React-组件-高阶组件

高阶组件(Higher-Order Components，简称为 HOC)

• 参数为组件，返回值为新组件的函数就可以称之为高阶组件

import React from 'react';

class Home extends React.PureComponent {
    render() {
        return (
            <div>Home</div>
        )
    }
}

function enhanceComponent(WrappedComponent) {
    class AdvComponent extends React.PureComponent {
        render() {
            return (
                <div>
                    <WrappedComponent/>
                </div>
            )
        }
    }
    return AdvComponent;
}

const AdvComponent = enhanceComponent(Home);

class App extends React.PureComponent {
    render() {
        return (
            <div>
                <AdvComponent/>
            </div>
        )
    }
}

export default App;
