javascript - jQuery - 显示/隐藏多个模式

Question

如何使用每个 .button 的 id 和 data-id 打开 .modal对于每个模态？

如果任一 .modal 打开并且我单击另一个 .button，我希望模式切换(打开的关闭，关闭的打开)。

$('.button').on('click', function() {
  $('.modal').toggleClass('active');
});
$(document).on("click", function(e) {
  if (($(".modal").hasClass("active")) && (!$(".modal, .modal *, .button").is(e.target))) {
    $(".modal").toggleClass("active");
  }
});
$(window).scroll(function() {
  $('.modal').removeClass('active');
});

.button {
  height: 30px;
}

.header {
  height: 15px;
  background: #eee;
}

.modal {
  position: fixed;
  top: 72px;
  right: 15px;
  z-index: 6;
  opacity: 0;
  visibility: hidden;
  transform: scale(0.5);
  transform-origin: top right;
  transition: 0.15s;
  box-shadow: 0 1.5px 4px rgba(0, 0, 0, 0.24), 0 1.5px 6px rgba(0, 0, 0, 0.12);
}

.modal:after {
  content: "";
  width: 15px;
  height: 15px;
  background: inherit;
  position: absolute;
  background: #eee;
  top: -6px;
  right: 8px;
  opacity: 0;
  visibility: hidden;
  transform: rotate(45deg) scale(0.5);
  transition: 0.15s;
}

.modal.active {
  opacity: 1;
  visibility: visible;
  transform: scale(1);
}

.modal.active:after {
  opacity: 1;
  visibility: visible;
  transform: rotate(45deg) scale(1);
}

您可以将按钮 .prop('id') 的 id 与模态 .data('id') 的数据 id 进行比较并切换.active 类基于值的相等性。您可以通过使用 $(.modal).each 循环模式并利用 .toggleClass() 函数的状态参数来隐藏所有不显示的内容，从而准确地切换类'匹配按钮 ID 并显示匹配的那个。

您的示例代码似乎有两个问题:

• 单击 html 会在所有模式上切换 .active 类，因此我将其切换为 removeClass。
• 两个模态框都显示 Google，所以我将 apple 模态框切换为 Apple。

$('.button').on('click', function() {
  const id = $(this).prop('id');
  $('.modal').each(function() {
    $(this).toggleClass('active', $(this).data('id') == id);
  });
});
$(document).on("click", function(e) {
  if (($(".modal").hasClass("active")) && (!$(".modal, .modal *, .button").is(e.target))) {
    $(".modal").removeClass("active");
  }
});
$(window).scroll(function() {
  $('.modal').removeClass('active');
});

.button {
  height: 30px;
  cursor: pointer;
}

.header {
  height: 15px;
  background: #eee;
}

.modal {
  position: fixed;
  top: 72px;
  right: 15px;
  z-index: 6;
  opacity: 0;
  visibility: hidden;
  transform: scale(0.5);
  transform-origin: top right;
  transition: 0.15s;
  box-shadow: 0 1.5px 4px rgba(0, 0, 0, 0.24), 0 1.5px 6px rgba(0, 0, 0, 0.12);
}

.modal:after {
  content: "";
  width: 15px;
  height: 15px;
  background: inherit;
  position: absolute;
  background: #eee;
  top: -6px;
  right: 8px;
  opacity: 0;
  visibility: hidden;
  transform: rotate(45deg) scale(0.5);
  transition: 0.15s;
}

.modal.active {
  opacity: 1;
  visibility: visible;
  transform: scale(1);
}

.modal.active:after {
  opacity: 1;
  visibility: visible;
  transform: rotate(45deg) scale(1);
}
