window.close()

[Heinrich Wolf]

Hi all,

Please direct me to a current treatise of window.close().

My info is that a window can be closed provided it has
been opened by the same script or functions within the
same document.

And this is as far as I've got, but no success:

function window(url) {
var pdf = window.open (url,null,"resizable,scrollbars");
setTimeout("pdf.close()", 2000);
}

Please clarify, or help... and many thanks!

Generally it would not matter that the code that attempted to close a
window was in the same script or function or not. If the window was not
opened with a script it should not be possible to close it with a script.

But the biggest issue with opening new windows is that pop-up blocking
may prevent them opening at all, so the ability to close them or not is a
relatively insignificant side issue in terms of designing for the
Internet.

And this is as far as I've got, but no success:

Making "no success" the extent of your explanation of what your code
actually does will tend not to get you any useful help.

function window(url) {
var pdf = window.open (url,null,"resizable,scrollbars");
setTimeout("pdf.close()", 2000);
}

The string values provided as the first argument to - setTimeout - are
evaluated in the global execution context, and your - pdf - is declared
as a local variable, and so probably unknown in the global execution
context.

Do not use the word window,
as this is reserved for your subsequent use.

2
pdf is not globally defined,
so not available to the timeout execution

3
Two seconds is a short time
to set up a window far inough to remove it again

try:

<script type='text/javascript'>
var w;

function doit(url) {
w = window.open(url);
setTimeout( 'w.close()', 15000);
};

</script>

<button onclick='doit("http://cnn.com/")'>
cnn</button>

1. "window" is a reserved word. Use a different variable, such as
myNewWindow.

2. The syntax for using setTimeout is:

var junk = setTimeout("pdf.close()", 2000);

The OP's syntax is fine. If you're never going to use the variable
"junk", you simply discard the returned value by not assigning it to
a variable.

@Richard
"no success" - yes, window opens, but never closes, so (my)
pop-up blocker is not involved. Have to verify once it works here.

@Evertjan, Jim
- window() is translation issue - original here is German fenster()
- pdf now is global variable, but no improvement
- time not yet relevant, since pertaining pdf's are local

In the meantime I exchanged posts in the German d.c.l.javascript
NG too, with "no success" again. But then we found out that may be
the pdf reader Foxit I prefer is the culprit. The script as is works
with Foxit and any local *.htm and any http://.., but not with *.pdf.

Looks like I have to revert to the Adobe Reader.
I'll find out and let you know.

Thanks and regards

The danger of code translation ;-(

Did you try my CNN code, it worked fine overhere!!

You cannot know that for certain, till you have a working example.

pdf's ??

It could be that a pdf window cannot be closed by the originating
javascript in some browser/reader combinations.

First try an html page.

As I said proviously, any http://... opens correctly -
in Firefox or IE7 that is, and closes after 15secs.

...
pdf's ??

Meaning pdf-files, geared to Foxit or Adobe Reader.

In the meantime, I installed the monster Adobe Reader,
but didn't get clear with it and sincerely hope to be
able to revert to Foxit.

I sent a support request to the Foxit people and wait
for an answer - and hopefully solution.

var w;

};

why are you using a string as the first parameter and defining the w
globally. what is wrong with this -

function doit(url) {
var w = window.open(url);
setTimeout( function(){ w.close() }, 15000);
};

Because some browsers are not able to do without it.

and defining the w

because, as I said, in the standard way of using setTimeout,
a local scoped variable w will not be available anymore.

what is wrong with this -

function doit(url) {
var w = window.open(url);
setTimeout( function(){ w.close() }, 15000);
};

Nothing, should it be "wrong" in your view?

Did you test it cross browser?

Personally, no I can't : no IE ...

Will or will not IE close the window 'w' ?
