获取 youtube 播放列表索引 [英] get youtube playlist index

问题描述

我使用 youtube API(使用 javascript)在我的网站中嵌入了一个播放列表，并且该播放列表包含 3 首歌曲.

I have a playlist embeded in my website using the youtube API (with javascript) and the playlist has 3 songs.

问题:如何获取当前正在播放的歌曲的索引?

QUESTION: How can I get the index of the song that is currently playing?

详细说明我的意思:

在以下代码片段中:

function onYouTubePlayerAPIReady() {
    player = new YT.Player('player', {
        height: '390',
        width: '640',
        loadPlaylist:{
            listType:'playlist',
            list:['1asdfasdfs','2asdfasdfs','3asdfasdfs'],
            index:parseInt(0),
            suggestedQuality:'small'
        },
        events: {
            'onReady': onPlayerReady,
            'onStateChange': onPlayerStateChange
        }
    });
}

index:parseInt(0) 告诉 youtube api 从列表中的第一首歌曲 (1asdfasdfs) 开始播放歌曲.我假设该索引在不断变化，因为用户可以单击播放列表中的 3 首歌曲中的任何一首并随时切换到另一首歌曲.我想知道有什么方法可以获取当前索引.

index:parseInt(0) is telling the youtube api to start playing the song from the first song in the list (1asdfasdfs). I am assuming that this index is contantly shifting, since the users can click any of the 3 songs in the playlist and shift to another song at any time they want. What I would like is to know what method exists to get the current index.

注意:我意识到我可能有点笨拙，使用 player.getVideoData()['video_id']; 来检索视频 ID，然后循环通过三首歌曲的列表 ['1asdfasdfs','2asdfasdfs','3asdfasdfs'] 然后将该视频 ID 的位置保存在数组中，但是我相信有一种更清晰的方法可用，可能youtube api中的方法?不过我好像在任何地方都找不到.

Note: I recognize that I could be a bit hacky and use player.getVideoData()['video_id']; to retrieve the video id, and then loop through the list of three songs ['1asdfasdfs','2asdfasdfs','3asdfasdfs'] and then save the position of that video id in the array, however I believe there is a cleaner method available, possibly a method in the youtube api? I can't seem to find it anywhere though.

推荐答案

您可能只想使用 player.getPlaylistIndex()
