将分钟转换为天-小时-分钟-秒
把day/hour/minute/second转换成rom显示iTime是输入分钟TnT是切换clearInterval()本来想用$off取消ck事件，但是Vue3取消了$off。真可惜清除{{rom}}
exportdefault{data(){return{rom:"",iTime:"",TnT:true}},方法：{ck(){letcountTime=this.iTime*60this.TnT=truethis.iTime=""varsb=setInterval(()=>{letday=parseInt(countTime/60/60/24)lethr=parseInt(countTime/60/60%24)letmin=parseInt(countTime/60%60)letsec=countTime%60sec=sec>9?sec:'0'+seccountTime--this.rom=`${day}day${hr}hour${min}分钟${sec}秒`if(this.TnT==false){clearInterval(sb)this.iTime=""this.rom=""}},1000)},rem(){this.TnT=false}}}
