JavaScript 和多语言最佳实践

使用JavaScript编写多语言应用程序时，有一些最佳实践可以帮助我们提高代码质量和可维护性。本文将介绍其中一些最重要的实践，并提供相应的案例代码。

javascript
var myVariable = 10;

javascript
// Translate the label text into French
var label = "Hello World"; // English
// var label = "Bonjour le monde"; // French

javascript
// English module
var en = {
  greeting: "Hello",
  farewell: "Goodbye"
};
// French module
var fr = {
  greeting: "Bonjour",
  farewell: "Au revoir"
};

javascript
// Language pack for English
var en = {
  greeting: "Hello",
  farewell: "Goodbye"
};
// Language pack for French
var fr = {
  greeting: "Bonjour",
  farewell: "Au revoir"
};
// Function to get the translation based on language code
function getTranslation(languageCode, key) {
  if (languageCode === "en") {
    return en[key];
  } else if (languageCode === "fr") {
    return fr[key];
  }
}
// Example usage
var languageCode = "en";
var greeting = getTranslation(languageCode, "greeting");
console.log(greeting); // Output: "Hello"

javascript
// Language pack for English
var en = {
  greeting: "Hello, {name}!",
  farewell: "Goodbye, {name}!"
};
// Function to generate formatted text
function formatText(text, variables) {
  return text.replace(/{(\w+)}/g, function(match, key) {
    return variables[key];
  });
}
// Example usage
var languageCode = "en";
var greeting = getTranslation(languageCode, "greeting");
var formattedGreeting = formatText(greeting, { name: "John" });
console.log(formattedGreeting); // Output: "Hello, John!"
