YT 未定义 - 未捕获的 ReferenceError:[youtube api] [英] YT is not defined - Uncaught ReferenceError: [youtube api]

问题描述

删除不需要的代码演示

嘿，我正在实施 Youtube Video Player Api，但在控制台中看到某种错误.

Hey, I am implementing Youtube Video Player Api and i see some sort of error in console.

视频如何完美播放，但我想知道错误是什么?如果我将代码保留在骨架模式之外，就不会有任何错误.

any how the video plays perfectly, but i want to know why the error is? if i keep the code outside of Skeleton Patterns, there wont be any error.

有人可以遮一些光吗..

can someone please shade some light..

谢谢！！

推荐答案

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

Call this loadPlayer(); inside document.ready function and try.

  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();
})
