如何使关闭按钮在我的调制解调器上工作？

Question

我有三个全屏幕模式，打开的非常好，我只需要能够关闭他们使用的跨度，其中有一个×，我似乎不能得到模态关闭时，点击十字。

我尝试过使用以下方法，但它似乎不起作用，即使类似的代码可以用于单击模态窗口之外(当它们不是全屏时)。

span.onclick = function(event) {
  if (
   event.target.id == modal1.id ||
   event.target.id == modal2.id ||
   event.target.id == modal3.id
  ) {
    document.getElementById(event.target.id).style.display = "none";
  }
}

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");

var span = document.getElementsByClassName("close1");

btn1.onclick = function() {
  modal1.style.display = "block";
}
btn2.onclick = function() {
  modal2.style.display = "block";
}
btn3.onclick = function() {
  modal3.style.display = "block";
}

span.onclick = function() {
  modal1.style.display = "none";
}

Answer 1

简单地说：

document.querySelectorAll('span.close').forEach(sp=>
  {
  sp.onclick=()=> sp.parentNode.parentNode.style.display = "none";
  })

代码的其他部分也可以更简单。就像这样：

​

document.querySelectorAll('div.bt4modal').forEach(dv=>
  {
  dv.onclick=()=> document.getElementById(dv.dataset.modalId).style.display = "block";
  })
document.querySelectorAll('span.close').forEach(sp=>
  {
  sp.onclick=()=> sp.parentNode.parentNode.style.display = "none";
  })

.modals {
  display: none; /* Hidden by default */
  position: fixed; /* Stay in place */
  z-index: 1; /* Sit on top */
  left: 0;
  top: 0;
  width: 100%; /* Full width */
  height: 100%; /* Full height */
  overflow: auto; /* Enable scroll if needed */
  background-color: rgb(0,0,0); /* Fallback color */
  background-color: rgba(0,0,0,0.4); /* Black w/ opacity */
}
/* Modal Content/Box */
.modal-content {
  background-color: #131B1D;
  margin: 0 auto;
  text-align: center;
  padding: 20px;
  border: 1px solid #888;
  width: 100vw;
  height: 100vh;
}
.modal-content .close {
  color: #fff;
  float: right;
  font-size: 10rem;
}
.modal-content img {
  margin: 0 auto;
  margin-top: 15rem;
  text-align: center;
}
.bt4modal >img {
  height: 400px;
}
.modal-content >img {
  height: 800px;
}
