What is HTML DOM?

The question of what is HTML DOM is one of the frequently researched topics. HTML DOM can be defined as the general name given to the DOM standard used for HTML documents.

The concept of DOM can be considered as a kind of programming interface and a standard object model. The operations performed by HTML DOM in a document are as follows:

• All basic features of HTML documents and elements are defined by DOM.
• All methods and methods that allow access to HTML elements belonging to programming languages ​​and to make changes on them are used.
• Basic events are defined for the mentioned HTML elements.

What is DOM?

DOM can be defined as the application of programming interface objects to the process of keeping HTML and XML documents, which are necessary for programming languages ​​to be connected to a web page, as nodes and objects. In this way, programming languages ​​belonging to the web page can be accessed and as a result of this access, document structures, styles or contents can be changed.

For example, a web page can be considered a document. The document with HTML source code is sometimes seen as a page on the browser, but sometimes it is seen as an HTML source. In fact, the web page is the same document in two different views. This document is represented by the DOM. Thanks to the DOM, changes can be made to the document in question.

HTML DOM is known as the system that allows changes to be made to HTML documents.

In short, DOM is not a coding language. It is a standard that represents documents in an object-based manner and makes it possible to make changes to these documents.

What are the DOM Sections?

There are 3 basic types of DOM sections. These types are as follows:

• Core DOM: It is a DOM type that can be used for all documents.
• XML DOM: It is a DOM type that can be used only for documents in XML type.
• HTML DOM: It is a DOM type that can be used for all HTML documents.

Concepts Related to DOM

• Concepts related to DOM and the meanings of these concepts are briefly as follows:
• Document: In the DOM concept, a document is a page prepared with HTML code.
• Object: Each of the elements placed in the page prepared with HTML code.
• Call: In order for a command to be activated, objects must be called in a hierarchical order. The term call means activating objects to perform their functions.
• DOM Node Tree: The name given to the structure where objects and documents are connected to each other in a hierarchical relationship. Objects and documents within this structure are connected to each other as nodes.
• DOM Methods: The name given to the actions that can be performed via the DOM. For example, each of the operations to be performed on HTML elements can be considered a method.

Basic Data Types in DOM

The basic data types in DOM are briefly as follows:

• Document
• Node
• Element
• NodeList
• Attribute
• NamedNopMap

Thanks to these data types, relevant documents can be examined and changes can be made to them. Changes can be made to HTML documents via the HTML DOM.
