After completing this course, students will know how to:

Define VBScript and describe the advantages of using it in your Web pages.
Embed VBScript code in an HTML document, hide the VBScript code from browsers that lack a VBScript interpreter, and insert comments into your VBScript code.
Define variables, name them appropriately, and demonstrate implicit and explicit declarations of variables.
Declare arrays and use them in your scripts.
Use the four types of VBScript operators and produce specific results by demonstrating their precedence.
Insert functions, subroutines, and Event Procedures into your VBScripts and reduce your programming effort by using VBScript?s predefined procedures.
Write code that makes decisions based on existing conditions, using control structures and loops.
Manipulate the variant subtype String, using some predefined functions. You will also be able to format numbers.
Enable communication with your Web page visitors using Message and Input boxes.
Extract date and time information from the client computer, format it and display the date and time of the last update on your Web page.
Use the DOM to control the layout of HTML pages, add effects, and get information from users.
Use functions to handle Windows mouse and keyboard events, validate user input, and handle run-time errors.

Prerequisites

A working knowledge of HTML is required for completing this course. Knowledge
