I am novice javascript developer. I have a bookmarklet that can get the current time of a youtube video.
javascript:(function(){
ytplayer = document.getElementById("movie_player");
var secs = ytplayer.getCurrentTime();
alert(`${secs}`);
})();
It works fine on youtube.com. However, when I apply the same logic to an iframe-based website (url here). According to youtube API reference, I use function onYouTubePlayerAPIReady(). but nothing happens when I run the bookmarklet. Here is the code
javascript:function onYouTubePlayerAPIReady() {
var ytplayer = new YT.Player('widget2');
var secs = ytplayer.getCurrentTime();
alert(`${secs}`);
}
Does any youtube API expert can spot the issue?
Here is the iframe of the sample youtube from the website
<iframe frameborder="0" allowfullscreen="1" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" title="YouTube video player" width="100%" height="100%" src="https://www.youtube.com/embed/eSWwIQzKsbY?autoplay=1&mute=0&controls=1&start=0&origin=https%3A%2F%2Fyou-tldr.com&playsinline=1&showinfo=0&rel=0&iv_load_policy=3&modestbranding=1&enablejsapi=1&widgetid=1" id="widget2" data-gtm-yt-inspected-1_25="true"></iframe>
Yes. I have a similar need. I don't think you called the onYouTubeIframeAPIReady() function. This is the working code.
function onYouTubeIframeAPIReady() {
var player = new YT.Player('widget2', {//The id of the div containing the iframe. Should be changed based on the page you're at and the i they gave their player
events: {
'onStateChange': onPlayerStateChange//Event listener, fires onPlayerStateChange function whenever the state of the video changes, paused or played
}
});
function onPlayerStateChange() {
currentTime = player.playerInfo.currentTime;//Current Time saved
if (player.playerInfo.playerState === 2) {//If video paused, console.log the time
console.log(currentTime);
}
}
}
onYouTubeIframeAPIReady();//Initial call to the function
