如何使关闭按钮在我的模态上工作

Question

我有 3 个全屏模态，它们打开得非常好，我只需要能够使用其中带有 × 的跨度关闭它们，我似乎无法在单击十字时关闭模态。

我尝试使用以下方法但它似乎不起作用，即使类似的代码适用于在模态窗口之外单击（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";
  })

代码的所有其他部分也可以更简单。 像那样：

 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; }
