javascript 为什么我的多个下拉菜单不工作？

我正在尝试使用下面的代码创建两个下拉菜单
myFunction（）的第一个按钮工作正常，但第二个my（）只有在我单击按钮时才工作，我想让它在窗口的任何地方单击时都有响应
我试着用eventlistener制作手柄，让window.onclick和两个按钮一起工作

function myFunction() {
  document.getElementById("myDropdown").classList.toggle("show");
}

function my() {
  document.getElementById("myaccountDropdown").classList.toggle("showed");
}
// Function to handle clicks on the window
function handleClick(event) {
  // Check if the click target is NOT the "dropbtn" element
  if (!event.target.matches(".dropbtn")) {
    // Get references to all the dropdown-content elements
    var dropdowns = document.getElementsByClassName("dropdown-content");
    // Loop through the dropdown-content elements
    for (var i = 0; i < dropdowns.length; i++) {
      var openDropdown = dropdowns[i];
      // Check if the current dropdown-content element has the "show" class
      if (openDropdown.classList.contains("show")) {
        // If it does, remove the "show" class to close the dropdown
        openDropdown.classList.remove("show");
      }
    }
  }

  // Check if the click target is the "clicked" element
  if (event.target.matches(".clicked")) {
    // Get references to all the dropdown-accountsettings elements
    var dropdowns = document.getElementsByClassName("dropdown-accountsetting");
    // Loop through the dropdown-accountsettings elements
    for (var i = 0; i < dropdowns.length; i++) {
      var openDropdown = dropdowns[i];
      // Check if the current dropdown-accountsettings element has the "showed" class
      if (openDropdown.classList.contains("showed")) {
        // If it does, remove the "showed" class to close the dropdown
        openDropdown.classList.remove("showed");
      }
    }
  }
}

// Add the event listener to the window
window.addEventListener("click", handleClick);

/* Dropdown Button */

.dropbtn {
  color: whitesmoke;
  width: 100%;
  height: 100%;
  display: flex;
  align-content: stretch;
  justify-content: center;
  align-items: center;
  flex-wrap: inherit;
  cursor: pointer;
}

.dropbtn:hover {
  color: blueviolet;
}

/* The container <div> - needed to position the dropdown content */

.dropdown {
  position: relative;
  top: 8px;
}

/* Dropdown Content (Hidden by Default) */

.dropdown-content {
  display: none;
  position: absolute;
  background-color: #242222;
  min-width: 160px;
  box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
  z-index: 1;

/* Links inside the dropdown */

.dropdown-content a {
  color: rgb(255, 255, 255);
  padding: 12px 16px;
  text-decoration: none;
  display: block;
}

/* Change color of dropdown links on hover */

.dropdown-content a:hover {
  background-color: #ddd;
}

/* Show the dropdown menu (use JS to add this class to the .dropdown-content container when the user clicks on the dropdown button) */

.show {
  display: block;
}

.dropbtn .fa {
  position: relative;
  right: -3px;
}

/*  account logo setting */

.clicked {
  color: whitesmoke;
  width: 100%;
  height: 100%;

.dropdown-accountsetting a:hover {
  background-color: #ddd;
}

.showed {
  display: block;
}

<li>
  <p onclick="myFunction()" class="dropbtn">
    Categories
    <i class="fa fa-caret-down icon" aria-hidden="true"> </i>
  </p>
  <div id="myDropdown" class="dropdown-content">
    <a href="#">Link 1</a>
    <a href="#">Link 2</a>
    <a href="#">Link 3</a>
  </div>
</li>

<div class="account-logo">
  <p onclick="my()" class="dropbtn">
    <i class="fa fa-user" aria-hidden="true"></i
            ><i class="fa fa-caret-down" aria-hidden="true"></i>
  </p>
  <div id="myaccountDropdown" class="dropdown-accountsetting">
    <a href="#">Linked 1</a>

    <a href="#">Link 3</a>
  </div>
</div>

看起来你的第二个下拉菜单的问题是，它只在你点击按钮本身时切换，而不是当你点击窗口上的任何其他地方。
要解决这个问题，您可以修改事件侦听器以检查两个下拉菜单，并相应地删除相应的类。以下是修改后的事件侦听器函数代码：

function handleClick(event) {
  // Check if the click target is NOT the "dropbtn" element or the "clicked" element
  if (!event.target.matches(".dropbtn") && !event.target.matches(".clicked")) {
    // Get references to all the dropdown-content and dropdown-accountsetting elements
    var dropdowns = document.getElementsByClassName("dropdown-content");
    var accountDropdowns = document.getElementsByClassName("dropdown-accountsetting");
    // Loop through the dropdown-content elements
    for (var i = 0; i < dropdowns.length; i++) {
      var openDropdown = dropdowns[i];
      // Check if the current dropdown-content element has the "show" class
      if (openDropdown.classList.contains("show")) {
        // If it does, remove the "show" class to close the dropdown
        openDropdown.classList.remove("show");
      }
    }
    // Loop through the dropdown-accountsetting elements
    for (var j = 0; j < accountDropdowns.length; j++) {
      var openAccountDropdown = accountDropdowns[j];
      // Check if the current dropdown-accountsetting element has the "showed" class
      if (openAccountDropdown.classList.contains("showed")) {
        // If it does, remove the "showed" class to close the dropdown
        openAccountDropdown.classList.remove("showed");
      }
    }
  }

  // Check if the click target is the "dropbtn" element
  if (event.target.matches(".dropbtn")) {
    document.getElementById("myDropdown").classList.toggle("show");
  }

  // Check if the click target is the "clicked" element
  if (event.target.matches(".clicked")) {
    document.getElementById("myaccountDropdown").classList.toggle("showed");
  }
}

// Add the event listener to the window
window.addEventListener("click", handleClick);
