javascript:close() for tab in Firefox

petcancervet

I am writing a PHP/MySQL web-page based system on Firefox and wish to
run a separate page from an <Alink to run a separate PHP script,
then close that page. Firefox starts a new tab for this and it closes
OK but I am then left with an egg-timer at the mouse arrow when over
top or bottom toolbars areas of the parent page.

I am using <BODY onLoad='javascript:close()'to fire the tab closure.
I have tried opener.focus() with no effect.

I can't tell what is running. It doesn't happen with IE.

Any explanation/solution?

That is no valid eventhandler.
It is pseudoprotocol for <a href="javascript:...">
Never use it.

To get your onload handler working simply use:
<body onLoad="someFunction();">

and define someFunction() elsewhere.
You can also put the direct javascript commands into the onLoad handler.

IE sucks in its own way.

<body onload="self.close();">

What is the interest to load a page if it is to close it immediately ?

<body onload="setTimeout(self.close,200);">

Usually when the pop-up-tab is closed you come back to the opener tab.
There is no reason to get egg-timer nor wheel

What does the error console of Fx say ?

I have tried opener.focus() with no effect.

too late ?

Any explanation/solution?

what is supposed the "separate" php to do ?
can't it close the window (tab) itself ?
(instead of onload in body tag)
in opener try with your link :

<a href="page.php" target="other" onmouseup="this.blur();">
<a href="page.php"
onclick="window.open(this.href);this.blur();return false;">
and don't forget ..............................^^^^^^^^^^^^^

yes it is. in this case, javascript: is interpreted as a label. it's
just useless.

Hi,

OK, thanks for correcting that. I didn't know that.

Is there ANY use ever for javascript: ??
(I don't want to advise people to avoid it if it has actual use
somewhere/somehow.)

To be precise, it is not an event handler, valid or otherwise. It is the
value of an intrinsic *event handler attribute*. The value, which type is
CDATA, is supposed to be a string value representing code written in an
ECMAScript implementation here (because such a language appears to be the
default scripting language in past and current HTML UAs).

Whether `javascript:' constitutes syntactically valid ECMAScript-compliant
code depends on the implementation used: ECMAScript before Edition 3 did not
specify the LabelStatement production. So strictly speaking, it is e.g. not
valid (by any standards you want to apply) in Netscape before version 4.0,
and Microsoft Internet Explorer before version 4.0, because the ECMAScript
implementations they supported did not support that particular feature yet.

Yes.

1 In favelets/bookmarklets.

2 In an [IE only] vbscript using page, to call sporadic js:

========================
<script type='text/vbscript'>
document.write "Hello<br>"
i = 7
</script>

<div onclick = 'javascript:alert(++i);'>
Click me!

IIRC the purpose of the javascript: URLs (and URLs only) is to call a
JS function that returns the content of a page/image/whatever. IOW you
could use it to generate an image or page on the fly. Which won't work
for event handlers, since event attribute values aren't URLs.

For instance: <a href="javascript:'bla'">click</a>

It is described how it is supposed to work, and that appears to match the
implementations' behavior. I have posted the description in another thread
*today*, so there really is no need to post your wild assumptions.

A link to a description to how it's "supposed to work" would be
nice. It's unsurprisingly hard to search for this behaviour because of
the keywords involved.

Neither of the two pages you mention in that post is in the first 100
results on a google search of '"javascript url"' (with quotes) or
'javascript url' (without quotes) for me. And not to be annoying, but
it looks to me like those pages are describing browser behaviour as it
was whenever they were written instead of any kind of standard (not
that there's anything wrong with that).

Anyway, thanks.

Thanks, guys (& gals but I didn't notice any)

That got rather esoteric.

Just to be annoying I have rewritten the code using IFRAME instead!
The point with the PHP is that I have to fire code to set up a new
MySQL table but then return to the submitting page as it was.
Reloading PHP pages leads to very complicated if {}s and becomes
unintelligible.
