The Document Object Model (DOM) is a tree-like structure that represents the structure of an HTML document. In JavaScript, the DOM can be manipulated to change the appearance and behavior of a web page.
There are several methods in JavaScript for accessing and manipulating elements in the DOM, including:
document.getElementById(id)
: returns the element with the specified iddocument.querySelector(selector)
: returns the first element that matches the specified selectorelement.innerHTML
: gets or sets the HTML content of an elementelement.style
: gets or sets the style of an elementelement.classList
: gets or sets the classes of an element
In addition to these methods, there are several DOM events that can be used to respond to user interactions with elements, such as clicks, hover, and form submissions. These events can be handled using event listeners.
element.addEventListener("event", function() {
// code to be executed when event occurs
});
DOM manipulation is an important aspect of web development and is used to create dynamic, interactive websites. Understanding how to manipulate the DOM is essential for creating effective and engaging user experiences.
