h5+js如何实现视频播放?本篇文章就给大家通过示例介绍使用h5+js制作视频播放器控件的方法,有一定的参考价值,有需要的朋友可以参考一下,希望对你有所帮助。【推荐教程:Html5视频教程】
由于h5兼容性问题,很多浏览器对于插入视频播放的支持都大不相同。火狐支持的比较完整,谷歌则支持的不是很好,很多功能都不能实现,这就需要我们去自制一个播放界面,去兼容不同的浏览器。
只插入一个视频时,浏览器中只会出现这样一个画面。只有单击右键才可以弹出菜单栏显示播放或者显示控件;
下面是一个自制播放控件的小练习,比较粗糙,很多功能有待完善。
制作中可能用到的一些常见属性和内容:
1、标签<video></video>
2、常用属性:
autoplay–自动播放;
controls–显示音乐控件;
loop–实现循环播放;
poster–视频加载未开始时播放的图片;
3、video支持多视频格式:(以此解决不同浏览器对视频格式的兼容问题)
<video poster="img/oceans-clip.png"> <source src="video/oceans-clip.mp4"></source> <source src="video/oceans-clip.webm"></source> <source src="video/oceans-clip.ogv"></source> </video>
4、获取当前视频播放的状态:
playbtn(对象).onclick=function(){ if(video.paused){ video.play(); }else{ video.pause(); } }
5、视频的一些特殊事件:
1)当视频可以播放获取总时间:
vdideo.oncanplay=function(){ console.log(video.duration); }
2)视频播放时,获取实时时间:
video.ontimedate=function(){ console.log(video.currentTime); }
3)视频结束:
video.onended=function(){ }
实现后的样式:
代码如下:
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>视频</title> <style type="text/css"> input,body,div{ margin: 0; padding: 0; } input{ display: inline-block; width: 30px; height: 30px; background-size: 30px; float: left; } #control{ width: 620px; height: 30px; background-color: #222; margin-top: -8px; padding: 5px 10px; clear: both; /*position: absolute; top:300px left: 100px;*/ } #jdt{ margin: 10px 5px 0 5px; width: 400px; height: 10px; float: left; } span { display: inline-block; color: #fff; float: left; margin: 6px 5px 0 5px; font: 14px "微软雅黑"; } #box1{ margin:50px auto; width: 615px; height: 305pc; /*position: relative;*/ } #playbnt{ } </style> </head> <body> <div id="box1"> <video poster="img/oceans-clip.png"> <source src="video/oceans-clip.mp4"></source> <source src="video/oceans-clip.webm"></source> <source src="video/oceans-clip.ogv"></source> </video> <div id="control"> <input type="image" value="" id="playbnt" src="img/on.png"/> <meter id="jdt" min="0" max="100"></meter> <span id="timeone">00:00:00</span> <span>/</span> <span id="timeall">00:00:00</span> <input type="image" value="" id="fullbnt" src="img/expand.jpg"/> </div> </div> <script type="text/javascript"> var playbnt=document.getElementById("playbnt"); var fullbnt=document.getElementById("fullbnt"); var video=document.querySelector("video"); var box1=document.getElementById("box1"); //播放按钮 playbnt.onclick=function(){ if(video.paused){ video.play(); playbnt.src="img/pause.png"; }else{ video.pause(); playbnt.src="img/on.png"; } } //点击进入全屏(注意兼容) fullbnt.onclick=function(){ if(document.fullscreenElement||document.webkitFullscreenElement||document.mozCancelFullScreen||document.msFullscreenElement){ if(document.cancelFullscreen){ document.cancelFullscreen(); }else if(document.webkitCancelFullscreen){ document.webkitCancelFullscreen(); }else if(document.mozCancelFullScreen){ document.mozCancelFullScreen(); }else if(document.msExitFullscreen){ document.msExitFullscreen(); } }else{ if(video.requestFullscreen){ video.requestFullscreen(); }else if(video.webkitRequestFullscreen){ video.webkitRequestFullscreen(); }else if(video.mozRequestFullScreen){ video.mozRequestFullScreen(); }else if(video.msRequestFullscreen){ video.msRequestFullscreen(); } } } //实时获取时间 var timh=0; var timm=0; var tims=0; var all=null; var one=null; var timeone=document.getElementById("timeone"); var jdt=document.getElementById("jdt"); video.ontimeupdate=function(){ var t=Math.floor(video.currentTime); ont=t; timh=t/3600; timm=t%3600/60; tims=t%60; // console.log(t); if(t<10){ timeone.innerHTML="00:00:0"+tims; }else if(10<t<60){ timeone.innerHTML="00:00:"+tims; }else if(60<t<600){ timeone.innerHTML="00:0"+timm+":"+tims; } else if(600<t<3600){ timeone.innerHTML="00:"+timm+":"+tims; }else if(3600<t<36000){ timeone.innerHTML="0"+timh+":"+timm+":"+tims; }else if(t>36000){ timeone.innerHTML=timh+":"+timm+":"+tims; } jdt.value=(t/all)*100; } //获取总时间 video.oncanplay=function(){ var t=Math.floor(video.duration); all=t timh=t/3600; timm=t%3600/60; tims=t%60; // console.log(t); if(t<10){ timeall.innerHTML="00:00:0"+tims; }else if(10<t<60){ timeall.innerHTML="00:00:"+tims; }else if(60<t<600){ timeall.innerHTML="00:0"+timm+":"+tims; } else if(600<t<3600){ timeall.innerHTML="00:"+timm+":"+tims; }else if(3600<t<36000){ timeall.innerHTML="0"+timh+":"+timm+":"+tims; }else if(t>36000){ timeall.innerHTML=timh+":"+timm+":"+tims; } } //视频结束时进度条 video.onended=function(){ playbnt.src="img/on.png"; timeone.innerHTML="00:00:00"; video.currentTime=0; } //单击进度条 var jdtl=jdt.offsetLeft; var jdtw=jdt.offsetWidth; jdt.onclick=function(event){ // console.log(all); var onex=Math.floor((event.clientX-jdtl));//点击坐标到进度条左端距离 console.log("鼠标单击坐标:"+event.clientX); // console.log(jdtl); var allx=Math.floor(jdtw); //进度条的宽度 var x=onex/allx; console.log("单击坐标-left="+onex); console.log("进度条宽度="+allx);//百分比 console.log("百分比="+x); video.currentTime=Math.floor(all*x); //实时时间=总时长*百分比 console.log("实时时间="+all*x); } </script> </body> </html>
