VBScript Introduction Course

Upon completion of this course, the participant will be able to:
> Define VBScript and describe the advantages of using it in Web pages
> Embed VBScript code in an HTML document, hide the VBScript code from browsers that lack a VBScript interpreter, and insert comments into VBScript code
> Define variables, name them appropriately, and demonstrate implicit and explicit declarations of variables
> Declare arrays and use them in scripts
> Use the four types of VBScript operators and produce specific results by demonstrating their precedence
> Insert functions, subroutines, and Event Procedures into VBScripts and reduce programming effort by using VBScript’s predefined procedures
> Write code that makes decisions based on existing conditions using control structures and loops
> Format numbers and manipulate the variant subtype String, using some predefined functions
> Enable communication with 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 the 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
