Interactivity with JavaScript

Cours 3 sur 5 dans Specialization Web Design for Everybody (Basics of Web Development and Coding)

If you want to take your website to the next level, the ability to incorporate interactivity is a must. But adding some of these types of capabilities requires a stronger programming language than HTML5 or CSS3, and JavaScript can provide just what you need. With just a basic understanding of the language, you can create a page that will react to common events such as page loads, mouse clicks & movements, and even keyboard input. This course will introduce you to the basics of the JavaScript language. We will cover concepts such as variables, looping, functions, and even a little bit about debugging tools. You will understand how the Document Object Model (DOM) is used by JavaScript to identify and modify specific parts of your page. After the course, learners will be able to react to DOM Events and dynamically alter the contents and style of their page. The class will culminate in a final project - the creation of an interactive HTML5 form that accepts and verifies input. This is the third course in the Web Design For Everybody specialization. A basic understanding of HTML and CSS is expected when you enroll in this class. Additional courses focus on enhancing the styling with responsive design and completing a capstone project.

Week Four: Validating Form Data

This week we will put a number of the concepts from this course together to tackle a new project - creating and validating input entered into an HTML5 form. Forms are extremely common elements used to input and send data to via a webpage. We will look at how you can use JavaScript to add options to your forms, to pre-fill data based on previous input, and even to check that passwords match.

Hey everybody,

congratulations on finishing the Interactivity with JavaScript course.

I hope you're really proud of what you've done so far, and

excited to keep learning more.

However, I do want to warn you right now that what we've covered in this class,

you're still considered what we call a noob or newbie.

So in order to really advance your skills, you're going to need to keep working.

But the good news is is that learning the basics of any programming language,

whether it's Python, JavaScript, some other type of scripting language.

Is that it makes you feel like you've really done something

that can last a long time.

And it's true because these different concepts of variables, arrays,

functions, and looping, these are concepts that repeat everywhere else.

So now that you've just begun programming,

you'll find that learning new languages is actually easier.

Now, we've done a lot of client side processing.

So I just wanna talk to you one more time about the idea that

what we've learned in this course is really only part of the picture.

Learning about server side code, or kind of hardcore programming,

is something that you'll need to explore on your own in other courses

if you decide that the coding part is what you really enjoy of web design.

This full stack or back end programming, they can help you with this, but it does

require additional resources beyond what most people find on their laptop or phone.

So, what should you do next then?

Well, I hope you continue to practice your skills, because unlike HTML,

and CSS, and some other components of web design, with JavaScript,

if you don't use it, you're absolutely going to lose it.

You lose these ideas.

You forget about checking the console.

You forget about the logical errors you made earlier.

What you can do now, if you wanna make sure you're still keeping your skills

sharp, is think about joining a meet up, or

offering your skills as a TA at different workshops.

You might also want to consider learning jQuery.

jQuery is an extremely powerful and

popular programming language that's built up from the basics of JavaScript.

However, I always encourage my students to understand just at least

the nuances of JavaScript before you jump into jQuery because it can make

your learning curve so much easier.

Of course, the other thing I must mention is that if you want to do more,

I hope you'll join us in our Responsive Design course that we're doing in this web

development for everybody's specialization.

So whether you're done and you hope to never code again, or

you're really excited and you wanna do more.

I can't say anything else but thank you for joining me in this course.

And thank you to everyone who was on the message boards mentoring each other and

encouraging each other.

Good luck.
