JavaScript HTML DOM
🎯 한 줄 통찰 (One-line insight)
The HTML DOM is an object model that represents an HTML page as a tree of nodes, giving JavaScript a standardized way to access and change every element on the page. [S1]
🧠 핵심 개념 (Core concepts)
- The HTML DOM is an Object Model for HTML Documents — it represents an HTML page as a tree of nodes. [S1]
- The browser builds the tree on load — when a webpage loads, the browser creates a tree-like representation of the document made of nodes: Document, Element nodes (such as
<html>,<body>,<a>), Attribute nodes, and Text nodes. [S1] - Three roles in one access expression —
id="demo"is an HTML property,getElementById()is a DOM method, andinnerHTMLis a DOM property. [S1] - The DOM is a W3C Standard — defined by the World Wide Web Consortium in three parts: Core DOM, XML DOM, and HTML DOM. [S1]
🧩 추출된 패턴 (Extracted patterns)
- Access then modify — get a node reference with a DOM method, then read or write a DOM property on it. [S1]
- Tree traversal mindset — because the page is a tree of nodes, navigation and manipulation are expressed in terms of elements, attributes, and text nodes. [S1]
📖 세부 내용 (Details)
The HTML DOM [S1] The HTML DOM (HTML Document Object Model) is an Object Model for HTML Documents. It represents an HTML page as a tree of nodes. [S1]
The DOM Tree [S1]
When a webpage loads, the browser creates a tree-like representation of the document. This tree is made of nodes for the different parts of the document: the Document node, Element nodes (for example <html>, <body>, <a>), Attribute nodes, and Text nodes. [S1]
Accessing HTML Elements [S1] HTML elements are accessed through the document. The following example accesses a paragraph element by its id and changes its content: [S1]
// Access a paragraph Element
const myPara = document.getElementById("demo");
// Change the content of the Element
myPara.innerHTML = "Hello World!";
In this example, id="demo" is an HTML property, getElementById() is a DOM method, and innerHTML is a DOM property. [S1]
What You Will Learn [S1] The tutorial covers how to: change the content of HTML elements, change the style (CSS) of HTML elements, add and delete HTML elements, and react to HTML events. [S1]
The World Wide Web Consortium [S1] The DOM is a W3C Standard (World Wide Web Consortium). The W3C DOM standard is separated into three parts: Core DOM, XML DOM, and HTML DOM. [S1]
🛠️ 적용 사례 (Applied in summary)
The page's own snippet — selecting #demo with getElementById() and assigning to innerHTML — is the canonical applied example. No external project/commit applications found in the source.
💻 코드 패턴 (Code patterns)
Access an element by id and change its content (language: JavaScript):
const myPara = document.getElementById("demo");
myPara.innerHTML = "Hello World!";
