youtube video end

Question

我的页面中有多个youtube视频是基于日期DESC动态生成的。我想在视频结束后调用一个函数。我只想在一个视频中执行此操作（如最新的视频）。所有来自数据库的视频。 这是视频代码

<iframe width="560" height="315" id="player_video" src="https://www.youtube.com/embed/AEolY27i7yE?list=PLBFFEFD304803D5F5" frameborder="0" allowfullscreen></iframe>

我已为"player_video"

之类的iframe分配了ID

这是我的Js代码。

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;
    }
} 
     new YT.Player('player_video', {
            events: {
                'onStateChange': onPlayerStateChange
            }
        });

但它不起作用。有什么建议吗？
