JavascriptJqueryPopupJavascript Problem Overview
The question is pretty much all in the title.
Is it possible (and how?) to open a popup with javascript and then detect when the user closes it?
I am using jquery within the project so a jquery solution would be good. Cheers!
Javascript Solutions
Solution 1 - Javascript
If you have control over the contents of the pop-up, handle the window's unload
event there and notify the original window via the opener
property, checking first whether the opener has been closed. Note this won't always work in Opera.
window.onunload = function() {
var win = window.opener;
if (!win.closed) {
win.someFunctionToCallWhenPopUpCloses();
}
};
Since the unload
event will fire whenever the user navigates away from the page in the pop-up and not just when the window is closed, you should check that the pop-up has actually closed in someFunctionToCallWhenPopUpCloses
:
var popUp = window.open("popup.html", "thePopUp", "");
function someFunctionToCallWhenPopUpCloses() {
window.setTimeout(function() {
if (popUp.closed) {
alert("Pop-up definitely closed");
}
}, 1);
}
If you don't have control over the contents of the pop-up, or if one of your target browsers does not support the unload
event, you're reduced to some kind of polling solution in the main window. Adjust interval to suit.
var win = window.open("popup.html", "thePopUp", "");
var pollTimer = window.setInterval(function() {
if (win.closed !== false) { // !== is required for compatibility with Opera
window.clearInterval(pollTimer);
someFunctionToCallWhenPopUpCloses();
}
}, 200);
Solution 2 - Javascript
There is a very simple solution to your problem.
First make a new object which will open up a pop like this :
var winObj = window.open('http://www.google.com','google','width=800,height=600,status=0,toolbar=0');
In order to know when this popup window is closed, you just have to keep checking this with a loop like the following :
var loop = setInterval(function() {
if(winObj.closed) {
clearInterval(loop);
alert('closed');
}
}, 1000);
Now you can replace alert with any javascript code you want.
Have Fun! :)

Try looking into the unload
and beforeunload
window events. Monitoring these should give you an opportunity to call back when the DOM unloads when the window is closed via something like this:
var newWin = window.open('/some/url');
newWin.onunload = function(){
// DOM unloaded, so the window is likely closed.
}
Solution 4 - Javascript
If you can use the jQuery UI Dialog, it actually has a close
event.
Solution 5 - Javascript
To open a new window call:
var wnd = window.open("file.html", "youruniqueid", "width=400, height=300");
If you just want to know when that window is going to close, use onunload
.
wnd.onunload = function(){
// do something
};
If you want a confirmation from the user before the can close it, use onbeforeunload
.
wnd.onbeforeunload = function(){
return "are you sure?";
};
Solution 6 - Javascript
We do this in one of my projects at work.
The trick is to have a JS function in your parent page that you plan to call when the popup is closed, then hook the unload event in the popup.
The window.opener
property refers to the page that spawned this popup.
For example, if I wrote a function named callingPageFunction
on my original page, I would call it from the popup like this:
$(window).unload(function() {
window.opener.callingPageFunction()
});
Two notes:
- This should be wrapped in a ready function.
- I have an anonymous function because you may want other logic in there
Solution 7 - Javascript
I thinks best way is:
const popup = this.window.open(url.toString());
popup.addEventListener('unload', ()=> console.log('closed'))
Solution 8 - Javascript
Yes, handle the onbeforeUnload event for the popup window and then call a function on the parent window using:
window.opener.myFunction()
