Question about JavaScript scope and is it possible to accomplish what I am attempting to do

I am attempting to dynamically change the videoID of the YouTube API onclick. I have a list of items whose data src contains a YouTube URL. When a user clicks on a link, a modal pops up's playing that particular video. Once the video finishes, it redirects to another page.
If I hard code the ID, it works beautifully, but I cannot do that.
My only concern is I cannot get the videoID due to JavaScript scope. Is there anything you'd recommend I try?
$(document.body).on('click', ".video-btn", function (e) {
var $videoSrc = $(this).data("src");
console.log($videoSrc);
var **getVidID** = $videoSrc.substring(26);
console.log(getVidID);
});
var tag = document.createElement('script');
tag.src = "//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', {
playerVars: {
'controls': 0
},
width: 1920,
height: 1080,
videoId: **getVidID,** I'd like to use the videoID here
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
};
function onPlayerReady(event) {
event.target.playVideo();
};
var done = false;
function onPlayerStateChange(event) {
if (event.data == YT.PlayerState.ENDED && !done) {
alert('Taking you to Review Material Now..')
window.location.replace("http://www.google.com");
done = true;
}
};

Here's one way to do it:
var getVidID;
$(document.body).on('click', ".video-btn", function (e) {
var $videoSrc = $(this).data("src");
console.log($videoSrc);
getVidID = $videoSrc.substring(26);
console.log(getVidID);
});
var tag = document.createElement('script');
tag.src = "//www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
var player;
function onYouTubeIframeAPIReady() {
console.log(getVidID);
player = new YT.Player('player', {
playerVars: {
'controls': 0
},
width: 1920,
height: 1080,
videoId: **getVidID,** I'd like to use the videoID here
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
};
Be aware: getVidID may not have a value, depending on where/when you call onYouTubeIframeAPIReady(). The click event function must run before it gets the id. So, you may want to validate that it has a value before you use it in that other function. Also, be aware that the value of that variable only changes when the click event fires...

In Youtube player, see the frame when it's paused

I'm doing an application that uses youtube API. I select the time with the "seekto" function, but when the video jumps to that time, it appears like the following screenshot:
There's any option to remove all this things (bar, load circle, ...), and only see the frame of the video in that time??
Code:
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', {
playerVars: { 'autoplay': 0, 'controls': 2 },
height: '390',
width: '640',
videoId: '1WcvD6lu2Yg',
events: {
'onReady': onPlayerReady,
}
});
}
function onPlayerReady(event) {
event.target.pauseVideo();
}
function salta(sec) {
player.seekTo(sec, true);
}
Thank you!
Edited:
Solved, the problem was the parameter "false" of the function seekTo. In "true" position, it loads the following second correctly.

Play between certain time onclick button - youtube iframe api

I have one Youtube video which has 6 episodes and I have six buttons which onclick will skip to the start of that particular episode.
Here is the working fiddle for that.
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', {
height: '360',
width: '640',
videoId: 'L6cVcbkx8l8',
events: {
'onReady': onPlayerReady,
}
});
}
function onPlayerReady(event) {
event.target.playVideo();
$('#episode1').click(function(evt){
console.log($(evt.currentTarget).val());
player.seekTo(50)
})
$('#episode2').click(function(evt){
console.log($(evt.currentTarget).val());
player.seekTo(100)
})
$('#episode3').click(function(evt){
console.log($(evt.currentTarget).val());
player.seekTo(150)
})
}
What I am actually trying to do is when someone is clicking on episode2, it should play between only that time code (say xx.yy to aa.bb). So, how do I mention the end time for each episode onclick.

Insert YouTube iframe after the page is loaded

I have a main YouTube video and some related videos at the bottom. YouTube video is loaded from a costum video name parameter in my url. If a video name exists YouTube iframe is loaded on page load but if a video name dosen't exists YT iframe isn't loaded until the user clicks a related video at the bottom. If the user clicks an related video the iframe is loaded and the same function onPlayerReady, and onPlayerStateChange should be used as the iframe was loaded from the begining. How can I insert the iframe in page and use the same function I use as it was loaded from the beginning. ?
player.js
var tag = document.createElement('script'),
firstScriptTag = document.getElementsByTagName('script')[0],
player;
tag.src = "https://www.youtube.com/player_api";
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
function onYouTubePlayerAPIReady() {
player = new YT.Player('ytplayer', {
height: height,
width: width,
videoId: yt_id,
playerVars: {
wmode: "transparent",
controls: 0,
showinfo: 0,
rel: 0,
modestbranding: 1,
iv_load_policy: 3 //anottations
},
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
};
function onPlayerReady(event) {
//code here
//I want to use this code even when the player is loaded after the page is loaded (when the user clicks a related video at the bottom)
}
function onPlayerStateChange(event) {
//here too
}
insert_frame.js
var tag = document.createElement('script'),
firstScriptTag = document.getElementsByTagName('script')[0],
player;
tag.src = "https://www.youtube.com/player_api";
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
player = new YT.Player('ytplayer', {
height: height,
width: width,
videoId: yt_id,
playerVars: {
wmode: "transparent",
controls: 0,
showinfo: 0,

modestbranding: 1,
iv_load_policy: 3 //anottations
},
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});

How can I insert the iframe in page and use the same function I use as
it was loaded from the beginning. ?
If i understand correctly, you want to do that because some videos ID on the url may be false and the player iframe will not play the video.
Well you don't need insert a frame just because a video ID exist when use click on a related videoo the bottom, use onError parameter from YouTube Player API.
This event fires if an error occurs in the player. The API will pass
an event object to the event listener function. That object's data
property will specify an integer that identifies the type of error
that occurred. ...
If the videoID on the url doesn't exist an error will be send. Just hide the player for example and show it when the user click on a related video on the bottom.
With this solution you only need to load the player one and only one time without insert a frame into the code even if the id is wrong. A sample solution.
I made you a little example with a wrong videoID :
HTML
<!DOCTYPE html>
<html>
<head>
<script src="//code.jquery.com/jquery-2.1.1.min.js"></script>
<meta charset="utf-8">
<title>JS Bin</title>
</head>
<body>
<div id="player"></div>
</body>
</html>
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);
// 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: 'l-gQLqv9f4',
events: {
'onError': onPlayerError,
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
// 4. The API will call this function when the video player is ready.
function onPlayerReady(event) {
$('#player').show();
event.target.playVideo();
}
// 5. The API calls this function when the player's state changes.
function onPlayerStateChange(event) {
if (event.data == YT.PlayerState.PLAYING) {
}
}
function stopVideo() {
player.stopVideo();
}
function onPlayerError() {
console.log("error on the video id. Iframe is hiding");
$('#player').hide(); //or do what you want
}

How do you mute an embedded Youtube player?

I'm experimenting with the Youtube player but I can't get it to mute by default.
function onPlayerReady() {
player.playVideo();
// Mute?!
player.mute();
player.setVolume(0);
}
How do I mute it from the start?
Fiddle
Update:
JavaScript Player API is deprecated.
Use iframe Embeds instead.

Turns out player.mute() works fine. It only needed the parameter enablejsapi=1. Initial test in the fiddle didn't work because the player initiation had an error. The following works.
HTML:
<iframe id="ytplayer" type="text/html" src="https://www.youtube-nocookie.com/embed/zJ7hUvU-d2Q?rel=0&enablejsapi=1&autoplay=1&controls=0&showinfo=0&loop=1&iv_load_policy=3" frameborder="0" allowfullscreen></iframe>
JS:
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('ytplayer', {
events: {
'onReady': onPlayerReady
}
});
}
function onPlayerReady(event) {
player.mute();
player.playVideo();
}
Fiddle
Credit to Gagandeep Singh and Anton King for pointing to enablejsapi=1

All above answers didn't work for me for some reason. It might be weird wordpress theme that I had to use or depreciated methods at Youtube API, I'm not sure. The only way of muting the player was to insert the code below into tag.
// Loads 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);
// Replaces the 'ytplayer' element with an <iframe> and
// YouTube player after the API code downloads.
var player;
function onYouTubePlayerAPIReady() {
player = new YT.Player('ytplayer', {
height: '390',
width: '640',
videoId: 'YOUR_VIDEO_ID',
playerVars: {
autoplay: 1,
controls: 1,
disablekb: 1,
hl: 'ru-ru',
loop: 1,
modestbranding: 1,
showinfo: 0,
autohide: 1,
color: 'white',
iv_load_policy: 3,
theme: 'light',
rel: 0
},
events: {
'onReady': onPlayerReady,
}
});
}
function onPlayerReady(event){
player.mute();
}
<div id="ytplayer"></div>

It's important to note that YouTube API mandates you run this within your markup directly within a <script> tag, or via a standard document.onLoad() native listener and not as a named function.
Otherwise it will not natively bind the onYouTubeIframeAPIReady() function to the DOM.

Try below code
var youtubeplayer = iframe.getElementById('ytplayer');
youtubeplayer .setVolume(0);
And below is your fiddle updated version,
NOTE: Must include enablejsapi=1 in video url
var tag = document.createElement('script');
tag.src = "//www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('ytplayer', {
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
function onPlayerReady(event) {
player.playVideo();
// Mute?!
//player.mute(); instead of this use below
event.target.mute();
//player.setVolume(0);
}
DEMO
Hope this helps...
