2.4. JavaScript
-
JavaScript (now standardised as
ECMAScript) can be used to script the contents of pages,
change their appearance, or control their various on-place widgets.
-
The implementation of JavaScript varies from browser to browser and sometimes
has many bugs. Use with care.
-
A general rule of the thumb is that your site should not depend on JavaScript.
-
Do not use JavaScript for linking to another page, changing the appearance of
a link on hover, generating HTML, or other things for which plain HTML
would do.
Examples for good uses of JavaScript
-
Form Validation and Automation at the browser's side. (which does not
preclude you from having sanity checks at the server).
-
Games. :-)
-
Navigation Menus. (again - the site should not depend on them).
More about it
-
I prepared a discussion of the pros and cons of using JavaScript in pages
one writes.
