在ReactJS试图实现谷歌翻译，并包括翻译组件在我的脚本文件.

谷歌翻译.js：

import React, { Component } from 'react';

class GoogleTranslate extends Component {
    googleTranslateElementInit () {
        //alert("test2")
        /* eslint-disable no-new */
        new window.google.translate.TranslateElement({pageLanguage: 'pt', layout: window.google.translate.TranslateElement.FloatPosition.TOP_LEFT}, 'google_translate_element')
     }

    componentDidMount() {
        // alert("test")

        var addScript = document.createElement('script');
        addScript.setAttribute('src', '//translate.google.com/translate_a/element.js?cb=googleTranslateElementInit');        
        document.body.appendChild(addScript);  
        window.googleTranslateElementInit = this.googleTranslateElementInit;
    }

    render() {
        return (
            // <script type='text/javascript' src='//translate.google.com/translate_a/element.js?cb=googleTranslateElementInit' />
            <div id="google_translate_element"></div>
          );
     }
}

export default GoogleTranslate;

管理员登录名.js：

import GoogleTranslate from '../Applicant/GoogleTranslate';

我使用<GoogleTranslate />来使用Adminlogin.js文件中包含的此组件。
并包括在我的文件的组成部分，当我登录到网站和注销后，当我导航到主页，有两个语言栏。

任何帮助都很感激。

在功能组件中尝试此操作，工作正常

const SamplePage = () => {

 const googleTranslateElementInit = () => {
   new window.google.translate.TranslateElement({ pageLanguage: 'en', layout: window.google.translate.TranslateElement.FloatPosition.TOP_LEFT }, 'google_translate_element')
  }
  
  useEffect(() => {
    var addScript = document.createElement('script');
    addScript.setAttribute('src', '//translate.google.com/translate_a/element.js?cb=googleTranslateElementInit');
    document.body.appendChild(addScript);
    window.googleTranslateElementInit = googleTranslateElementInit;
  }, [])

  return (
    <div>
      <h2 className="title gx-mb-4"><IntlMessages id="sidebar.samplePage"/></h2>
      <div id="google_translate_element"></div>
      <div className="gx-d-flex justify-content-center">
        <h4>Start building your app. Happy Coding!</h4>
      </div>

    </div>
  );
};

export default SamplePage

语言栏的重复或倍增是由于每次加载/呈现页面时调用document.body.appendChild(addScript)。
要解决此问题，请将插件初始化添加到public > index.html文件，如下所示：

<script src="https://translate.google.com/translate_a/element.js?cb=googleTranslateElementInit" async></script>
  <script type="text/javascript">
    function googleTranslateElementInit() {
      new google.translate.TranslateElement(
        {
          pageLanguage: "en",
          layout: window.google.translate.TranslateElement.InlineLayout.VERTICAL,
        }, 
        'google_translate_element'
      );
    }
  </script>

然后，将GoogleTranslate组件更改为

import React, { Component } from 'react';

class GoogleTranslate extends Component {
    render() {
        return (
            <div id="google_translate_element"></div>
          );
     }
}

export default GoogleTranslate;

如果这对你有用，请投赞成票。如果没用，请不要犹豫，留下评论。干杯！

因为在这个.googleTranslateElementInit上下文中找不到正确的。
您可以在构造函数中绑定函数：

constructor(props) {
    super(props);
    this.googleTranslateElementInit = this.googleTranslateElementInit.bind(this);
}

或在类中使用箭头函数bind

googleTranslateElementInit = () => {
   ...
}

对于Next.js

<Script src="//translate.google.com/translate_a/element.js?cb=googleTranslateElementInit" onLoad={() => {
        const googleTranslateElementInit = () => {
            new window.google.translate.TranslateElement({ pageLanguage: 'en'} , 'google_translate_element')
        }
        window.googleTranslateElementInit = googleTranslateElementInit;
}}/>
