In informatica il Document Object Model (spesso abbreviato come DOM), letteralmente modello a oggetti del documento, è una forma di rappresentazione dei documenti strutturati come modello orientato agli oggetti. The HTML DOM is an Object Model for HTML.
DOM non pone limitazioni alla struttura dei dati di un documento. The DOM defines what attributes are associated with each object, and how the objects and attributes can be manipulated. Be...

Each branch of the tree ends in a node, and each node contains objects. Any HTML or XML element (with the possibility of a few exceptions) will be individually addressable by programming. The W3C home page announces new developments. The DOM defines what attributes are associated with each object, and how the objects and attributes can be manipulated.

DOM è utilizzato principalmente per recuperare informazioni da documenti con una strutturazione non standard, cioè dove gli elementi devono essere trovati in modo casuale. Both companies have submitted their DOMs to the World Wide Web Consortium (W3C) for standardization, which now has the daunting task of specifying a standard DOM without alienating either of the browser giants. It's not unusual for enterprises to scale their applications to meet demand, but they need to be aware of the associated cloud ...

The DOM defines a standard for accessing documents: "The W3C Document Object Model (DOM) is a platform and language-neutral interface that allows programs and scripts to dynamically access and update the content, structure, and style of a document." The Document Object Model (DOM) is a cross-platform and language-independent interface that treats an XML or HTML document as a tree structure where in each node is an object representing a part of the document. Dynamic HTML (DHTML) relies on the DOM to dynamically change the appearance of Web pages after they have been downloaded to a user's browser.

In informatica il Document Object Model (spesso abbreviato come DOM), letteralmente modello a oggetti del documento, è una forma di rappresentazione dei documenti strutturati come modello orientato agli oggetti. È inoltre la base per una vasta gamma di interfacce di programmazione delle applicazioni, alcune di esse standardizzate dal W3C. In the DOM specification, the term "document" is used in the broad sense - increasingly, XML is being used as a way of representing many different kinds of information that may be stored in diverse systems, and much of this would traditionally be seen as data rather than as documents.
Short for Document Object Model, the specification for how objects in a Web page (text, images, headers, links, etc.) are represented. Questa pagina è stata modificata per l'ultima volta il 15 apr 2020 alle 16:56. It was inspired in part by the advent of the new HTML capabilities generally called dynamic HTML and as a way to encourage consistent browser behavior with Web pages and their elements. Specifiche Traversal and Range DOM Livello 2, Specifiche caricamento e salvataggio DOM Livello 3, Specifiche di visualizzazione e formattazione DOM Livello 3. Document Object Model (DOM), a programming interface specification being developed by the World Wide Web Consortium (W3C), lets a programmer create and modify HTML pages and XML documents as full-fledged program objects. La specifica attuale di DOM è al Livello 2, tuttavia alcune delle specifiche del Livello 3 ora sono già raccomandazioni del W3C. As program objects, such documents will be able to have their contents and data "hidden" within the object, helping to ensure control over who can manipulate the document.

Nativamente supportato dai browser per modificare gli elementi di un documento HTML, DOM è un modo per accedere e aggiornare dinamicamente il contenuto, la struttura e lo stile dei documenti. Currently, HTML (Hypertext Markup Language) and XML (Extensible Markup Language) are ways to express a document in terms of a data structure. Questa implementazione richiede che l'intero contenuto di un documento venga analizzato e salvato in memoria.
È da notare che in questo esempio anche i cosiddetti caratteri blank (spazi, tabulazioni, ecc.)
It defines the logical structure of documents and the way a document is accessed and manipulated.
