const [name, setName] = useState("Jan");
  useEffect(() => 
    {document.title =   "Celebrate " +  {name}.name  ;}
  );
  

你可以使用下面的文档。title = '主页'

import React from 'react'
import { Component } from 'react-dom'


class App extends Component{
  componentDidMount(){
    document.title = "Home Page"
  }

  render(){
    return(
      <p> Title is now equal to Home Page </p>
    )
  }
}

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

或者你可以使用这个npm包npm i react-document-title

import React from 'react'
import { Component } from 'react-dom'
import DocumentTitle from 'react-document-title';


class App extends Component{


  render(){
    return(
      <DocumentTitle title='Home'>
        <h1>Home, sweet home.</h1>
      </DocumentTitle>
    )
  }
}

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

编码快乐! !

你可以简单地在js文件中创建一个函数，并将其导出到组件中使用

像下图:

export default function setTitle(title) {
  if (typeof title !== "string") {
     throw new Error("Title should be an string");
  }
  document.title = title;
}

并像这样在任何组件中使用它:

import React, { Component } from 'react';
import setTitle from './setTitle.js' // no need to js extension at the end

class App extends Component {
  componentDidMount() {
    setTitle("i am a new title");
  }

  render() {
    return (
      <div>
        see the title
      </div>
    );
  }
}

export default App

你可以创建TabTittleHelper.js和

export const TabTittle = (newTitle) => {
document.title=newTitle;
return document.title;
};

后来你编写了所有的屏幕

TabTittle('tittleName');

const [name, setName] = useState("Jan");
  useEffect(() => 
    {document.title =   "Celebrate " +  {name}.name  ;}
  );
  

对于这个问题，你有多种选择，我强烈建议使用React Helmet或使用useEffect创建钩子。除了编写自己的钩子，你还可以使用react-use中的钩子:

反应的头盔

import React from 'react';
import { Helmet } from 'react-helmet';

const MyComponent => () => (
  <Helmet>
    <title>My Title</title>
  </Helmet>
)

react-use

import React from 'react';
import { useTitle } from 'react-use';

const MyComponent = () => {
  useTitle('My Title');

  return null;
}
