Learning JavaScript Events for Interactive Web Pages

Day 46/100 – Understanding JavaScript Events ⚡ Today I focused on learning how JavaScript events work and how user actions connect to functionality. JavaScript events allow us to run code when something happens on a webpage — like a click, keypress, or form submission. What I learned and practiced: ✔️ What events are and why they matter ✔️ Using addEventListener() ✔️ Handling click events on buttons ✔️ Connecting events to functions ✔️ Debugging event-related issues with console.log() Example: When a user clicks a button → An event is triggered → A function runs → The UI updates. Understanding this flow helped me see how interactive websites are built. Day by day, I’m getting more comfortable turning ideas into working features.

Day 2 of my JavaScript journey Today I explored CSS style manipulation using JavaScript and deepened my understanding of how the DOM works. I learned that to update content or properties in the DOM, we use the assignment operator (=). When modifying CSS styles through JavaScript, values must be written as strings and include appropriate units (e.g., "20px", "2rem"). I also learned that the dot (.) is used in querySelector() when selecting elements by their class name. Small concepts, big progress.. #JavaScriptJourney #LearningToCode

Doubling Down on JavaScript Mastery - Day 14 /60💪 Theory Day: DOM selection: the bridge between HTML and JavaScript. The Toolkit: • getElementById() – One ID. One element. Direct hit. • getElementsByTagName() – Grab every <p>, <button>, or <div> • getElementsByClassName() – Target by class, regardless of tag • querySelector() – CSS selectors. First match wins. • querySelectorAll() – Every match. Static snapshot. The Twist: Live collections update themselves. Static collections don't. Choose wrong, and your code behaves unexpectedly. Choose right, and you're in control. Master these, and you stop fighting the DOM. You start directing it. What's your most-used selector? 🎯 #JavaScript #WebDev #Coding #100DaysOfCode

💡 New Project: The Power of JavaScript I just built an interactive Light Switch — and this tiny project taught me a BIG lesson 👀💡 Here’s what’s happening behind the scenes: • Used addEventListener to turn the light ON/OFF • Swapped image src to show dark vs illuminated mode • Updated button colors to match the mood of the scene It’s honestly exciting to see how simple JavaScript logic can create such a cool visual effect ✨ 👉 Beginner-friendly projects like this make JavaScript click. If you’re learning JS too, comment JS and let’s grow together 👇 #JavaScript #WebDevelopment #LearningInPublic #StudentProject #WomenInTech

Built some cool stuff with HTML, CSS & JavaScript 👨💻🔥 Instead of just learning concepts, I focused on building mini projects to understand how things actually work. 🎯 This demo shows: – Real-time interactivity – JavaScript logic in action – Clean & simple UI 🚀 Live Demo: https://lnkd.in/gq48vQf5 📌 Code on GitHub (link in comments) Feedback is welcome! 😊 #ClearingDrafts #FrontendDevelopment #JavaScriptProjects #StudentDeveloper #GitHubPages

🚀 Learning JavaScript DOM Manipulation – Real Practice! Today I practiced JavaScript DOM manipulation by working with getElementById() and getElementsByTagName() to dynamically access and modify HTML elements. In this task, I: Created a simple HTML structure with multiple <p> tags Used JavaScript to select elements using their ID and tag name Extracted a specific paragraph value using index Updated the page content dynamically using innerHTML 💡 This helped me clearly understand: How JavaScript interacts with HTML How to access and manipulate multiple elements How dynamic content rendering works in real-time Here’s a small example of what I implemented: ✔ Accessing elements ✔ Reading values ✔ Displaying output dynamically Every small project improves logical thinking and frontend skills 💻✨

#CodvedaJourney, hashtag #CodvedaExperience #FutureWithCodveda #CodvedaTechnologies Level 1 Task 3 :Adding basic interactivity to a web page using JavaScript.. 💯 💡 Objectives: I created interactive elements like dropdowns and forms. I wrote basic JavaScript functions and event listeners and made use of validation form inputs using JavaScript. Find the live demo on my Github: https://lnkd.in/dw5WQMGr

Started with JavaScript fundamentals and I'm now advancing into in-depth JavaScript components and core concepts. Today, I studied the Document Object Model (DOM) and its properties, focusing on DOM manipulation and event handling. - What is DOM? It's a structured representation of HTML document. it allows JavaScript to access HTML elements and styles to manipulate. Basically, it is a connection point between HTML and JavaScript.

I got to learn about the DOM and how it actually works. One of the first things I picked up is that the DOM always starts with the document object, which is basically the gateway to everything on a web page, it's where you begin whenever you want to access or change anything on the page. I also discovered that methods like "getElementById" and "addEventListener" aren't part of JavaScript itself, they come from Web APIs. These Web APIs are like libraries that browsers provide, and JavaScript can access them to interact with the page. It was really interesting to see how JavaScript and the browser work together to make web pages dynamic.

JAVASCRIPT NOTES — PART 2 (Arrays • Objects • DOM) Foundations build clarity. Practice builds confidence. This post focuses on the parts of JavaScript that actually make web pages interactive: • Arrays and important methods (map, filter, reduce) • Objects and destructuring • DOM manipulation • Events and event propagation • this keyword & event delegation Understanding these concepts properly is where JavaScript starts feeling practical. Before async, before frameworks — this layer must be clear. 📌 Save this if you're strengthening your JS fundamentals. #JavaScript #WebDevelopment #FrontendDeveloper #LearningInPublic #InterviewPrep #StudentDeveloper #Consistency
