Popper.js: How to close popup when clicking outside
For those using React, I created a gist of an HOC that you can attach to any component to close it when clicked outside:
https://gist.github.com/elie222/850bc4adede99650508aba2090cd5da1
You can achieve this, by removing event delegation and checking the target on event click by using the .is(), (compare e.target if it equals to the referencing button, otherwise hide the popup)
See fiddle
Added snippet as your code :
also made change in the Popper instance you should pass the current click js-share-cf-btn so the $(e.target) element
$(function() {
var reference = $('.js-share-cf-btn');
var popover = $('.js-share-cf-popover');
popover.hide();
$(document).on('click touchend', function(e) {
var target = $(e.target);
// ne need to reshow and recreate popper when click over popup so return;
if(target.is(popover)) return;
if (target.is(reference)) {
e.preventDefault();
popover.show();
var popper = new Popper(target, popover, {
placement: 'top',
});
}else {
popover.hide();
}
});
});body {
background: #20262E;
padding: 20px;
font-family: Helvetica;
}
.section {
background: #fff;
padding: 20px;
font-size: 25px;
text-align: center;
transition: all 0.2s;
margin: 0 auto;
width: 300px;
margin-bottom: 20px;
}
.share-popover {
background: red;
color: white;
padding: 10px;

<div class="section">
<p>Section 1</p>
<a href="#" class="js-share-cf-btn">This is the trigger</a>
</div>
<div class="section">
<p>Section 2</p>
<a href="#" class="js-share-cf-btn">This is the trigger</a>
</div>
<div class="section">
<p>Section 3</p>
<a href="#" class="js-share-cf-btn">This is the trigger</a>
</div>
<div class="share-popover js-share-cf-popover">
This is the popup
</div>Something like this should do the trick (by checking the target when you are clicking somewhere):
$(function() {
var ref = $('.js-share-cf-btn');
var popover = $('.js-share-cf-popover');
popover.hide();
$(document).on('click', function(e) {
var target = $(e.target);
if (target.is(ref) || target.is(popover) ) {
e.preventDefault();
popover.show();
var popper = new Popper(ref, popover, {
placement: 'right',
});
}else {
popover.hide();
}
});
});
