图片叠加中的灯箱+文字

问题描述：

如何在放大时在每张图片下添加自定义文字？现在它基于alt文本，但我想用图像等对其进行更多定制。图片叠加中的灯箱+文字

完美的解决方案是将文本显示在div中。

这里是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{ 
 
\t background: linear-gradient(to bottom right, #b81d1d, #5F554C, #E4DFD8); 
 
\t font-family: "Open Sans", sans-serif; 
 
} 
 
.container{ 
 
\t max-width: 800px;

    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{ 
 
\t text-align: center; 
 
\t 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; 
 
    } 
 
}

您可以添加一个隐藏div并抓住与jQuery的文字。

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

Forked example

这是很棒的！当我在

Test

之间添加“img”时，它不会显示在叠加层中。它应该是一张小档案图片，显示谁拍了照片。有没有解决方案？ – Musa

我更新了演示。尝试点击第一张图片。 –

太棒了！非常感激。 – Musa

我觉得对于这一点，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>

然后你用这个在JS如下

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