Javascript doesn't work on ajax post - javascript

I'm using Youtube Iframe API and using their script the player loads fine. But when I do an ajax call to the php file containing javascript code to run the player, it doesn't execute.
function get_content(song_id,url,song_title) {
if (song_id == null)
return;
document.title = song_title + browser_title_suffix;
$.get('/ajax/player.php',{song_id:song_id}, function(data) {
$('#main_content').html(data).css({'opacity':0}).animate({'opacity':1});
});
}
/ajax/player.php contains this code - https://developers.google.com/youtube/iframe_api_reference#Loading_a_Video_Player
However, the player does not again. I even tried player.remove() but that didn't help either.
UPDATE 1:
My PHP file:
var tag = document.createElement('script');
tag.src = "//www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
$(document).ready(function(){
get_content('.$row[song_id].',null,"'.$row[title].'");
});
</script>
My javascript file:
function get_content(song_id,url,song_title) {
if (song_id != null) {
$.get('/ajax/player.php',{song_id:song_id}, function(data) {
video_id = data;
player = new YT.Player('player', {
height: '390',
width: '640',
videoId: video_id,
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
});
}
}
However, the video player does not load.

You can't get javascript via ajax and then run the just recieved javascript. What you want to do is just send the youtube video id via ajax and then use a function like this to place the player:
function get_content(song_id,url,song_title) {
if (song_id != null) {
$.get('/ajax/player.php',{song_id:song_id}, function(data) {
video_id = data;
player = new YT.Player('player', {
height: '390',
width: '640',
videoId: video_id,
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
});
}
}
Better yet, try JSON to send and recieve data via Jquery.

Youtube javascript load another video when video ends

I want to play another video, which I will get from my database, but I try it with some sample, which is not working at all, here is my sample code:
<script>
// create youtube player
var player;
function onYouTubePlayerAPIReady(id) {
if (id == null) {var t = '0Bmhjf0rKe8';}
player = new YT.Player('player', {
height: '390',
width: '640',
videoId: t,
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
// autoplay video
function onPlayerReady(event) {
event.target.playVideo();
}
// when video ends
function onPlayerStateChange(event) {
if(event.data === 0) {
// Here I want to call function again, function executes, but video will not played
onYouTubePlayerAPIReady('yeDkcSZta2Y');
}
}
There you can see, when video ends I call onYouTubePlayerAPIReady() with new video ID, it executes as well, but video do not play. I think it will be because the onPlayerReady() do not executes, or something.
How to fix this, or what change to work it properly?
Here is an example that works. Call queueVideo() to load a string containing comma separated video ids of all the videos that you want to play or just one video. When there are no video left in the queue, this plays the default video '0Bmhjf0rKe8'. I never use onPlayerReady(). In fact, if I remember correctly, it was never called so I implemented using the technique shown below.
<script type="text/javascript">
// 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);
//
// Replaces the 'ytplayer' element with an <iframe> and
// YouTube player after the API code downloads.
var player;
var videosQueuedCount;
function onYouTubePlayerAPIReady() {
videosQueuedCount = 1;
var vars = {
autoplay: 1,
enablejsapi: 1,
controls: 1
}
player = new YT.Player('ytplayer', {
height: '390',
width: '640',
playerVars: vars,
videoId:'0Bmhjf0rKe8',
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
function onPlayerReady(evt) {
}
function playVideo(VID) {
window.top.scrollTo(0,410);
videosQueuedCount = 1;
player.loadVideoById(VID);
}
function queueVideo(queuedCount,VID) {
window.top.scrollTo(0,410);
videosQueuedCount = queuedCount;
player.loadPlaylist(VID);
player.playVideo();
}
function onPlayerStateChange(event) {
if (event.data == YT.PlayerState.ENDED) {
videosQueuedCount -= 1;
if (videosQueuedCount < 1) {
videosQueuedCount = 1;
playVideo('0Bmhjf0rKe8');
}
}
}
</script>
<div class="video-container"><div id="ytplayer"></div></div>

Youtube iFrame API how do I invoke IframeAPIReady function after getting list of videos

I am making simple Youtube Video Player myself, and I'd like to know how to invoke onYouTubeIframeAPIReady() after I get a list of videos.
What I like to do is display the first video in list as initial video.
In my html somewhere:
<script src="//www.youtube.com/iframe_api"></script>
This is initial iframe embed code from official sample code:
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('player-box', {
// height: '390',
// width: '640',
videoId: {FIRST_VIDEO_ID},
events: {
'onReady': onPlayerReady,
// 'onStateChange': onPlayerStateChange
}
});
}
Here is how I get a list of vids:
$.getJSON(
'https://www.googleapis.com/youtube/v3/videos',
{
part: 'snippet',
id: {VIDEO_IDs},
key: {MY_API_KEY},
},
function(data) {
var items = data.items;
console.log(data);
// cannot put onYouTubeIframeAPIReady here...
}
);
I guess I cannot put onYouTubeIframeAPIReady() as $.getJSON's callback, since it is called outside the script.
I kinda solve this problem myself.
I wrapped everything inside var onYouTubeIframeAPIReady = function() {...
Here's how I done:
var onYouTubeIframeAPIReady = function() {
var videos = '{VIDEO_ID1}, {VIDEO_ID2}, {VIDEO_ID3}';
$.getJSON(
'https://www.googleapis.com/youtube/v3/videos',
{
part: 'snippet',
id: videos,
key: {MY_API_KEY},
},
function(data) {
var items = data.items;
console.log(items);
$.each(items, function(i, video){
console.log(video);
});
var player;
player = new YT.Player('player-box', {
// height: '390',
// width: '640',
videoId: {INITIAL_VIDEO_ID},
events: {
'onReady': onPlayerReady,
// 'onStateChange': onPlayerStateChange
}
});
function onPlayerReady(event) {
event.target.playVideo();
}
var done = false;
function onPlayerStateChange(event) {
// console.log(event.data);
// if (event.data == YT.PlayerState.PLAYING && !done) {
// everytime change vids playing for 6secs then stop
if (event.data == YT.PlayerState.PLAYING) {
setTimeout(stopVideo, 6000);
done = true;
}
}
function stopVideo() {
player.stopVideo();
}
}//$.getJSON callback
}

Youtube iFrame APi won't fire onPlayerStateChange function

so I'm using the Youtube iFrame API to give me an alert when the video stops playing with the following code:
<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', {
height: '390',
width: '640',
videoId: '0Bmhjf0rKe8',
playerVars: {
'autoplay': 1,
'controls': 1,
'html5': 1
},
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
var playerReady = false;
// 4. The API will call this function when the video player is ready.
function onPlayerReady(event) {
playerReady = true;
}
// 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.
function onPlayerStateChange(event) {
if (event.data == YT.PlayerState.ENDED) {
alert('done');
}
}
I tried this same code on jsfiddle: (http://jsfiddle.net/QtBlueWaffle/8bpQ8/1/) and it works fine there. Doesn't work on my local machine though. Any ideas?

Selecting a random element of array to set a Youtube videoId API

I'm trying to set up an array of videoId's to be able to choose from to be randomly loaded. I tried to add the videos array as a videoId, and it didn't work. I'm kind of a JS newb, so I'm not really sure what it is I should be passing back for this. I got as far as this:
<div id="player"></div>
<script>
function rotateYT() {
var videos = [
'ZMnjkcvjN-E',
'RFQfSMbLCWw',
];
var index=Math.floor(Math.random() * videos.length);
}
// 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: '300',
width: '300',
videoId: videos[index], //where I'm trying to get the random videos
events: {
'onReady': onPlayerReady,
}
});
}
// 4. The API will call this function when the video player is ready.
function onPlayerReady(event) {
event.target.playVideo();
event.target.mute();
event.target.setPlaybackQuality('small');
}
</script>
The function needs to return the selected video ID:
function rotateYT() {
var videos = [
'ZMnjkcvjN-E',
'RFQfSMbLCWw',
];
var index=Math.floor(Math.random() * videos.length);
return videos[index];
}
Then you need to call it in onYouTubeIframeAPIReady:
function onYouTubeIframeAPIReady() {
var videoID = rotateYT();
player = new YT.Player('player', {
height: '300',
width: '300',
videoId: videoID,
events: {
'onReady': onPlayerReady,
}
});
}

},
type: 'image'
// You may add options here, they're exactly the same as for $.fn.magnificPopup call
// Note that some settings that rely on click event (like disableOn or midClick) will not work here
}, 0); }
}
</script>
