Working with Photoswipe in meteor init() function not working properly

I keep getting an error that states “spectrum_photoswipe.js:63 Uncaught TypeError: Cannot read property ‘className’ of undefined” It’s refrencing this block of code:

 removeClass: function(el, className) { var reg = new RegExp('(\\s|^)' + className + '(\\s|$)');
  el.className = el.className.replace(reg, ' ').replace(/^\s\s*/, '').replace(/\s\s*$/, '');  }

My code is passing items and options correctly like so:

    var listingId = template.data.listingId,
    imgs = ListingCollection.findOne({_id: listingId}).images;
    var items = [];
    for(var i =0; i < imgs.length; i++) {
        var tempImg = new Image();
        tempImg.src = imgs[i];
        var itemObject = {"src": "", "w": "", "h": ""};
            itemObject.src = imgs[i];
            itemObject.w = tempImg.width;
            itemObject.h = tempImg.height;
        items[i] = itemObject;
    }
    var options = {
        index: 0,
        history: false,
        focus: false,
        showAnimationDuration: 0,
        hideAnimationDuration: 0
    };

    var gallery = new PhotoSwipe( pswpElement, PhotoSwipeUI_Default, items, options);
    gallery.init();

And I’ve checked to make sure that the pswp element is in the DOM. I’m not really sure what’s going on here. Any help would be greatly appreciated

Well, I’m not the plugin author 😃 Btw. in #1128 someone already mentioned issues with -- in comment. Glad you got it working!

Thank you! That was the issue, one of the commented out sections in the pswp uses – in the comment:

<!-- element will get class pswp__preloader--active when preloader is running -->

and that commented out the pswp__preloader class. You might want to consider changing that comment in the documentation. Thanks for the help!
