有没有办法在变量更改（状态）上调用方法。如何获取哪些组件已更改的列表？

 componentDidUpdate(prevProps, prevState) {

    const {ID} = this.state
        if (this.ID !== this.previousID || this.cmbID !== this.previoudcmbID) {
            if(this.ID !== undefined && this.cmbID !== undefined)
            {
                this.reload3();

            //  console.log(this.prevProps)
                console.log(this.state.settings[0])
                console.log(this.prevState.settings[0])

            }



    }
    this.prevState = this.state;
}

如何简单地设置Material-UI Drawer的背景颜色？尝试了这个，但没有用

<Drawer 
  style={listStyle3}
  open={this.state.menuOpened}
  docked={false}
  onRequestChange={(menuOpened) => this.setState({menuOpened})}
/>

const listStyle3 = {
  background: '#fafa00',
  backgroundColor: 'red'
}
