@foad abdollahi和@giovannipds答案的组合帮助我在Nextjs中使用useLayoutEffect自定义挂钩找到了一个解决方案。

function getWindowDimensions() {
    const { innerWidth: width, innerHeight: height } = window;
    return {
      width,
      height,
    };
  }

  function useWindowDimensions() {
    const [windowDimensions, setWindowDimensions] = useState(
      getWindowDimensions()
    );

    useLayoutEffect(() => {
      const isWindow = typeof window !== 'undefined';
      function handleResize() {
        setWindowDimensions(getWindowDimensions());
      }

      isWindow && window.addEventListener('resize', handleResize);
      console.log(windowDimensions);
      return () =>
        isWindow && window.removeEventListener('resize', handleResize);
    }, [windowDimensions]);

    return windowDimensions;
  }

作为回答从:bren，但挂钩useEffect到[window.innerWidth]

const [dimension, updateDimention] = useState();
  
  useEffect(() => {
    window.addEventListener("resize", () => {
        updateDimention({ 
            ...dimension, 
            width: window.innerWidth, 
            height: window.innerHeight 
        });
       
    })
},[window.innerWidth]);

 console.log(dimension);

添加这个是为了多样性和干净的方法。

此代码使用函数式方法。我已经使用onresize而不是addEventListener，如在其他答案中提到的。

import { useState, useEffect } from "react";

export default function App() {
  const [size, setSize] = useState({
    x: window.innerWidth,
    y: window.innerHeight
  });
  const updateSize = () =>
    setSize({
      x: window.innerWidth,
      y: window.innerHeight
    });
  useEffect(() => (window.onresize = updateSize), []);
  return (
    <>
      <p>width is : {size.x}</p>
      <p>height is : {size.y}</p>
    </>
  );
}

这是你如何实现它，并在React函数组件中实时获得窗口宽度和高度:

import React, {useState, useEffect} from 'react' 
const Component = () => {
  const [windowWidth, setWindowWidth] = useState(0)
  const [windowHeight, setWindowHeight] = useState(0)
  
  useEffect(() => {
    window.addEventListener('resize', e => {
      setWindowWidth(window.innerWidth);
    });
  }, [window.innerWidth]);

  useEffect(() => {
    window.addEventListener('resize', e => {
      setWindowHeight(window.innerHeight);
    });
  }, [window.innerHeight]);

  return(
    <h3>Window width is: {windowWidth} and Height: {windowHeight}</h3>
  )
}

保持当前尺寸状态的简单方法，即使在窗口调整大小后:

//set up defaults on page mount
componentDidMount() {
  this.state = { width: 0, height: 0 };
  this.getDimensions(); 

  //add dimensions listener for window resizing
  window.addEventListener('resize', this.getDimensions); 
}

//remove listener on page exit
componentWillUnmount() {
  window.removeEventListener('resize', this.getDimensions); 
}

//actually set the state to the window dimensions
getDimensions = () => {
  this.setState({ width: window.innerWidth, height: window.innerHeight });
  console.log(this.state);
}

使用useEffect很简单

useEffect(() => {
    window.addEventListener("resize", () => {
        updateDimention({ 
            ...dimension, 
            width: window.innerWidth, 
            height: window.innerHeight 
        });
        console.log(dimension);
    })
})
