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
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;
