很多小伙伴们都有在网页中进行观看视频的习惯,那么大家知道这是怎么进行播放的吗?那么今天我们就来说说:“HTML5中视频播放(video)和JavaScript控制视频效果怎么实现?”这个问题吧!
具体代码如下所示:
<html> <head> <meta charset="UTF-8"> <title>Documenttitle> <style> figcaption { text-align: center; line-height: 150px; font-family: "Microsoft Yahei"; font-size: 24px; } .player { width: 720px; height: 360px; margin: 10px auto; border: 1px solid #000; background-color: #000; position: relative; border-radius: 6px; } .player video { width: 720px; height: 360px; } .controls { width: 700px; height: 40px; background-color: rgba(255,255,0,0.3); position: absolute; bottom: 10px; left: 10px; border-radius: 10px; } .switch { position: absolute; width: 22px; height: 22px; background-color: red; left: 10px; top: 9px; border-radius: 50%; } .progress { width: 432px; height: 10px; position: absolute; background-color: rgba(255,255,255,0.4); left: 40px; top: 15px; border-radius: 4px; overflow: hidden; } .curr-progress { width: 0%; height: 100%; background-color: #fff; } .time { width: 120px; height: 20px; text-align: center; line-height: 20px; font-size: 12px; color: #fff; position: absolute; left: 510px; top: 10px; } .extend { position: absolute; width: 20px; height: 20px; background-color: red; right: 10px; top: 10px; } style> head> <body> <figure> <figcaption>视频案例figcaption> <div> <video src="11.mp4">video> <div> <a href="#">a> <div> <div>div> div> <div> <span>00:00:00span>/ <span>00:00:00span> div> <a href="#">a> div> div> figure> <script> var video = document.querySelector('video'); var playBtn = document.querySelector('.switch'); var currProgress = document.querySelector('.curr-progress'); var currTime = document.querySelector('.curr-time'); var totalTime = document.querySelector('.total-time'); var extend = document.querySelector('.extend'); var tTime = 0; playBtn.onclick = function() { if(video.paused){ // 如果视频是暂停的 video.play(); //play()播放 load()重新加载 pause()暂停 }else{ video.pause(); } } //当视频能播放(已经通过网络加载完成)时 video.oncanplay = function() { tTime = video.duration; //获取视频总时长(单位秒) var tTimeStr = getTimeStr(tTime); totalTime.innerHTML = tTimeStr; } //当视频当前播放时间更新的时候 video.ontimeupdate = function() { var cTime = video.currentTime; //获取当前播放时间 var cTimeStr = getTimeStr(cTime); console.log(cTimeStr); currTime.innerHTML = cTimeStr; currProgress.style.width = cTime/tTime*100+"%"; } extend.onclick = function() { video.webkitRequestFullScreen(); //视频全屏 } //将以秒为单位的时间变成“00:00:00”格式的字符串 function getTimeStr(time) { var h = Math.floor(time/3600); var m = Math.floor(time%3600/60); var s = Math.floor(time%60); h = h>=10?h:"0"+h; m = m>=10?m:"0"+m; s = s>=10?s:"0"+s; return h+":"+m+":"+s; } script> body> html>
