经典回顾倒计时
倒计时的基本布局介绍。
一个内容区域和一个输入区域，内容区域进行划分
直接使用flex布局会更快一点。
js代码
我们利用一下模块化思想，直接把获得时间这个功能写成一个函数。方便后续的调用
function getTime() {const date = new Date()return `今年是${date.getFullYear()}年${date.getMonth()+1}月${date.getDate()}日`}document.querySelector('.contain-top').innerHTML = getTime()
然后将输入框中的事件给加载进去，注意格式的划分。使用基本的时间算法
const input = document.querySelector('input')function dateChat() {const nowdate = +new Date()let enddate = +new Date()let time = 0const date1 = new Date()enddate = +new Date(`${date1.getFullYear()}-${date1.getMonth()+1}-${date1.getDate()} ${input.value}`)time = (enddate - nowdate) / 1000let h = parseInt(time / 60 / 60 % 24)h = h < 10 ? '0 ' + h : h + " "let m = parseInt(time / 60 % 60)m = m < 10 ? '0 ' + m : m + " "let s = parseInt(time % 60)s = s < 10 ? '0' + s : sdocument.querySelector('.hour').innerHTML = hdocument.querySelector('.min').innerHTML = mdocument.querySelector('.second').innerHTML = s}
设置回车监听和按钮监听
input.addEventListener('keyup', function (e) {if (e.key === 'Enter') {if (input.value.length > 8) {alert('输入有误')} else {document.querySelector('.timeout').innerHTML = input.valuedateChat()setInterval(dateChat, 1000)}}})const button = document.querySelector('button')button.addEventListener('click', function () {if (input.value.length > 8) {alert('输入有误')} else {document.querySelector('.timeout').innerHTML = input.valuedateChat()setInterval(dateChat, 1000)}})
