Squarespace Add Popup Video To Background Image Modules using YUI, not jQuery

squarespacePopup.js

YUI().use('node', 'event', function (Y) { // use squarespace's preloaded YUI instead of loading jQuery just to make a popup. add this to the footer of your page in a snippet.
    var videoLink = ''; // link your links to their videos in the content. 
    var top = pageYOffset;
    var body = Y.one('body');
    var obj;
    var doClose = function(e) {
        e.preventDefault();
        var videoContent = document.getElementById('videoContent');
        videoContent.parentNode.removeChild(videoContent);
        Y.one('body').removeClass('sqs-lightbox-open');
        return false;
    };
    var doVideo = function(e) {
        Y.one('body').addClass('sqs-lightbox-open');  // squarespace thing which keeps user from scrolling. meh.
        top = pageYOffset; // set the top of the videoContent popup to the top of the screen.
        obj = Y.Node.create('<div class="yui3-lightbox2" id="videoContent" style="position:absolute;top:'+top+'px;left:0;width:100%;height:100%;z-index:9999909; opacity:1;background:rgba(0,0,0,0.6)"><div class="sqs-lightbox-slideshow" style="opacity:1;"><div class="sqs-lightbox-padder"><iframe src="'+videoLink+'" width="500" height="281" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen style="position:absolute;top:0;left0;width:100%;height:100%;z-index:2;"></iframe></div><a class="sqs-lightbox-close"></a></div></div>');
        body.insert(obj);
        closer = document.getElementsByClassName('sqs-lightbox-close');
        closer = Y.one('.sqs-lightbox-close');
        closer.on('click', doClose);
    };
    Y.all('.page-desc a').each(function(node){ // this is what I needed to utilize the links. Yours may/will be different.
        node.on('click', function(e){
            e.preventDefault();
            videoLink = (node.getAttribute("href"));
            doVideo(e);
            return false;
        })
    });
