What is the DOM?
The Document Object Model (DOM) is a programming interface for HTML and XML documents. It represents the structure of a document as a tree of objects.
Accessing Elements
You can access DOM elements using methods like getElementById, querySelector, and getElementsByClassName.
Example: Changing Text
document.getElementById("demo").innerHTML = "Hello, DOM!";
Event Handling
JavaScript allows you to handle user interactions like clicks, mouse movements, and keyboard input using event listeners.
Example: Button Click
document.getElementById("myButton").addEventListener("click", function() {
alert("Button clicked!");
});
Dynamic Content
You can dynamically add, remove, or modify elements in the DOM using JavaScript. This is useful for creating interactive web pages.
Example: Adding an Element
const newElement = document.createElement("p");
newElement.textContent = "This is a new paragraph.";
document.body.appendChild(newElement);
