javascript - 如何让 Css-Only 灯箱在单个页面上处理多个图像？

Question

我能否将纯 CSS 灯箱功能应用于单个页面上的一系列不同图像？

我提供了一个显示 3 个不同图像的示例，并应用了灯箱功能；但是，一旦提示灯箱，所有图像似乎只抓取列出的第一张图像。

引用下面的片段:

$('.pic > img').each(function() {
  var srcToCopy = $(this).attr('src');
  $(this).closest('.container').find('.imgsrc').attr('src', srcToCopy);

});

.pic,
#imgsrc {
  display: inline-block;
}

img {
  width: 100px
}

a {
  display: inline-block;
  line-height: 0;
}

.container {
  display: block;
  width: 100%;
  line-height: 0;
}

.customlightbox {
  top: 0%;
  bottom: 0%;
  box-sizing: border-box;
  position: fixed;
  left: 0;
  right: 0;
  background: rgba(0, 0, 0, 0.7);
  z-index: -5;
  opacity: 0;
}

.customlightbox-imgwrap {
  width: 100%;
  height: 100%;
  padding: 20px;
  box-sizing: border-box;
  position: relative;
  text-align: center;
}

.customlightbox img {
  width: auto;
  margin: auto;
  max-width: 100%;
  max-height: 100%;
  opacity: 0;
  position: relative;
  top: 50%;
  transform: translateY(-50%);
}

#customlightbox-controls {
  box-sizing: border-box;
  position: fixed;
  height: 50px;
  width: 50px;
  top: -50px;
  right: -3px;
  z-index: 5;
  border-left: 2px solid white;
  border-bottom: 2px solid white;
  opacity: .7;
}

#close-customlightbox {
  display: block;
  position: absolute;
  overflow: hidden;
  height: 30px;
  width: 30px;
  right: 10px;
  top: 10px;
  -webkit-transform: rotate(45deg);
  -moz-transform: rotate(45deg);
  -ms-transform: rotate(45deg);
  -o-transform: rotate(45deg);
  transform: rotate(45deg);
}

#close-customlightbox:before {
  content: "";
  display: block;
  position: absolute;
  height: 0px;
  width: 2px;
  left: 14px;
  top: 0;
  background: white;
  border-radius: 2px;
}

#close-customlightbox:after {
  content: "";
  display: block;
  position: absolute;
  width: 0px;
  height: 2px;
  top: 14px;
  left: 0;
  background: white;
  border-radius: 2px;
}

.customlightbox:target {
  z-index: 4;
  opacity: 1;
  display: inline-block;
}

.customlightbox:target img {
  opacity: 1;
}

.customlightbox:target ~ #customlightbox-controls {
  top: -3px;
}

.customlightbox:target ~ #customlightbox-controls #close-customlightbox:after {
  width: 30px;
}

.customlightbox:target ~ #customlightbox-controls #close-customlightbox:before {
  height: 30px;
}

.lb-animate {
  -webkit-transition: 0.5s ease-in-out;

您只需要为灯箱创建一个div，并根据图片的点击更换图片来源

$('.pic > img').click(function() {
  var srcToCopy = $(this).attr('src');
  $('body').find('.imgsrc').attr('src', srcToCopy);
});

.pic,
#imgsrc {
  display: inline-block;
}

img {
  width: 100px
}

a {
  display: inline-block;
  line-height: 0;
}

.container {
  display: block;
  width: 100%;
  line-height: 0;
}

.customlightbox {
  top: 0%;
  bottom: 0%;
  box-sizing: border-box;
  position: fixed;
  left: 0;
  right: 0;
  background: rgba(0, 0, 0, 0.7);
  z-index: -5;
  opacity: 0;
}

.customlightbox-imgwrap {
  width: 100%;
  height: 100%;
  padding: 20px;
  box-sizing: border-box;
  position: relative;
  text-align: center;
}

.customlightbox img {
  width: auto;
  margin: auto;
  max-width: 100%;
  max-height: 100%;
  opacity: 0;
  position: relative;
  top: 50%;
  transform: translateY(-50%);
}

#customlightbox-controls {
  box-sizing: border-box;
  position: fixed;
  height: 50px;
  width: 50px;
  top: -50px;
  right: -3px;
  z-index: 5;
  border-left: 2px solid white;
  border-bottom: 2px solid white;
  opacity: .7;
}

#close-customlightbox {
  display: block;
  position: absolute;
  overflow: hidden;
  height: 30px;
  width: 30px;
  right: 10px;
  top: 10px;
  -webkit-transform: rotate(45deg);
  -moz-transform: rotate(45deg);
  -ms-transform: rotate(45deg);
  -o-transform: rotate(45deg);
  transform: rotate(45deg);
}

#close-customlightbox:before {
  content: "";
  display: block;
  position: absolute;
  height: 0px;
  width: 2px;
  left: 14px;
  top: 0;
  background: white;
  border-radius: 2px;
}

#close-customlightbox:after {
  content: "";
  display: block;
  position: absolute;
  width: 0px;
  height: 2px;
  top: 14px;
  left: 0;
  background: white;
  border-radius: 2px;
}

.customlightbox:target {
  z-index: 4;
  opacity: 1;
  display: inline-block;
}

.customlightbox:target img {
  opacity: 1;
}

.customlightbox:target~#customlightbox-controls {
  top: -3px;
}

.customlightbox:target~#customlightbox-controls #close-customlightbox:after {
  width: 30px;
}

.customlightbox:target~#customlightbox-controls #close-customlightbox:before {
  height: 30px;
}

.lb-animate {
  -webkit-transition: 0.5s ease-in-out;
  -moz-transition: 0.5s ease-in-out;
  -ms-transition: 0.5s ease-in-out;
  -o-transition: 0.5s ease-in-out;
  transition: 0.5s ease-in-out;
