使用react写一个滚动抽奖的代码

好的，以下是一个简单的React滚动抽奖组件的代码示例：

import React, { useState } from "react";
import axios from "axios";

const Lottery = () => {
  const [prizes, setPrizes] = useState([]);
  const [rolling, setRolling] = useState(false);
  const [result, setResult] = useState(null);

  const startRolling = () => {
    setRolling(true);
    // 假设抽奖后端接口返回的数据格式为：{id: 1, name: '奖品1'}
    axios.get("/api/lottery").then((response) => {
      setPrizes(response.data);
      const randomIndex = Math.floor(Math.random() * response.data.length);
      setResult(response.data[randomIndex]);
      setRolling(false);
    });
  };

  return (
    <div>
      <div className="lottery-container">
        {rolling ? (
          <div className="rolling">
            <div className="rolling-item">奖品1</div>
            <div className="rolling-item">奖品2</div>
            <div className="rolling-item">奖品3</div>
            <div className="rolling-item">奖品4</div>
            <div className="rolling-item">奖品5</div>
            <div className="rolling-item">奖品6</div>
            <div className="rolling-item">奖品7</div>
            <div className="rolling-item">奖品8</div>
            <div className="rolling-item">奖品9</div>
            <div className="rolling-item">奖品10</div>
          </div>
        ) : (
          <div className="lottery-result">{result ? result.name : ""}</div>
        )}
      </div>
      <button onClick={startRolling} disabled={rolling}>
        {rolling ? "抽奖中..." : "开始抽奖"}
      </button>
    </div>
  );
};

export default Lottery;

这个组件包含一个抽奖区域和一个抽奖按钮。当用户点击抽奖按钮时，组件会向后端发送请求以获取奖品数据，并开始滚动抽奖区域。当抽奖结束时，组件会显示抽奖结果。
