要放假了，利用js写个下班倒计时

function getEndTime() {
     let s = Math.ceil((new Date(new Date().toLocaleDateString()+'/18:00').getTime() - new Date().getTime())/1000)
     let timer = setInterval(()=>{
         s--
         if(s>0) {
             console.log(`距离下班还剩${s}秒`)
         }else {
             clearInterval(timer)
             console.log(`下班啦!`)
         }

     },1000)
 }
 getEndTime()
