enabling and disabling

The interwebs doesn't need any more step-by-step guides to enabling-and-disabling. So, rather than re-invent the wheel, here's a couple of links to two of the best

Please note: it is possible that, even with javascript enabled in your browser, you still won't be able to access 'missing' features, content and/or functionality

The two most common reasons for this happening are:

• your machine might be behind a firewall that is over-riding your settings
  
  
• downloaded security patches might have altered your javascript settings
  
  

a couple of well-written guides to enabling javascript

• Mr. Ed's Computer Help Forum
  
  
• Google AdSense Help Center
  
  

if that's too complicated

• simply upgrade to the latest version of any one of the following browsers
  
             
  
  scripts are usually enabled by default

blocking scripts on a site-by-site basis

The easiest way to block javascript (permanently or temporarily) on a site-by-site basis is to use a Mozilla browser (Firefox, Netscape or Flock) with the NoScript add-on, which is - as per all the best things in life - free to download, easy to install and very simple to use

ugly use of javascript

Unfortunately, JavaScript is often misused to create what JavaScript expert Douglas Crockford calls evil script

If evil script gets onto a page from a good site, the evil script can access the server and there is no way that the server can see that it is talking to an evil script. The script also gets control of the screen, and the user is also unaware of that. This is known as the XSS attack.

If you happen to land on an evil page, script on that page can access servers that you have visited (such as your bank's website), and again, the server cannot tell that it is talking to an evil script. This is known as the XSRF attack.

Derby Web Devlopment use of javascript

On web sites written and maintained by Derby Web Devlopment, javascript is only used to:

• validate user input, such as making sure that contact names, subject lines, messages and valid email addresses are supplied before an email is submitted via a contact form
  
  
• display non-essential  features
  
  such as
  • displaying email addresses
    
    
  • random quotes
    
    

usability, accessibility and functionality

Because they're more than just 'buzz words' (they are - literally - vital for the success of any site)

• scripts are accompanied by <noscript> messages, which explain (to visitors with scripts disabled) what is 'missing' and how to see it.
  
  
• All scripts are tested using Scryptik - The javascript Editor
