通过在useCallback中包装getWindowDimensions函数，我对代码进行了轻微的更新

import { useCallback, useLayoutEffect, useState } from 'react';

export default function useWindowDimensions() {

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

    const getWindowDimensions = useCallback(() => {
        const windowWidth = hasWindow ? window.innerWidth : null;
        const windowHeight = hasWindow ? window.innerHeight : null;

        return {
            windowWidth,
            windowHeight,
        };
    }, [hasWindow]);

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

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

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

    return windowDimensions;
}

class AppComponent extends React.Component {

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

  componentWillMount(){
    this.setState({height: window.innerHeight + 'px'});
  }

  render() {
    // render your component...
  }
}

设置道具

AppComponent.propTypes = {
 height:React.PropTypes.string
};

AppComponent.defaultProps = {
 height:'500px'
};

视口高度现在可用{this.state。渲染模板中的Height}

这个答案与Jabran Saeed的类似，除了它也处理窗口大小的调整。接下来交给我吧。

constructor(props) {
  super(props);
  this.state = { width: 0, height: 0 };
  this.updateWindowDimensions = this.updateWindowDimensions.bind(this);
}

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

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

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

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;)

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

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

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

    return windowDimensions;
}
