Introduction to JavaScript

The JavaScript client-side technology provides many advantages over traditional CGI Server-side scripts.

Introduction to JavaScript:

 

On December 4, 1995, Netscape and Sun Inc. jointly introduced JavaScript 1.0. JavaScript had truly bridged the gap between the simple world of HTML and the more complex Common Gateway Interface (CGI) programs on the Server. It provides a common scripting language for Web developers to design, test and deploy Internet Applications.

The JavaScript client-side technology provides many advantages over traditional CGI Server-side scripts. For example, JavaScript code can be used to check if the user has entered a valid e-mail address in a form field. The JavaScript code is executed when the user click Submit button in the form, and only if all the entries are valid, they would be submitted to the Web Server.
