如何在reactjs中实现本地化？

Question

我们需要在reactjs中实现本地化来定义字符串值.我该如何实现呢？

一个链接是https://www.npmjs.com/package/react-localization,但我没有得到添加它的步骤.

我试过以下步骤: -

1. 我在ES6中添加我的组件: -

   class Home扩展了React.Component {constructor(props){super(props);

   }
   
   render() {
       return (
         <Text>{strings.how}
        </Text>
   
   );
   }
   

   }

2. 我已将本地化代码添加为: -

从'react-localization'导入LocalizedStrings;

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"
    }
});

现在,如果您将看到上述内容: - {strings.how}我应该能够获得字符串值,因为它在本地化中定义但我无法做到.

雅虎已经创建了一个用于在React中实现本地化的软件包,可能正是您所需要的: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".

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。在当前文件中调用该文件，然后将该对象传递给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};

在当前文件中将其导入为import { data } from './data.js'; 然后您可以初始化为let strings = new LocalizedStrings({data});
