react父传子(以及默认值)

子组件

import React, { Component } from "react";
import "./base.css"


// 父组件
export class TestHanderClick extends Component {
  //  static defaultProps是默认的写法，人家规定这样写的，你的默认值
  static defaultProps={
    bg:"pink",
    wi:"100px",
    he:"100px"
  }

  render() {
    return (
      // 使用值
      <div style={{  background: this.props.bg, width: this.props.wi,  height:this.props.he  }}>
        123
      </div>
    )
  }
}

export default TestHanderClick;

父组件

 {/* 父组件传递给子组件的值 */}
<TestHanderClick bg="blue"></TestHanderClick>
