这是一个很简约的时钟。。。。。。。

效果：

代码： 

<template><div class="demo-box"><div class="clock"><ul class="mark"><liv-for="(rotate, index) in rotatedAngles":key="index":class="{ 'bold': index % 5 === 0 }":style="{ transform: `translateY(90px) rotate(${rotate}deg)` }"></li></ul><div id="min"></div><div id="hour"></div><div id="sec"></div></div></div>
</template><script setup>
import {onMounted, computed} from 'vue';let timer = nullconst rotatedAngles = computed(() => {return Array.from({length: 60}, (_, index) => index * 6);
})const startTime = () => {const min = document.getElementById('min')const sec = document.getElementById('sec')const hour = document.getElementById('hour')const now = new Date()const s = now.getSeconds()const then = new Date(now.getFullYear(), now.getMonth(), now.getDate(), 0, 0, 0)const diffInMil = now.getTime() - then.getTime()const h = diffInMil / (1000 * 60 * 60)const m = h * 60;if (hour || min || sec) {hour.style.transform = `rotate(${h * 30}deg)`;min.style.transform = `rotate(${m * 6}deg)`;sec.style.transform = `rotate(${s * 6}deg)`;}
}onMounted(() => {startTime()timer = setInterval(() => {setTimeout(startTime, 0)}, 1000)
})</script><style scoped lang="scss">
