Lightbox + Text under Image Overlay

Question

How can I add custom text under each image when it's zoomed in? Now it is based on the alt text, but I want to customize it even more with images etc.

The perfect solution would be if the text was displayed in a div.

Here is the codepen:

// Create a lightbox
(function() {
  var $lightbox = $("<div class='lightbox'></div>");
  var $img = $("<img>");
  var $caption = $("<p class='caption'></p>");

  // Add image and caption to lightbox

  $lightbox
    .append($img)
    .append($caption);

  // Add lighbox to document

  $('body').append($lightbox);

  $('.lightbox-gallery img').click(function(e) {
    e.preventDefault();

    // Get image link and description
    var src = $(this).attr("src");
    var cap = $(this).attr("alt");

    // Add data to lighbox

    $img.attr('src', src);
    $caption.text(cap);

    // Show lightbox

    $lightbox.fadeIn('fast');

    $lightbox.click(function() {
      $lightbox.fadeOut('fast');
    });
  });

}());

body{
	background: linear-gradient(to bottom right, #b81d1d, #5F554C, #E4DFD8);
	font-family: "Open Sans", sans-serif;
}
.container{
	max-width: 800px;
	margin: 5% auto;
	padding: 20px;
	background-color: #fff;
	overflow: hidden;
	box-sizing: border-box;
  box-shadow: 0 15px 20px -15px rgba(0, 0, 0, 0.3), 0 35px 50px -25px rgba(0, 0, 0, 0.3), 0 85px 60px -25px rgba(0, 0, 0, 0.1);
}

.text-center{
	text-align: center;
	margin-bottom: 1em;
}

.lightbox-gallery {
  display: flex;
  flex-direction: row;
  flex-wrap: wrap;
  justify-content: center;
}

.lightbox-gallery div > img {
  max-width: 100%;
  display: block;
}

.lightbox-gallery div {
  margin: 10px;
  flex-basis: 180px;
}

@media only screen and (max-width: 480px) {
  .lightbox-gallery {
    flex-direction: column;
    align-items: center;
  }

  .lightbox > div {
    margin-bottom: 10px;
  }
}

.lightbox{
	display: none;
	width: 100%;
	height: 100%;
	background-color: rgba(0,0,0,.7);
	position: fixed;
	top: 0;
	left: 0;
	z-index: 20;
	padding-top: 30px;
	box-sizing: border-box;
}

.lightbox img{
	display: block;
  margin: auto;
}

.lightbox .caption{
	margin: 15px auto;
	width: 50%;
	text-align: center;
	font-size: 1em;
	line-height: 1.5;

	color: #eee;

Answer 1

I think for this you could use data attributes:

<div><img id="myImg" src="http://placehold.it/300/f1b702/fff&text=image1" alt="my alt" data-caption="my Caption or whatever you want"></div>

And then you use this in js as follows

var myCaption = $('#myImg').data('caption');
// use this as you please

You can add a hidden div and grab the text with jQuery.

 <div class="js-text text">Test</div>
 var txt = $(this).parent().find('.js-text').text()
