About JavaScript
What is JavaScript? JavaScript is a scripting language developed by
Netscape that runs in your browser that can add dynamic and programmable functionality to
Web sites. There are settings in your browser that allow you to control whether or not your
browser allows JavaScript to be processed.
What is JavaScript used for? Web sites developers often add JavaScript to
their pages to make them more dynamic and interactive. Another common use of JavaScript is
to validate information and alert you when incorrect information is entered.
Why is JavaScript important? Many Web sites cannot work properly if JavaScript
is disabled. Web sites that have sophisticated applications or dynamic features rely heavily
on JavaScript and may not work if JavaScript is disabled.
Is JavaScript safe? If you are on a Web site that you know and trust,
then in most cases there is no reason to be concerned about JavaScript. However,
other untrustworthy Web sites can use JavaScript to create things like pop-up ads
and spawn more browser windows.
How do I change my JavaScript settings?
To change your JavaScript settings, open a browser window. Under the Tools menu,
select Options, and then select Web Features.
Select Enable JavaScript. For more detailed JavaScript settings,
click Advanced.
