如何在React應用中實(shí)現全屏功能

發(fā)布時(shí)間:2024-06-17 15:31:47 來(lái)源:億速云 閱讀:78 作者:小樊 欄目:web開(kāi)發(fā)

要在React應用中實(shí)現全屏功能,可以使用瀏覽器提供的Fullscreen API。以下是一種實(shí)現方式:

  1. 創(chuàng )建一個(gè)React組件FullPage,該組件包含一個(gè)按鈕,點(diǎn)擊按鈕可以切換全屏模式。
import React, { useState } from 'react';

const FullPage = () => {
  const [isFullscreen, setIsFullscreen] = useState(false);

  const toggleFullscreen = () => {
    if (!document.fullscreenElement) {
      document.documentElement.requestFullscreen();
      setIsFullscreen(true);
    } else {
      document.exitFullscreen();
      setIsFullscreen(false);
    }
  };

  return (
    <div>
      <button onClick={toggleFullscreen}>
        {isFullscreen ? 'Exit Fullscreen' : 'Fullscreen'}
      </button>
    </div>
  );
};

export default FullPage;
  1. 在根組件中引入FullPage組件。
import React from 'react';
import FullPage from './FullPage';

const App = () => {
  return (
    <div>
      <h1>React Fullscreen App</h1>
      <FullPage />
    </div>
  );
};

export default App;

通過(guò)以上步驟,你可以在React應用中實(shí)現全屏功能。當用戶(hù)點(diǎn)擊按鈕時(shí),頁(yè)面將切換到全屏模式,再次點(diǎn)擊按鈕將退出全屏模式。
