Question

When using Angular 2, the `onYouTubeIframeAPIReady` function may not be able to locate the `YT` name, even if it is defined on the

As part of my efforts to track when a user pauses a YouTube video (link to the question), I have been utilizing the onYouTubeIframeAPIReady callback method in Angular2.

I am facing similar challenges as discussed here and here.

Following the recommendations, I resorted to using

(window as any).onYouTubeIframeAPIReady = function () {}

.

Within my onYouTubeIframeAPIReady function, the code looks like this:

function onYouTubeIframeAPIReady() {
  player = new YT.Player('video', {
    events: {
     'onReady': onPlayerReady,
     'onStateChange': onPlayerStateChange
    }
  });
}

However, I encounter the following error from my TypeScript linter:

Argument of type '{events: {'onReady':(event:any) => void; 'onStateChange': (event:any)=>void;};}' is not assignable to parameter of type 'PlayerOptions'

You can find my minimal example repository here:

cd dataJitsu
git checkout stackoverflow
npm install
ng serve

Answer №1

By utilizing window['YT'] in place of just YT, you can resolve this issue:

ngOnInit() {
  var player;

  window['onYouTubeIframeAPIReady'] = function() {
    player = new window['YT'].Player('video', {
      events: {
        'onReady': onPlayerReady,
        'onStateChange': onPlayerStateChange
      }
    });
  }

  function onPlayerStateChange(event){
    if (event.data == window['YT'].PlayerState.PAUSED) {
      console.log(player.getCurrentTime());
    }
  }

  function onPlayerReady(event) {
    document.getElementById("pause").addEventListener("click", function() {
      player.pauseVideo();
    });
    document.getElementById("play").addEventListener("click", function() {
      player.playVideo();
    });
  }

  if (!window['YT']){
    var tag = document.createElement('script');
    tag.src = "//www.youtube.com/player_api";
    var firstScriptTag = document.getElementsByTagName('script')[0];
    firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
  }
}
