Java Script

JavaScript

Other than the name, there is little similarity between Javascript and Java. Rather than a programming language, javascript is a scripting language, in much the same way that VB Script is.

Javascripts are used to add numerous interactive functions to web pages. Javascript can be utilised for a wide range of design activity from rollovers; to drop-down menus; to checking the contents of a submitted web form. [1]

A type of programming which can add interactivity and function to a web site. Some examples include drop down menus navigation button effects, interactive forms, slide shows, and pop open windows. There are many applications available to enrich a web site. [8]

A scripting language developed by Netscape to enable Web authors to design interactive sites. Although it shares many of the features and structures of the full Java language, it was developed independently. Javascript can interact with HTML source code, enabling Web authors to spice up their sites with dynamic content. JavaScript is endorsed by a number of software companies and is an open language that anyone can use without purchasing a license. It is supported by recent browsers from Netscape and Microsoft, though Internet Explorer supports only a subset, which Microsoft calls Jscript. [2]

JavaScript is a client-side scripting language. It is often used to supplement the standard web browser GUI elements (such as pulldown menus, check boxes and buttons) to create more sophisticated interfaces, for example:

  • Navigation roll-overs
  • Drop-down and fly-out menus
  • Customising and controlling (new) browser windows (pop-up windows)
  • Checking content before allowing a user to submit a form (validation)
