基于jPlayer三分屏的制作方法

时间:2021-03-07 10:32:40 | 栏目:jquery | 点击:

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:

<!DOCTYPE html>
<html>
 <head>
  <meta charset="utf-8" />
  <title>JPlayer Test</title>
  <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
  <!-- 引入相关文件 -->
  <link href="css/jplayer.blue.monday.css" rel="stylesheet" type="text/css" />
  <script type="text/javascript" src="js/jquery.min.js"></script>
  <script type="text/javascript" src="css/jquery.jplayer.min.js"></script>
  <script type="text/javascript" src="js/jplayer.playlist.min.js"></script>
  <script type="text/javascript" src="test.js"></script>
 </head>
<body>
<div class="wrapper">

    <div ondblclick="fullScreen()" id="jquery_jplayer_2" class="jp-jplayer"></div>

         <div class="jp-volume-bar-value"></div>
        </div>
       </div>
       <div class="jp-toggles">

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",
  supplied: "m4v",
  size: {
   width: "320px",
   height: "180px",
   cssClass: "jp-video-360p"
  },
  useStateClassSkin: true,
  autoBlur: false,
  smoothPlayBar: true,
  keyEnabled: true,
  remainingDuration: true,
  toggleDuration: 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",
  supplied: "m4v",
  size: {
   width: "320px",
   height: "180px",
   cssClass: "jp-video-360p"
  },
  useStateClassSkin: true,
  autoBlur: false,
  smoothPlayBar: true,
  keyEnabled: true,
  remainingDuration: true,
  toggleDuration: true
 });

 // 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。
