html自定义video播放器
seo靠我 2023-09-25 23:13:36本章的css可以说约等于没有，全是逻辑，仅供参考
html
<!DOCTYPE html> <html lang="en"> <head><meta charset="UTSEO靠我F-8"><meta http-equiv="X-UA-Compatible" content="IE=edge"><meta name="viewport" content="width=devicSEO靠我e-width, initial-scale=1.0"><title>视频</title><link rel="stylesheet" href="index.css" /> </heSEO靠我ad> <body><div><video src="你的视频名称&路径.mp4" id="myVideo" onclick="player()"></video><div classSEO靠我="timeStyle"></div></div> </body> <script src="index.js"></script> </html>首先SEO靠我你要获取到video元素
//全局变量 const myVideo = document.getElementById("myVideo")//video,获取到的是元素标签信息播放&暂SEO靠我停
这是一个点击事件,函数名为player
const player = () => {if(myVideo.paused){myVideo.play() //播放}else {myVideo.pauseSEO靠我() //暂停} }时间格式化函数
这是一个函数,函数名为JiSuanHMS
const JiSuanHMS = (time) => {if(time >= 60 * 60 *60){ /SEO靠我/ 大于一小时//h:m:sh = time / 60 / 60^0 //^0:四舍五入整数化m = time / 60 % 60^0s = time % 60 % 60^0return h + : SEO靠我+ m + : + s}else { //小于一小时//m:sm = time / 60 % 60^0s = time % 60 % 60^0return m + : + s} }即将SEO靠我播放事件函数(oncanplay)
本章只是配置时间和进度条，所以之后有的功能自行添加
//全局变量 //播放的时间元素标签获取,是个class const timeStySEO靠我le = document.querySelector(".timeStyle")//time 获取视频总时间 video.duration //是一个浮点类型 SEO靠我 获取视频当前时间 video.currentTime//是一个浮点类型 myVideo.oncanplay = () => {const allTiSEO靠我me = JiSuanHMS(myVideo.duration)const cTime = JiSuanHMS(myVideo.currentTime)timeStyle.innerHTML = `<SEO靠我div>${cTime}/${allTime}</div>` //写入元素 }暂停后将即将播放事件函数(onplaying)
我们这里先不做任何处理(你可以不写)
myVideo.onplSEO靠我aying = () => {//就是暂停后要播放时会调用// console.log(test)// console.log(myVideo.duration) }播放时事件函数(oSEO靠我nplay )
这个事件是在我们播放视频时调用。我们这里只是定义了一个定时器，每一秒去读取当前视频时间(currentTime)的值，至于总时间(duration)因为是innerHTML 重写，所以也SEO靠我要加上去
//定时器定义与初始值 let inter = null //全局变量 myVideo.onplay = () => {inter = setIntervalSEO靠我(()=>{const allTime = JiSuanHMS(myVideo.duration)const cTime = JiSuanHMS(myVideo.currentTime)timeStySEO靠我le.innerHTML = `<div>${cTime}/${allTime}</div>`},1000) }暂定时事件函数(onpause )
这个事件是在我们暂停视频时调用。这里我SEO靠我们的逻辑是暂停时我们取消定时器(停止获取)
myVideo.onpause = () => {console.log(pause)clearInterval(inter)inter = null SEO靠我 }视频时间更新事件函数(ontimeupdate)
这个事件在我们视频播放的时候就会被调用，停止视频后就不会调用
进度条显示 <div class="proessBox"><diSEO靠我v id="proess"></div> </div> //需要获取到的元素(全局常量) const proess = document.getEleSEO靠我mentById(proess) //进度条元素duration和currentTime的定义
myVideo.ontimeupdate = () => {// console.log(durationSEO靠我:,myVideo.duration)// console.log(currentTime:,myVideo.currentTime)//console.log(myVideo.currentTimeSEO靠我/myVideo.duration)//0.00*****************,所以需要乘100proess.style.width = myVideo.currentTime/myVideo.dSEO靠我uration*100 + % } .proessBox{ /*进度条全貌*/position: absolute;left: 0;top: 520pSEO靠我x;width: 300px;height: 15px;background-color: red;display: flex;z-index: -1;/*最底*/ } SEO靠我 #proess{position: absolute;left: 0;top: 0;height: 100%;background-color: skyblue;z-index: 5;/*比proeSEO靠我ssBox高一些的*/ } 进度条拖拽 //proessBox是进度条的父级 //onmousedown: 鼠标点击事件 SEO靠我 proessBox.onmousedown = (event)=>{// console.log(event:,event.pageX) //关键// console.log(proess.cliSEO靠我entWidth,proess.clientWidth)// console.log(proess.clientHeight:,proess.clientHeight)// console.log(pSEO靠我roessBox.offsetWidth:,proessBox.offsetWidth)// console.log(proessBox.offsetHeight:,proessBox.offsetHSEO靠我eight)// console.log(proessBox:,proessBox.offsetLeft) //0let len = event.pageX - proessBox.offsetLefSEO靠我tlet percent = len / proessBox.offsetWidth;// console.log(percent)proess.style.width = percent * (prSEO靠我oessBox.offsetWidth) - 2 + "px";myVideo.currentTime = percent * myVideo.duration; }追加: 键盘事件
oSEO靠我nkeydown: 键盘被按下onkeyup: 松开键盘的按键重点是keyCode
使用的事件是window.onkeyup()
键盘空格键的ascii码event.keyCode显示是32
if(evenSEO靠我t.keyCode === 32){//空格按下//播放暂停逻辑if(myVideo.paused){myVideo.play()}else {myVideo.pause()} } SEO靠我 键盘左箭头的ascii码event.keyCode显示是37
逻辑是时间不能小于0和点击键盘的左箭头回退5秒
if(event.keyCode === 37){//左箭头:37let cTSEO靠我ime = JiSuanHMS(myVideo.currentTime)if(myVideo.currentTime < 0){//if(cTime < 0:5){//cTime小于5秒(myVideSEO靠我o.currentTime或者不能小于0)console.log(cTime)return}const returnTime = JiSuanHMS(myVideo.currentTime - 5)cSEO靠我onsole.log(左箭头:,cTime,returnTime:,returnTime)myVideo.currentTime = myVideo.currentTime - 5cTime = JiSEO靠我SuanHMS(myVideo.currentTime) } 键盘右箭头的ascii码event.keyCode显示是39
逻辑是时间不能大于视频的最大时间和点击键盘的SEO靠我右箭头前进5秒
if(event.keyCode === 39){//右键头:39let cTime = JiSuanHMS(myVideo.currentTime)let allTime = JiSuSEO靠我anHMS(myVideo.duration)if(myVideo.currentTime > myVideo.duration){//大于最大值console.log(cTime:,cTime,alSEO靠我lTime:,allTime)return}const addTime = JiSuanHMS(myVideo.currentTime + 5)console.log(右箭头:,myVideo.curSEO靠我rentTime,addTime:,addTime)myVideo.currentTime = myVideo.currentTime + 5cTime = JiSuanHMS(myVideo.curSEO靠我rentTime) }完整代码
