

en_US.js will probably contain just the following:

function gettext(string) {
  return string;
}

ngettext（），但你应该得到一般的想法。

A bit trickier for ngettext(), but you should get the general idea.

最棒的是我可以使用所有已有的gettext工具。特别是当我在PHP和JavaScript中都有可翻译的文本时 - 我可以使用相同的工具来翻译它们，并确保在JavaScript和PHP中以相同的方式翻译相同的字符串。

The great thing is that I can use all the gettext tools already available. Especially when I have translatable texts in both PHP and JavaScript - I can use the same tool for translating both of them and also ensure that the same string is translated the same way both in JavaScript and PHP.

注意：如果您没有使用JavaScript密集型网络应用，那么在首先使用JavaScript创建网页内容之前，您应该三思而行。

NOTE: If you aren't dealing with a JavaScript-intensive web-app, you should think twice before having page content created by JavaScript in the first place.
