灯箱 + 图像叠加层下的文本

Question

当图片放大时，如何在每张图片下方添加自定义文本？现在它基于 alt 文本，但我想用图像等进一步自定义它。

完美的解决方案是将文本显示在 div。

这是代码笔：

// 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;
 font-weight: 700;
 color: #eee;
}

Answer 1

您可以添加一个隐藏的 div 并使用 jQuery 抓取文本。

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

Answer 2

我想你可以使用数据属性：

<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>

然后在js中使用如下

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