📀DOM

The Document Object Model (DOM) is a programming interface for web documents that represents the page as a tree-like structure of nodes and objects. Each node represents an element, attribute, or text string in the HTML or XML document. The DOM allows developers to access and manipulate the content and structure of web pages through programming languages like JavaScript.

🌟 Purpose of the DOM 🌟

The purpose of the DOM is to provide a language-neutral programming interface for text-based documents. This makes it possible for developers to access and manipulate the content and structure of web pages through programming languages like JavaScript. The DOM is a crucial technology for modern web development, allowing web pages and applications to be dynamic and interactive.

🌟 Usage of the DOM 🌟

The DOM represents a web page as a tree-like structure of nodes and objects. Each node represents an element, attribute, or text string in the HTML or XML document. Nodes can have parent-child relationships, sibling relationships, and other types of relationships that reflect the structure of the document.

🌟 HTML DOM Tree of Objects 🌟

When a web page is loaded, the browser creates a Document Object Model of the page. The HTML DOM model is constructed as a tree of Objects. With the object model, JavaScript gets all the power it needs to create dynamic HTML. JavaScript can change all the HTML elements in the page, react to HTML DOM events, and add and delete HTML elements.

🌟 HTML DOM Methods 🌟

The HTML DOM provides a set of methods and properties for accessing and manipulating HTML elements. Some of the commonly used methods are:

• getElementById()returns the element with the specified ID.

• getElementsByTagName()returns a collection of elements with the specified tag name.

• getElementsByClassName()returns a collection of elements with the specified class name.

• createElement()creates an HTML element.

• appendChild()adds a new child node to an element.

• removeChild()removes a child node from an element.

🌟 Conclusion 🌟

The Document Object Model (DOM) is a crucial technology for modern web development, allowing web pages and applications to be dynamic and interactive. It represents the page as a tree-like structure of nodes and objects, where each node represents an element, attribute, or text string in the HTML or XML document. The HTML DOM provides a set of methods and properties for accessing and manipulating HTML elements, making it possible for developers to create dynamic HTML pages using JavaScript.
