Why do we need DOM Manipulation?
DOM manipulation is important because it allows us to dynamically change the content of a webpage without having to reload the entire page. This enhances the user experience by making the website more interactive and responsive.
- Selecting Elements: The first step in DOM manipulation is selecting the element(s) that we want to manipulate. We can use various methods such as getElementById, getElementsByClassName, getElementsByTagName, and querySelector to select elements.
// Select the element var element = document.getElementById("myElement"); // Change the text content element.textContent = "New text content";
// Create a new element var newElement = document.createElement("div"); // Set the element attributes newElement.setAttribute("id", "newElement"); newElement.setAttribute("class", "myClass"); // Set the element content newElement.textContent = "New element content"; // Add the element to the DOM document.body.appendChild(newElement);
