关于javascript:将分钟转换成天小时分秒

将天/小时/分/秒一起转换

rom用于显示
iTime就是输出的分钟
TnT就是用于切换clearInterval()
本来我想用$off勾销ck事件，然而Vue3勾销了$off。真是惋惜

<div id="app">    <input type="text" v-model="iTime" @keyup.enter="ck" />    <button @click="rem">清空</button>    <p>        {{rom}}    </p></div>

export default {    data() {        return {            rom: "",            iTime: "",            TnT: true        }    },    methods: {        ck() {            let countTime = this.iTime * 60            this.TnT = true            this.iTime = ""            var sb = setInterval(() => {                let day = parseInt(countTime / 60 / 60 / 24)                let hr = parseInt(countTime / 60 / 60 % 24)                let min = parseInt(countTime / 60 % 60)                let sec = countTime % 60                sec = sec > 9 ? sec : '0' + sec                countTime--                this.rom = `${day}天${hr}小时${min}分${sec}秒`                if (this.TnT == false) {                    clearInterval(sb)                    this.iTime = ""                    this.rom = ""                }            }, 1000)        },        rem() {            this.TnT = false        }    }}
