Please watch this first.

In this video we meet our instructor for the course, Mark Lassoff.  We also get introduced to the major server side and client side languages that are used on the web.  Mark also gives some background some background about HTML and CSS-- the other client side langauges that are used to create web sites.  Finally Mark gives a more detailed background of the Javascript programming language. 

This set of slides have information about the course, the instructor and how to succeed in the course.  

In this video youi and Mark will create your first Javascript program.  Mark will explain what software you need to create Javascript (not much!) and how to go about creating yoiur first Javascript program and executing it in the browser.

In this video Mark introduces you to the three locations where you can embed Javascript code-- In the document , in the document and as an external attached file using the src attribute.  Mark will also provide a quick introduction to using Javascript functions which will be covered thoroughly later in the course.

These are the code examples used in lecture for chapter 1.  Open these and examine them carefully to help you understand the concepts that Mark discussed in the lectures!

In this video lecture, Mark discusses using variables in Javascript.  Mark will demonstrate how to use string variables and variables that carry numerical values.  Variable declaration with var and variable initialization will be demonstrated. Mark will also demonstrate how to output variable values using document.write().

In working with variables you will use variable operators.  In this video, Mark discusses the mathamatical operators used with variables.  He also discusses the concatenation operators used with string variables.

These are the code files that Mark used in the lecture.  Download these files and examine them to become more familiar with the concepts discussed during the lecture.

In this video lecture, Mark demonstrates the use of simple conditional statements.  Using the if statement your Javascript programs can make decisions based on program conditions and execute specific code bsaed on those decisions.  Mark reviews the conditional operators and also creates compound conditionals in this lecture.

Mark reviews the use of else and else if in this video lecture.  You'll learn how to write conditionals that can execute a block of code if the condition is evaluated as true and another block of code if the conditional is evaluated as false.

In this Javascript video, Mark introduces the switch... case... break conditional statement which allows you to evaluate a number of conditions in an efficient manner.

These are the example files that Mark created during the Chapter 3 lectures.

In this video lecture, Mark will demonstrate the three kinds of dialog boxes available in Javascript.  Mark will demonstrate the alert() box, the confirm() box and the prompt() box.  With the latter two dialogs, Mark will also demonstrate how to capture the users response to the dialog box and process that information.

This is the HTML file that Mark created during the lecture.  Study this file carefully to learn to code the three types of dialogs available in Javascript.

In this video lecture Mark covers two common types of loops:  While loops and Do...While Loops.  Loops allow you to execute a block of code a number of times.  This is useful if you need a portion of the code to be repeated during execution-- as you might during a game such as Poker or Bingo.  First Mark discusses While Loops and then the Do...While Loops.

In this video lecture Mark will show you how to use the compact and efficient for loop.  He will also demonstrate a practical application of a loop as it is used to take several inputs from a user and output them using document.write.

In this short video lecture Mark gives you a hint that will help you complete number 5 in this section's lab exercises.  parseInt() and parseDouble() are covered.

After watching the video lectures complete these lab exercises. These lab exercises will help you to apply and retain the information presented in the lecture.

These are the code examples from the lectures in Chapter 5.

In this video lecture, Mark will show you the basics of functions in Javascript.  Mark will show you how to properly code both the function definition and the function call.

in this section Mark will demonstrate how to create more sophisticated functions that can take one or more arguments and can return a value to the caller.

In this video lecture Mark will show you how to call functions based on user interface events such as a button click or a web page loading into the browser.

Use this file to get started with the lab exercises as directed in the lab instructions PDF file.

These are the examples that Mark coded in lecture for Chapter 6.

In this video lecture Mark discusses the three methods of declaring an array in Javascript.  Mark also goes over looping through an array, changing the values within an array and accessing array memebers.

In this video lecture Mark continues the discussion of arrays.  Mark demonstrates what happens if you go beyond the array boundaries.  The for...in statement is discussed as well as the pop(), push() and sort() methods of the Array class.

These are the code examples that Mark created in the video lectures for Chapter 7.

In this video lecture, Mark discusses the string object.  Manipulating strings is an important Javascript task and is frequently necessary when Javascript is used for user input validation or to deal with HTML text.  Mark demonstrates the length property as well as several string methods in this video.

This is the HTML file that Mark creates during the video lecture for Chapter 8.

In this video lecture Mark will discuss how to get information about the user's environment.  Mark will show you how to obtain information about the user's browser, the user's screen and how to obtain and manipulate information about the browser's location.

This is the HTML file that Mark created during the video lecture.

In this video lecture, Mark introduces the document object.  The document object can be used to manipulate objects within the page.  Mark will show you how to access form fields and manipulate the style sheet dynamically in this video.

In this final video lecture, Mark discusses the innerHTML property.  The innerHTML property can be used to dynamically manipulate the HTMLin a document.

This is the HTML you need to start the lab exercises as discussed in the lab instructions.

These are the files that Mark created during the video lecture for Chapter 10.  Examine these files to better learn the code concepts demonstrated.
