YouTube Player API - Playlist how to get the curre

问题:

I'm using YouTube Player API Reference for iframe the simple code

<div id="player"></div>
<script>
    //Load player api asynchronously.
    var tag = document.createElement('script');
    tag.src = "//www.youtube.com/iframe_api";
    var firstScriptTag = document.getElementsByTagName('script')[0];
    firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
    var done = false;
    var player;
    function onYouTubeIframeAPIReady() {
        player = new YT.Player('player', {
          height: '327',
          width: '530',
          videoId: '_XaWYzsY920',
          playerVars: { 'autoplay': 1,'playlist':['Hzgzim5m7oU', 'QvZIYIVNGZ0']},
          events: {
            'onReady': onPlayerReady,
            'onStateChange': onPlayerStateChange
          }
        });
    }
    function onPlayerReady(evt) {
        evt.target.playVideo();
    }
    function onPlayerStateChange(evt) {
        console.log(evt.data);
        console.log(evt.target.getVideoUrl());
    }
</script>

I thought to work out with evt.data == 5 but it's never fired so ......

Is there is way ?

回答1:

Inside onPlayerStateChange grab the video URL using evt.target.getVideoUrl() then extract the video id using regex:

function onPlayerStateChange(evt) {
    if (evt.data == YT.PlayerState.PLAYING) {
        var url = evt.target.getVideoUrl();
        // "http://www.youtube.com/watch?v=gzDS-Kfd5XQ&feature=..."
        var match = url.match(/[?&]v=([^&]+)/);
        // ["?v=gzDS-Kfd5XQ", "gzDS-Kfd5XQ"]
        var videoId = match[1];
    }
}

var videoId = evt.target.getVideoData().video_id
