在灯箱中打开不同的图像

Question

我在Bootstrap中有一个图像灯箱，我想要实现的是当用户点击图像时，弹出的图像会有所不同。

所以我会有拇指图标，当用户点击其中一个时，将显示完整的图像。所以代码就像：

<a href="full_Image_url" ..> <img src="thumb_img_url" ...></a>

我尝试使用其他图片的位置编辑<a href="#" ..>，但它没有工作..

var $lightbox = $('#lightbox');

$('[data-target="#lightbox"]').on('click', function(event) {
  var $img = $(this).find('img'),
    src = $img.attr('src'),
    alt = $img.attr('alt'),
    css = {
      'maxWidth': $(window).width() - 100,
      'maxHeight': $(window).height() - 100
    };

  $lightbox.find('.close').addClass('hidden');
  $lightbox.find('img').attr('src', src);
  $lightbox.find('img').attr('alt', alt);
  $lightbox.find('img').css(css);
});

$lightbox.on('shown.bs.modal', function(e) {
  var $img = $lightbox.find('img');

  $lightbox.find('.modal-dialog').css({
    'width': $img.width()
  });
  $lightbox.find('.close').removeClass('hidden');
});

＆＃13;

body {
  padding: 30px 0px;
}

#lightbox .modal-content {
  display: inline-block;
  text-align: center;

#lightbox .close {

Answer 1

您已附加事件处理程序以点击<a data-target="#lightbox'>的事件。你可以找到它的父div，然后是下一个兄弟div和里面的图像。最后一个div你可以成为第一个兄弟姐妹。像这样的东西：

＆＃13;

＆＃13;

var $lightbox = $('#lightbox');

$('[data-target="#lightbox"]').on('click', function(event) {
    var imageDiv = $(this).parent().is(':last-child') ? $(this).parent().siblings().first() : $(this).parent().next();
    var $img = $(imageDiv).find('img'),
    src = $img.attr('src'),
    alt = $img.attr('alt'),
    css = {
      'maxWidth': $(window).width() - 100 ,
      'maxHeight': $(window).height() - 100
    };

  $lightbox.find('.close').addClass('hidden');
  $lightbox.find('img').attr('src', src);
  $lightbox.find('img').attr('alt', alt);

});

$lightbox.on('shown.bs.modal', function(e) {
  var $img = $lightbox.find('img');

  $lightbox.find('.modal-dialog').css({
    'width': $img.width()
  });
  $lightbox.find('.close').removeClass('hidden');
});

＆＃13;

body {
  padding: 30px 0px;
}

#lightbox .modal-content {
  display: inline-block;
  text-align: center;
}

#lightbox .close {
  opacity: 1;
  color: rgb(255, 255, 255);
  background-color: rgb(25, 25, 25);
  padding: 5px 8px;
  border-radius: 30px;
  border: 2px solid rgb(255, 255, 255);
  position: absolute;
  top: -15px;
  right: -55px;
  z-index: 1032;
}
