The proper way to handle popup closing - javascript

I'm looking for close event for popup. I've found one for XUL, but I need it for HTML.
Popup has closed property.
>>> var popup = open('http://example.com/', 'popup', 'height=400,width=500');
>>> popup.closed
false
Well, I can check it once at half second.
function open_popup() {
var popup = open('http://example.com/', 'popup', 'height=450,width=450');
var timer = setInterval(function(){
if (popup.closed) {
alert('popup closed!');
clearInterval(timer);
}
}, 500);
}
I've tested it on Chrome 4.0.249.27, Opera 10.10, Safari 4.0.4, and Firefox 3.5.5. All works fine.
But setInterval bother me. It is ugly. Is there a better way of doing this?
UPDATE:
I use popups for authentication dialog (oAuth, actually). I wanna send some data to parent window after popup close (through postMessage).
Page inside popup from another domain. So, I can not add any event (unload) to it due security restrictions.
I can not use iframe due to iframe buster script. So, I can not use any fancy jQuery modal dialogs.
I can not edit anything inside popup.

You might want to look into the unload event, take a look at Javascript: Popups
edit: as you've said you cannot edit anything inside the popup, there really aren't any options left. I believe your current setInterval code does the job just fine. You should ask yourself if realtime detection of the popup closing is absolutely critical. That 500 milliseconds timer certainly won't strain hardly any resources or bring someones computer to its knees.

I have used jQuery Dialog and it has a close event
http://jqueryui.com/demos/dialog/.
Am not sure if I understand your question right,why do you want to use the timer ?

Use window.opener in the pop-up window. i.e. something like:
onunload = opener.alert('popup closed');
or
onunload = opener.nameOfAFunction();

How to close opened tabs in browser using javascript [duplicate]

I want to create a link on a webpage that would close the currently active tab in a browser without closing other tabs in the browser. When the user clicks the close link, an alert message should appear asking the user to confirm with two buttons, "YES" and "NO". If the user clicks "YES", close that page and If "NO", do nothing.
How can it be done? Any suggestions?
You will need Javascript to do this. Use window.close():
close();
Note: the current tab is implied. This is equivalent:
window.close();
or you can specify a different window.
So:
function close_window() {
if (confirm("Close Window?")) {
close();
}
}
with HTML:
close
or:
close
You return false here to prevent the default behavior for the event. Otherwise the browser will attempt to go to that URL (which it obviously isn't).
Now the options on the window.confirm() dialog box will be OK and Cancel (not Yes and No). If you really want Yes and No you'll need to create some kind of modal Javascript dialog box.
Note: there is browser-specific differences with the above. If you opened the window with Javascript (via window.open()) then you are allowed to close the window with javascript. Firefox disallows you from closing other windows. I believe IE will ask the user for confirmation. Other browsers may vary.
Try this
close
This method works in Chrome and IE:
<a href="blablabla" onclick="setTimeout(function(){var ww = window.open(window.location, '_self'); ww.close(); }, 1000);">
If you click on this the window will be closed after 1000ms
</a>
As far as I can tell, it no longer is possible in Chrome or FireFox. It may still be possible in IE (at least pre-Edge).
Sorry for necroposting this, but I recently implemented a locally hosted site that had needed the ability to close the current browser tab and found some interesting workarounds that are not well documented anywhere I could find, so took it on myself to do so.
Note: These workarounds were done with a locally hosted site in mind, and (with the exception of Edge) require the browser to be specifically configured, so would not be ideal for publicly hosted sites.
Context:
In the past, the jQuery script window.close() was able to close the current tab without a problem on most browsers. However, most modern browsers no longer support this script, potentially for security reasons.
Current Functionality:
window.close() will work on tabs opened by a script, or by an anchor with target="_blank" (opened in a new tab)
See #killstreet's comment on #calios's answer
Browser Specific work-arounds:
Google Chrome:
Chrome does not allow the window.close() script to be to be run and nothing happens if you try to use it. By using the Chrome plugin TamperMonkey however we can use the window.close() method if you include the // #grant window.close in the UserScript header of TamperMonkey.
For example, my script (which is triggered when a button with id = 'close_page' is clicked and if 'yes' is pressed on the browser popup) looks like:
// ==UserScript==
// #name Close Tab Script
// #namespace http://tampermonkey.net/
// #version 1.0
// #description Closes current tab when triggered
// #author Mackey Johnstone
// #match http://localhost/index.php
// #grant window.close
// #require http://code.jquery.com/jquery-3.4.1.min.js
// ==/UserScript==
(function() {
'use strict';
$("#close_page").click(function() {
var confirm_result = confirm("Are you sure you want to quit?");
if (confirm_result == true) {
window.close();
}
});
})();
Note: This solution can only close the tab if it is NOT the last tab open however. So effectively, it cannot close the tab if it would cause window to closes by being the last tab open.
Firefox:
Firefox has an advanced setting that you can enable to allow scripts to close windows, effectively enabling the window.close() method. To enable this setting go to about:config then search and find the dom.allow_scripts_to_close_windows preference and switch it from false to true.
This allows you to use the window.close() method directly in your jQuery file as you would any other script.
For example, this script works perfectly with the preference set to true:
<script>
$("#close_page").click(function() {
var confirm_result = confirm("Are you sure you want to quit?");
if (confirm_result == true) {
window.close();
}
});
</script>
This works much better than the Chrome workaround as it allows the user to close the current tab even if it is the only tab open, and doesn't require a third party plugin. The one downside however is that it also enables this script to be run by different websites (not just the one you are intending it to use on) so could potentially be a security hazard, although I cant imagine closing the current tab being particularly dangerous.
Edge:
Disappointingly Edge actually performed the best out of all 3 browsers I tried, and worked with the window.close() method without requiring any configuration. When the window.close() script is run, an additional popup alerts you that the page is trying to close the current tab and asks if you want to continue.
Edit:
This was on the old version of Edge not based on chromium. I have not tested it, but imagine it will act similarly to Chrome on chromium based versions
Final Note: The solutions for both Chrome and Firefox are workarounds for something that the browsers intentionally disabled, potentially for security reasons. They also both require the user to configure their browsers up to be compatible before hand, so would likely not be viable for sites intended for public use, but are ideal for locally hosted solutions like mine.
It is possible. I searched the whole net for this, but once when i took one of microsoft's survey, I finally got the answer.
try this:
window.top.close();
this will close the current tab for you.
The following works for me in Chrome 41:
function leave() {
var myWindow = window.open("", "_self");
myWindow.document.write("");
setTimeout (function() {myWindow.close();},1000);
}
I've tried several ideas for FF including opening an actual web-page, but nothing seems to work. As far as I understand, any browser will close a tab or window with xxx.close() if it was really opened by JS, but FF, at least, cannot be duped into closing a tab by opening new content inside that tab.
That makes sense when you think about it - a user may well not want JS closing a tab or window that has useful history.
Try this as well. Working for me on all three major browsers.
<!-- saved from url=(0014)about:internet -->
<a href="#" onclick="javascript:window.close();opener.window.focus();" >Close Window</a>
window.close() doesn't work in 2k21 because Scripts may close only the windows that were opened by them.
BUT if the tab is opened in the browser not manually, but automatically - then window.close() works.
Automatically (when close() works):
<a href="/close" target="_blank"> the browser will open address in the new tab and this tab can be closed with close()
when new browser tab is opened from another application (when you click a link in Telegram/Whatsup/Outlook etc) - OS will open new tab and it can be closed with close()
when you open the with window.open('ya.ru') - for sure it can be closed with close()
Manually (when it doesn't work):
when you open fresh browser and type in the address.
when you click (+) to open new tab and type in the address
Tested successfully in FF 18 and Chrome 24:
Insert in head:
<script>
function closeWindow() {
window.open('','_parent','');
window.close();
}
</script>
HTML:
Close Window
Credits go to Marcos J. Drake.
As for the people who are still visiting this page, you are only allowed to close a tab that is opened by a script OR by using the anchor tag of HTML with target _blank. Both those can be closed using the
<script>
window.close();
</script>
<button class="closeButton" style="cursor: pointer" onclick="window.close();">Close Window</button>
this did the work for me
a bit late but this is what i found out...
window.close() will only work (IE is an exception) if the window that you are trying to close() was opened by a script using window.open() method.
!(please see the comment of #killstreet below about anchor tag with target _blank)
TLDR: chrome & firefox allow to close them.
you will get console error:
Scripts may not close windows that were not opened by script.
as an error and nothing else.
you could add a unique parameter in the URL to know if the page was opened from a script (like time) - but its just a hack and not a native functionality and will fail in some cases.
i couldn't find any way to know if the page was opened from a open() or not,
and close will not throw and errors.
this will NOT print "test":
try{
window.close();
}
catch (e){
console.log("text");
}
you can read in MDN more about the close() function
It is guaranteed that the closing of tabs will not be tolerated in any future browsers. Using scripts like mentioned above will not work.
My solution was to use a Chrome Extension. A Chrome Extension can require tab manipulation permissions so it will be easy to handle the closing of any tab from the domain in which the extension's content script is active.
This is how the background script should look like:
chrome.runtime.onMessage.addListener(function(message, sender, sendResponse) {
console.log(sender)
console.log(message)
if(message.closeThis) {
closeTab(sender.tab.id)
}
});
const closeTab = id => {
console.log("Closing tab");
chrome.tabs.remove(id);
}
The content script should look like this:
window.addEventListener("message", (event) => {
// Only accept messages from ourselves
if (event.source !== window)
return;
if (event.data.type && (event.data.type === "APPLICATION/CLOSE")) {
console.log("Content script received APPLICATION/CLOSE event");
chrome.runtime.sendMessage({closeThis: true});
}
}, false);
Close the tab by calling this in your application (make sure the content scripts are enabled in your domain by specifying that in the manifest):
window.postMessage({ type: "APPLICATION/CLOSE" }, "*");
Be cautious when using this because Chrome Extensions' deployment can be a pain.
I just wanted to add that window.close() works in 2021, chrome 91, but not always. One of the cases when it works if there is no history in tab (you can't go back).
In my case I wanted to create self-destructing tab which closes after few seconds, but I was struggling with how to go to development server avoiding new tab, because apparently New tab is also tab and it is being saved in tab history :D I created link in about:blank tab with target=_blank attribute and it was leading to new tab where window.close() method finally worked!
This is one way of solving the same, declare a JavaScript function like this
<script>
function Exit() {
var x=confirm('Are You sure want to exit:');
if(x) window.close();
}
</script>
Add the following line to the HTML to call the function using a <button>
<button name='closeIt' onClick="Exit()" >Click to exit </Button>
You can try this solution to trick the browser to close the current window using JavaScript + HTML:
JS:
function closeWindow() {
if(window.confirm('Are you sure?')) {
window.alert('Closing window')
window.open('', '_self')
window.close()
}
else {
alert('Cancelled!')
}
}
HTML:
Some content
<button onclick='closeWindow()'>Close Current Window!</button>
More content
Due to strict browser behaviors, window.close() will only work if it's opened by window.open(...)
But I made a solution for this!
Add an empty hashtag with window.open(...) when it is NOT included
When the perfect time for closing occurs, call window.close
If 2. has returned an error, replace any hashtag or HTTP parameters with an empty hashtag and finally close the window
<button onclick="myFunction()">Close</button>
<script>
if (location.href.indexOf("#") == -1) {
window.open(location.href + "#", "_self")
}
function myFunction() {
try {
window.close()
} catch (err) {
window.open(location.href.substring(0, location.href.indexOf("?")).substring(0, location.href.indexOf("#")) + "#", "_self")
window.close()
}
}

How to refresh page after focus?

I would like to refresh a page after it got back into the focus. For the refreshing part I thought I might just use:
location.reload();
The tricky part is how do I determine when to refresh?
First the window has to loose the focus (which could be determined through .blur() I assume).
Only after the window which lost focus gets back into focus should trigger the refresh of itself. Can I use .focus() on location? Or do I have to use something else here?
How can I combine these two cases?
What would your approach be?
Try this:
var blurred = false;
window.onblur = function() { blurred = true; };
window.onfocus = function() { blurred && (location.reload()); };
This only reloads the page if it has been hidden
I don't recommend binding to the window focus in jQuery, the Page will reload on pretty much every user action.
Update
This heavily relies on the browser implementation of window.onfocus and window.onblur. Webkit may not support the onblur event (in my chromium it didn't) where firefox calls a blur if the page is hidden.
In my development environment I add this snippet of JS to a page - whenever the page becomes active after becoming inactive it reloads, so for example if you type in your text editor then click back onto your browser the page will reload once without an infinite loop. It also works when chaining active tab or active window within the same browser session.
window.onblur= function() {window.onfocus= function () {location.reload(true)}};
As stated above this does depend on browser implementation but works fine in chrome.
#Eamonn 's approach works good for chrome as mentioned by him.
For Firefox:
window.disableResetPrompt;
window.onblur= function() {window.onfocus= function () {location.reload(true)}};

Gray-out the background when popup opens

I call below javascript on click of link/textbox or button.
function OpenPopupLinkRisk(Number)
{
window.open("../PopUp.aspx?id=" + Number, "List", "scrollbars=no,resizable=yes,width=700,height=450");
return false;
}
I donot want user to do anything else until he closes the popup window. So how can I grey background and force user to first close the popup and then do any other activity on application.
Can anyone suggest me how to achieve this ?
Thanks !
First of all, i would really disrecommend using window.open for this unless you really need a new browser popup window. If you want to stick with it persee, then will have to use a timer or something to manually check when the window is closed like:
var popup = window.open('http://www.example.com', 'example', '');
var timer = setInterval(function() {
if(window.closed) {
clearInterval(timer);
alert('Closed alright');
}
}, 100);
Else, check some tutorials on the subject, Modal Popup
First a direct solution to you problem that I wouldn't advice using it an then an approach you should be taking and is better from usability as well as security point of view.
Check whether popup window has closed
// mask your page
mask();
// open popup
var popup = window.open("../PopUp.aspx?id=" + Number);
// check whether it's been closed
function check()
{
if (popup && !popup.closed)
{
setTimeout(check, 1000);
}
// unmask your page
unmask();
}
check();
Modern (and better) alternative
Using window.open is a bad solution because it's a security risk and popup blockers prevent sites to open new windows. It's also considered bad practice.
A much better modern alternative is to display the new page as modal window inside your page directly. This will not open new windows and users stay as they are.
There are tons of javascript plugins for modal windows. Make a Google search.

set the focus of a popup window every time

I have two pages one.html and two.html
I am opening a new window using following code
//here popup is a global variable
popup=window.open('two.html','two');
for the first time a popup window open successfully and get the focus but
if I try to open it again without closing already opened popup then two.html is not getting focus for the second time.
note: I have set popup window's name as 'two'
You can use the focus function, as used below:
<script language="javascript" type="text/javascript">

Directly append the focus() to the window.open protoype
My empiric solution that always works:
setTimeout('detail.focus()', 1);
Appending .focus() right after open does not always work, nor calling a .focus() without setTimeout.
I know it's ugly (wanted to get rid of it right now, after some years, with no success), and I do not know the exact reasons why and how, but it works.
You can close the popup before you open it if you check to see if the popup is already open when you call the function.
var popup;
​function openPop() {
if ("close" in popup) popup.close();
popup = window.open("http://stackoverflow.com", "test", "width=200, height=200");​​​​​​​​
}
​This will ensure the popup always appears on top.
var win = window.open('two.html','two');
win.document.getElementsByTagName("body")[0].focus(); //focus the body rather than the window.
Check your Firefox 2 settings at
Go to Tools -> Options -> Content
Make sure "Enable JavaScript" is turned on.
Next to "Enable JavaScript", click the "Advanced" button.
Make sure that there is a check-mark in the box
[x] Raise or lower windows
If the setting "Raise or lower windows" is turned off, then
this disables the window.focus() method.
I found an answer for myself that works. In the html of the popup body, add to the body tag onload="this.window.focus()". Even if you minimize the window, it pops back up front and center. Be sure and name the window in your execution script window.open('url','some name','vars'); Hope this helps you!
Unfortunately some modern browsers still don't support focusing tabs, see this Firefox bug entry, for example.
However, the following code is working well for me. As a workaround, it reopens a window/tab if it cannot be focussed:
var win = window.open("two.html", "two")
win.focus();
setTimeout(function() {
if(document.hasFocus()) {
win.close();
window.open("two.html", "two")
}
}, 1);
In the first line it opens the window and tries to focus it using the second line. If a window with the name two is already there, no new window/tab is opened, but it's reused.
The trick now is, that we check if the current window still has focus using document.hasFocus(). If so, we close the window and reopen it. This is only for browsers which don't support focusing the tab which is to be reused directly. Currently, this is the case for FF and IE/MS Edge. Chrome works well.
However, directly after using window.open, document.hasFocus() always returns true (so said, also in Chrome). The workaround is to use setTimeout one ms later.
just add .focus() to the window.open line
window.open('two.html','two').focus()
I did have same problem and this seems to work in both Firefox and Chromium web browsers.
In my web thaiiceland.com I noticed that if the popup was open, the focus didn't go on the popup and you feel nothing happen when you click on that link. So I search and after try to just add .focus() in the end of the window.open line it works.

setTimeout(function () {
window.open('PageName', '', 'height=560,width=1120,resizable=no,left=100,top=50,screenX=100,screenY=50');
}, 100);
-> This code is use for giving focus on newly open window.
-> Put it in javascript.('setTimeout is inbuilt function of javascript')
-> Many time happen that when popup window is opened, it will go behind the old window, So above is very useful to focus for new window.
It is a one liner solution, use focus on your pop up var:
popup=window.open('two.html','two');
popup.focus();
This will always open your pop up window even if it is not closed.
