Close Popup By Clicking Outside It Javascript

I used this tutorial to add popups to my webpage. Is there a way to make it so a popup closes when you click outside it/click on a different one. I've tried adding an invisibleDiv

Solution 1:

Having a global click-handler that checks the clicked element's classList is one way to close the pop-up when clicking outside of it. Here is an example:

const popups = [...document.getElementsByClassName('popup')];

window.addEventListener('click', ({ target }) => {
  const popup = target.closest('.popup');
  const clickedOnClosedPopup = popup && !popup.classList.contains('show');
  
  popups.forEach(p => p.classList.remove('show'));
  
  if (clickedOnClosedPopup) popup.classList.add('show');  
});

/* Popup container - can be anything you want */.popup {
  position: relative;
  display: inline-block;
  cursor: pointer;
  -webkit-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;
}

/* The actual popup */.popup.popuptext {
  visibility: hidden;
  width: 160px;
  background-color: #555;
  color: #fff;
  text-align: center;
  border-radius: 6px;
  padding: 8px0;
  position: absolute;
  z-index: 1;
  bottom: 125%;
  left: 50%;
  margin-left: -80px;
}

/* Popup arrow */.popup.popuptext::after {
  content: "";
  position: absolute;
  top: 100%;
  left: 50%;
  margin-left: -5px;
  border-width: 5px;
  border-style: solid;
  border-color: #555 transparent transparent transparent;
}

/* Toggle this class - hide and show the popup */.popup.show.popuptext {
  visibility: visible;
  -webkit-animation: fadeIn 1s;
  animation: fadeIn 1s;
}

/* Add animation (fade in the popup) */@-webkit-keyframes fadeIn {
  from {opacity: 0;} 
  to {opacity: 1;}
}

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

<h2>Popup</h2><divclass="popup">Click me to toggle the popup!
  <spanclass="popuptext">A Simple Popup!</span></div><divclass="popup">Click me to toggle the popup!
  <spanclass="popuptext">A Simple Popup!</span></div>

Solution 2:

Add an onclick to the popup's container and stop event propagation on all internal elements you don't want to trigger the action.

let popup = document.querySelector(".popup");

functiontoggle(e) {
  e.stopPropagation();
  popup.classList.toggle("hide");
}

functionclosePopup() {

  if (!popup.classList.contains("hide")) {
    popup.classList.toggle("hide");
  }
}

body {
  margin: 0;
}

.container {
  width: 100vw;
  height: 100vh;
  background: lightgray;
  display: flex;
  flex-direction: column;
  justify-content: center;
}

.popup {
  width: 100px;
  height: 100px;
  background: white;
  margin: 0 auto;
}

button {
  position: fixed;
  top: 0;
}

.hide {
  display: none;
}

<divclass="container"onclick="closePopup()"><divclass="popup hide"onclick="event.stopPropagation()"></div><Buttononclick="toggle(event)">Toggle</Button></div>
