从我的构造函数对象创建一个youtube iframe视频，这样我就可以创建多个视频

creating a youtube iframe video from my constructor object so I can create multiple videos

本文关键字：视频 创建 就可以 iframe 一个 对象 构造函数 我的 youtube      更新时间：2023-09-26

我正在尝试使用youtube iframe api创建一个youtube视频以及我正在工作的构造函数，但我遇到了一个绊脚石。在我的Player函数中，我已经创建了一些默认属性，然后我将一些新属性传递到我的新对象中，以便通过扩展默认属性和新属性来创建一个播放器。我现在的问题是，我不确定我实际上如何初始化youtube视频?我不确定player = new YT.Player('player', {应该去哪里?

这是我正在制作的JS和jsFiddle http://jsfiddle.net/kyllle/6zuh5/7/

function Player(options) {  
  var $player = $(options.id);
  var defaults = {
    height: '100',
    width: '200',
    videoId: 'u1zgFlCw8Aw',
    events: {
      'onReady': onPlayerReady
    },
    playerVars: {
      modestbranding: 0,
      controls: 0, //remove controls
      showinfo: 0,
      enablejsapi : 1,
      iv_load_policy: 3
    }
  };
     
  var combinedOptions = _.extend(defaults, options);
  console.log('Combined Options', combinedOptions);
  return {    
    pause: function () {      
      $player.pauseVideo();    
    },
        
    seek: function () {       
      //$player.seekTo();          
    },
        
    destroy: function () {      
      $player.destroy();    
    },
        
    changeVideo: function () {      
      $player.stopVideo();    
    }  
  }
};
function onPlayerReady() {
  console.log('player fired');
}
var myPlayer = new Player({  
    id: '#divId',
    autoPlay: true,
    videoId: 'asdadads'
});

在changeVideo函数之后增加init函数。然后在实例化Player之后你会在那个新实例上调用init。(i.e. myPlayer.init())

下面是我在想的一个例子:我省略了下划线，而是使用了jQuery的$.extend函数，这样我就可以少添乱了:

<html>
<head>
    <title>Video Player</title>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
    <script>
        function Player(options) {  
        var defaults = {
            height: '100',
            width: '200',
            videoId: 'u1zgFlCw8Aw',
            events: { 'onReady': null},
            playerVars: {
                  modestbranding: 0,
                  controls: 0, //remove controls
                  showinfo: 0,
                  enablejsapi : 1,
                  iv_load_policy: 3
             }
          };
          var combinedOptions = $.extend(defaults, options);
          console.log('Combined Options', combinedOptions);
          return {
            player: null,
            pause: function () {      
                this.player.pauseVideo();    
            },
            seek: function () {       
              //this.player.seekTo();          
            },
            destroy: function () {      
                this.player.destroy();    
            },
            changeVideo: function () {      
                this.player.stopVideo();    
            },
            onPlayerReady: function() {
                this.player.play();
            },
            init: function() {
                this.player = new YT.Player(combinedOptions.id, {
                height: combinedOptions.height,
                width: combinedOptions.width,
                videoId: combinedOptions.videoId,
                events: {
                    'onReady': this.onPlayerReady,
                    'onStateChange': null
                }
                });
            }
             }
        };

        var myPlayer;
        function onYouTubeIframeAPIReady() {
            myPlayer = new Player({  
                id: 'divId',
                autoPlay: true,
                videoId: 'NeGe7lVrXb0'
            });
            myPlayer.init();
        }
        $(document).ready(function() {
            var tag = document.createElement('script');
            tag.src = "https://www.youtube.com/iframe_api";
            var firstScriptTag = document.getElementsByTagName('script')[0];
            firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);    
        });

    </script>
</head>
<body>
    <div id="divId"></div>
</body>
</html>

放置在你想要的视频位置:

<div width="200" height="100" onclick="loadVideo();"></div>

放置在页尾:

<script>
function loadVideo() { // 2. This code loads the IFrame Player API code asynchronously.
 var tag = document.createElement('script');
 tag.src = "http://www.youtube.com/player_api";
 var firstScriptTag = document.getElementsByTagName('script')[0];
 firstScriptTag.parentNode.insertBefore(tag, firstScriptTag); }
 // func loadVideo
 // 3. This function creates an <iframe> (and YouTube player)
 // after the API code downloads.
 var player;
 function onYouTubePlayerAPIReady() { player = new YT.Player('player', { height: '100', playerVars: { 'autoplay': 1, rel: 0 }, width: '200', videoId: 'mXtJ9BbeGB4', events: { 'onReady': onPlayerReady } }); }
 // 4. The API will call this function when the video player is ready.
 function onPlayerReady(event) { event.target.playVideo(); }
</script>

一个Player类的工作示例，用于创建和控制单独的播放器。

        this.pause = function(event){

        this.player = new YT.Player(this.options.id,this.options)
        //pause on click
        $(this.options.pauseID).bind('click',function(event){

  var myPlayer2 = new Player({

    pauseID:'#pause2',
    playID:'#play2',

    autoPlay: false,

创建Player类的代码是基于这个问题的
