YT 未定义 - 未捕获的 ReferenceError：[youtube api]

删除了不需要的代码演示

嘿， 我正在实现 Youtube Video Player Api，我在控制台中看到某种错误。

视频如何完美播放，但我想知道为什么会出现错误？如果我将代码保留在骨架模式之外，就不会出现任何错误。

有人可以解释一下吗..

Thanks!!

JS :

(function($) {
    $(function(){
        var cVid, ytData1;
        var callFlexSlider = ({         
            embedVideos : function(){
                function explodeSlider(){
                    $('.sliderNew .flexslider').flexslider({
                        slideshow: false
                    });
                    $('.sliderNew #carousel, .sliderNew .flex-direction-nav').hide();
                }
                function explodeShow(){
                    $('.sliderNew .flexslider').flexslider({ 
                        slideshow: true
                    });
    $('.sliderNew #carousel, .sliderNew .flex-direction-nav').show();
                }
                function getArtistId() {
                    return window.artist_id;
                }
                function loadPlayer() {

                        var tag = document.createElement('script');
                        tag.src = "https://www.youtube.com/iframe_api";
                        var firstScriptTag = document.getElementsByTagName('script')[0];
                        firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
                        window.onYouTubePlayerAPIReady = function() {
                            onYouTubePlayer();

                    }
                }
                var player;

                function onYouTubePlayer() {

                        events: {

                }
                var done = false;

                function onPlayerStateChange(event) {
                    if (event.data == YT.PlayerState.PLAYING && !done) {
                        done = true;
                    } else if (event.data == YT.PlayerState.ENDED) {
                        location.reload();
                        event.target.destroy();
                    }

                    //alert('asdsad');
                    //player.destroy();
                    player.stopVideo();
                    explodeShow();
                }

            },
            init : function(){
                this.embedVideos();
            }

    }); 
    callFlexSlider.init();
    });
})(jQuery);

调用这个loadPlayer();在 document.ready 函数中尝试一下。

  function loadScript() {
                        if (typeof(YT) == 'undefined' || typeof(YT.Player) == 'undefined') {
                            var tag = document.createElement('script');
                            tag.src = "https://www.youtube.com/iframe_api";
                            var firstScriptTag = document.getElementsByTagName('script')[0];
                            firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
                        }
                    }

                    function loadPlayer() {
                            window.onYouTubePlayerAPIReady = function() {
                                onYouTubePlayer();
                            };
                    }


$(function () {
  loadScript();
})
