是否有一个OnStateChange事件仅用于初始视频播放

Question

试图在初始视频播放上实现Google跟踪。

API给出6个状态

-1 (unstarted)
0 (ended)
1 (playing)
2 (paused)
3 (buffering)
5 (video cued).

但是我正在使用的状态（1：播放）在每次视频点击上触发。我只想跟踪最初的播放事件。

这就是我到目前为止的。

asyncYouTubeApiLoad();
getVideoTrackingValues();

function getVideoTrackingValues() {
    $player = $('#player'),
    $yt_trackValue = $player.data('tracking-value');
}
executeYouTubeReady();
function executeYouTubeReady() {
    // Wait for API
    setTimeout(function() {
        onYouTubeIframeAPIReady();
    }, 200);
}
function onYouTubeIframeAPIReady() {
  player = new YT.Player('player', {
    events: {
      'onStateChange': onPlayerStateChange
    }
  });
}
function onPlayerStateChange(event) {
    // On Play
    if (event.data = 1) {
        fireVideoEventTracking('video_play');
    }
    // On End
    else if (event.data = 0) {
        fireVideoEventTracking('video_complete');
    }
}
function fireVideoEventTracking(eventType) {
    _gaq.push(['_trackEvent', 'video', eventType, $yt_trackValue]);                    
}

最终将布尔值添加到现有方法中并对其进行检查。

var initialLoad = false;
    function onYouTubeIframeAPIReady() {
      player = new YT.Player('player', {
        events: {
          'onReady': onPlayerReady,
          'onStateChange': onPlayerStateChange
        }
      });
    }
    function onPlayerReady() {
        initialLoad = true;
    }
    function onPlayerStateChange(event) {
        console.log(event.data);
        // On Play
        if (event.data == 1 && initialLoad) {
            fireVideoEventTracking('video_play');
            initialLoad = false;
        } else if (event.data == 0) {
            fireVideoEventTracking('video_complete');
        }
    }
