A Web specific language designed by Netscape, Javascript (a.k.a. DHTML) makes Web pages interactive to users. It is not a counter part to the Java language but it does share some of the same features and structures. It was developed independently of Java. It is open source code meaning that anyone has the right to code with it without the need for a license. Javascript is specifically designed to be embedded into HTML code and executed through calls from the source code. Here are some specific uses for Javascript:

  • Generate dynamic text into an HTML page
  • Respond to a user initiated events on Web pages
  • Ability to read and write HTML elements
  • Validate or manipulate data such as input on a form

There are ADA - Web Accessibility issues that need to be addressed when implementing Javascript functionality on Web page. Please review the Web AIM article on Keyboard Accessibility to understand how to implement Javascript and while providing accessible Web pages. The key is to ensure that all content can be accessed with the keyboard alone.

Please refer to W3Schools for information on how to implement Javascript into your pages
