I am opening a modal popup window. Then I access a parent window textbox and other attributes using window.opener. It is working fine in firefox but not in IE8. It gives error 'window.opener is null'. How can I access parent window attributes in child window which works in both browsers.
There are two ways to solve the problem:
Note: "window.opener" is not supported by IE if "showModalDialog" is been used.
1) Instead of "window.showModalDialog" use "window.open"
2) If you want to use "window.showModalDialog" then do the following:
<script language="javascript" type="text/javascript">
function YourFunction()
{
var opener = null;
if (window.dialogArguments) // Internet Explorer supports window.dialogArguments
{
opener = window.dialogArguments;
}
else // Firefox, Safari, Google Chrome and Opera supports window.opener
{
if (window.opener)
{
opener = window.opener;
}
}
// write you code and refer "opener"
window.close();
}
</script>
You can pass arguments to showModalDialog function. Simply pass window object as an argument.
window.showModalDialog(theURL, window);
Yo can access the arguments from the modal window using dialogArguments. See: http://msdn.microsoft.com/en-us/library/ms533723%28VS.85%29.aspx
var openerWindow = window.dialogArguments;
Disable Internet Explorer's "Protected Mode", which prevents access to this object.
The steps for this are:
Press Alt+T to show the Tools menu
Click "Internet options"
Select the "Security" tab
Make sure zone selected contains your site. For an intranet site it would typically be "Local intranet" zone.
Untick "Enable Protected Mode"
Close all IE tabs and windows and re-open.
Now you should be able to access the window.opener object.
The approach I would take is the following:
Use an existing JavaScript UI library because you are not the first person to ever want to do this, failing that
Create a function called OpenWindow, that browser sniffs for the window.opener method
For example:
if(window.opener == undefined) {
//probably not Firefox...
}
and if it finds it then uses it, else it tests for the IE variant and uses it. And then it checks Safari's version, etc...
As a cross-browser alternative, you can give a custom attribute to the new window while you are opening it:
var popup = window.open(...);
popup.isPopup = true;
Then, in the referred page:
if (window.isPopup) {
// Do something
}
else {
// Not in a popup
}

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()
}
}
</script>

I am using showModalDialog() in my application, for user to view articles from different sources as modal popup.
It work fine with FF and IE, but in chrome it's not behaving as modal, I can still go on parent window and click on any element in it.
I wanted to make it work same as IE and FF.
I have looked at few work-around
1) set onfocus event on parent window, and focus child again on it.
<script type="text/javascript">
setInterval(checkFocus, 10);
var mywindow;
function openModal() {
var a = new Array;
a[0] = 1;
a[1] = 4;
mywindow = window.showModalDialog(myurl,
a, "dialogwidth: 1000; dialogheight: 700; resizable: yes;center : yes;");
}
function checkFocus() {
if (mywindow != null && mywindow != undefined) {
if (window.focus) {
mywindow.focus();
}
}
}
</script>
but this is not seems to work as expected.
2) set onblur event on child window, to focus itself again
this solution i have read from some online sources. i can apply this solution if only child window is customized page from on my domain only , but as my child window can be any url from any domain It is not applicable in my case.
I need to make it work , can anybody suggest me on this??
Chrome has serious bugs with its implementation. Most importantly the window Chrome displays isn’t modal (see Chromium bug #16045), meaning, the user is able to interact with the original window before dealing with the modal dialog.
I can't seem to figure out why the following simple popup will not work in IE9. FF & Chrome popup as expected, but IE does not appear to do anything when the link is clicked. I tried the IE9 debugger, but didn't get any helpful information out of it.
In the head section:
<script type="text/javascript" language="JavaScript">
function JSPopup(linkref) {
window.open(linkref,"Report Definitions","width=600,height=480");
return false;
}
In the body:
<strong>Report Definitions</strong>
Thanks for your help,
Filip
Turns out the problem was the name given to the popup - IE doesn't allow spaces, FF & Chrome do:
window.open(linkref,"Report Definitions","width=600,height=480");
needed to be changed to:
window.open(linkref,"ReportDefinitions","width=600,height=480");
This works across browsers.

This is part of the security changes made in IE6. Now you can only call "window.open" from within a user-initiated event. For example, your code would work inside an element's onclick event. The "window.open" http://msdn.microsoft.com/en-us/library/ms536651(VS.85).aspx MSDN page says this:
"This method must use a user-initiated action, such as clicking on a link or tabbing to a link and pressing enter, to open a pop-up window. The Pop-up Blocker feature in Internet Explorer 6 blocks windows that are opened without being initiated by the user."
Example...
function popUpWin(url,wtitle,wprop){
if (!window.open){ return; } // checking if we can't do this basic function
// Kill if(win), since win was a local var this was a usless check
var win = window.open(url,wtitle,wprop);
// next line important in case you open multiple with the same 'wtitle'
// to make sure the window is reused and refocused.
if (win && win.focus){ win.focus(); }
return false;
}
From a child popup window (opened using window.open), I am trying to change the URL of the window that opened me, e.g.
window.opener.location.href = 'http://www.google.com';
In all browsers this works wonderfully, except for IE8 (and I am somewhat sure it worked in previous IE8. Maybe a security update kills this).
In IE8 what happens is that the line above is treated as a request to open a NEW window with the address and the original opener window stays the same. And, since I am not putting this line inside an onclick event, this is treated as a popup.
So how do I do this in IE8? How do I change the opener location?
It looks like this is just not possible. I got no answer from anybody and all my research indicated that this is just another way MS added to block popups.
try to move action into parent window, like this:
//parent.htm
function changeUrl(url) {
location.href = url;
window.reload();
}
window.open("child.htm");
.....
//child.htm
window.opener.changeUrl(url);
try this:
on the opener window define a function called goto ;-)
function goto(url){ window.location.href = url; }
now from the child window call window.opener.goto(url);
i have Problem with opening popups in javascript i have this function to open my popups in IE6 and IE7:
function open_window(Location,w,h) //opens new window
{
var win = "width="+w+",height="+h+",menubar=no,location=no,resizable,scrollbars,top=500,left=500";
alert(win) ;
window.open(Location,'newWin',win).focus();
}
it's working . i mean my new window opens but an error occurs. The Error Message is :
'window.open(...)' is null is not an object.
do you want to countinue running script on this page ?
then i have button in onclick event it's will call a function to close current window an refresh the opener function is
function refreshParent(location)
{
window.opener.location.href = location ;
window.close();
}
it's also gives me error : window.opener.location is null or not an object but i'm sure i'm passing correct parameters
i call it like this :
for second part :
<input type="button" name="pay" value="test" onclick="refreshParent('index.php?module=payment&task=default')" >
for first part :
<a onclick="javascript:open_window('?module=cart&task=add&id=<?=$res[xproductid]?>&popup=on','500' , '500')" style="cursor:pointer" id="addtocard"> <img src="../images/new_theme/buy_book.gif" width="123" border="0"/> </a>
it's really confuse me . Please Help ;)
When popup windows opened using window.open are blocked by a popup blocker, a feature of pretty much any modern browser these days, the return value of window.open() is not a window object, but null.
In order to circumvent these issues you would need to test the value returned by window.open() before attempting to invoke any methods on it.
Below is a piece of code to demonstrate how to go around this problem:
function open_window(Location,w,h) //opens new window
{
var options = "width=" + w + ",height=" + h;
options += ",menubar=no,location=no,resizable,scrollbars,top=500,left=500";
var newwin = window.open(Location,'newWin',options);
if (newwin == null)
{
// The popup got blocked, notify the user
return false;
}
newwin.focus();
}
In general, popup windows should be used only as a last resort or in controlled environments (internal company website, etc). Popup blockers tend to behave in very inconsistent ways and there may be more than a single popup blocker installed in a given browser so instructing the user on how to allow popups for a given website is not necessarily a solution. Example: IE7 + Google toolbar = two popup blockers.
If I may suggest, perhaps you should consider using something like this:
http://jqueryui.com/demos/dialog/
The advantages are numerous:
Skinnable, so you can create a more consistent look to match your website.
No popup blockers.
Good API and documentation that is consistent across most, if not all, major browsers.
If you still require that the newly opened "window" contain an external URL, you could use an IFRAME inside the opened dialog window.
Hope this helps,
Lior.
Works perfectly fine for me. Tested in IE6/7/8.
Of course I couldn't test it with your URLs so I replaced these with simple filenames. I'd suggest you try it also with simple filenames and see if it also fails then.
Beside that...
You don't need to add "javascript:" at the beginning of onclick attribute value.
It would also be good if you added a href="..." attribute to the link with the same URL that you give to open_window. Then it would become a real link and you wouldn't have to add cursor:pointer to it. For example:
<a href="?module=cart&task=add&id=<?=$res[xproductid]?>&popup=on"
onclick="open_window(this.href, '500' , '500'); return false;"> ...
Here is a way to have your cake and eat it too
I have not tested it on all browsers but it should really work
function open_window(url,target,w,h) { //opens new window
var parms = "width="+w+",height="+h+",menubar=no,location=no,resizable,scrollbars,top=500,left=500";
var win = window.open(url,target,parms);
if (win) {
win.focus();
return false; // cancel the onClick
}
return true; // make the link perform as normal
}
Using the link
<a href="?module=cart&task=add&id=<?=$res[xproductid]?>&popup=on"
target="newWin"
onclick="return open_window(this.href,this.target,500,500)"
id="addtocard"><img src="../images/new_theme/buy_book.gif" width="123" border="0"/></a>
which even saves you the silly cursor thing since it is an actual link which works even when JS is turned off
