YouTube(注入)视频结束回拨

Question

我将YouTube iframe注入文档中的div并将其绑定到click:

jQuery(document).ready(function($) {
    jQuery('.video-thumb').click(function(){
        ...
        $('#player').html('<iframe width="761" height="421" src="http://www.youtube.com/embed/' + $(this).attr('videoid') + '?rel=0&wmode=transparent" frameborder="0" allowfullscreen></iframe>');
        ...
    }
 }

我希望在视频结束时进行回调.我已经阅读了关于onYouTubePlayerAPIReady,但它必须放在文件准备就绪之外.

我试图通过这种结构加载视频播放器准备好文件:

var player;
function onYouTubePlayerAPIReady() {
    player = new YT.Player('player', {
      height: '421',
      width: '761',
      videoId: '',
      playerVars: { autoplay: 1, autohide: 1, showinfo: 0 },
      events: {
        'onReady': onPlayerReady,
        'onStateChange': onPlayerStateChange
      }
    });
}

但我遇到了一些问题:

• showinfo:0无法正常工作,最后还有其他视频缩略图
• 我不知道如何更改视频ID(并重新启动视频？)
• 比第一种方法更多的脚本错误(注入iframe)

我更喜欢使用第一种方法,但如何创建视频结束回调？谢谢.

以下代码的工作示例也在jsfiddle.net上.

一些说明:

• 使用iframe_api,而不是javascript_api
• YT.Player构造函数很小,因为您自己构建iframe.
• "playerVars"包含在iframe网址参数中.
• 设置参数"enablejsapi = 1".

<div id="container"></div>

JavaScript

function log(msg) {
    jQuery('#log').prepend(msg + '<br/>');
}

function onPlayerStateChange(event) {
    switch(event.data) {
        case YT.PlayerState.ENDED:
            log('Video has ended.');
            break;
        case YT.PlayerState.PLAYING:
            log('Video is playing.');
            break;
        case YT.PlayerState.PAUSED:
            log('Video is paused.');
            break;
        case YT.PlayerState.BUFFERING:
            log('Video is buffering.');
            break;
        case YT.PlayerState.CUED:
            log('Video is cued.');
            break;
        default:
            log('Unrecognized state.');
            break;
    }
}

jQuery(document).ready(function($) {
    $('.video-thumb').click(function() {

        var vidId = $(this).attr('id');
        $('#container').html('<iframe id="player_'+vidId+
            '" width="420" height="315" src="http://www.youtube.com/embed/'+
            vidId+'?enablejsapi=1&autoplay=1&autohide=1&showinfo=0" '+
            'frameborder="0" allowfullscreen></iframe>');

        new YT.Player('player_'+vidId, {
            events: {
                'onStateChange': onPlayerStateChange
            }
        });
    });
});
