Understanding DOM Manipulations in JavaScript 🌟 Today I explored DOM (Document Object Model) Manipulation — one of the most important concepts in web development! 💻 The DOM represents the structure of a webpage as a tree of HTML elements, allowing JavaScript to access, modify, and update content dynamically. Here are some key methods I learned: 🔹 getElementById() – Selects an element by its ID. 🔹 getElementsByClassName() – Selects all elements with a specific class. 🔹 getElementsByTagName() – Selects elements by their tag name. 🔹 getElementsByName() – Selects elements using their name attribute. 🔹 querySelector() – Selects the first element that matches a CSS selector. 🔹 querySelectorAll() – Selects all elements that match a CSS selector. Example 👇 document.getElementById("demo").innerHTML = "Hello DOM!"; document.querySelector(".btn").style.color = "blue"; ✨ With DOM manipulation, we can create interactive, dynamic, and user-friendly web pages that respond instantly to user actions! #JavaScript #WebDevelopment #Frontend #Learning #DOM #Coding

🚀Understanding the DOM in JavaScript In this session, we dived into one of the most essential concepts in web development — the Document Object Model (DOM). 🌳 What is the DOM? The DOM represents an HTML document as a tree structure, enabling JavaScript to access, modify, and dynamically interact with webpage content, structure, and styling. ✅ Topics We Covered 🔍 Accessing DOM Elements getElementById() – Select elements using a unique ID getElementsByClassName() – Retrieve elements by class getElementsByTagName() – Select elements using tag names querySelector() – Fetch the first match to a CSS selector querySelectorAll() – Fetch all matches to a CSS selector 🛠️ Manipulating DOM Elements setAttribute() – Add or update attributes createElement() – Dynamically create HTML elements innerHTML – Insert or update HTML content 🎛️ Accessing User Input Using .value, we can retrieve user-entered data from: Text fields Dropdowns Text areas ⚡ DOM Events We Explored onclick onchange onsubmit onkeypress / onkeydown / onkeyup onmouseover / onmouseout onload ✅ What We Practiced Accessing HTML elements using document.getElementById() Reading values from input fields, dropdowns, and text areas Displaying output dynamically using innerHTML Handling user interactions through onclick events 🖥️ Output on Browser When the user enters their name, email, and selects a city, clicking the Submit button displays all the information directly on the webpage — no reloads, no console logs, just smooth DOM manipulation. 🎯 Key Takeaways The DOM enables real-time interaction between HTML and JavaScript innerHTML helps display dynamic content instantly Event handling makes web pages interactive and user-friendly A big thank you to Ravi Siva Ram Teja Nagulavancha Sir Saketh Kallepu Sir Uppugundla Sairam Sir Codegnan #WebDevelopment #JavaScript #DOM #Frontend #HTML #CSS #Programming #LearningJourney #Developers #TechEducation #Codegnan

💣 Built a Bomb Countdown Scheduler using HTML, CSS & JavaScript! I developed a mini application where a bomb countdown starts from 10 seconds and triggers an explosion visual once the timer reaches zero. Every second, the UI updates dynamically creating a realistic countdown experience. 📌 What I improved in this project: • Implementing time-based UI updates using JavaScript • Handling real-time DOM manipulation and state changes • Managing logic flow based on countdown conditions • Controlling timed events visually and functionally in the frontend ⏱️ setInterval() was used to continuously run a function every 1 second to decrement the time and update the display. 🛑 clearInterval() stopped further execution once the final condition was reached to prevent unnecessary memory usage. 💻 Tech Used: HTML | CSS | JavaScript 🔗Demo Link : https://lnkd.in/gUwb-6Hs #HTML #CSS #JavaScript #FrontendDevelopment #WebProjects #LearningByBuilding #MiniProject #JSLearning #FrontendJourney #CodeEveryDay Manoj Kumar Reddy Parlapalli

HTML builds the house, CSS paints it, but JavaScript throws the party inside! 🥳 You can stare at static HTML and CSS all day, and it might look great. You'll have buttons, text, and structure. But it's just a lifeless webpage. Then, JavaScript walks in. Take this simple calculator project I built. HTML: Set up the "8", the "2", the four operation buttons, and a place for the answer. CSS: Made it all look clean and centered. JavaScript: This is where the magic happens. 🧠 With a few lines of JS, those buttons suddenly have a purpose. They "listen" for a click, grab the numbers, perform the math, and instantly update the page with the correct answer. That's the power of JavaScript and DOM manipulation, It takes a static document and turns it into a living, interactive application. It's the engine that brings your code to life! What was the first project that made you truly appreciate the power of JavaScript? #JavaScript #WebDevelopment #FrontEndDeveloper #HTML #CSS #CodingJourney #Developer #Tech #LearnToCode

#Days29 🌟 #Lecture14 - Mastering DOM Manipulation in JavaScript Today, I explored one of the most essential parts of web development—DOM manipulation. It’s the foundation of creating dynamic and interactive web pages. Here’s what I learned. 👇 🔹 1️⃣ Editing Content textContent → Safest way to update plain text ✅ innerHTML: For inserting HTML, but handle with care (XSS risk ⚠️) 🔹 2️⃣ Editing Attributes, Classes & Styles Change attributes directly: img.src, div.id, input.value Manage classes efficiently: element.classList.add('active'), remove(), toggle() Apply inline styles dynamically: element.style.backgroundColor = 'blue' 🔹 3️⃣ Editing Structure (Creating & Adding Elements) Create new elements: document.createElement() Add elements: append(), prepend(), before(), after() Remove elements easily: element.remove() 🔹 4️⃣ Optimize Performance with DocumentFragment When adding multiple elements (like 1000 list items), Use a DocumentFragment to reduce reflows and make DOM updates faster. const fragment = document.createDocumentFragment(); for (let i = 0; i < 1000; i++) { const li = document.createElement('li'); li.textContent = `Item ${i}`; fragment.appendChild(li); } list.appendChild(fragment); // Single efficient update 💡 Key Takeaway: Efficient DOM manipulation = faster, smoother, and more responsive user interfaces. A heartfelt thank you to Rohit Negi Bhaiya for your constant guidance, support, and clear explanations. #JavaScript #WebDevelopment #Frontend #DOM #LearningJourney #Programming #Tech

: 🧠 Explanation (for your video) In this video, I created a simple Light and Dark Mode Toggle using HTML, CSS, and JavaScript. When the button is clicked, the background color and text color switch between light and dark themes dynamically. HTML defines the structure — it includes a heading and a button. CSS styles the page, centers the content, and adds color and shape to the button. JavaScript handles the functionality — when the user clicks the button, it changes the background, text color, and button label based on the mode. This project helps beginners understand how to connect HTML, CSS, and JS together to make an interactive web page. 💬 Comment (for posting or describing the project) 🚀 Light & Dark Mode Toggle using JavaScript A simple yet cool project that switches between light and dark themes with just one click! 🌗 This small project helped me practice DOM manipulation and event handling in JavaScript. #JavaScript #FrontendDevelopment #WebProjects #CodingJourney #LightDarkMode 10000 Coders Manoj Kumar Reddy Parlapalli Usha Sri
