javascript - 刷新YouTube Javascript直到页面刷新

Question

我有一个来自Javascript片段的youtube视频。该功能允许选择章节onClick-允许用户在不同时间播放视频(startSeconds)-在刷新页面或随机刷新之前，视频不会加载。第一次加载页面时，没有骰子。控制台中什么都没有显示，我已经在Chrome和Safari中对它进行了测试，结果相同。

我的代码:

<div id="player"></div>

<script type="text/javascript">
var tag = document.createElement('script');

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

var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('player', {
  width: '800',
  videoId: 'YQY9BZBrZds',
  events: {
    'onStateChange': onPlayerStateChange    
  },
  playerVars:{
    rel: 0,
    wmode: "opaque"
  }         
});
}

function onPlayerStateChange(evt) {
if (evt.data == 0) {
      $('#video_popup').removeClass('hide_pop');
      $('#video_popup').addClass('display_pop');
}
else if (evt.data == -1) {
      $('#video_popup').removeClass('display_pop');
      $('#video_popup').addClass('hide_pop');
}
else {
      $('#video_popup').removeClass('display_pop');
      $('#video_popup').addClass('hide_pop');
 }
 }

function chapter1() {
//player.loadVideoById({'videoId': 'YQY9BZBrZds', 'startSeconds': 0});
  player.cueVideoById('YQY9BZBrZds', 0);
  player.playVideo();
}

function chapter2() {
//player.loadVideoById({'videoId': 'YQY9BZBrZds', 'startSeconds': 22});
player.cueVideoById('YQY9BZBrZds', 22);
player.playVideo();
}

function chapter3() {
//player.loadVideoById({'videoId': 'YQY9BZBrZds', 'startSeconds': 44});
player.cueVideoById('YQY9BZBrZds', 44);
player.playVideo();
}

function chapter4() {
//player.loadVideoById({'videoId': 'YQY9BZBrZds', 'startSeconds': 87});
player.cueVideoById('YQY9BZBrZds', 87);
player.playVideo();
}

function chapter5() {
 //player.loadVideoById({'videoId': 'YQY9BZBrZds', 'startSeconds': 149});
player.cueVideoById('YQY9BZBrZds', 149);
player.playVideo();
}

如您所见，视频位于1 2 3指示下。

YouTube API loadVideoById startSeconds not working

谢谢任何能提供真知灼见的人!

我认为您不应该使用cueVideoById。此功能将视频添加到播放器的提示。但这是同一视频。

This function loads the specified video's thumbnail and prepares the player to play the video.

您应该使用seekTo函数，它将使您的视频正确位置而无需重新加载视频。

Seeks to a specified time in the video. If the player is paused when the function is called, it will remain paused. If the function is called from another state (playing, video cued, etc.), the player will play the video.

文档:https://developers.google.com/youtube/js_api_reference?hl=en#seekTo

您的函数应如下所示:

function chapter1() {
    player.seekTo(0);
}
