您好，上面的灯箱代码有问题。

它显然只显示最新的信息，例如。

                <a href="#" class="lightbox">Open Lightbox</a>

                <div class="backdrop"></div>
                <div class="box"><div class="close">x</div>This is the lightbox!!!</div>




                <a href="#" class="lightbox">Open Lightbox</a>

                <div class="backdrop"></div>
                <div class="box"><div class="close">x</div>This is the lightbox123456!!!</div>

会显示This is the lightbox123456!!!无论您点击什么。

请帮忙，谢谢。

其实这两个都显示了，如果你把.box的位置改成relative，你可以看到两个框都出现了。我创建了一个 jsfiddle 来显示效果。

因为你只希望它在锚点之后显示框，你可以这样做：

将.backdrop移动到正文的最后，只保留一个，因为它不会与您单击的锚点一起。
直接在锚点后使用.next()到select.box，然后使用.add添加.backdrop组.
为它们制作动画。

如果 .backdrop 因您单击的锚点而异，我建议将 .box 和 .backdrop 都包装到容器中，然后使用 $(this).next('.container').find('.box, .backdrop') 获取目标。或者也将锚点包裹在容器中，然后使用 $(this).siblings('.box, .backdrop') 到 select.

$(document).ready(function() {

  $('.lightbox').click(function() {
    // Get the target box, and the only backdrop
    
    // Because they will apply different opacity, we have to get them separately first.
    var $box = $(this).next('.box');
    var $backdrop = $('.backdrop');
    
    // Group them.
    var $targets = $box.add($backdrop);
    
    // Ensure the targets's display.
    $targets.css('display', 'block');
    
    // Separate the animation of each element if you want different parameters. or chain them.
    $backdrop.animate({
      'opacity': '.50'
    }, 300, 'linear');
    $box.animate({
      'opacity': '1.00'
    }, 300, 'linear');
    $targets.css('display', 'block');
  });

  $('.close').click(function() {
    close_box();
  });

  $('.backdrop').click(function() {
    close_box();
  });

});

function close_box() {
  $('.backdrop, .box').animate({
    'opacity': '0'
  }, 300, 'linear', function() {
    $('.backdrop, .box').css('display', 'none');
  });
}

body {
  font-family: Helvetica, Arial;
}
.backdrop {
  position: absolute;
  top: 0px;
  left: 0px;
  width: 100%;
  height: 100%;
  background: #000;
  opacity: .0;
  filter: alpha(opacity=0);
  z-index: 50;
  display: none;
}
.box {
  position: absolute;
  top: 20%;
  left: 30%;
  width: 500px;
  height: 300px;
  background: #ffffff;
  z-index: 51;
  padding: 10px;
  -webkit-border-radius: 5px;
  -moz-border-radius: 5px;
  border-radius: 5px;
  -moz-box-shadow: 0px 0px 5px #444444;
  -webkit-box-shadow: 0px 0px 5px #444444;
  box-shadow: 0px 0px 5px #444444;
  display: none;
}
.close {
  float: right;
  margin-right: 6px;
  cursor: pointer;
}
