javascript - 多个模态只能关闭1个

Question

我已经成功在我的网站上创建了多个模态，但是我只能关闭三个模态中的最后一个，即使它们具有 3 个独立的函数和 3 个不同的类。

如何才能使每个模式都通过相应的按钮打开，并在您单击模式窗口外时关闭。

HTML

<div class="container flex bg-black-opacity mt-40 rounded pt-10 pb-12 mb-10 mx-auto items-center">
        <div class="container ml-5 cursor-pointer" id='1btn'>
            <img src="assets/img/merch-1.png" alt="" style='height: 400px;' class='shadow-pink'>
            <p class='uppercase mt-4 text-white'>Vice Versa 2020 Heather Grey Sweatshirt</p>
            <p class="text-white mt-4 ml-1 text-2xl">£15.00</p>

        </div>
        <div id="1mdl" class="modal1">

            <!-- Modal content -->
            <div class="modal-content">
              <p>Some text in the Modal..</p>
            </div>
        </div>
        <div class="container ml-5 cursor-pointer" id='2btn'>
            <img src="assets/img/merch-2.png" alt="" style='height: 400px;' class='shadow-pink'>

            </div>
        </div>

    </div>

JavaScript

var modal1 = document.getElementById("1mdl");
var modal2 = document.getElementById("2mdl");
var modal3 = document.getElementById("3mdl");

var btn1 = document.getElementById("1btn");
var btn2 = document.getElementById("2btn");
var btn3 = document.getElementById("3btn");

btn1.onclick = function() {
  modal1.style.display = "block";
}
btn2.onclick = function() {
  modal2.style.display = "block";
}
btn3.onclick = function() {
  modal3.style.display = "block";
}
window.onclick = function(event) {
  if (event.target == modal1) {
    modal1.style.display = "none";
  }
} 
window.onclick = function(event) {
  if (event.target == modal2) {
    modal2.style.display = "none";
  }
} 
window.onclick = function(event) {
  if (event.target == modal3) {
    modal3.style.display = "none";
  }
}

重新分配点击事件会覆盖之前绑定(bind)的回调函数

只需使用它(保持原始问题中的简化)

 window.onclick = function(event) {
    if (event.target == modal1) {
        modal1.style.display = "none";
    } else if (event.target == modal2) {
        modal2.style.display = "none";
    } else
    if (event.target == modal3) {
        modal3.style.display = "none";
    }
}
