手写antd按钮组件

通过模仿antd按钮组件的实现，可以扩展自己自定义组件的能力。

1. 分析按钮组件

Button组件有几大属性：

• type: default,primary,link
• danger: 布尔值
• size: small, middle, large
• icon: 图标

2. 编写按钮组件

创建文件夹JKAntd，并在里面创建JKButton文件夹，分别在JKButton文件夹下面创建JKButton.jsx,JKButton.css, 然后再JKAntd创建index.js

JKButton.jsx

import classNames from 'classnames'
import './JKButton.css'
import PropTypes from 'prop-types'
function JKButton({type, danger, size, icon}) {
  const btnStyle =classNames({
    'jk-ant-btn': true,
    'jk-ant-btn-danger': danger,
    [`jk-ant-btn-${type}`]: true,
    [`jk-ant-btn-${size}`]: true,
  })

  return (
    <button className={btnStyle}>{icon && <span>{icon}</span>}按钮</button>
  )
}

JKButton.defaultProps = {
  type: 'default',
  danger: false,
  size: 'middle',
  icon: null
}
// 限制传值的类型
JKButton.propTypes = {
  type: PropTypes.string,
  danger: PropTypes.bool,
  size: PropTypes.oneOf(['small', 'middle', 'large']),
  icon: PropTypes.element,
}

export default JKButton;

JKButton.css

.jk-ant-btn{
    font-size: 14px;
    line-height: 1.5714285714285714;
    height: 32px;
    padding: 4px 15px;
    border-radius: 6px;
    outline: none;
    position: relative;
    display: inline-flex;
    gap: 8px;
    align-items: center;
    justify-content: center;
    font-weight: 400;
    white-space: nowrap;
    text-align: center;
    background-image: none;
    background: transparent;
    border: 1px solid transparent;
    cursor: pointer;
    transition: all 0.2s cubic-bezier(0.645, 0.045, 0.355, 1);
    user-select: none;
    touch-action: manipulation;
    color: rgba(0, 0, 0, 0.88);
}

.jk-ant-btn-default{
    border-color: #d9d9d9;
    background: #ffffff;
    color: rgba(0, 0, 0, 0.88);
    box-shadow: 0 2px 0 rgba(0, 0, 0, 0.02);
}

.jk-ant-btn-primary{
    color: #fff;
    background: #1677ff;
    box-shadow: 0 2px 0 rgba(5, 145, 255, 0.1);
}
.jk-ant-btn-danger{
    color: #fff;
    background: #ff4d4f;
}
.jk-ant-btn-large{
    font-size: 16px;
    line-height: 1.5;
    height: 40px;
    padding: 7px 15px;
    border-radius: 8px;
}

.jk-ant-btn-small{
    font-size: 14px;
    line-height: 1.5714285714285714;
    height: 24px;
    padding: 0px 7px;
    border-radius: 4px;
}

App17.jsx

import { Button, Row, Space } from 'antd'
import { PlusCircleFilled } from '@ant-design/icons'
import { JKButton } from './JKAntd'

function App() {
  return (
    <>
      <Row>
        <Space>
          <Button type="default" >按钮</Button>
          <Button type="primary" >按钮</Button>
          <Button type="primary" danger>按钮</Button>
          <Button type="primary" size='small'>按钮</Button>
          <Button type="primary" size='large'>按钮</Button>
          <Button type="primary" icon={<PlusCircleFilled/>}>按钮</Button>
        </Space>
      </Row>
      <br/>
      <br/>
      <Row>
        <Space>
          <JKButton type="default" >按钮</JKButton>
          <JKButton type="primary" >按钮</JKButton>
          <JKButton type="primary" danger>按钮</JKButton>
          <JKButton type="primary" size='small'>按钮</JKButton>
          <JKButton type="primary" size='large'>按钮</JKButton>
          <JKButton type="primary" icon={<PlusCircleFilled/>}>按钮</JKButton>
        </Space>
      </Row>
    </>
  )
}
export default App

index.js

import JKButton from './JKButton/JKButton.jsx'

export  {JKButton}

执行效果：
