close popup after vimeo video finish

Question

I have implemented a little script to close magnific popup when a vimeo video finish using froogaloop,

this is my code:

var SlampLightbox = (function(undefined){

    var mp; //store Magnific Popup global object

    var mp_exixts = function(){
        if( $.fn.magnificPopup ){
            mp = $.magnificPopup.instance
            return true;
        }else{
            return false;
        }
    }

    var open_from_hash = function(){
        var hash = window.location.hash.slice(1); //cache hash

        if( hash.length  > 1 && hash != '#!'){
            var mark_pos = hash.indexOf('?');
            if( mark_pos != -1)
                hash = hash.substring(0, mark_pos);

            var selector = 'a[name='+hash+']';
            $(selector).click(); //trigger click event on the element to open magnificPopup

         }
    }

    var open = function($element){
        $element.magnificPopup({
            delegate: 'a',
            type: 'iframe',
            tLoading: '',
            iframe: {
              markup: '<div class="slamp-mfp-iframe-scaler">'+
                        '<button title="Close (Esc)" type="button" class="slamp-mfp-close">x</button>'+
                        '<iframe id="vimeoplayer" class="mfp-iframe" frameborder="0" allowfullscreen></iframe>'+
                      '</div>', // HTML markup of popup, `mfp-close` will be replaced by the close button
     patterns: {
       vimeo:{
          index: 'vimeo.com/',
          id: '/',
          src: '//player.vimeo.com/video/%id%?autoplay=1&api=1&player_id=vimeoplayer'
       }
     }
            },
            callbacks: {
                markupParse: function(template, values, item) {

        _attachVideoEvent(template, values, item);


                }

            }
        })
    }

    var _close = function(){
        mp.close();
    }

var _attachVideoEvent = function(template, values, item){

    var playerOrigin = '*';
    var player = $f( template.find("iframe")[0] );

    if( player.length == 0 )
    return;

    var onFinish = function(){
        _close();
    }

    player.addEvent('ready', function() {
        player.addEvent('finish', onFinish);
    });



  }

    return {
        init: function($element){//input must be a jQuery object

            if( mp_exixts() ){
                open($element);

                if( $element.length == 0)
                    return;

                open_from_hash(); //open a video specified in the hash, if any

                $(document.body).on('click', '.slamp-mfp-close', _close);
            }else{
                console.error("MagnificPopup doesn't exists");
                return false;
            }

            },
        mp: mp
    }
})(undefined);
window.SlampLightbox = SlampLightbox; //global function

you can view it here:

but it works just once, because the second time I click on the img I get a

javascript error:

VM983 froogaloop2.min.js:1 Uncaught TypeError: Cannot read property 'postMessage' of null

but I can't understand why, it's my fault? o a froogaloop bug? please help me to understand

thanks

Try this codepen ;)

Here when we attach _attachVideoEvent it do some postMessage thing which throws an error and JavaScript execution breaks; We have delayed this binding so that pop open and then we do binding thing. It still throw error but no problem.
