ライトボックス+画像オーバーレイのテキスト

Question

ズームしたときに各画像の下にカスタムテキストを追加するにはどうすればよいですか？今では、テキストがdivに表示された場合は完璧なソリューションは次のようになり

などaltテキストに基づいて、私はイメージで、さらにそれをカスタマイズしたいです。ここで

はcodepenです：

// 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{ 
 
\t background: linear-gradient(to bottom right, #b81d1d, #5F554C, #E4DFD8); 
 
\t font-family: "Open Sans", sans-serif;

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

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

    } 
 

 
    .lightbox > div {

Answer 1

あなたは隠されたdivを追加し、jQueryを使ってテキストをつかむことができます。

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

Forked example

Answer 2

私はこのためには、データの属性を使用できると思う：

<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> 

そして

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