how to make browser back close magnific-popup - magnific-popup

Question

I have the popup working but sometimes a user clicks the back button on their browser to close the popup.
How can I make the browser back button close a 'magnific-popup' that is already open?
Thanks

Answer 1

After some digging found history.js and then the following
var magnificPopup = null;
jQuery(document).ready(function ($) {
var $img = $(".img-link");
if ($img.length) {
$img.magnificPopup({
type: 'image',
preloader: true,
closeOnContentClick: true,
enableEscapeKey: false,
showCloseBtn: true,
removalDelay: 100,
mainClass: 'mfp-fade',
tClose: '',
callbacks: {
open: function () {
History.Adapter.bind(window, 'statechange', closePopup);
History.pushState({ url: document.location.href }, document.title, "?large");
$(window).on('resize', closePopup);
magnificPopup = this;
},
close: function () {
$(window).unbind('statechange', closePopup)
.off('resize', closePopup);
var State = History.getState();
History.replaceState(null, document.title, State.data["url"]);
magnificPopup = null;
}
}
});
}
});
function closePopup () {
if (magnificPopup != null)
magnificPopup.close();
}

I'm using this solution:
callbacks: {
open: function() {
location.href = location.href.split('#')[0] + "#gal";
}
,close: function() {
if (location.hash) history.go(-1);
}
}
And this code:
$(window).on('hashchange',function() {
if(location.href.indexOf("#gal")<0) {
$.magnificPopup.close();
}
});
So, on gallery open I add #gal hash. When user closes I virtually click back button to remove it. If user clicks back button - everything works fine olso.
This solution does not break back button behavior and does no require any additional plugins.
Comments are welcome.

Just to add to your answer, these are the meaningful lines that I got to work for me.
callbacks:
open: ->
History.pushState({ url: document.location.href }, null, "?dialogOpen")
History.Adapter.bind(window, 'statechange', attemptToCloseDialog)
close: ->
$(window).unbind('statechange', attemptToCloseDialog)
History.replaceState(null, null, History.getState().data['url'])
With attempt being:
attemptToCloseDialog = ->
$.magnificPopup.close() if $.magnificPopup.instance
