JavaScript, Part 6 of 6: Objects

Course description

Objects in JavaScript 1.8 cover a wide variety of different items. This course will start with how to work with timers using the Window object. Next, you will learn to use the Location object to get page information and navigate to other pages. Finally, it will cover how to create and use windows programmatically.

Each LearnNowOnline training course is made up of Modules (typically an hour in length). Within each module there are Topics (typically 15-30 minutes each) and Subtopics (typically 2-5 minutes each). There is a Post Exam for each Module that must be passed with a score of 70% or higher to successfully and fully complete the course.

Prerequisites

This course assumes that you have at least some programming experience in one or more modern programming languages. JavaScript will be particularly easy for you to learn if you have experience with any C-style languages – including Java, C# C++ or Visual Basic .NET would be helpful – but this is not required. The focus here is not on programming concepts but on the structure, syntax, and use of the JavaScript language. You should also have some basic familiarity with how to build Web pages using HTML (we’ll use HTML5 in this course, but you’ll be good if you’ve used HTML4 or XHMTL), Cascading Style Sheets (CSS), and other standard Web technologies.
