DOM Full Form Is Document Object Model. And The Document Object Model (DOM) is a programming API for HTML and XML documents. It defines the logical structure of the documents and the way the document is accessed and manipulated. The Document Object Model (DOM) is an interface that represents web pages in a tree-like structure to facilitate access and management of elements. And When a web page is loaded, the browser creates a document object model of the page. It translates web page content into standardized objects that can be easily accessed and modified. Web pages are referred to as documents in the web world.

Accessing the DOM

You don’t need to do anything special to start using the DOM. You access APIs directly in JavaScript, called scripts, a program run by a browser.

When you create a script, whether it is inline in an element or included in a Web page, you can immediately use the API for the document or window object to manipulate the document, or from various elements of the Web page. Can start using anyone. (descendant elements of the document). Your DOM programming can be as simple as the following example, which displays a message on the console using the console.log() function.
Since it is generally not recommended to manipulate the structure of the page (written in HTML) and the DOM (written in JavaScript), the JavaScript parts will be grouped together here and separated from the HTML.

DOM and Javascript

The previous short example, like almost all examples, is JavaScript. In other words, it is written in JavaScript but uses the DOM to access the document and its elements. The DOM is not a programming language, but without it, the JavaScript language would have no model or notion of web pages, HTML documents, SVG documents, and their component parts. The document as a whole, headings, tables within a document, table headers, text within table cells, and all other elements of a document are part of that document’s document object model. All of them can be accessed and manipulated using scripting languages like DOM and JavaScript.

The DOM is not part of the JavaScript language, but a web API used to build websites. JavaScript can be used in other contexts as well. For example, Node.js runs JavaScript programs on computers but provides a different set of APIs, and the DOM API is not a core part of the Node.js runtime.

The DOM was designed to be independent of any particular programming language, allowing the structural representation of a document to be available from a single, consistent API. Even though most web developers will only access the DOM via JavaScript, implementations of the DOM can be built for any language, as this Python example demonstrates.

DOM Full Form: DOM interface

This guide is about objects and the actual things you can use to manipulate the DOM hierarchy. And there are many points where understanding how these work can be confusing. For example, an object representing an HTML form element gets its Name property from the HTMLFormElement interface, but its ClassName property from the HTMLElement interface. And In both cases, the property you want is in that form object.

But the relationship between objects and the interfaces they implement in the DOM can be confusing, and so this section attempts to say something about the actual interfaces and how they are made available in the DOM specification.

Interfaces And Objects

Many objects borrow from many different interfaces. The Table object, for example, implements a special HTMLTableElement interface, which includes methods such as creating a caption and insertRow. But since it is also an HTML element, the table implements the Element interface described in the DOM Elements Reference chapter. And finally, since an HTML element is also, as far as the DOM is concerned, a node in the tree of nodes that forms the object model for an HTML or XML page, the Table object also implements the more basic Node interface, The element from which it is obtained.

Core Interface in the DOM

This section lists some of the most commonly used interfaces in the DOM. The idea is not to describe what these APIs do here but to give you an idea of ​​the methods and properties you will often see when using the DOM. These common APIs are used in the long examples in the DOM Examples chapter at the end of this book.

The document and window objects are the objects whose interface you use most commonly in DOM programming. In simple words, the window object represents something like a browser; and the document object itself is the root of the document. The element inherits from the generic Node interface, and these two interfaces together provide a number of methods and properties that you use on different elements. These elements may also have specific interfaces for dealing with the types of data for those elements, as in the Table object example in the previous section.

DOM Full Form: What are DOM and its types?

“The W3C Document Object Model (DOM) is a platform and language-neutral interface that allows programs and scripts to dynamically access and update a document’s content, structure, and style.” The W3C DOM standard is divided into 3 distinct parts: Core DOM – The standard model for all document types.

How does the Javascript DOM work?

How does the DOM work? The Document Object Model or DOM is an interface that defines how the browser reads your XML or HTML document. JavaScript is allowed to manipulate the structure and style of your webpage. Once the browser has read the HTML document, it creates a representational tree known as the Document Object Model.

DOM Full Form: What is a DOM tree?

The Document Object Model (DOM) is a cross-platform and language-independent interface that treats an XML or HTML document as a tree structure in which each node is an object representing a part of the document. So The DOM represents a document containing a logical tree.

What is DOM on the web?

The Document Object Model (DOM) is a programming API for HTML and XML documents. So It defines the logical structure of the documents and the way the document is accessed and manipulated.

How is the DOM made?

The DOM tree starts from the topmost element which is the HTML element and branches out according to the occurrence and nesting of HTML elements in the document. Whenever an HTML element is found, it creates a DOM node (Node) object from its corresponding class (constructor function).
