JavaScript Mini-Project
Add real interactivity to your HTML/CSS website. Your JavaScript should fit your site’s topic and give the user something they can do.
What You Will Make
Create at least one meaningful interactive feature on your website. Your feature must use your own JavaScript code (not just examples copied verbatim). The interactivity should relate to your site’s purpose.
Examples of Possible Features
- Buttons that change text, pictures, or styles
- A section that shows more / shows less when clicked
- Small personality quiz or multi-step interaction
- Clickable thumbnails that show a larger picture
- A content box that updates based on user choices
- A calculator or tool related to your topic
- A simple slideshow with next / previous buttons
- A small text-processing feature (modify user input)
- A form with basic checks before submitting
- Local storage used to remember a preference
These are suggestions, not requirements. Your idea just needs to be doable within the project window.
Required JavaScript Skills
Your project must show these basic techniques:
- document.getElementById() to find an element
- At least one event trigger (onclick, onchange, etc.)
- At least one function you write yourself
- At least one meaningful update: innerHTML, value, src, or style
Proficiency Scale (combined standards)
Level 4: Your feature meaningfully improves the site and shows strong programming skill. Code uses multiple concepts together (variables, if/else, arrays, simple loops, functions). Refinement is evident. May include a small external library or built-in browser feature (localStorage, basic animation, etc.). Code is clearly your own and organized logically.
Level 3: Your JavaScript fits the site’s topic and works reliably. Code uses getElementById, at least one function, and an event trigger. Logic goes beyond a single one-step change. The interactivity clearly belongs on this website and responds to user actions in a useful or interesting way.
Level 2: Your page uses JavaScript to let the user interact, but the interaction is simple. Code demonstrates basic understanding of finding elements and updating text, images, or styles.
Level 1: JavaScript is included but shows only minimal understanding. Code is very close to provided examples and not meaningfully adapted for the website’s topic.
Level 0: Not enough evidence. Broken code, copied code without understanding, or no JavaScript included.
Tips for Choosing a Good Project
Pick something small but expandable. A simple idea can reach Level 4 if it is done cleanly, refined, and uses thoughtful programming structure. Large ideas are welcome but not required. The focus is on understanding and applying the JavaScript concepts from this unit.
Project Ideas (Choose One)
Pick an idea that fits your site’s topic and is doable in the time you have.
Change Text or Content Based on User Choices
- Buttons that switch between different text sections
- A “show more / show less” content box
- A preview window that shows content when items are clicked or hovered over
- A small personality quiz with 3–6 questions
- A title or caption that updates when the user picks an option
Work With Pictures
- Click a small picture to show a larger one
- Toggle between two images (before/after, day/night, etc.)
- Mini slideshow with next / previous buttons
- Hover to change an image or reveal a caption
Interact With User Input
- Read text from an input box and display a result
- Modify what the user typed (e.g., format it, check it, convert it)
- A small topic-related calculator (grading, cost, stats, etc.)
- A short survey that shows results on the page
Change Style or Layout
- Theme switcher (light/dark mode)
- Buttons that change color schemes or highlight sections
- Reveal hidden steps or hints in a tutorial
- Animate something with simple style changes
Use a Small External Feature (Optional)
- Store a preference using localStorage (remember a theme or username)
- Use a small animation library like animate.css
- Display icons or images using a class selector
Mini Online Store (Mockup)
- Page shows several products (images + names + prices)
- Buttons add items to a “cart count” or “cart total” displayed on the page
- Optional: a simple “remove item” button that subtracts from the total
- Optional: save the cart total using localStorage
Image Gallery / Photo Viewer
- Grid of thumbnails → clicking shows a large version
- Next / previous buttons to navigate
- Optional: slideshow mode that changes images automatically
Choose-Your-Path Story
- User makes choices (buttons) that show different text sections
- Use arrays to organize story steps
- Optional: track “inventory” or “points” with variables
Mini Games (Very Simple)
- Rock–Paper–Scissors
- Guess-the-number with hints
- Matching pairs (reveal/hide images)
- Dice roller or randomizer for a topic (e.g., “Which recipe should I try?”)
Topic-Based Tools
- Budget calculator for a travel-themed site
- Character creator for a fandom site (pick traits → display result)
- Workout planner or randomizer for a fitness site
- Study flashcards with next / previous and “reveal answer”
Interactive Guides or Tutorials
- Reveal steps one at a time (math steps, craft instructions, etc.)
- Buttons that highlight key parts of an image
- “Check your answer” boxes for practice problems
