我刚刚编辑了QoP当前的答案以支持SSR，并将其与Next.js (React 16.8.0+)一起使用:

/钩/ useWindowDimensions.js:

import { useState, useEffect } from 'react';

export default function useWindowDimensions() {

  const hasWindow = typeof window !== 'undefined';

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

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

  useEffect(() => {
    if (hasWindow) {
      function handleResize() {
        setWindowDimensions(getWindowDimensions());
      }

      window.addEventListener('resize', handleResize);
      return () => window.removeEventListener('resize', handleResize);
    }
  }, [hasWindow]);

  return windowDimensions;
}

/ yourComponent.js:

import useWindowDimensions from './hooks/useWindowDimensions';

const Component = () => {
  const { height, width } = useWindowDimensions();
  /* you can also use default values or alias to use only one prop: */
  // const { height: windowHeight = 480 } useWindowDimensions();

  return (
    <div>
      width: {width} ~ height: {height}
    </div>
  );
}

我发现了一个简单的组合QoP和speckledcarp的答案，使用React Hooks和调整大小功能，代码行数略少:

const [width, setWidth]   = useState(window.innerWidth);
const [height, setHeight] = useState(window.innerHeight);
const updateDimensions = () => {
    setWidth(window.innerWidth);
    setHeight(window.innerHeight);
}
useEffect(() => {
    window.addEventListener("resize", updateDimensions);
    return () => window.removeEventListener("resize", updateDimensions);
}, []);

哦，是的，确保resize事件是双引号，而不是单引号。这一点让我有点不安;)

你也可以试试这个:

constructor(props) {
        super(props);
        this.state = {height: props.height, width:props.width};
      }

componentWillMount(){
          console.log("WINDOW : ",window);
          this.setState({height: window.innerHeight + 'px',width:window.innerWidth+'px'});
      }

render() {
        console.log("VIEW : ",this.state);
}

我建议使用useSyncExternalStore

import { useSyncExternalStore } from "react";

const store = {
  size: {
    height: undefined,
    width: undefined
  }
};

export default function ChatIndicator() {
  const { height, width } = useSyncExternalStore(subscribe, getSnapshot);
  return (
    <h1>
      {width} {height}
    </h1>
  );
}

function getSnapshot() {
  if (
    store.size.height !== window.innerHeight ||
    store.size.width !== window.innerWidth
  ) {
    store.size = { height: window.innerHeight, width: window.innerWidth };
  }
  return store.size;
}

function subscribe(callback) {
  window.addEventListener("resize", callback);
  return () => {
    window.removeEventListener("resize", callback);
  };
}

@speckledcarp和@Jamesl的回答都很精彩。然而，在我的例子中，我需要一个组件，其高度可以扩展整个窗口高度，在呈现时有条件....但是在render()中调用HOC会重新渲染整个子树。很糟糕。

另外，我对获取作为道具的值不感兴趣，但只是想要一个父div，将占据整个屏幕的高度(或宽度，或两者)。

所以我写了一个父组件，提供了一个完整的高度(和/或宽度)div。

一个用例:

class MyPage extends React.Component {
  render() {
    const { data, ...rest } = this.props

    return data ? (
      // My app uses templates which misbehave badly if you manually mess around with the container height, so leave the height alone here.
      <div>Yay! render a page with some data. </div>
    ) : (
      <FullArea vertical>
        // You're now in a full height div, so containers will vertically justify properly
        <GridContainer justify="center" alignItems="center" style={{ height: "inherit" }}>
          <GridItem xs={12} sm={6}>
            Page loading!
          </GridItem>
        </GridContainer>
      </FullArea>
    )

下面是这个组件:

import React, { Component } from 'react'
import PropTypes from 'prop-types'

class FullArea extends Component {
  constructor(props) {
    super(props)
    this.state = {
      width: 0,
      height: 0,
    }
    this.getStyles = this.getStyles.bind(this)
    this.updateWindowDimensions = this.updateWindowDimensions.bind(this)
  }

  componentDidMount() {
    this.updateWindowDimensions()
    window.addEventListener('resize', this.updateWindowDimensions)
  }

  componentWillUnmount() {
    window.removeEventListener('resize', this.updateWindowDimensions)
  }

  getStyles(vertical, horizontal) {
    const styles = {}
    if (vertical) {
      styles.height = `${this.state.height}px`
    }
    if (horizontal) {
      styles.width = `${this.state.width}px`
    }
    return styles
  }

  updateWindowDimensions() {
    this.setState({ width: window.innerWidth, height: window.innerHeight })
  }

  render() {
    const { vertical, horizontal } = this.props
    return (
      <div style={this.getStyles(vertical, horizontal)} >
        {this.props.children}
      </div>
    )
  }
}

FullArea.defaultProps = {
  horizontal: false,
  vertical: false,
}

FullArea.propTypes = {
  horizontal: PropTypes.bool,
  vertical: PropTypes.bool,
}

export default FullArea

在这里，您可以将投票次数最多的答案包装在一个节点包中(已测试，typescript)，以便使用。

安装:

npm i @teambit/toolbox.react.hooks.get-window-dimensions

用法:

import React from 'react';
import { useWindowDimensions } from '@teambit/toolbox.react.hooks.get-window-dimensions';

const MyComponent = () => {
  const { height, width } = useWindowDimensions();

  return (
    <>
      <h1>Window size</h1>
      <p>Height: {height}</p>
      <p>Width: {width}</p>
    </>
  );
};
