How can I pass a variable ID for the YouTube API

I am new to CS and currently working on personal projects. I am creating a web app where a user can copy and paste a YouTube URL to a video in a search box and then have the ability to watch the video on the same web page after clicking watch. To get the video ID, I have used a regex:
function getId(url) {
const regExp = /^.*(youtu.be\/|v\/|u\/\w\/|embed\/|watch\?v=|&v=)([^#&?]*).*/;
const match = url.match(regExp);
return (match && match[2].length === 11)
? match[2]
: null;
}
And this is how I am getting the user input:
var inputVal = document.getElementById("userInput").value;
To get the video ID, I am calling getId on the inputVal from the user:
var newVideoId = getId(inputVal)
Below is the YouTube API used to play a video on my page. However, I am finding it difficult to passing in the newVideoId variable to the API under the player object.
// 2. This code loads the IFrame Player API code asynchronously.
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
// 3. This function creates an <iframe> (and YouTube player)
// after the API code downloads.
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('player', {
height: '390',
width: '640',
videoId: 'newVideoId', //the problem lies here
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
// 4. The API will call this function when the video player is ready.
function onPlayerReady(event) {
event.target.playVideo();
}
// 5. The API calls this function when the player's state changes.
// The function indicates that when playing a video (state=1),
// the player should play for six seconds and then stop.
var done = false;
function onPlayerStateChange(event) {
if (event.data == YT.PlayerState.PLAYING && !done) {
setTimeout(stopVideo, 6000);
done = true;
}
}
function stopVideo() {
player.stopVideo();
}
}
The problem is that, nothing shows on my screen after clicking the button. I am able to console.log the ID; that means I am getting the correct ID from the regex equation.
I would appreciate any help on how to use a dynamic ID gotten from user in the API! Thanks

To play a video with the iframe api providing a video Id you can use this function:
loadVideoById({'videoId': 'bHQqvYy5KYo',
'startSeconds': 5,
'endSeconds': 60,
'suggestedQuality': 'large'});
From IFrame Player API:
This function loads and plays the specified video.
The required videoId parameter specifies the YouTube Video ID of the
video to be played. In the YouTube Data API, a video resource's id
property specifies the ID. The optional startSeconds parameter accepts
a float/integer. If it is specified, then the video will start from
the closest keyframe to the specified time. The optional endSeconds
parameter accepts a float/integer. If it is specified, then the video
will stop playing at the specified time.
This should do the trick.

Get all the video ID's from a YouTube playlist into a PHP array using YouTube API

I'm adding a custom player to my website and I have two issues.
My playlist on YouTube has 391 songs and the API player only loads 200.
I have problems shuffling the list using the API commands.
Here's the code that I'm using to call to the player:
<div class="videoplayer" id="ytplayer"></div>
<script>
var getRandom = function(min, max) {
return Math.random() * (max - min) + min;
};
// Load the IFrame Player API code asynchronously.
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/player_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
// Replace the 'ytplayer' element with an <iframe> and
// YouTube player after the API code downloads.
var player;
function onYouTubePlayerAPIReady() {
player = new YT.Player('ytplayer', {
height: '50',
width: '400',
events: {
'onReady': onPlayerReady
},
playerVars:{
list:'PLH30k6CwlcgK8C-LET6_ZrAWwYGLqT8R-',
index:parseInt(0),
suggestedQuality:'small',
controls:0,
autoplay:1
}
});
}
function onPlayerReady(event) {
event.target.setShuffle();
event.target.setLoop();
}
</script>
I tried to workaround the shuffle thing using:
function onPlayerReady(event) {
var num = parseInt(getRandom(1,391));
event.target.playVideoAt(num);
}
But it doesn't work like I want, so I want retrieve the ID's of all the videos in the playlist into an array, mix them and pass all the array to load each video. I was trying to use some examples from previous questions but those examples are not working anymore, if some of you guys has examples with the v3 of the YouTube API or actually working examples I will appreciate it.

First, you have to use iframe API
because, javascript API is outdated and deprecated
Look for youtube API documentation (list of deprecated api's on left side menu)
https://developers.google.com/youtube/iframe_api_reference?hl=fr
replacing
tag.src = "https://www.youtube.com/player_api";
// by
tag.src = "https://www.youtube.com/iframe_api";
and
function onYouTubePlayerAPIReady()
// by
function onYouTubeIframeAPIReady()
0 To fix shuffling, try to randomize at each end state
by using onPlayerStateChange event listener, and YT.PlayerState.ENDED
state.
1 You need to CUE the playlist to get whole video's ids
before the randomization.
and get them with proper method : getPlaylist()
var player;
var videoList, videoCount;
function onYouTubeIframeAPIReady()
{
player = new YT.Player('ytplayer',
{
height: '50',
width: '400',
events:
{
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
},
playerVars:
{
controls:0,
autoplay:0
}
});
}
function onPlayerReady(event)
{
// cue the playlist, to get the video's ids
event.target.cuePlaylist
({
listType: 'playlist',
list: 'PLH30k6CwlcgK8C-LET6_ZrAWwYGLqT8R-',
suggestedQuality:'small',
autoplay: 1,
index:0,
});
event.target.setLoop();
}
function onPlayerStateChange(event)
{
if(event.data == YT.PlayerState.CUED)
{
videoList = event.target.getPlaylist();
// to prevent adding new video and for the randomize
videoCount = videoList.length;
// get the ids before randomize playlist, send it
sendIds(videoList);
// starting the player (like autoplay)
event.target.playVideo();
}
// randomize at each video ending
if(event.data == YT.PlayerState.ENDED)
{
var num = getRandom(1,videoCount);
event.target.playVideoAt(num);
}
}
function sendIds(ids)
{
console.log(ids);
// make what you want to do with them... ajax call to your php
}

Black borders in YouTube player - Javascript API

I am adding a youtube video using YouTube Player API , based on the example provided from Getting Started.
Black borders(top and bottom) are my problem. And on YouTube Player Parameters I didn't find a parameter which can solve my problem.
Is there a way to hide the black borders, without CSS?
This is the code that I use(I only added playerVars in new YT.Player):
<!--1.The <iframe> (and video player)will replace this <div> tag.-->
<div id = "player"> < div>
<script>
// 2. This code loads the IFrame Player API code asynchronously.
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
// 3. This function creates an <iframe> (and YouTube player)
// after the API code downloads.
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('player', {
height : '390',
width : '640',
videoId : 'St_dIV8NIoc',
//
// here is where youtube player parameters are placed
//
playerVars : {
controls : 0,
cc_load_policy : 0,
loop : 1,
autoplay: 1,
modestbranding: 0,
rel: 0,
showinfo: 0
},
events : {
'onReady' : onPlayerReady,
'onStateChange' : onPlayerStateChange
}
});
}
// 4. The API will call this function when the video player is ready.
function onPlayerReady(event) {
event.target.playVideo();
}
// 5. The API calls this function when the player's state changes.
// The function indicates that when playing a video (state=1),
// the player should play for six seconds and then stop.
var done = false;
function onPlayerStateChange(event) {
if (event.data == YT.PlayerState.PLAYING && !done) {
setTimeout(stopVideo, 6000);
done = true;
}
}
function stopVideo() {
player.stopVideo();
}
</script>

The example adds 30px to the standard-height(for the controls).
When you don't show the controls use the standard-size(640x360)
The standard-sizes are listed at https://developers.google.com/youtube/iframe_api_reference#Playback_quality

Youtube iframe API does not work as expected

In one of my modals I want to display a youtube video. Which one (which ID) depends on which button is used to open the model.
<button class='yt-play' data-yt='xxxxxx'>Play video</button>
In my javascript file I'm using the YT player-api to generate an iframe; i followed the Getting started on google developers.
So In the modal I added an <div id='player'></div> and This is my included 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', {
videoId: '5ulO97zuVF0', //- just a temporary id
});
}
// on document ready do some jQuery things,
// like adding an event handler to the button.
$(document).ready(function (){
$('.yt-play').click(function(ev){
ev.preventDefault();
var videoid = $(this).data('yt');
player.loadVideoById(videoid);
$('#yt-player').modal('show');
player.playVideo();
});
});
The click-handler on yt-play should load the video by means of player.loadVideoById() as stated here in the documentation.
But somehow I get an javascript error: TypeError: player.loadVideoById is not a function
If I dump the player-object in the console I'm getting a nice player object; which holds amongst many others the loadVideoById function. At least it looks like it:
What's the reason the new video is not loaded?

It's possibly because the "loadVideoById" is not yet available.
You must construct your YT.Player Object with an events object, and include an "onReady" Event callback.
Then in your "onReady" callback function you bind your Button click event.
function onPlayerReady() {
$('.yt-play').click(function(ev){
ev.preventDefault();
var videoid = $(this).data('yt');
// player.loadVideoByID is now available as a function
player.loadVideoById(videoid);
$('#yt-player').modal('show');
player.playVideo();
});
}
player = new YT.Player('player', {
videoId: '5ulO97zuVF0', //- just a temporary id,
events:{
“onReady”: onPlayerReady
}
});
See the events section in the docs for more:
https://developers.google.com/youtube/iframe_api_reference#Events

add div element in html document
initial YT to global object in onYouTubeIframeAPIReady function
call YT object in your function

The code:
<script>
// load API
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
// define player
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('player', {
height: '360',
width: '640'
});
}
$(function () {
// load video and add event listeners
function loadVideo(id, start, end) {
// check if player is defined
if ((typeof player !== "undefined")) {
// listener for player state change
player.addEventListener('onStateChange', function (event) {
if (event.data == YT.PlayerState.ENDED) {
// do something
}
});
// listener if player is ready (including methods, like loadVideoById
player.addEventListener('onReady', function(event){
event.target.loadVideoById({
videoId: id,
startSeconds: start,
endSeconds: end
});
// pause player (my specific needs)
event.target.pauseVideo();
});
}
// if player is not defined, wait and try again
else {
setTimeout(loadVideo, 100, id, start, end);
}
}
// somewhere in the code
loadVideo('xxxxxxxx', 0, 3);
player.playVideo();
});
</script>

The other answers don't clarify the issue.
The YouTube api is confusing for sure! This is because the YT.Player constructer returns a dom reference to the iframe of the youtube player not to the YT player object.
In order to get a reference to the YT player we need to listen to the onReady event.
var ytPlayer;
var videoIframe = new YT.Player('player', {
videoId: 'xxxxxxx', // youtube video id
playerVars: {
'autoplay': 0,
'rel': 0,
'showinfo': 0
},
events: {
'onStateChange': onPlayerStateChange,
'onReady': function (ev) {
ytPlayer = ev.target;
}
}
});

Only 6 years late to the party, I have the solution.
The issue is that the YouTube API doesn't like the DOM shuffling Foundation does when it opens a modal.
The only way to achieve this is to create the YouTube player after opening the modal:
function play_video(ytid) {
modal = new Foundation.Reveal($('#yt_modal'),{});
modal.open();
ytplayer = new YT.Player('ytplayer', {
videoId: ytid,
height: '390',
width: '640',
playerVars: {
'playsinline': 1
},
events: {
'onReady': whatever()
}
});
}
This assumes
<div id="ytplayer"></div>
is inside your Foundation modal.
Oh and you'll need to remove the iframe each time else YouTube API just looks for the old iframe (which isn't where it expects, cos the modal is closed and the DOM has changed):
$(document).on('closed.zf.reveal', function(e) {
switch($(e.target).prop('id')) {
case 'yt_modal':
ytplayer.destroy();
break;
}
});
And regarding #Tosh's answer about the API returning a reference to the iframe not the player is not true as far as I can determine by comparing it to what's returned by onReady(ev.target) - they appear identical (so don't go down that blind alley like I did!)

Youtube Player API Samples

I was trying the following code from the samples given on developers.google.com/*
<script>
// 2. This code loads the IFrame Player API code asynchronously.
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
// 3. This function creates an <iframe> (and YouTube player)
// after the API code downloads.
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('player', {
height: '390',
width: '640',
videoId: 'yZxrao3zou4',
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
// 4. The API will call this function when the video player is ready.
function onPlayerReady(event) {
event.target.playVideo();
}
// 5. The API calls this function when the player's state changes.
// The function indicates that when playing a video (state=1),
// the player should play for six seconds and then stop.
var done = false;
function onPlayerStateChange(event) {
if (event.data == YT.PlayerState.PLAYING && !done) {
setTimeout(stopVideo, 6000);
done = true;
}
}
function stopVideo() {
player.stopVideo();
}
</script>
The code works perfectly when I have nothing else on my web page, but when I try to merge it with my project it doesn't seem to work.
I am guessing the problem is with the following lines:
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
Can someone tell me what does the above two lines do, especially the [0] part?
My code is pretty much the same except that instead of the script tag I have the code inside a function, which takes in a argument for the videoId.
EDIT:
My code is as follows:
<script>
// I have a input area, where the user can enter the movie name. When the user submits the movie name, I capture the val and pass it to the youtube().
function youtube(movie_name) {
var videoId;
$.ajax({
url:"https://www.googleapis.com/youtube/v3/search?part=snippet&q="+movie_name+"&type=video&key=my_key",
success: function (response) {
videoId = response.items[0].id.videoId;
findMovieById(videoId);
}
});
}
function findMovieById(videoID) {
$("#player").css('display', 'inline-block');
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
// 3. This function creates an <iframe> (and YouTube player)
// after the API code downloads.
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('player', {
height: '390',
width: '640',
videoId: ""+videoID,
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
// 4. The API will call this function when the video player is ready.
function onPlayerReady(event) {
alert('Player Ready');
event.target.playVideo();
}
// 5. The API calls this function when the player's state changes.
// The function indicates that when playing a video (state=1),
// the player should play for six seconds and then stop.
var done = false;
function onPlayerStateChange(event) {
if (event.data == YT.PlayerState.PLAYING && !done) {
setTimeout(stopVideo, 6000);
done = true;
}
}
function stopVideo() {
player.stopVideo();
}
}
</script>

The idea behind the sample code is that it is much more consistent when you load the YouTube iFrame library code after the rest of the page has loaded; hence the sample code demonstrates that you put an inline at the bottom of the page, and within that, you traverse the DOM, find a place where you can insert another tag, and do so dynamically (the [0] just says 'the first entry in the array of all elements of name in the document).
The logic here is that, when the iFrame library loads, it will call the function onYouTubeIframeAPIReady. But since the library loads asynchronously, it's best to load it this way to ensure that anything else that your API hooks might depend on (the element in the DOM you're binding to, for example) already exists.
Also note that, because the loaded library will always call the onYouTubeIframeAPIReady function, it MUST be defined outside any other function. Otherwise it isn't callable. That could be why nesting it inside your code somewhere isn't working.
Feel free to post some of your merged code for more detailed help.
