React组件对子组件children进行加强的方法

React.cloneElement(element, [props], [...childrn])

<element.type {...element.props} {...props}>{children}</element.type>

// App.jsx
<Father>
 <div style={{ color: 'red' }} onClick={() => console.log('hello')}>
  demo
 </div>
<Father>

// Father.jsx
const Son = React.cloneElement(
 this.props.children,
 {
  style: {
   display: 'inline-block'
  }
 }
)

<div style={{ dispaly: 'inline-block' }}>
 <div style={{ color: 'red' }} onClick={() => console.log('hello')}>
  demo
 </div>
<div>

// this.props.children
console.log(
 <div
  style={{ color: 'red' }}
  onClick={() => {
   console.log('hello');
  }}
 >
  demo
 </div>
);

// Father.jsx
const { children } = this.props;
const Son = {
 ...children,
 props: {
   ...children.props,
  dispaly: {
   ...children.style,
   display: 'inline-block'
  },
  onTransitionEnd: () => { console.log('hello world') }
 }
}
