Chapter 3. Element Nodes
3.1 HTML*Element Object Overview
Each element in an HTML document has a unique nature, and as such,
each has a unique JavaScript
constructor that instantiates the element as a node object in a
DOM tree. For example, an <a> element is created
as a DOM node from the HTMLAnchorElement() constructor.
In the following code, I verify that an anchor element is created from
HTMLAnchorElement().
<!DOCTYPE html> <html lang="en"> <body> <a></a> <script> /* grab <a> element node from DOM and ask for the name of the constructor that constructed it */ console.log(document.querySelector('a').constructor); //logs function HTMLAnchorElement() { [native code] } </script> </body> </html>
In the preceding code example, I am trying to make the point that each element in the DOM is constructed from a unique JavaScript interface/constructor. The following list should give you a good sense of the interfaces/constructors used to create HTML elements.
