Popper.js: How to close popup when clicking outside

Question

I'm using Popper.js to show a popup elment having the class .js-share-cf-popover when clicking elements with class .js-share-cf-btn.

But I want the popup to close only when I click outside of it. Here my actual code that show the popup:

var reference = $('.js-share-cf-btn');
var popover = $('.js-share-cf-popover');
popover.hide();

$(document).on('click', reference, function(e) {
  e.preventDefault();

  popover.show();

  var popper = new Popper(reference, popover, {
    placement: 'top',
  });
});

I found something here but I can't get it works

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();
    }
  });

});

For those using React, I created a gist of an HOC that you can attach to any component to close it when clicked outside:

I found a really simple solution to this.

jQuery version

<div class="Popper">
    <div class="stopPropagation">
        <p>Clicking on me won't close the Popper</p>
    </div>
</div>

$('.stopPropagation').on('click touchend', function(e) {
    e.stopPropagation()
})

Since the click event does not propagate up to the Popper, the Popper will not closed when clicked.

React version

<Popper>
    {/* eslint-disable-next-line jsx-a11y/click-events-have-key-events */}
    <div onClick={e => e.stopPropagation()} role="none">
        <p>Clicking on me won't close the Popper</p>
    </div>
</Popper>
