A script that opens a secondary window with the size adjusted relative to the screen resolution of the surfer. You can specify, for example, that the secondary window always be 50 pixels smaller than the screen of the surfer, regardless of the screen size of the surfer.
Animated Window
Opener
Opens a secondary window that expands to cover the entire screen before loading the
specified document into it.
Requires IE
4.x or NS 4.x to see the effect (although all other browsers will still open the secondary
window.
Break-out-of-frames script
This script detects if your page is trapped inside someone else's frames, and
automatically breaks out of it! We use it on the frontpage of JavaScript Kit to avoid entrapment by another site.
Channel mode window Opener
Opens up a window in channel mode (with the IE
channel strip appearing on the left). Requires IE 4.x, although all other browsers will
still open a window.
Close window
button
For some reason, this is one of the most requested
items we get script wise. It's a close window button that, well, closes the containing
window when clicked on. Comes in two flavors- a form button, or regular text link.
Customizable second window
This cool script will allow users to open a secondary,
customizable second window.
FairWell window launcher
I got the idea for the following script from a site I
recently visited. When I left, a cute little window popped up, thanking me for visiting
their site, and urging me to come back real soon. The window actually made an impact on
me, surprisingly. Here is a script that does just that- pops up a small, toolbarless
window as the surfer leaves the page. To avoid
over-irritating your surfers, the script comes with the added feature of only popping up
the first time the surfer enters and leaves the page.
Full Window Opener
Opens up a window that spans every inch of the screen. Requires IE 4.x, although
all other browser will still open a window in "normal" full screen mode.
Internal scrollable 2nd window
Loads up a second pop up window that contains an internal scrollable section
(Requires NS4.x)
Keep-in-frames
script
If your
site uses a frames setup, you probably do not want the containing pages to
be accessed individually. This script ensures they are not.
Left-To-Right
Scrolling Window
An alternate version of the above scrolling window script that scrolls the window
from left to right, and over again.
Pop-under
window
Pop-under windows are becoming
increasing popular as a less intrusive alternative to popup windows. Use
this script to add a pop-under window to your page; simply input the
page/address to pop under, and off you go!
Pop-under
window II
This
second version of the Pop-under window script randomly selects from a pool of
URLs to load in the pop under window.
"Regular" full
screen window Opener
Opens up a window in regular full screen mode,
with only the title bar present.
Scrolling Window
A scrolling window script that automatically scrolls the
window all the way to the bottom of the document, then starts all over again. Great for
presentational web pages.
Time controlled Popunder window 
This versatile popunder window script
allows you to precisely control how often the window pops under, in
terms of "once every x hours". For example, specifying 24 hours
translates into the script popping under only once a day.
Window Mover
Opens up a second small window and moves the window around in a circular fashion.
(Requires NS 4.x)
Window remote control
A remote control that loads links into the main window.
