Advanced JavaScript Programming

Course length:
2 days

Course description

Overview: Students who are already familiar with the fundamentals of JavaScript programming will learn how to develop scripts that are modular, easily maintainable, and compatible with multiple browsers. Students will learn debugging techniques and how to use advanced programming features such as custom objects, arrays, and cookies. Students will also learn how JavaScript communicates with other software such as applets and server-side scripts.

Prerequisites: JavaScript Programming or equivalent knowledge.

Delivery method: Instructor-led, group-paced, classroom-delivery (or distance learn) learning model with structured hands-on activities.

Benefits: Students will learn how to use advanced JavaScript programming features and techniques to enhance their use of JavaScript in developing Web pages.

Target student: Students enrolling in this course should understand basic JavaScript programming. For example, students should already know how to write and call a simple JavaScript function.

Performance-based objectives

Lesson objectives help students become comfortable with the course, and also provide a means to evaluate learning. Upon successful completion of this course, students will be able to:

• Debug and maintain JavaScript code libraries.
• Develop Web pages that display different content or execute different code based on the version of JavaScript that is present on the Web client.
• Create custom objects with custom methods and properties.
• Create, read to, write from, and delete single and multi-dimensional arrays.
• Store, retrieve, and delete cookies.
• Write JavaScript code to communicate with Java applets, ShockWave movies, ActiveX controls, and server applications.
