}
.box {
width: 600px;
margin: 50px auto;
display: flex;
font-size: 25px;
line-height: 40px;
}
.qs {
width: 450px;
height: 40px;
color: red;
}
.btns {
text-align: center;
}
.btns button {
width: 120px;
height: 35px;
margin: 0 50px;
}
.selected {
width: 600px;
margin: 50px auto;
display: flex;

<body>
<h2>随机抽奖</h2>
<div class="box">
<span>当前奖品：</span>
<div class="qs">点击开始抽奖</div>
</div>
<div class="btns">
<button class="start">开始</button>
<button class="end">结束</button>
</div>
<div class="selected">

<div class="list"></div>
</div>
<script>
// 奖品池
const prizes = [
'iPhone 15 Pro',
'Switch 游戏机',
'小米平板 6',
'100 元话费',
'蓝牙耳机',
'腾讯视频年卡',
'机械键盘',
'充电宝',
'抱枕',
'谢谢参与',
'再来一次'
];
let timerId = 0;
let random = 0;
const qs = document.querySelector('.qs');
const listBox = document.querySelector('.list');
const start = document.querySelector('.start');
const end = document.querySelector('.end');
start.addEventListener('click', () => {
if (prizes.length <= 1) {
start.disabled = end.disabled = true;
return;
}
timerId = setInterval(() => {
random = Math.floor(Math.random() * prizes.length);
qs.textContent = prizes[random];
}, 100);
});
end.addEventListener('click', () => {
clearInterval(timerId);
const prize = prizes.splice(random, 1)[0];
showPrize(prize);
});
function showPrize(prize) {
const div = document.createElement('div');
div.textContent = prize;
listBox.appendChild(div);
}
</script>
</body>
</html>2、运行结果
可以连续抽奖十次
