Access a window by window name
If I open a window using
window.open('myurl.html', 'windowname', 'width=100,height=100');
How do I refer to the new window (from the same page that opened it) using 'windowname'? This question is specifically about this. I'm aware that I could save a reference to the handle by using "var mywin = window.open(...)" but I don't care about that in this situation.
Thanks, - Dave
window.open()
-1 for not reading Daves question.
var mywin=window.open() is exactly, what Dave doesn't care about.– HBublitz

var mywin=window.open()
I am not sure I understand the question... You are saying you want a way to reference a window that you open from the opener, but then saying you don't care about how to do it?

@Dave: The accepted answer is simply incorrect, see Petr's answer.

afaik there's no way like windows['windowname'].
The 'windowname' assigned in window.open() can be addressed as a target in <a target="windowname" [...] >
windows['windowname']
<a target="windowname" [...] >
This is simply incorrect.

This shouldn't be the answer. See Jack Allan's link in the question's comments.

If you didn't save a reference to the window then there is no way to restore it. However, if that window is still open and if the page loaded there belongs to the same domain as your page, you can run JavaScript code in it:
window.open("javascript:doSomething()", "windowname");
Whether that's sufficient in your scenario depends on what you are trying to achieve.
Ugh. Even if that works.. i hope nobody really uses it. But I wonder if something like
window.open("javascript:void(window.opener.windowname = window);", "windowname") would work... that would do exactly what the guy asked for (not than anyone should actually use such a hack)– ThiefMaster♦

window.open("javascript:void(window.opener.windowname = window);", "windowname")
@ThiefMaster, I thought this was a rather elegant solution (assuming that it actually works). What is your objection to it, exactly?

It's a hack for a self-made problem - at least I can't imagine a reason why it would be impossible to store the window reference. You can always do something like
wins['foo'] = window.open('...', 'foo'); giving you access to a name-to-window-object mapping througt the global var wins`– ThiefMaster♦

wins['foo'] = window.open('...', 'foo');
var
@ThiefMaster: Usually the problem is that the opening window navigates to a different page so keeping the reference is impossible. Still, I agree - this isn't a great solution.

In firefox (might work in other browsers too, but now it's not my concern) I was able to reference one window accross multiple page loads with
var w = window.open("", "nameofwindow");
This opens new window if it doesn't exist and return reference to existing window if it does exist without changing contents of the window.
With jQuery I was then able to append new content, to make quick collection of interresting links like this
$('body', w.document).append(link_tag);
Petr is correct:
var w = window.open("", "nameofwindow");
works in all browsers, I am using it to retrieve the reference to the window object previously opened by a different page. The only problem is the initial opening of the page, if the popup does not exist, you will get a new window with a blank page.
I tried invoking a Javascript function inside the context of the other document in order to check whether I opened a new window or retrieved the already active page. If the check fails, I just invoke window.open again to actually load my popup content:
var w = window.open("http://mydomain.com/myPopup", "nameofwindow");
Hope that helps.

Doesn't work in Chrome: bugs.chromium.org/p/chromium/issues/detail?id=50513

Correction to above - it only works if the calling window opened the window you're trying to access, which is part of the question. Sorry about that, you are correct.

It is not possible. The windowName is just to be used in target="..." of links/forms or to use the same name again in another window.open call to open a new url in that window.
target="..."
window.open
and you gave exact same solution

Try open that window with the name, but URL is '' again, to check if it's a blank window or not. If it's in open, then you will get the window; if not, a new window open, and you need close it.
Add the children in localStorage will help to prevent to open the new blank window.

Assign the return value of
window.open()to a variable. This is the only proper solution.– ThiefMaster♦
