Dokumentobjectmodeller

Dokumentobjectmodeller, often abbreviated as DOM, is a programming interface that allows programs and scripts to dynamically access and update the content, structure, and style of a document. The DOM represents the document as a tree structure where each node is an object representing a part of the document, such as an element, attribute, or text. This hierarchical structure allows for easy navigation and manipulation of the document's content.

The DOM is a crucial component of web development, particularly in the context of HTML and XML documents. It provides a standardized way for developers to interact with the web page's content, enabling dynamic updates without requiring a page reload. This is particularly useful for creating interactive web applications, where the content can change based on user actions or other events.

The DOM is supported by all major web browsers and is a key part of the Document Object Model (DOM) standard, which is maintained by the World Wide Web Consortium (W3C). The DOM Level 1 specification, published in 1998, provided the basic structure and methods for interacting with documents. Subsequent levels, including DOM Level 2 and DOM Level 3, have expanded the functionality to include more advanced features such as event handling, styling, and traversal.

In summary, Dokumentobjectmodeller is a powerful and versatile interface that enables dynamic interaction with web documents, making it an essential tool for modern web development. Its ability to represent documents as a tree of objects allows for efficient navigation and manipulation, contributing to the creation of interactive and responsive web applications.
