javascript - 关闭弹出窗口并打开新窗口

标签 javascript html css popup

我写了一段代码。我有按钮，每个按钮都会打开一个弹出窗口。在打开之前，我希望我的按钮关闭上一个弹出窗口并打开所需的弹出窗口。我正在切换类(class)。因此，我想首先使用 getElementsByClassName() 检查是否有任何可见的弹出窗口，如果有，则将其切换为隐藏。然后使用 getElementById() 将右侧切换为可见。 我的问题是我不知道如何检查 .show 类的可见性，如果在我的 Function2() 中，我首先将按类切换，然后我无法在其后按 id 切换。这是为什么？所以我需要使用 If(the style isvisible in element i ) {then popups[i].classList.toggle("show");} 在此之后我想使用: 

var popup = document.getElementById("myPopup2");
  popup.classList.toggle("show");

但它不起作用。或者有更好的方法来做到这一点？ 

function myFunction2() {

var popups = document.getElementsByClassName('popuptext');
  for(var i = 0; i < 5; i++)
  { 
 popups[i].classList.toggle("show");
 console.log(1);
 
 }
 var popup = document.getElementById("myPopup2");
  popup.classList.toggle("show");
  console.log(2);
 }
 



function myFunction() {
  var popup = document.getElementById("myPopup");
  popup.classList.toggle("show");
  
}
function myFunction3() {
 var popup = document.getElementById("myPopup3");
  popup.classList.toggle("show");
   
}
function myFunction4() {
  var popup = document.getElementById("myPopup4");
  popup.classList.toggle("show");
}
   

 .popup {
      position: absolute;
      display: inline-block;
      cursor: pointer;

最佳答案

我只更新了你的 JS 和一些 HTML。

使代码可重用。可重用的代码就是好代码。当您可以使用一个函数完成所有操作时，不要为每个按钮创建一个函数。

function showPopup(popupID) {
  var popups = document.querySelectorAll(".popuptext");

  for (var i = 0; i < popups.length; i++) {
    popups[i].classList.remove("show");
  }

  var popup = document.getElementById(popupID);
  popup.classList.add("show");
}
.popup {
  position: absolute;
  display: inline-block;
  cursor: pointer;
  -webkit-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: auto;
}


/* POPUPS--------START------------------------------------------------------------------------------------------------------- */

.popup .popuptext {
  visibility: hidden;
  width: 27%;
  height: 93%;
  background-color: #fff;
  color: #004;
  text-align: left;
  border-radius: 0px;
  padding: 10px;
  position: fixed;
  top: 48%;
  left: 20%;
  transform: translate(-50%, -50%);
  margin-left: -80px;
  border-left: 75px solid white;
  overflow: auto;
  border-right: 10px solid white;
  border-bottom: 35px solid white;
  z-index: 10;
  border-top: 35px solid white;
  box-shadow: inset 0 0 0 rgba(255, 255, 255, 0.5), 2px 20px 2px rgba(0, 0, 0, 0.19);
}


/* POPUPS----------------END------------------------------------------------------------------------------------------ */


/* Toggle this class - hide and show the popup */

.popup .show {
  visibility: visible;
  -webkit-animation: fadeIn 1s;
  animation: fadeIn 1s;
  animation: move 1s;
}


/* Add animation (fade in the popup) */

@-webkit-keyframes fadeIn {
  from {
    opacity: 0;
  }
  to {
    opacity: 1;
  }
}

@keyframes fadeIn {
  from {
    opacity: 0;
  }
  to {
    opacity: 1;
  }
}

@keyframes move {
  from {
    left: 0%;
  }
  to {
    top: 48%;
  }
}

@-webkit-keyframes move {
  from {
    left: 0%;
  }
  to {
    top: 48%;
  }
}
