Javascript 模式窗口未关闭问题

我已经使用HTML、CSS和JavaScript创建了一个模式，我可以一起打开两个模式窗口， 我可以一个接一个地关闭它们（即，关闭第二个窗口会使第一个窗口保持活动状态，就像我想要的那样）

在这之前一切都很好，没有问题

我首先附加这些工作代码，以便您以后可以将其与有缺陷的JavaScript代码进行比较：

let open_modals = [];

$(function() {

  // Get the button that opens the modal
  // read all the control of any type which has class as modal-button
  var btn = document.querySelectorAll(".modal-button");

  // All page modals
  var modals = document.querySelectorAll('.modal');

  // Get the <span> element that closes the modal
  var spans = document.getElementsByClassName("close");

  // When the user clicks the button, open the modal
  for (var i = 0; i < btn.length; i++) {
    btn[i].onclick = function(e) {
      e.preventDefault();
      modal = document.querySelector(e.target.getAttribute("href"));
      modal.style.display = "block";
      open_modals.push(modal.id);
    }
  }

  // When the user clicks on <span> (x), close the modal
  for (var i = 0; i < spans.length; i++) {
    spans[i].onclick = function() {
      for (var index in modals) {
        if (typeof modals[index].style !== 'undefined' && modals[index].id == open_modals[open_modals.length - 1]) {
          modals[index].style.display = "none";
          open_modals.pop();
        }
      }
    }
  }

  // When the user clicks anywhere outside of the modal, close it
  window.onclick = function(event) {
    if (event.target.classList.contains('modal')) {
      for (var index in modals) {
        if (typeof modals[index].style !== 'undefined' && modals[index].id == open_modals[open_modals.length - 1]) {
          modals[index].style.display = "none";
          open_modals.pop();

        }
      }
    }
  }
})

现在是我为什么发布这篇文章的真正问题了
我想在模态窗口关闭时添加底部滑动动画，所以我在CSS中定义了动画，并通过

setTimeout

函数在JavaScript中添加了相同的动画

现在我在这里成功地添加了动画，但我把事情搞砸了

如果同时打开两个模式窗口（首先打开一个窗口，然后通过该窗口正文中的文本打开第二个窗口），然后尝试逐个关闭它们

只有第二个窗口会关闭，第一个窗口根本不会关闭 （如果您只是打开第一个窗口并尝试将其关闭，那么效果相当不错。只有当两个窗口都打开时，第一个窗口的关闭活动才会出现问题）

现在，我在附加JavaScript代码的地方添加了

setTimeout

，并弄乱了导致上述问题的东西：

let open_modals = [];

$(function() {

  // Get the button that opens the modal
  // read all the control of any type which has class as modal-button
  var btn = document.querySelectorAll(".modal-button");

  // All page modals
  var modals = document.querySelectorAll('.modal');

  // Get the <span> element that closes the modal
  var spans = document.getElementsByClassName("close");

  // When the user clicks the button, open the modal
  for (var i = 0; i < btn.length; i++) {
    btn[i].onclick = function(e) {
      e.preventDefault();
      modal = document.querySelector(e.target.getAttribute("href"));
      modal.style.display = "block";
      open_modals.push(modal.id);
    }
  }

  // When the user clicks on <span> (x), close the modal
  for (var i = 0; i < spans.length; i++) {
    spans[i].onclick = function() {
      for (var index in modals) {
        if (typeof modals[index].style !== 'undefined' && modals[index].id == open_modals[open_modals.length - 1]) {
          modals[index].classList.add("modal-content-active");

          setTimeout(function(){
            for (var index in modals) {
            modals[index].classList.remove("modal-content-active");
            modal.style.display = "none";
            open_modals.pop();
            }
          },400);
        }
      }
    }
  }

  // When the user clicks anywhere outside of the modal, close it
  window.onclick = function(event) {
    if (event.target.classList.contains('modal')) {
      for (var index in modals) {
        if (typeof modals[index].style !== 'undefined' && modals[index].id == open_modals[open_modals.length - 1]) {
          modals[index].classList.add("modal-content-active");

          setTimeout(function(){
            for (var index in modals) {
            modals[index].classList.remove("modal-content-active");
            modal.style.display = "none";
            open_modals.pop();
            }
          },400);

        }
      }
    }
  }
})

let open_modals=[]；
$（函数（）{
//获取打开模式对话框的按钮
//读取任何类型的所有控件，该控件的类为模态按钮
var btn=document.queryselectoral（“.modal按钮”）；
//所有页面模态
var modals=document.querySelectorAll（'.modal'）；
//获取关闭模态的元素
var span=document.getElementsByClassName（“关闭”）；
//当用户单击该按钮时，打开模式对话框
对于（变量i=0；i

是否有人可以调整JavaScript代码，使其在使用我的

setTimeout

动画时修复上述问题？ （您可以将顶部没有设置超时动画的原始工作JavaScript与下面有错误的JavaScript代码进行比较，以便轻松完成此操作）

更新：控制台出现以下错误：

未捕获的TypeError:无法读取未定义的属性“remove”

使用底部提到的有缺陷的JavaScript代码

---

如果有人想看到被窃听的代码在这里运行-

这是因为你在

setTimeout

中弹出了所有打开的模态，你应该只弹出最新的模态。我在下面的代码片段中修复了您的代码：

let open_modals=[]；
$（函数（）{
//获取打开模式对话框的按钮
//读取任何类型的所有控件，该控件的类为模态按钮
var btn=document.queryselectoral（“.modal按钮”）；
//所有页面模态
var modals=document.querySelectorAll（'.modal'）；
//获取关闭模态的元素
var span=document.getElementsByClassName（“关闭”）；
//当用户单击该按钮时，打开模式对话框
