Script Writing

As the Web has evolved into a more robust environment, there is an increased need for Web site designers to control more of the presentation of the site. In the past, interactive sites were accomplished by using simple forms and passing data from those forms to applications that ran on the Web server. The results could then be generated by an application developed in a programming language such as C, Perl, or even Visual Basic. With more current Web sites, however, it is not uncommon to find yourself truly interacting with the Web page because of advancements such as Java applets, plug-ins, or ActiveX controls such as Flash, as well as the onslaught of Dynamic HTML.

Even though the use of simple forms is still appropriate today for accessing databases or other large or diverse information sources on a server, it is not effective for more simple actions such as verifying that the user input data into a field. This is not the optimal platform for simple field validation because each time the user submits data from a form, the information must be passed up to a Web server. There an application reads the data passed from the browser, performs actions such as checking that the fields are filled, and returns an appropriate message. In a world where connectivity to the Internet is not that quick, this can be a painful experience for the end user. Also, it is not quite intuitive to the user for another Web page to appear and state the errors on a previous page. In the world of Windows, the user would expect and prefer a warning message that does not interfere with their data input.
