var iframe=document.getElementById('videoPlayer');
var player = new Vimeo.Player('videoPlayer');

var onPlay = function(data) {
    console.log('Video is Played');
}

var onEnd = function(data) {
    console.log('Video is ended');
}

this.player.on('play', onPlay);
this.player.on('ended', onEnd);

var nextBtn = document.querySelector('button#next');

var playNextVideo = function(event) {
    console.log('Playing Next Video');
    player.element.src = 'https://player.vimeo.com/video/234797489';
}

nextBtn.addEventListener('click', playNextVideo.bind(this));
