javascript - YouTube iframe api 未捕获类型错误 : object is not a function?

Question

所以我使用以下方式加载 YouTube 播放列表:

event.target.loadPlaylist(videoIds);

我收到此错误:

奇怪的是播放列表加载良好大约一秒钟， 然后中断给我这个错误。

抱歉，这是周围的代码:

        window.tag = document.createElement('script');
        tag.src = "https://www.youtube.com/iframe_api";

        window.firstScriptTag = document.getElementsByTagName('script')[0];
        firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

        // 3. This function creates an <iframe> (and YouTube player)
        //    after the API code downloads.
        // window.player;
        window.onYouTubeIframeAPIReady = function() {
            player = new YT.Player('player', {
                height: '480',
                width: '853',
                playerVars: {
                    controls: 1,
                    modestbranding: 1,
                    playsinline: 1,
                    showinfo: 1,
                    iv_load_policy: 3,
                    rel: 0
                },
                events: {
                    'onReady': onPlayerReady,
                    'onStateChange': onPlayerStateChange
                }
            });
        }
        window.onPlayerReady = function(event) {
            //wierd 404 errors sometimes
            event.target.loadPlaylist(videoIds, 0, 0, 'large');
            event.target.playVideo();
        }

        window.onPlayerStateChange = function(event) {
            console.log('the state changed: '+ event.data);
            if (event.data === 1) {
                console.log(event.target.getDuration());
                globalYoutubePlayerCounter++;
                console.log('youtube player count: ' +globalYoutubePlayerCounter);
            }
            if (globalYoutubePlayerCounter >= 6) {
                /* load the next set of videos */
                globalYoutubePlayerCounter = 0;
                console.log('playlist ended');
                if (that.finalTrackList.length > 0) {
                    that.getNextTenMusic(event.target);
                }else{
                    // recall for general searches;
                    // that.getNextTenGeneral(event.target);
                }
                /* load the next set of videos */
            }
        }

即使出现错误，所有视频列表的格式也正确。 Console.log 证实了这一点。

我也遇到了同样的问题，但使用了 loadVideoById。对我来说，问题是播放器尚未完全初始化，因此实际上没有方法 loadVideoById。也许如果有人遇到同样的问题，请尝试推迟通话，看看是否有帮助。
