switch between, item ids, and video/image/texts.

data-fancybox-group="gallery" title="ImagePreviewBtn">
<span class="glyphicon glyphicon-eye-open"></span> PreviewButton</a>

Maybe like this:

$(document).on("click", "#preview-button", function(e) {
    e.preventDefault();
    var _whatShow = $("#what-show").val();
    if (!_whatShow) return false;
    switch(_whatShow) {
        case 'image': _type ='inline'; _href='#imagePreview'; break;
        case 'video': _type ='iframe'; _href=$('#videoPreview').attr('src'); break;
        case 'text': _type ='inline'; _href='#textPreview'; break;
    }
   $.fancybox({
      href: _href,
      width: 730,
      height: 530,
      type: _type,
    }); 
});
