IT3215 Introduction to JavaScript

Unit 1 Discussion

DQ1 Getting Started With JavaScript

JavaScript has been one of the most popular scripting languages for dynamic interactivity. It is a completely different language from HTML5 and CSS3, and it can be challenging for those without programming experience to begin. Research and describe some tips for someone new to JavaScript to get started. In particular, focus on at least two of the following points while providing sample code (with comments) for each:

Explain how different browsers handle JavaScript code. What considerations must be made when developing for different browsers?

Describe the use of JavaScript comments, including the process of "commenting out" portions of JavaScript code.

Explain the primary rules for creating a JavaScript identifier.

Explain the use of variable declarations and assignment statements with numeric, string, and Boolean data.

Explain the syntax for referring to a method or property of an object.

Explain the issue of cross-browser compatibility as it relates to JavaScript code.

Describe the creation and use of event handlers, including an event handler for the load event of the window object and how the HTML and JavaScript sections work together using the DOM.

Describe how the process flow for form submissions works between HTML, JavaScript, and a server-side language like PHP.

DQ2 Challenges to Using Variables in a Form

Note: The second discussion in each unit of this course is dedicated to community sharing of challenges and solutions encountered while completing your Unitly assignment. You are encouraged to post and respond early in theUnit to share experiences that you are having, and to help others with theirs. This is how coders solve tough issues: they rely on one another!

Creating and employing variables for the first time can be tricky. Putting them in a form can make it even tougher. For some it is very intuitive; for others, less so.

Discuss one or more of the challenges or experiences that you encountered when trying to complete this Unit's assignment. How did you try to address it or solve it?
