The Document Object Model (DOM) is a programming interface for HTML and XML documents. It represents the structure of a web page as a tree-like structure of objects, where each object represents an element, attribute, or text node in the HTML or XML document.
The DOM provides a way for web developers to manipulate and interact with the content of a web page dynamically using scripting languages like JavaScript. It allows developers to add, remove, or modify elements and attributes in real-time, update the content of a page without reloading the entire page, and respond to user events like clicks and key presses.
The DOM is created by the browser when it parses an HTML or XML document. When a web page is loaded, the browser creates a Document Object Model (DOM) tree that represents the structure of the web page. The DOM tree is created by parsing the HTML or XML document and creating a tree of objects that correspond to the elements, attributes, and text nodes in the document.
Each element in the DOM tree is represented by a JavaScript object that contains information about the element’s tag name, attributes, child nodes, and other properties. These objects can be accessed and manipulated using scripting languages like JavaScript, allowing web developers to create dynamic and interactive web pages.
In summary, the DOM (Document Object Model) is a programming interface for HTML and XML documents that provides a way for web developers to manipulate and interact with the content of a web page dynamically using scripting languages like JavaScript. It is created by the browser when it parses an HTML or XML document and represents the structure of the web page as a tree-like structure of objects that can be accessed and manipulated using scripting languages.
