react 代码优化呈现
import React from ‘react‘
import ‘@/css1/UlList.scss‘
const arr = [[1, 2, 3, 4], [5, 6, 7, 8], [`#`, `%`, `(`, `)`]]
export default class Computers extends React.Component
constructor()
super()
this.state =
keyList = items =>
return items.map(item1 =>
return <span style= width: ‘200px‘, height:‘100px‘, borderRadius: ‘55px‘ ,float: ‘left‘,backgroundColor: ‘blueviolet‘,position: ‘relative‘,margin: ‘40px‘,textAlign: ‘center‘,lineHeight:‘100px‘, textShadow: ‘15 15 15 #f23a3a‘ >item1</span>
