我需要使用YouTube的API加载多个视频。这是我第一次使用它，所以我不确定我做错了什么，但这是我正在尝试的：
var player;
var player2;
function onYouTubePlayerAPIReady() {
player = new YT.Player('player', {
videoId: 'hdy78ehsjdi'
});
player2 = new YT.Player('player', {
videoId: '81hdjskilct'
});
}
由于 onYouTubeIframeAPIReady 函数只需要被调用一次，可以采用以下方法：
初始化并将视频播放器信息 (ControlId、width、height、VideoId) 保存在数组中
调用 onYouTubeIframeAPIReady 函数以创建所有视频播放器
var playerInfoList = [{id:'player',height:'390',width:'640',videoId:'M7lc1UVf-VE'},{id:'player1',height:'390',width:'640',videoId:'M7lc1UVf-VE'}];
function onYouTubeIframeAPIReady() {
if(typeof playerInfoList === 'undefined')
return;
for(var i = 0; i < playerInfoList.length;i++) {
var curplayer = createPlayer(playerInfoList[i]);
}
}
function createPlayer(playerInfo) {
return new YT.Player(playerInfo.id, {
height: playerInfo.height,
width: playerInfo.width,
videoId: playerInfo.videoId
});
}
<div id="ytplayer1"></div>
<div id="ytplayer2"></div>
<script>
var player;
var player2;
function onYouTubePlayerAPIReady() {
player = new YT.Player('ytplayer1', {
height: '390',
width: '640',
videoId: 'hdy78ehsjdi'
});
player2 = new YT.Player('ytplayer2', {
height: '390',
width: '640',
videoId: '81hdjskilct'
});
}
</script>
在Youtube API文档中描述了函数的参数：

The HTML
<div data-id="youtubevideoidhere" class="video"></div>
<div data-id="youtubevideoidhere" class="video"></div>
<div data-id="youtubevideoidhere" class="video"></div>
视频的JS脚本
// CREATE VIDEOS "CLASS" to handler videos
var Videos = (function() {
// VARIABLES
var $ = jQuery, // The jquery
players = [], // players array (to coltrol players individually)
queue = []; // videos queue (once api is ready, transform this into YT player)
// Constructor
function Videos() {}
// METHODS
// Add elements to queue
Videos.prototype.add = function($video) {
queue.push($video);
};
// Load YT API
Videos.prototype.loadApi = function() {
// jQuery get script
$.getScript("//www.youtube.com/iframe_api", function() {
// once loaded, create the onYouTubeIframeAPIReady function
window.onYouTubeIframeAPIReady = function() {
queue.forEach(function($video) {
// Create the YT player
var player = new YT.Player($video.get(0), {
'width': "100%",
'height': "100%",
'videoId': $video.data("id")
});
// add to players array
players.push(player);
});
};
});
};
return Videos;
})();
var videos = new Videos();
$('.video').each( function () {
videos.add( $(this) );
})
videos.loadApi();
player.playVideo()，但我不知道如何与上面的代码一起使用。当我运行此函数时，我得到了“未定义播放器”的错误提示。 - Eugene Chefranov<div id="js_youTubeContainer_{innov_mod_ytplayer:id}" class="embed-responsive embed-responsive-16by9">
<div id="js_youTubeFrame_{innov_mod_ytplayer:id}" class="embed-responsive-item"></div>
</div>这里说的"{innov_mod_ytplayer:id}"是我们CMS中的YouTube视频ID，它允许为每个嵌入项分配一个唯一的ID。稍后这非常重要。
在此之下，我会进行渲染：
var innovYouTube_{innov_mod_ytplayer:id} = new Ariba.Innovations.YouTube.Class({
'innovYouTubeVideoId': '{innov_mod_ytplayer:id}',
'innovYouTubeVideoTitle': '{innov_mod_ytplayer:title}',
'innovYouTubeDivId' : 'js_youTubeFrame_{innov_mod_ytplayer:id}'
});
innovYouTube_{innov_mod_ytplayer:id}.Init(); // And... Go!
var onYouTubeIframeAPIReady = (function() {
try{ //wrap this in try/catch because it actually throws errors when it runs subsequent times - this is expected as it's related to YouTube "rerunning" the function on other videos.
innovYouTube_{innov_mod_ytplayer:id}.config.functionCache = onYouTubeIframeAPIReady; //cache the existing global function
return function() {
try{
innovYouTube_{innov_mod_ytplayer:id}.onYouTubeIframeAPIReady(); //execute this instance's function
var newOnYouTubeIframeAPIReady = innovYouTube_{innov_mod_ytplayer:id}.config.functionCache.apply(this, arguments); //add instances to global function
return newOnYouTubeIframeAPIReady; //update global function
}catch(err){}
};
}catch(err){}
})();if (typeof Ariba === "undefined") { var Ariba = {}; }
if (typeof Ariba.Innovations === "undefined") { Ariba.Innovations = {}; }
if (typeof Ariba.Innovations.YouTube === "undefined") { Ariba.Innovations.YouTube = {}; }
if (typeof Ariba.Innovations.YouTube.Class === "undefined") {//this script may be embedded more than once - do this to avoid re-processing it on subsequent loads
Ariba.Innovations.YouTube.Class = function (config) {
this.static = {
'ytScriptId': 'js_youtubeFrameAPI',
'ytScriptUrl': 'https://www.youtube.com/iframe_api'
};//static configuration. Will overwrite any other settings with the same name
this.config = {//optional configuration variables. Will be overridden by instance or static settings with the same name.
'adobeAnalyticsFired': false
};
this.config = $.extend(true, this.config, config);//inserts (destructively!) the instance settings.
this.config = $.extend(true, this.config, this.static);//inserts (destructively!) the static settings.
this.config.this = this;
};
Ariba.Innovations.YouTube.Class.prototype.Init = function () {
//Note: have to allow it to write it over an over because calling the API script is what makes YouTube call onYouTubeIframeAPIReady.
//if (document.getElementById('js_youtubeFrameAPI') === null) { // don't add the script again if it already exists!
this.config.apiScript = document.createElement('script');
this.config.apiScript.src = 'https://www.youtube.com/iframe_api';
this.config.apiScript.id = 'js_youtubeFrameAPI' + this.config.innovYouTubeVideoId;
this.config.firstScriptTag = document.getElementsByTagName('script')[0];
this.config.firstScriptTag.parentNode.insertBefore(this.config.apiScript, this.config.firstScriptTag);
//}
//else { console.log("iframe script already embedded", this.config.innovYouTubeVideoId); }
}
Ariba.Innovations.YouTube.Class.prototype.onYouTubeIframeAPIReady = function (event) {
//console.log("onYouTubeIframeAPIReady", this.config.innovYouTubeVideoId, arguments);
var _this = this;
//console.log(this);
this.config.ytPlayer = new YT.Player(this.config.innovYouTubeDivId, {
videoId: this.config.innovYouTubeVideoId,
events: {
'onReady': _this.onPlayerReady.bind(_this),
'onStateChange': _this.onPlayerStateChange.bind(_this)
}
});
}
Ariba.Innovations.YouTube.Class.prototype.onPlayerReady = function (event) {
//console.log("onPlayerReady", this.config.innovYouTubeVideoId, event);
}
Ariba.Innovations.YouTube.Class.prototype.onPlayerStateChange = function (event) {
//console.log("onPlayerStateChange", this.config.innovYouTubeVideoId, event, this);
if (event.data === YT.PlayerState.PLAYING && !this.config.adobeAnalyticsFired) {
//console.log("YouTube Video is PLAYING!!", this.config.innovYouTubeVideoId);
this.config.adobeAnalyticsFired = true;
if (typeof _satellite !== "undefined") {
window._satellite.data.customVars.adhoc_tracker_val = "Innovations Video: " + this.config.innovYouTubeVideoTitle + " (" + this.config.innovYouTubeVideoId + ")";
_satellite.track('adhoctrack');
}
}
}
}另外需要注意的几点：
一旦解决了主要的全局回调问题，将作用域保留在类实例中就很容易。你只需要添加.bind()即可。例如：
'onReady': _this.onPlayerReady.bind(_this)
var _this = this;
这样做是为了避免意外丢失实例的“this”作用域。也许不是必需的，但这是我多年来采用的惯例。
总之，我已经花了一个星期的时间在这个问题上，并且认为我应该与SO社区分享它，因为从我的寻找答案中清楚地表明，很多人都在寻找解决方案。
我在React中需要相同的东西。在Vadim的答案基础上，您可以执行以下操作，并将它们添加到对象中，然后在不知道播放器数组外观的情况下创建播放器。
const YoutubeAPILoader = {
_queue: [],
_isLoaded: false,
load: function (component) {
// if the API is loaded just create the player
if (this._isLoaded) {
component._createPlayer()
} else {
this._queue.push(component)
// load the Youtube API if this was the first component added
if (this._queue.length === 1) {
this._loadAPI()
}
}
},
_loadAPI: function () {
// load the api however you like
loadAPI('//youtube.com/player_api')
window.onYouTubeIframeAPIReady = () => {
this._isLoaded = true
for (let i = this._queue.length; i--;) {
this._queue[i]._createPlayer()
}
this._queue = []
}
}
}
const iframes = [{id: 'hello'},...];
const inOnReadyScope = "I can be accessed by onPlayerReady"
function onYouTubeIframeAPIReady() {
for (let i = 0; i < iframes.length; i++) {
const player = new YT.Player(iframe.id, {
events {
onReady: onPlayerReady
}
}
function onPlayerReady(event){
event.target.setVolume(0);
console.log(inOnReadyScope)
// use anything on event
}
}
}
<iframe title="YouTube video player" src="https:YOUR CHANNEL Full Link" width="560" height="315" frameborder="0" allowfullscreen="allowfullscreen"></iframe>
我为了加载多个视频所做的是在视频之外单击时销毁iframe（您可以使用任何事件），然后再次创建div，以便您可以重用具有另一个视频ID的div。
<script type="text/javascript">
$(document).ready(function () {
$(".youtube-player").each(function () {
var playerid = $(this).attr("id");
setTimeout(function () {
onYouTubeIframeAPIReady2(playerid);
}, 2000);
});
});
function onYouTubeIframeAPIReady2(PlayerID) {
var ctrlq = document.getElementById(PlayerID);
console.log(ctrlq);
var player = new YT.Player(PlayerID, {
height: ctrlq.dataset.height,
width: ctrlq.dataset.width,
events: {
'onReady': function (e) {
e.target.cueVideoById({
videoId: ctrlq.dataset.video,
startSeconds: ctrlq.dataset.startseconds,
endSeconds: ctrlq.dataset.endseconds
});
}
}
});
}
</script>
function createPlayer(playerInfo) { return new YT.Player(playerInfo.id, { videoId: playerInfo.videoId, events: { 'onReady': onPlayerReady, 'onStateChange': onPlayerStateChange } }); } function onPlayerReady(event) { console.log('ready'); }- Fawn
