在 youtube javascript api 中禁用自动播放

Question

我知道如何使用自动播放：参数和 url 中均为 0。问题是当我使用 loadVideoByID() 函数时。最初的视频似乎总是不自动启动。但当我加载新视频时，新视频就会自动启动。我也不希望新的自动启动

$(document).ready(function() {
var player;
window.onYouTubePlayerAPIReady = function() {
    player = new YT.Player('player', {
        height : '390',
        width : '640',
        videoId : 'JW5meKfy3fY',
        playerVars : {
            'autoplay' : 0,
            'rel' : 0,
            'showinfo' : 0,
            'egm' : 0,
            'showsearch' : 0,
            'controls' : 0,
            'modestbranding' : 1,
        },
        events : {
            'onReady' : onPlayerReady,
            'onStateChange' : onPlayerStateChange
        }
    });

};

window.onPlayerReady = function(event) {
    //event.target.playVideo();
    loadNewVid("bHQqvYy5KYo");
};

window.onPlayerStateChange = function(event, element) {
    //When the video has ended
    if (event.data == YT.PlayerState.ENDED) {
        //Get rid of the player
        element.style.display = "none";
    }
};

function loadNewVid(vidID){
    player.loadVideoById(vidID, "large");

}

});

Answer 1

根据定义， loadVideoById() 加载并播放视频。你想用的是 cueVideoById(), ，这将准备好它，但等待命令实际播放。

Answer 2

我认为这篇文章已经很老了，但无论如何我都会分享我的方法，以防有人偶然发现它，就像我刚才所做的那样：

由于没有办法调用 loadVideoById 并防止自动播放，我建议致电 destroy() 方法并使用新的 ID 重新实例化它。

让我们说这样的话：

$(document).ready(function() {
var player;
var playerParams = {
    height : '390',
    width : '640',
    videoId : 'JW5meKfy3fY',
    playerVars : {
        'autoplay' : 0,
        'rel' : 0,
        'showinfo' : 0,
        'egm' : 0,
        'showsearch' : 0,
        'controls' : 0,
        'modestbranding' : 1,
    },
    events : {
        'onReady' : onPlayerReady,
        'onStateChange' : onPlayerStateChange
    }
}

window.onYouTubePlayerAPIReady = function() {
    player = new YT.Player('player', playerParams);

};

window.onPlayerReady = function(event) {
    //event.target.playVideo();
    loadNewVid("bHQqvYy5KYo");
};

window.onPlayerStateChange = function(event, element) {
    //When the video has ended
    if (event.data == YT.PlayerState.ENDED) {
        //Get rid of the player
        element.style.display = "none";
    }
};

function loadNewVid(vidID){
    player.destroy();
    playerParams.videoId = vidID;
    player = new YT.Player('player', playerParams);

}
});

我希望这会有所帮助
