newbie's popup code question

[newbiegalore]

Hi everyone ,
I searched the forum to look for an answer to
my query but did not find a match. I'm trying to write a small script
which would be able to identify whether a site is using pop ups or
not. Could someone please let me have a pointer as to what I should be
looking for in the code?

Looking for tags like <SCRIPT LANGUAGE="JavaScript">, and for
function, window.open, onload might be able to tell me that the site
used popups. Is there a better way to to do this. If anyone knows of a
tool/script which can identify popup code inside the HTML source,I
would greatly appreciate any info about it.

Thanks in advance,
-A

No need to look for <script> as the code doesn't have to be in a script
block. onclick="window.open(this.href)" in a link is one example.

Searching for window.open may not suffice either as you can break up the
call by assigning a reference to window and then using winRef.open or
they could be using window['open']('someURL')

So then if there are a large number of ways to "obfuscate" the call to
make a new window, is there a common call which all of these
approaches make? I mean that if they all call a window-open event or
use a library to do so can I detect it using ld? Sorry if my question
seems a bit lame..I'm an absolute n00b with JS.

What's the generic way for a pop-up blocker to understand that a pop-
up is trying to open up?

Thanks.

Any of them are going to try to intercept a call to window.open,
determine if it was user initiated or not, and let the call be issued.
Some of the more aggressive blockers simply redefine the window.open
method and make it impossible to open a new window. Some are capable of
intercepting target="new_window" type attributes on links and force it
into the current window.

All what you have to know is that visitors can have fixed their
navigator to open a html blank window or a JS popup in :
- another tab (with/without jupping to it)
or
- same window (same tab)
and some bad popup's blockers could display nothing.

If you however use window.open(); have a look here :
<http://developer.mozilla.org/en/docs/DOM:window.open>
<http://developer.mozilla.org/en/docs/DOM:window.open#FAQ>
<http://www.gtalbot.org/DHTMLSection/WindowEventsNS6.html>
and don't resize (nor size) your popup since it can be in the main window.

It's why we see now most of advertisements appearing in false-windows
somewhere in front of the displayed page in same window.
