Document Object Model (DOM)
The Document Object Model (DOM) is a programming interface for HTML and XML documents. It is a tree-like structure that represents the structure of a document and allows you to manipulate the contents and attributes of a document.
The DOM provides a way to access and manipulate elements in an HTML or XML document as a tree-like structure, where each element is a node in the tree. This allows you to programmatically access and manipulate elements in a document, including adding, removing, and modifying elements and their attributes.
Here is an example of using the DOM to access and modify an HTML element:
<p id="greeting">Hello World!</p>
<script>
let greeting = document.getElementById("greeting");
greeting.innerHTML = "Hello DOM!";
</script>
In the example, the DOM is used to access the <p> element with the id attribute "greeting". The innerHTML property is used to change the content of the element to "Hello DOM!".
The DOM is a standard part of most web browsers and is widely used by JavaScript programmers to interact with and manipulate web pages. Understanding the DOM is an essential part of web development and JavaScript programming.
