如何在 reactjs 中实现本地化？

Question

We need to implement the localization in reactjs to define the string value(s). How can I implement that?

那里有一个 link https://www.npmjs.com/package/react-localization，但我没有得到正确的步骤来添加它。

我试过以下步骤：

我正在 ES6 中添加我的组件：

    class Home extends React.Component
    {
        constructor(props) {
            super(props);
        }
        render() {
            return (
              <Text>{strings.how}</Text>
             );
        }
    }

我已将本地化代码添加为：-

    import LocalizedStrings from 'react-localization';
    let strings = new LocalizedStrings({
        en:{
            how:"How do you want your egg today?",
            boiledEgg:"Boiled egg",
            softBoiledEgg:"Soft-boiled egg",
            choice:"How to choose the egg"
        },
        it: {
            how:"Come vuoi il tuo uovo oggi?",
            boiledEgg:"Uovo sodo",
            softBoiledEgg:"Uovo alla coque",
            choice:"Come scegliere l'uovo"
        }
    });

Now if you will see above :- {strings.how} I should able to get the strings value as it is defined in localization but I am not able to do it.

Yahoo 已经创建了一个用于在 React 中实现本地化的包，这可能就是您正在寻找的：https://github.com/yahoo/react-intl。它负责“日期、数字和字符串，包括复数和处理翻译”。

2021 年更新： 这是现在的包裹：

npm install react-localization

import ReactDOM from 'react-dom';
import React, { Component } from 'react';
import LocalizedStrings from 'react-localization';

let strings = new LocalizedStrings({
  en:{
    how:"How do you want your egg today?",
    boiledEgg:"Boiled egg",
    softBoiledEgg:"Soft-boiled egg",
    choice:"How to choose the egg"
  },
  it: {
    how:"Come vuoi il tuo uovo oggi?",
    boiledEgg:"Uovo sodo",
    softBoiledEgg:"Uovo alla coque",
    choice:"Come scegliere l'uovo"
  }
 });

class App extends Component {
  constructor(props) {
    super(props);
    this.state = {
      language: 'en'
    }
    
    this.handleLanguageChange = this.handleLanguageChange.bind(this);
  }

  handleLanguageChange(e) {
    e.preventDefault();
    let lang = e.target.value;
    this.setState(prevState => ({
      language: lang
    }))
  }

  render() {
    strings.setLanguage(this.state.language);
    return (
      <div>
        Change Language: <select onChange={this.handleLanguageChange}>
          <option value="en">En- English</option>
          <option value="it">It- Italian</option>
        </select>
        <br /><br />
        {strings.how}
      </div>
    )
  }
}

ReactDOM.render(<App />, document.getElementById('root'));

您可以将您的语言特定数据放入 JSON 文件或 .js 文件中。在当前文件中调用该文件并将该对象传递给 new LocalizedStrings().

示例： data.js

const data = {
  en:{
    how:"How do you want your egg today?",
    boiledEgg:"Boiled egg",
    softBoiledEgg:"Soft-boiled egg",
    choice:"How to choose the egg"
  },
  it: {
    how:"Come vuoi il tuo uovo oggi?",
    boiledEgg:"Uovo sodo",
    softBoiledEgg:"Uovo alla coque",
    choice:"Come scegliere l'uovo"
  }
}
export {data};

在您当前的文件中将其导入为 import { data } from './data.js'；然后你可以初始化为 let strings = new LocalizedStrings({data});

我们使用react-i18next。然后使用 i18nexus 自动翻译和管理翻译。
