window.closed IE9 reporting true when window is still open - javascript

UPDATE 2012-01-10
the popup URL is in another domain as the parent window, which appears to be the issue! How can I solve it?
I'm using the following code to detect whether the popup window is closed. It works fine in Firefox 8 and Chrome but doesn't function as expected in IE9. In IE9 the alert with "true" shows already when the popup is still open. How come IE9 has a reference to the window and the closed property reports true when the window is still open? And how can I fix it?
Javascript
var dialogWindow;
var dialogTimer;
function openDialog(url, name, options) {
dialogWindow = window.open(url, name, options);
dialogTimer = setInterval(function() {
if(dialogWindow.closed) // IE9 reports true and executes function
{
alert(dialogWindow.closed); // alert with "true"
clearInterval(dialogTimer);
window.location.reload();
}
}, 2500);
if (dialogWindow && dialogWindow.focus)
dialogWindow.focus();
}
UPDATE
I also tried the following approach, which shows the exact same behaviour in IE9
var dialogWindow;
var dialogTimer;
function openDialog(url, name, options)
{
dialogWindow = window.open(url, name, options);
dialogTimer = setInterval("checkDialogOpen()", 2500);
if (dialogWindow && dialogWindow.focus)
dialogWindow.focus();
}
function checkDialogOpen()
{
if(dialogWindow.closed)
{
alert(dialogWindow.closed);
clearInterval(dialogTimer);
window.location.reload();
}
}

From what I can tell, this is a bug in IE9.

you have an issue with your script
Change:
dialogTimer = setInterval(function()
{
if(dialogWindow.closed) // IE9 reports true and executes function
{
to
dialogTimer = setInterval(function()
{
var dialogClosedStatus = dialogWindow.closed;
if(dialogClosedStatus) // IE9 reports true and executes function
{
EDIT: My typing was bogus:fixed
Test page: http://jsfiddle.net/MarkSchultheiss/k2jHS/
special note: the popup will keep appearing due to your window reload in my test page example.
NOTE: if that does not do the trick, try setting the variable to null as this example:

window.closed() is true when console debugger is closed, but false when console debugger is open IE behaviour

windowobj.closed() is coming true always when console debugger is closed in IE browser.
windowobj = window.open(
url,
"_blank",
"resizable=yes,width=1024,height=630,top=0,left=0,status=1"
);
if (!windowobj.closed) {
var timer = setInterval(checkChild, 500);
}
It seems that the value of window.closed won't have any difference no matter the console is open or not. If you want to check if the window is closed, you should modify your code like this:
windowobj = window.open(
url,
"_blank",
"resizable=yes,width=1024,height=630,top=0,left=0,status=1"
);
setInterval(function () {
if (!windowobj.closed) {
checkChild
}
}, 500);
You could also refer to this article and try this demo in IE, the test result won't be changed no matter the console is open or close.

How to get Chrome to throw exception when changing url if it fails

I have a reference to a new window opened with js
var theNewTab="";
theNewTab = window.open(theURL, 'winRef');
then I change the url in the as the user clicks on another link in the parent window using
theNewTab.location.href = targetLink;
theNewTab.focus();
The problem i'm having with chrome that id doesn't throw exception if the the window doesn't exist anymore "closed" unlink FF & IE which im using to open the window again.
try {
theNewTab.location.href = targetLink;
theNewTab.focus();
}catch(err) {
theNewTab = window.open(theURL, 'winRef');
theNewTab.focus();
}
PS: I tried to use "window.open" every time but if the window already open, id does not reload the page or it does but it doesn't re-execute the script I have in document ready I think.
I'm not sure what you need.
<script type="text/javascript">
var theNewTab = null;
function openNewTab(theURL) {
if (theNewTab == null || theNewTab.closed == true) {
theNewTab = window.open(theURL);
} else {
theNewTab.location.href = theURL;
}
theNewTab.focus();
};
// use the function when you need it
$('a').click(function() {
openNewTab($(this).attr('href'));
});
</script>
Is this example helpful for you?

change on the javascript function is not being reflected in the browser

I've difficult closing popup. window.close(); is working only with Chrome not IE. After doing some researches, I found this article which tells why I shouldn't use window.close() directly in the popup to close it.
//Global var to store a reference to the opened window
var openedWindow;
function openWindow() {
openedWindow = window.open('moreinfo.htm');
}
function closeOpenedWindow() {
openedWindow.close();
}
function myReload() {
location.reload();
}
The problem is that the first time I wrote the closeOpenWindow method, I forgot to put the () at the end, so it was openedWindow.close;
I've fixed the problem, but I'm still getting the same error on that line.
openedWindow.close is not a function
If I delete the the entire function closeOpenedWindow(), I get the error that closeOpenedWindow() is not a function. When I put it back, I get the previous error that openedWindow.close is not a function.
Thanks for helping
EDIT:
This is how I'm calling the function from the popupu:
function mycloseChild() {
window.opener.myReload();
window.opener.closeOpenedWindow();
}
var openedWindow = {
open: () => { window.open('moreinfo.htm') },
close: () => { window.close() }
}
Actually, this seems to work in Chrome Debugger. Maybe a timing issue?
//Global var to store a reference to the opened window
var openedWindow;
function openWindow() {
openedWindow = window.open('moreinfo.htm');
}
function closeOpenedWindow() {
openedWindow.close();
}
openWindow();
//openedWindow is new window
closeOpenedWindow();
//openedWindow closes
It looks like you can use window.opener from the openedWindow to get a reference to the original window object which has the method closeOpenedWindow. but in order for that to work, you need to add closeOpenedWindow to the original window like so
window['closeOpenedWindow'] = function() {
openedWindow.close();
}
and then call it from the opened window like so window.opener.closeOpenedWindow()

function Window.focus doesn't work in IE (8, 9, 10, 11)

Here is my code, and this code to open new tab and focus on it.
If tab is not opened yet, I will open it with specify name.
If tab is opened, I will focus on it by using window.focus();
Quick test: http://jsfiddle.net/u2jd2oLw/1/
Javascript Code
var tabs = [];
$('#btnOpenTab').on('click', function(){
openTab('http://google.com.vn', 'GG');
});
function openTab(url, tabNm) {
try {
if (tabs[tabNm]) {
tabs[tabNm].focus();
} else {
var mTab = window.open(url, tabNm);
tabs[tabNm] = mTab;
tabs[tabNm].focus();
}
} catch(e) {
alert(e.message);
}
}
HTML Code
<button id="btnOpenTab">Open Tab</button>
Actually, I check in IE11, it occurred that "Access is denied"
And I tried to turn off option: "Turn on Pop-up Blocker" by un-check CheckBox.
Do you have any suggestion?
Thanks!!

How to check Popup blocker enabled Without loading popup window in chrome using Javascript [duplicate]

I am aware of javascript techniques to detect whether a popup is blocked in other browsers (as described in the answer to this question). Here's the basic test:
var newWin = window.open(url);
if(!newWin || newWin.closed || typeof newWin.closed=='undefined')
{
//POPUP BLOCKED
}
But this does not work in Chrome. The "POPUP BLOCKED" section is never reached when the popup is blocked.
Of course, the test is working to an extent since Chrome doesn't actually block the popup, but opens it in a tiny minimized window at the lower right corner which lists "blocked" popups.
What I would like to do is be able to tell if the popup was blocked by Chrome's popup blocker. I try to avoid browser sniffing in favor of feature detection. Is there a way to do this without browser sniffing?
Edit: I have now tried making use of newWin.outerHeight, newWin.left, and other similar properties to accomplish this. Google Chrome returns all position and height values as 0 when the popup is blocked.
Unfortunately, it also returns the same values even if the popup is actually opened for an unknown amount of time. After some magical period (a couple of seconds in my testing), the location and size information is returned as the correct values. In other words, I'm still no closer to figuring this out. Any help would be appreciated.
Well the "magical time" you speak of is probably when the popup's DOM has been loaded. Or else it might be when everything (images, outboard CSS, etc.) has been loaded. You could test this easily by adding a very large graphic to the popup (clear your cache first!). If you were using a Javascript Framework like jQuery (or something similar), you could use the ready() event (or something similar) to wait for the DOM to load before checking the window offset. The danger in this is that Safari detection works in a conflicting way: the popup's DOM will never be ready() in Safari because it'll give you a valid handle for the window you're trying to open -- whether it actually opens or not. (in fact, i believe your popup test code above won't work for safari.)
I think the best thing you can do is wrap your test in a setTimeout() and give the popup 3-5 seconds to complete loading before running the test. It's not perfect, but it should work at least 95% of the time.
Here's the code I use for cross-browser detection, without the Chrome part.
function _hasPopupBlocker(poppedWindow) {
var result = false;
try {
if (typeof poppedWindow == 'undefined') {
// Safari with popup blocker... leaves the popup window handle undefined
result = true;
}
else if (poppedWindow && poppedWindow.closed) {
// This happens if the user opens and closes the client window...
// Confusing because the handle is still available, but it's in a "closed" state.
// We're not saying that the window is not being blocked, we're just saying
// that the window has been closed before the test could be run.
result = false;
}
else if (poppedWindow && poppedWindow.test) {
// This is the actual test. The client window should be fine.
result = false;
}
else {
// Else we'll assume the window is not OK
result = true;
}
} catch (err) {
//if (console) {
// console.warn("Could not access popup window", err);
//}
}
return result;
}
What I do is run this test from the parent and wrap it in a setTimeout(), giving the child window 3-5 seconds to load. In the child window, you need to add a test function:
function test() {}
The popup blocker detector tests to see whether the "test" function exists as a member of the child window.
ADDED JUNE 15 2015:
I think the modern way to handle this would be to use window.postMessage() to have the child notify the parent that the window has been loaded. The approach is similar (child tells parent it's loaded), but the means of communication has improved. I was able to do this cross-domain from the child:
$(window).load(function() {
this.opener.postMessage({'loaded': true}, "*");
this.close();
});
The parent listens for this message using:
$(window).on('message', function(event) {
alert(event.originalEvent.data.loaded)
});
Hope this helps.
Just one improvement to InvisibleBacon's snipet (tested in IE9, Safari 5, Chrome 9 and FF 3.6):
var myPopup = window.open("popupcheck.htm", "", "directories=no,height=150,width=150,menubar=no,resizable=no,scrollbars=no,status=no,titlebar=no,top=0,location=no");
if (!myPopup)
alert("failed for most browsers");
else {
myPopup.onload = function() {
setTimeout(function() {
if (myPopup.screenX === 0) {
alert("failed for chrome");
} else {
// close the test window if popups are allowed.
myPopup.close();
}
}, 0);
};
}
The following is a jQuery solution to popup blocker checking. It has been tested in FF (v11), Safari (v6), Chrome (v23.0.127.95) & IE (v7 & v9). Update the _displayError function to handle the error message as you see fit.
var popupBlockerChecker = {
check: function(popup_window){
var _scope = this;
if (popup_window) {
if(/chrome/.test(navigator.userAgent.toLowerCase())){
setTimeout(function () {
_scope._is_popup_blocked(_scope, popup_window);
},200);
}else{
popup_window.onload = function () {
_scope._is_popup_blocked(_scope, popup_window);
};
}
}else{
_scope._displayError();
}
},
_is_popup_blocked: function(scope, popup_window){
if ((popup_window.innerHeight > 0)==false){ scope._displayError(); }
},
_displayError: function(){
alert("Popup Blocker is enabled! Please add this site to your exception list.");
}
};
Usage:
var popup = window.open("http://www.google.ca", '_blank');
popupBlockerChecker.check(popup);
Hope this helps! :)
Rich's answer isn't going to work anymore for Chrome. Looks like Chrome actually executes any Javascript in the popup window now. I ended up checking for a screenX value of 0 to check for blocked popups. I also think I found a way to guarantee that this property is final before checking. This only works for popups on your domain, but you can add an onload handler like this:
var myPopup = window.open("site-on-my-domain", "screenX=100");
if (!myPopup)
alert("failed for most browsers");
else {
myPopup.onload = function() {
setTimeout(function() {
if (myPopup.screenX === 0)
alert("failed for chrome");
}, 0);
};
}
As many have reported, the "screenX" property sometimes reports non-zero for failed popups, even after onload. I experienced this behavior as well, but if you add the check after a zero ms timeout, the screenX property always seems to output a consistent value.
Let me know if there are ways to make this script more robust. Seems to work for my purposes though.
This worked for me:
cope.PopupTest.params = 'height=1,width=1,left=-100,top=-100,location=no,toolbar=no,menubar=no,scrollbars=no,resizable=no,directories=no,status=no';
cope.PopupTest.testWindow = window.open("popupTest.htm", "popupTest", cope.PopupTest.params);
if( !cope.PopupTest.testWindow
|| cope.PopupTest.testWindow.closed
|| (typeof cope.PopupTest.testWindow.closed=='undefined')
|| cope.PopupTest.testWindow.outerHeight == 0
|| cope.PopupTest.testWindow.outerWidth == 0
) {
// pop-ups ARE blocked
document.location.href = 'popupsBlocked.htm';
}
else {
// pop-ups are NOT blocked
cope.PopupTest.testWindow.close();
}
The outerHeight and outerWidth are for chrome because the 'about:blank' trick from above doesn't work in chrome anymore.
I'm going to just copy/paste the answer provided here: https://stackoverflow.com/a/27725432/892099 by DanielB . works on chrome 40 and it's very clean. no dirty hacks or waiting involves.
function popup(urlToOpen) {
var popup_window=window.open(urlToOpen,"myWindow","toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=yes, resizable=yes, copyhistory=yes, width=400, height=400");
try {
popup_window.focus();
}
catch (e) {
alert("Pop-up Blocker is enabled! Please add this site to your exception list.");
}
}
How about a Promise approach ?
const openPopUp = (...args) => new Promise(s => {
const win = window.open(...args)
if (!win || win.closed) return s()
setTimeout(() => (win.innerHeight > 0 && !win.closed) ? s(win) : s(), 200)
})
And you can use it like the classic window.open
const win = await openPopUp('popuptest.htm', 'popuptest')
if (!win) {
// popup closed or blocked, handle alternative case
}
You could change the code so that it fail the promise instead of returning undefined, I just thought that if was an easier control flow than try / catch for this case.
Check the position of the window relative to the parent. Chrome makes the window appear almost off-screen.
I had a similar problem with popups not opening in Chrome. I was frustrated because I wasn't trying to do something sneaky, like an onload popup, just opening a window when the user clicked. I was DOUBLY frustrated because running my function which included the window.open() from the firebug command line worked, while actually clicking on my link didn't! Here was my solution:
Wrong way: running window.open() from an event listener (in my case, dojo.connect to the onclick event method of a DOM node).
dojo.connect(myNode, "onclick", function() {
window.open();
}
Right way: assigning a function to the onclick property of the node that called window.open().
myNode.onclick = function() {
window.open();
}
And, of course, I can still do event listeners for that same onclick event if I need to. With this change, I could open my windows even though Chrome was set to "Do not allow any site to show pop-ups". Joy.
If anyone wise in the ways of Chrome can tell the rest of us why it makes a difference, I'd love to hear it, although I suspect it's just an attempt to shut the door on malicious programmatic popups.
Here's a version that is currently working in Chrome. Just a small alteration away from Rich's solution, though I added in a wrapper that handles the timing too.
function checkPopupBlocked(poppedWindow) {
setTimeout(function(){doCheckPopupBlocked(poppedWindow);}, 5000);
}
function doCheckPopupBlocked(poppedWindow) {
var result = false;
try {
if (typeof poppedWindow == 'undefined') {
// Safari with popup blocker... leaves the popup window handle undefined
result = true;
}
else if (poppedWindow && poppedWindow.closed) {
// This happens if the user opens and closes the client window...
// Confusing because the handle is still available, but it's in a "closed" state.
// We're not saying that the window is not being blocked, we're just saying
// that the window has been closed before the test could be run.
result = false;
}
else if (poppedWindow && poppedWindow.outerWidth == 0) {
// This is usually Chrome's doing. The outerWidth (and most other size/location info)
// will be left at 0, EVEN THOUGH the contents of the popup will exist (including the
// test function we check for next). The outerWidth starts as 0, so a sufficient delay
// after attempting to pop is needed.
result = true;
}
else if (poppedWindow && poppedWindow.test) {
// This is the actual test. The client window should be fine.
result = false;
}
else {
// Else we'll assume the window is not OK
result = true;
}
} catch (err) {
//if (console) {
// console.warn("Could not access popup window", err);
//}
}
if(result)
alert("The popup was blocked. You must allow popups to use this site.");
}
To use it just do this:
var popup=window.open('location',etc...);
checkPopupBlocked(popup);
If the popup get's blocked, the alert message will display after the 5 second grace period (you can adjust that, but 5 seconds should be quite safe).

Wow there sure are a lot of solutions here. This is mine, it uses solutions taken from the current accepted answer (which doesn't work in latest Chrome and requires wrapping it in a timeout), as well as a related solution on this thread (which is actually vanilla JS, not jQuery).
Mine uses a callback architecture which will be sent true when the popup is blocked and false otherwise.
window.isPopupBlocked = function(popup_window, cb)
{
var CHROME_CHECK_TIME = 2000; // the only way to detect this in Chrome is to wait a bit and see if the window is present
function _is_popup_blocked(popup)
{
return !popup.innerHeight;
}
if (popup_window) {
if (popup_window.closed) {
// opened OK but was closed before we checked
cb(false);
return;
}
if (/chrome/.test(navigator.userAgent.toLowerCase())) {
// wait a bit before testing the popup in chrome
setTimeout(function() {
cb(_is_popup_blocked(popup_window));
}, CHROME_CHECK_TIME);
} else {
// for other browsers, add an onload event and check after that
popup_window.onload = function() {
cb(_is_popup_blocked(popup_window));
};
}
} else {
cb(true);
}
};
Jason's answer is the only method I can think of too, but relying on position like that is a little bit dodgy!
These days, you don't really need to ask the question “was my unsolicited popup blocked?”, because the answer is invariably “yes” — all the major browsers have the popup blocker turned on by default. Best approach is only ever to window.open() in response to a direct click, which is almost always allowed.
HI
I modified the solutions described above slightly and think that it is working for Chrome at least.
My solution is made to detect if popup is blocked when the main page is opened, not when popup is opened, but i am sure there are some people that can modify it.:-)
The drawback here is that the popup-window is displayed for a couple of seconds (might be possible to shorten a bit) when there is no popup-blocker.
I put this in the section of my 'main' window
<script type="text/JavaScript" language="JavaScript">
var mine = window.open('popuptest.htm','popuptest','width=1px,height=1px,left=0,top=0,scrollbars=no');
if(!mine|| mine.closed || typeof mine.closed=='undefined')
{
popUpsBlocked = true
alert('Popup blocker detected ');
if(mine)
mine.close();
}
else
{
popUpsBlocked = false
var cookieCheckTimer = null;
cookieCheckTimer = setTimeout('testPopup();', 3500);
}
function testPopup()
{
if(mine)
{
if(mine.test())
{
popUpsBlocked = false;
}
else
{
alert('Popup blocker detected ');
popUpsBlocked = true;
}
mine.close();
}
}
</script>
The popuptest looks like this:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
<title>Popup test</title>
<script type="text/javascript" language="Javascript">
function test() {if(window.innerHeight!=0){return true;} else return false;}
</script>
</head>
<body>
</body>
</html>
As i call the test-function on the popup-page after 3500 ms the innerheight has been set correctly by Chrome.
I use the variable popUpsBlocked to know if the popups are displayed or not in other javascripts.
i.e
function ShowConfirmationMessage()
{
if(popUpsBlocked)
{
alert('Popups are blocked, can not display confirmation popup. A mail will be sent with the confirmation.');
}
else
{
displayConfirmationPopup();
}
mailConfirmation();
}
function openPopUpWindow(format)
{
var win = window.open('popupShow.html',
'ReportViewer',
'width=920px,height=720px,left=50px,top=20px,location=no,directories=no,status=no,menubar=no,toolbar=no,resizable=1,maximize:yes,scrollbars=0');
if (win == null || typeof(win) == "undefined" || (win == null && win.outerWidth == 0) || (win != null && win.outerHeight == 0) || win.test == "undefined")
{
alert("The popup was blocked. You must allow popups to use this site.");
}
else if (win)
{
win.onload = function()
{
if (win.screenX === 0) {
alert("The popup was blocked. You must allow popups to use this site.");
win.close();
}
};
}
}
As far as I can tell (from what I've tested) Chrome returns a window object with location of 'about:blank'.
So, the following should work for all browsers:
var newWin = window.open(url);
if(!newWin || newWin.closed || typeof newWin.closed=='undefined' || newWin.location=='about:blank')
{
//POPUP BLOCKED
}
