@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

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);
}

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);

我刚刚花了一些认真的时间用React和滚动事件/位置来解决一些问题-所以对于那些仍然在寻找的人，这里是我发现的:

视口高度可以通过使用window来找到。innerHeight或使用document.documentElement.clientHeight。(当前视口高度)

整个文档(主体)的高度可以使用window.document.body.offsetHeight找到。

如果你试图找到文档的高度，并知道什么时候你已经触底了——下面是我想到的:

if (window.pageYOffset >= this.myRefII.current.clientHeight && Math.round((document.documentElement.scrollTop + window.innerHeight)) < document.documentElement.scrollHeight - 72) {
        this.setState({
            trueOrNot: true
        });
      } else {
        this.setState({
            trueOrNot: false
        });
      }
    }

(我的导航条在固定位置是72px，因此-72得到一个更好的滚动事件触发器)

最后，这里有一些到console.log()的滚动命令，这些命令帮助我积极地计算数学。

console.log('window inner height: ', window.innerHeight);

console.log('document Element client hieght: ', document.documentElement.clientHeight);

console.log('document Element scroll hieght: ', document.documentElement.scrollHeight);

console.log('document Element offset height: ', document.documentElement.offsetHeight);

console.log('document element scrolltop: ', document.documentElement.scrollTop);

console.log('window page Y Offset: ', window.pageYOffset);

console.log('window document body offsetheight: ', window.document.body.offsetHeight);

唷!希望它能帮助到一些人!

React原生web有一个useWindowDimensions钩子，可以使用:

    import { useWindowDimensions } from "react-native";
    const dimensions = useWindowDimensions()
