react 5分钟写一个乐透开奖

 import { useState } from 'react'; const Lottery = () => { const [pool,setPool]=useState([]) // 设置奖池初始值 // 生成一个随机数字 const randomNumber = (min, max) =>{ const range = max - min + 1; const rand = Math.random() ; const num = Math.floor(rand * range + min); return num; } // 奖池生成器 const generator = (n，min，max)=>{ const arr = []; while(arr.length<n){ const num = randomNumber(min,max) if (arr.indexOf(num)===-1){ arr.push(num) } } return arr; } return ( <div> <button onClick={()=>setPool(generator(6，1,45))}>一键开奖</button> <button onClick={()=>setPool([])}>清空奖池</button> <div className="lottery"> <ul> {pool.map((num,i)=>(<li key={i}><div>{num}</div></li>))} </ul> </div> </div> ); }; export default Lottery;
