如何显示多个 YouTube 视频而不重叠音频

Question

我有一个包含一些 YouTube 视频嵌入代码的页面。当用户在一个视频上单击“>播放”时，页面上的所有其他视频都需要暂停，否则它们的音频会与刚刚播放的新视频重叠。

实现这一点最有效的方法是什么？

Answer 1

好吧，这是我根据其他人的一些代码提出的解决方案。

在您的 .js 文件中添加以下内容：

var videos = {};

$(document).ready(function(){
  // assigns ids to all the embed tags
  var i = 0;
  $('embed').each(function() {
    $(this).attr('id', "embed"+i);
    i++
  });
});

function onYouTubePlayerReady(playerId) {

  // loop through all embed tags assign a listener object only if not already assigned
  $('embed').each(function() {
    var embedid = $(this).attr('id');
    var ytplayer = document.getElementById(embedid);
    if (videos[embedid] == undefined) {
        window["dynamicYouTubeEventHandler" + embedid] = function(state) { onytplayerStateChange(state, embedid); }
        ytplayer.addEventListener("onStateChange", "dynamicYouTubeEventHandler"+embedid);
    }
    videos[embedid] = true;
  });
}

function onytplayerStateChange(newState, playerId) {
    // If one of the videos was played
    if (newState == 1) {
        // loop through each of the embed tags
        $('embed').each(function() {
            var embedid = $(this).attr('id');
            var ytplayer = document.getElementById(embedid);
            // Only pause video if not the current player
            if(embedid != playerId) {
                var current_state = ytplayer.getPlayerState();
                // Only pause if not already started
                if (current_state != '-1') {    ytplayer.pauseVideo();  }
            }
        });
    }
}

然后在您的 html 文件中，像这样嵌入您的 YouTube。确保 YouTube 文件的 URL 末尾有 enablejsapi=1：

<object width="500" height="400">
    <param name="movie" value="http://www.youtube.com/v/ms6GAdy6dag?version=3&enablejsapi=1">
    <param name="allowFullScreen" value="true">
    <param name="allowscriptaccess" value="always">
    <param name="wmode" value="transparent">
    <embed src="http://www.youtube.com/v/ms6GAdy6dag?version=3&enablejsapi=1" type="application/x-shockwave-flash" width="500" height="400" wmode="transparent" allowscriptaccess="always" allowfullscreen="true">
