类型错误：player.b 未定义。我该如何解决？

Question

需要在代码中调整什么来解决这个问题？

代码： https://jsfiddle.net/0bnrg3k1/2/

    function onPlayerStateChange(event) {
    const player = event.target;
    const playerVars = player.b.b.playerVars;
    if (playerVars.loop && event.data === YT.PlayerState.ENDED) {
      player.seekTo(playerVars.start);
    }
  }

Answer 1

您需要使用player.g.g.playerVars，而不是使用player.b.b.playerVars。

function onPlayerStateChange(event) {
  const player = event.target;
  const playerVars = player.g.g.playerVars;
  if (playerVars.loop && event.data === YT.PlayerState.ENDED) {
    player.seekTo(playerVars.start);
  }
}
