Web-page that *BOTH* changes current page + displays a Pop-up pagefrom JavaScript

J

John L.

I'm having trouble accomplishing the subject task in an HTML
JavaScript.

When I initially spec'd the function, I envisioned JavaScript source
with the following flow:

1) Create pop-up window via popupWindow = window.open(...)
2) Change current page via window.location.replace(URL)
3) Change focus to put pop-up window back on top via popupWindow.focus
()

I did not anticipate that my JavaScript would terminate upon the
completion of the method in #2 above. As a result, I have created a
pop-down window, hidden behind the new page.

Is there a methodology I can use to accomplish the desired task?

Thanks in advance for your time and consideration.

Of course it terminates -- where is the code to work on?

Doesn't work.

Yes. Let code in a.html open b.html in a "pop-up window" (could be anything
from the same window to a browser tab).

Then, in a.html:

<script type="text/javascript">
/* (1) */
var w;

function popup(sURL, sWindowName)
{
if (w && !w.closed && isMethod(w, "focus"))
{
w.focus();
}
else if (typeof window != "undefined" && isMethod(window, "open"))
{
w = window.open("b.html", sWindowName, "resizable,scrollbars");
}

return !w;
}
</script>

<a href="foo" onclick="return popup(this.href, 'bar')">...</a>

In b.html:

<head>
...
<script type="text/javascript">
function body_load(sURL)
{
if (typeof window == "undefined") return;

/* (2) */
var o = window.opener;
if (o && !o.closed && o.location && isMethod(o.location, "replace"))
{
o.location.replace(sURL);
}

/* (3) */
if (isMethod(window, "focus")) window.focus();
}
</script>
</head>

<body onload="body_load('foo')">
...
</body>

- The order of (2) and (3) may be reversed
- Doesn't work with different URI schemes, host names, or ports (man SOP).
- isMethod() is not a built-in; search for it.

I have a question that I've wanted to ask for a long time. Is there
any hack trick to ensure that IE7/8 will open a real new window rather
than a new tab *regardless* of the user's preference settings?

I have found a trick in Firefox. It is just a matter of choosing the
right window properties in the third argument to window.open. Some
combinations seem to force a new window to open, and others will open
a tab if that is the user's browser setting.

I think Chrome is like Firefox: some combinations of window properties
will force a real window to open. I cannot even find a preference
setting in Chrome to switch from "open popups in tabs" to "open popups
in window."

Safari always seems to open a new window when there is a call to
window.open.

If anyone has found any trick, especially for IE, I'd be interested to
know about it even if it is a hack.

Hey, this is *my* browser mate. I'll open stuff in a new window if *I* see
fit.

It's bad enough you are opening a new tab.

Maybe you should create a bug report (search for an existent one before). If
the user's settings forbid new windows and you can ignore this setting, it's
obviously a bug. Expect this to be fixed.

Yes, I do expect it to be fixed and I may log bug reports.

Regardless, my question still stands. Has anyone found a found a trick
that currently works to open a new window in IE7/8?

I think that is a very limited view of how a web page should be built.
At times a new tab or even a new window is appropriate to the benefit
of the user.

I agree that the user's browser preferences should be honoured;
however, I'm curious if there are any tricks for IE7/8 to force a new
window even when the user has chosen tabbed browsing.

Baloney. If you really believed that, you wouldn't ask this question:

What part of "the user has chosen" are you having difficulty understanding?

Persistant bastard, aren't you.

Your answer is: no.

Unlikely, and if there would be a way, that must be considered a bug to be
fixed soon; nothing to rely on. That is why they are called *user*
preferences. Of course, you can always deploy a IEAK-based Web application
where such restrictions might not apply.

The probability that a new window is opened instead of a new tab or the
document being loaded into the same tab, increases if you provide the
`width' and `height' parameters in the third argument of window.open().
Be sure to provide the `resizable' and `scrollbars' parameters also.

In addition, several user agents also have methods for dialog windows, e.g.
window.openDialog() in Gecko-based and window.showModalDialog() in both
Gecko-1.9+ and MSHTML-4.0+-based UAs.

<https://developer.mozilla.org/en/DOM/window.open>
<https://developer.mozilla.org/en/DOM/window.openDialog>
<https://developer.mozilla.org/en/DOM/Window.showModalDialog>
<http://msdn.microsoft.com/en-us/library/ms536759(VS.85).aspx>

With Internet Explorer 7+, be aware that if popup windows are blocked by
default, the user needs to reload the document in order to show the popup
eventually.

Script-kiddies rely on tricks to achieve what *they* want in spite of the
available evidence; responsible developers reconsider the design of their
application so that, within the capabilities of the UA, it suits the needs
of the *user* best.
