Year 11 - Computing

JavaScript

HTML programming project

Unit Summary

In this unit pupils will explore how websites are displayed within a browser using HTML and CSS. They will examine how websites are requested and delivered to our computer via the internet and the WWW. They will create the structure of a website using HTML and change the styling using CSS.

Lesson Summary

You will learn to use JavaScript to add interactivity to a web page.

Key Notes

  • JavaScript can be used to change HTML content and styles dynamically to make web pages interactive.
  • The Document Object Model (DOM) allows JavaScript to access and modify web page elements.
  • Event listeners detect user actions (such as clicks and key presses) and trigger JavaScript functions.
  • Functions in JavaScript allow us to write reusable code that updates and responds to user interactions.

Vocabulary To Learn

  • JavaScript: a programming language used to add interactivity to web pages
  • DOM (Document Object Model): a representation of a web page that JavaScript can use to access and change HTML elements
  • event listener: a function that waits for a user action (such as a click) and then triggers a response

Common Mistakes To Avoid

  • JavaScript changes the original HTML file.
