您好，我上面的灯箱代码存在问题。

例如，它显然只显示最新信息。

                <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>

它会显示这是lightbox123456 !!!不管你点击什么。

请帮助，谢谢。

Answer 1

事实上，如果您将.box的位置更改为relative，则可以看到两个框都显示出来。我创建了jsfiddle来显示效果。

由于您只希望它在锚点后显示方框，您可以执行以下操作：

将.backdrop移动到身体的最后一个，只保留一个，因为它不会与您点击的锚点相关。
使用.next()直接在锚点后选择.box，然后使用.add将.backdrop添加到群组。
为他们制作动画。

如果.backdrop因您点击的锚点而异，我建议将.box和.backdrop包装到容器中，然后使用$(this).next('.container').find('.box, .backdrop')获取目标。或者也可以将锚点包装在容器中，然后使用$(this).siblings('.box, .backdrop')进行选择。

$(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');
  });
}
