Free code snippets for web pages
A combination of these scripts can be used to detect browser type
and better optimize page layout, detect and limit access to certain platforms and browser types, and even add limited copy protection to a web page.
Disable right click
The No-Right-Click snippet (disable right click) is written in
JavaScript and supported in all web browsers. It can be used to
obscure links, source code and hamper the saving of
images by disabling the right mouse button option.
No-Right-Click can be a deterrent to most web sites visitors
however it will only provide a mild annoyance to the more
proficient web surfer who can either disable JavaScript support
in their browser settings or simply save the whole web page.

Click script.
Disable drag & drop
Code snippet to disable drag & drop.
Drag'n'drop which describes the action of selecting an image on
a web page with the mouse, and then click dragging it to desk
top is one of the many methods available for copying images
from web pages. This code will prevent mouse dragging of images
from a web page onto the desk top. Click to download the No
Drag'n'drop script.
Disable printing
Preventing print is most difficult because there are many
different print options such as sending to a connected printer,
a virtual printer or network printer. However it is possible to
hamper printing. In most cases the site visitor will get a
blank page. Click to download the Disable Print script.
Disable Printscreen
JavaScript code snippet for disabling Printscreen. This
JavaScript will clear the clipboard repeatedly so that any
attempts to copy'n'paste or use the Printscreen will be
thwarted by replacing the clipboard with emptiness. Click to
download the Disable Printscreen script.
Disable screen capture
A code snippet on a web page cannot prevent screen capture.
There is absolutely nothing that JavaScript can do and nothing
that be used within Flash to prevent screen capture software
from taking screen shots. The only solution for the prevention
of screen capture is the CopySafe Runtime provided by
ArtistScope!
Detect web browser
and platform
Detecting what type of computer and browser is being used can
be most useful for redirections and it can be quite easy when
simplified. Generally detection scripts run into extensive
detail, most of which is rarely needed and if anything,
needless confusion. Broken down into the basic requirements
these scripts will be versatile and easy to use. Click to
download the Detect Browser script.
Detect cookies
If cookies aren't enabled then any sort of password/login
system will more than likely fail. Cookies can be detected
simply be setting a cookie and then trying to read it. If a
cookie for the site cannot be found then cookies are probably
not enabled. Click to download the Detect
Cookies script.
Detect JavaScript

JavaScript and then redirect to another web page. Click to
download the Detect JavaScript script.

and its version. The Java Version Applet will detect the
version and if it's not at least the version that you specify, the
JavaScript will redirect for a more recent download. Click to
download the Detect Java script.
Detect plug-in
Retrieving a list of plugins is one thing, but checking if a
certain plugin is in fact installed is another. This script
detects the platform and browser type and then uses the
appropriate code for either an ActiveX or Mozilla plug-in to
create an embedded object. Click to
download the Detect Plugin script.
