我看了很多问题和youtube api的东西但是对于我的生活无法弄清楚为什么onYouTubeIframeAPIReady无法正常工作.

这是我的iframe:

<iframe id="youtube_vid" width="763" height="430" src="https://www.youtube.com/embed/dlJshzOv2cw?theme=light&amp;showinfo=0&amp;rel=0&amp;enablejsapi=1" frameborder="0" allowfullscreen=""></iframe>

我的剧本:

function callYTapi() {

    var tag = document.createElement('script');
    tag.src = "https://www.youtube.com/iframe_api";
    var firstScriptTag = document.getElementsByTagName('script')[0];
    firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
    console.log('script loaded');

    function onYouTubeIframeAPIReady() {
        console.log('IframeAPI = Ready');
        var player = new YT.Player('youtube_vid', {
            events: {
                'onReady': onPlayerReady,
                'onStateChange': onPlayerStateChange
            }
        });
    }

    function onPlayerReady(event) {
        event.target.playVideo();
    }

    function onPlayerStateChange(event) {
        if (event.data == YT.PlayerState.PAUSED) {
            console.log("Paused");
        }

        if (event.data == YT.PlayerState.PLAYING) {
            console.log("Playing");
        }

        if (event.data == YT.PlayerState.ENDED) {
            end(); 
        }
    } …
