I am opening a paypal window from the parent with window.open(). After payment and redirecting back to my page (in the popup window), I would like to close the popup and update the parent window URL.
I found out this works over window.opener.location.
However the console shows
window.opener.location is null
after redirection because as the child window changes, the popup looses the information about the opener.
Well great. Now is there any way to get around this? Maybe adding a sort of "listener" to the parent who listens to the URL of the child?
window.opener is removed whenever you navigate to a different host (for security reasons), there is no way around it. The only option should be doing the payment in a frame if it is possible. The top document needs to stay on the same host.
First you can have a timer function in the parent windows to check whether the child window is opened or closed at particular time interval say 100ms or so. If it is closed then you can reload the parent window.
The issue with window.opener in IE is when you using localhost site and the internet site like paypal. Simply change location of your local host from Local Intranet to the Internet zone and the opener will not be null.

I am trying to detect whether the current page is already opened in a different tab or not.
I tried using window.open(), but I get as return the current window itself, not the supposedly other window of same address. It will always return true.
So say, if 'mysite.com' is already opened, when the user opens a new window with 'mysite.com', I shall detect that, focus the other window and close the current one.
Would love to hear any ideas, or whether this is possible. I'm trying to capture all links into a single tab.
You can use localStorage events to communicate between different tabs and therefore detect if a page is already opened. Check this answer: https://stackoverflow.com/a/14792159/60745
Even when you're only concerned with a tab in the same browser on the same machine, the problem with trying to accomplish this through pure javascript is that although you could set a cookie on each of your sites pages (window.onload) to record the user has initially visited your site, there's no safe way to ensure you remove this cookie when they leave.
Although you have the onunload & onbeforeunload events, these are not fired when you leave a site over a link, uses a browsers back button or closes the browser.
can browser popout windows be launched (like google talk conversation windows can be popped out into a new window from the main gmail page.) so they are still part of the main page i.e. share resources and access and modify each other, e.g. if the popout window contained a button it can be clicked and modify part of the original page without having to go to the server? I'm guessing the answer is no, but as I don't know for sure I thought I'd ask.
You can access the popout parent by using the window.opener property from within the 'popout' window. That will give you the window object of the parent.
So if on your main page you have a global variable test
var test = 'Hello';
It can be accessed from the child window using
window.opener.test
My site opens up a popup window to an external site, but at some point, the popup window will redirect to my site again. Because of security reasons, I know I can't look at the popup window URL until it redirects to back to my site. What I did is kept checking every second to see whether I could access the url address, and once I could, (meaning the popup window was back on my site) I stored the Url info and closed the popup. This seems like a pretty bad way of doing it...
Is there any way to detect the window returning to my site?
If you have control over the linkback page for the popup then you can set up a special page just for this purpose. All you'd need to do would be to create a page with some javascript that runs to notify you that you have come full circle.
One property that popup windows have is the window.opener property which refers to the parent window that initially created the pop-up.
This should be a good place to start.
I'm building an app that involves authentication via third-party. To make the process not redirect the actual app I open a new window that then does the authentication and returns to main window after success.
This doesn't, however, go as well as planned. When the popup redirects to third-party and back, window.opener gets null. It's still possible to close the popup by window.close() but I also need to refresh the logged-in-area in the main window, like this:
window.opener.check_auth_status();
I really hope there is a way to fix this, e.g. binding a function to popup-close in the main window? Refreshing the whole page would be highly unnecessary.
One way is to set an interval to main window checking if the popup is closed, but this seems so fiddly.
You have a few options that may or may not work in the latest versions of the browsers due to security updates
1) check that the window is closed from the opener - not fiddly and actually the safest
2) give the opener a name
window.name="myMainWindow";
and in popup (script from SAME domain) - should normally not open a new window or change content
var handle = window.open("","myMainWindow");
handle.check_auth_status();
3) use an iFrame in the popup and when you want to access the opener, use top.opener
I have a page located at x.com. On this page is a button that, when clicked, will launch a new window (using javascript's window.open() method) to a page that is located at z.com. The popup does a few things, then redirects the original window (the opener, x.com) to a different page based on some parameters defined in the popup.
This works fine in Firefox/Chrome, but not in IE. In IE (8 specifically, but I believe 7 also has this problem) the original window (the opener) is not redirected. Instead, a new window comes up and THAT window is redirected.
I've tried many different methods to try and get this to work, including changing the popup to an iframe loaded on the page and having a function on the opener that the popup/iframe call. The problem seems to be that IE refuses to allow cross-domain sites to talk to each other via javascript.
Is there a way around this? How can I get the parent window to redirect to a page based on parameters in a popup or iframe?
EDIT:
Here is some code for samples:
In a page on domainA.com, I have this:
<img src='/images/test.png' onclick="window.open('http://www.domainB.com/item.aspx', 'name', 'width=100,height=100,menubar=no,status=no,toolbar=no');" />
In item.aspx on domainB.com I have this in the javascript:
opener.location.href = 'http://www.somethingelse.com/';
In Firefox/Chrome, this works fine. In IE, when domainB.com tries to set location.href on opener (aka the parent window, which is domainA.com), it instead opens a new window, which is not what I want. I want it to redirect the opener (parent window) to the URL I specified.

Hi I solved my problem by doing the following
instead of using window.opener.location = "....
Use window.opener.document.location = "url". This worked for me.
Another thing is make sure that you are not redirecting from http into https this will also cause it to break.
Cheers
I ended up resolving it by doing the following:
I added an iFrame to my main page. The iFrame is in the same domain as my popup. The iFrame contains a button that, when clicked, will launch the popup.
The popup does it's thing, then changes the iFrame's hash tag to something like #change (so the url would be www.whatever.com/iframe.aspx#change). In the iFrame's javascript, I have a loop going that checks the hash to see if it says "change" and if so, it will redirect the parent page to wherever I want. This works beautifully.
Because I did not want the infinite loop on every single page, I do a browser check so that this only applies to IE. For all other browsers I just use window.opener which works fine.
