我正在写一些东西像windows7的概念。双击一个图标一个窗口将打开。如果你双击一个图标，例如4倍4窗口将为您打开。当我们有许多打开的窗口时，当你点击一个窗口它的z索引应该增加，并显示在其他打开的窗口。我的问题是，我不能写代码为它的z-索引，实际上当你点击一个图标时，它只打开一次，当你再次点击时，没有发生任何事情。

let pc = document.getElementById('pc')
let folder = document.getElementById('folder')
let bin = document.getElementById('bin')
let pcwindow = document.getElementById('pcwindow')
let folderwindow = document.getElementById('folderwindow')
let binwindow = document.getElementById('binwindow')
let pcwindow2 = document.getElementById('pcwindow2')
let folderwindow2 = document.getElementById('folderwindow2')
let folderwindow3 = document.getElementById('folderwindow3')
let binwindow2 = document.getElementById('binwindow2')
let binwindow3 = document.getElementById('binwindow3')
let setting = document.getElementById('setting')
let f2 = document.getElementById('f2')
let f3 = document.getElementById('f3')
let f4 = document.getElementById('f4')
let pic = document.getElementById('pic')
let folder2 = document.getElementById('folder2')
let pcwindow3 = document.getElementById('pcwindow3')
let b1 = document.getElementById('b1')
let b2 = document.getElementById('b2')
let b3 = document.getElementById('b3')
let b4 = document.getElementById('b4')
let b5 = document.getElementById('b5')
let b6 = document.getElementById('b6')
let b7 = document.getElementById('b7')
let b8 = document.getElementById('b8')
let b9 = document.getElementById('b9')

您可以考虑添加一个名为“active”的类，该类的z索引为2，然后向窗口添加一个eventListener，该eventListener将“active”类添加到窗口中。
我制作了一个Fiddle来演示这一点：
在CSS中，我添加了一个名为“active”的类

/* add this class */
.active {
  z-index: 2;
}

然后在JavaScript中，我添加了以下内容：

// this is the portion to make the window active
  newWindow.addEventListener("click", () => {
  if (document.querySelector(".active")) {
    document.querySelector(".active").classList.remove("active");
  }
    newWindow.classList.add("active");
  })
  // end of the portion

每次点击一个窗口，任何现有的“活动”类都会被删除。然后，一个“活动”类会被添加到选中的窗口中。

要动态执行

你可以做的是存储一个名为zIndexCounter的全局变量，在开始时将其设置为0（或者任何其他相关的值），每次创建一个新窗口时，给它分配一个等于这个计数器的z-index，然后递增计数器。
这样就可以确保下一个创建的窗口的z-index总是比前一个窗口的z-index高。

我没有使用z-index，我创建了一个打开窗口的数组，并将单击的窗口移动到数组的末尾，这样它将出现在其他窗口的顶部。然后删除旧窗口，将新窗口数组添加到页面。
您也可以在此处添加zIndex，但不必要。

windows.forEach((elem) => body.appendChild(elem)); // add rearrange windows to page

到

windows.forEach((elem, i) => {
  elem.style.zIndex = i;
  body.appendChild(elem);
}); // add rearrange windows to page

/* also have to add this in double click function */
window.style.zIndex = len();

抱歉我修改了很多地方。
1.在双击打开的每个窗口中添加.new_window类，这样我就可以更容易地选择它们。
1.删除了js/html/css代码中相同的函数、元素和类。
