Cannot close parent window using javascript in Firefox 2.0
Dear Sirs,
We have encountered a problem in our site using Firefox 2.0 that the parent window cannot be closed via calling the following javascripts in inner frames, which works in Firefox 1.5. And, we found error message "Scripts may not close windows that were not opened by script" in Error Console. Should there have an alternative solution for it? Thanks a lot!
===========================
<script>
function closeWin() {
if(navigator.appName=="Microsoft Internet Explorer") {
window.parent.window.opener=null;
window.parent.window.close();
} else if(navigator.appName=="Netscape") {
top.window.opener = top;
top.window.open('','_parent','');
top.window.close();
}
}
</script>
===========================

That is a true statement. You might be able to request elevated privileges to close the window; that would be at the user's discretion. However, why do you need to close the window if your application did not open it?

I encountered the same problem
Hi,
I encountered the same problem, i have a javascript function as follows, which works in firefox 1.0 and 1.5 but doesnt work in 2.0. please do help me in resolving this:
the function is:
function closeWindow() {
window.open('','_parent','');
window.close();
}
This also doesnt work in netscape 8.0. though it works in 7.2.
please let me know any of you know what the problem is ASAP, which would be greatly appreciated.

Yes, that doesn't do anything. If I change the missing URL in the window.open command to an actual page, it executes but then the next line doesn't run or doesn't do anything. The following variation gives the usual script error for the close() method in this scenario -- can't close a window not opened by a script:
Code: Select all
function closeWindow() {
newwin = window.open(location.href,'_parent','');
newwin.close();
}
Apparently, a loophole has been closed.
Why do you need this?

My product has a setup application, after completing which it has a Close button. After clicking this button, the window should be closed.
thanks for the solution, but if i add this code, in firefox, it didnt close the window but i got "Error 500--Internal Server Error". and in netscape, a new window with same url is opened and closed. but the current is not closed. what could be the problem? As im a novice in javascript i couldnt make out the problem. please help.
I am calling this from a jsp where the "onclick" is used to call the function.
Thnx,

I've run into this as well. I found a bunch of workarounds on the www, but it seems that they were all written with FF 1.x in mind.
I'm sure there will be arguments to the contrary, and flame wars will incite, but here are the reasons I need it:
- Existing intranet application used by both IE and FF users.
- The "Logout" button has always closed the window in the past, and continues to do so in IE.
- It's not up to me to rearchitect the application and/or retrain the users to say, "Well, sometimes it closes, sometimes it doesn't...Sorry 'bout that."
Now, without telling me, "Closing the window is bad form. User's don't like it.", is there *any* workaround or piece of code that will implement this?

If you launch the initial Firefox window using window.open, then window.close should work on it. However, if it is launched from a regular URL, then as you know it doesn't work. There is a way to ask the user for extra permissions. However, that might be more annoying than leaving the window open...

I was testing with a plain .html file in the <iframe>. I think your .jsp file is not meant to be used in that way, so never mind on the example.

Jeff, I think you can request the user to approve elevated privileges. In an intranet environment, you might be able to push out a change to Firefox's prefs.js file that would pre-approve your internal server to be able to access this feature. However, I haven't tried it myself.

The method I mentioned, to request permission from the user, is explained in this article. You need the UniversalBrowserWrite privilege: http://www.mozilla.org/projects/securit ... html#privs

If you want Firefox to be changed, file a bug (first see if there is one already). This is a user-to-user forum, and you already know the answer we can give.
