三分屏，这里的三分屏只是在一个播放器里同时播放三个视频，但是要求只有一个控制面板同时控制它们，要求它们共享一个时间轨道。这次只是简单的模拟了一下功能，并没有深入的研究。
首先，需要下载jPlayer，jPlayer是一个JavaScript写的完全免费和开源的jQuery多媒体库插件，我觉得他最大的好处就是兼容性，并且页面也简洁大方，个人比较喜欢。jPlayer可到其官网下载最新版本（http://www.jplayer.cn）。并且官网有开发文档和Demo，所以还是比较容易上手的。
关于简单的视频播放器和音频播放器这里不再赘述了，官网的Demo挺好的，这里直奔主题。
首先当然是引入jPlayer相关文件。
首先是css文件夹，这里为了方便，某些文件也放到css文件夹里了：
然后是js文件夹：
因为jPlayer是在jQuery的插件，所以jquery的包自然也就少不了了。
新建一个test.jsp页面，下面是代码：

新建一个test.js文件，下面是代码：
var flag = false;
var isFull = false;
$(document).ready(function() {
// 实例化第一个视频
$("#jquery_jplayer_1").jPlayer({
ready: function() {
$(this).jPlayer("setMedia", {
title: "This is video Title",
m4v: "http://www.jplayer.org/video/m4v/Big_Buck_Bunny_Trailer.m4v",
/* m4v: "video/003.webm", */
poster: "http://www.jplayer.org/video/poster/Big_Buck_Bunny_Trailer_480x270.png"
});
},
swfPath: "../../dist/jplayer",
supplied: "m4v",
size: {
width: "640px",
height: "360px",
cssClass: "jp-video-360p"
},
useStateClassSkin: true,
autoBlur: false,
smoothPlayBar: true,
keyEnabled: true,
remainingDuration: true,
toggleDuration: true
});
// 实例化第二个视频
$("#jquery_jplayer_2").jPlayer({
ready: function() {
$(this).jPlayer("setMedia", {
title: "This is video Title",
m4v: "http://www.jplayer.org/video/m4v/Big_Buck_Bunny_Trailer.m4v",
/* m4v: "video/003.webm", */
poster: "http://www.jplayer.org/video/poster/Big_Buck_Bunny_Trailer_480x270.png"
});
},
swfPath: "../../dist/jplayer",

cssClass: "jp-video-360p"
},
useStateClassSkin: true,

});
// 实例化第三个视频
$("#jquery_jplayer_3").jPlayer({
ready: function() {
$(this).jPlayer("setMedia", {
title: "This is video Title",
m4v: "http://www.jplayer.org/video/m4v/Big_Buck_Bunny_Trailer.m4v",
/* m4v: "video/003.webm", */
poster: "http://www.jplayer.org/video/poster/Big_Buck_Bunny_Trailer_480x270.png"
});
},
swfPath: "../../dist/jplayer",

cssClass: "jp-video-360p"
},
useStateClassSkin: true,
autoBlur: false,

});
// 绑定初始化事件，用于在页面加载的时候初始化控制条的位置
$("#jquery_jplayer_1").bind($.jPlayer.event.ready, function(event) {
$("#controller").css({
width: "959px",
margin: "0px 0px 0px -320px"
});
});
// 绑定页面大小变更事件，用于页面大小变化的时候，设置控制条的位置
$("#jquery_jplayer_1").bind($.jPlayer.event.resize, function(event) {
if (!isFull) {
$("#controller").css({
width: "100%",
margin: "0"
});
isFull = true;
} else {
$("#controller").css({
width: "959px",
margin: "0px 0px 0px -320px"
});
isFull = false;
}
});
// 绑定单击事件，用于单击屏幕控制视频的播放与暂停
$('#jquery_jplayer_1, #jquery_jplayer_2, #jquery_jplayer_3').bind("click", function(){
var $jplayer1 = $('#jquery_jplayer_1');
var $jplayer2 = $('#jquery_jplayer_2');
var $jplayer3 = $('#jquery_jplayer_3');
var status = $jplayer1.data("jPlayer").status;
if (status.paused) {
$jplayer1.jPlayer("play");
$jplayer2.jPlayer("play");
$jplayer3.jPlayer("play");
} else {
$jplayer1.jPlayer("pause");
$jplayer2.jPlayer("pause");
$jplayer3.jPlayer("pause");
}
});
});
// 双击屏幕时，进入全屏状态
function fullScreen() {
$("#jquery_jplayer_1").jPlayer("option", "fullScreen", true);
}
以上就是全部信息，需要注意的是，进入全屏状态的时候，只有主屏幕进入全屏，其它两个小的屏幕并不会进入全屏状态。
