最巧妙的方法是:

    {React.cloneElement(this.props.children, this.props)}

这是你所要求的吗?

var Parent = React.createClass({
  doSomething: function(value) {
  }
  render: function() {
    return  <div>
              <Child doSome={this.doSomething} />
            </div>
  }
})

var Child = React.createClass({
  onClick:function() {
    this.props.doSome(value); // doSomething is undefined
  },  
  render: function() {
    return  <div onClick={this.onClick}></div>
  }
})

Parent.jsx:

import React from 'react';

const doSomething = value => {};

const Parent = props => (
  <div>
    {
      !props || !props.children 
        ? <div>Loading... (required at least one child)</div>
        : !props.children.length 
            ? <props.children.type {...props.children.props} doSomething={doSomething} {...props}>{props.children}</props.children.type>
            : props.children.map((child, key) => 
              React.cloneElement(child, {...props, key, doSomething}))
    }
  </div>
);

Child.jsx:

import React from 'react';

/* but better import doSomething right here,
   or use some flux store (for example redux library) */
export default ({ doSomething, value }) => (
  <div onClick={() => doSomething(value)}/>
);

和main.jsx:

import React from 'react';
import { render } from 'react-dom';
import Parent from './Parent';
import Child from './Child';

render(
  <Parent>
    <Child/>
    <Child value='1'/>
    <Child value='2'/>
  </Parent>,
  document.getElementById('...')
);

在我的情况下，React.cloneElement()给了我很多问题，我使用Typescript的函数组件，所以我用孩子(道具)作为一种方式来传递我的道具给我的孩子元素。同样，我的情况非常独特，我必须传递给父组件一个属性，然后基于该属性，它将某些道具传递给子组件。这可以在一个简单的CodeSandbox示例中看到

App.tsx

import "./styles.css";
import Parent from "./Parent";

export default function App() {
  return (
    <>
      <Parent title={"With div wrapper"}>
        {({ title }) => <h1>{title}</h1>}
      </Parent>

      <Parent>
        {({ title }) => <h1>{title === undefined && "this is undefined"}</h1>}
      </Parent>
    </>
  );
}

Parent.tsx

export interface ChildrenProps {
  title?: string;
}

interface ParentWrapperProps {
  children: (title: ChildrenProps) => JSX.Element;
  title?: string;
}

const ParentWrapper: React.FC<ParentWrapperProps> = ({ children, title }) => {
  return title ? (
    <div>{children({ title: title })}</div>
  ) : (
    <>{children({ title: undefined })}</>
  );
};

export default ParentWrapper;

允许你进行属性转移的最好方法是像函数模式一样的子元素 https://medium.com/merrickchristensen/function-as-child-components-5f3920a9ace9

代码片段:https://stackblitz.com/edit/react-fcmubc

例子:

const Parent = ({ children }) => {
    const somePropsHere = {
      style: {
        color: "red"
      }
      // any other props here...
    }
    return children(somePropsHere)
}

const ChildComponent = props => <h1 {...props}>Hello world!</h1>

const App = () => {
  return (
    <Parent>
      {props => (
        <ChildComponent {...props}>
          Bla-bla-bla
        </ChildComponent>
      )}
    </Parent>
  )
}

你不再需要{this.props.children}。现在你可以在Route中使用render来包装你的子组件，并像往常一样传递你的道具:

<BrowserRouter>
  <div>
    <ul>
      <li><Link to="/">Home</Link></li>
      <li><Link to="/posts">Posts</Link></li>
      <li><Link to="/about">About</Link></li>
    </ul>

    <hr/>

    <Route path="/" exact component={Home} />
    <Route path="/posts" render={() => (
      <Posts
        value1={1}
        value2={2}
        data={this.state.data}
      />
    )} />
    <Route path="/about" component={About} />
  </div>
</BrowserRouter>
