The Doucment Object Model (DOM) is an application interface that represents documents (such as HTML documents and XML documents) and various elements used to access and operate documents. In the DOM, the HTML document hierarchy is represented as a tree structure. The node of the tree indicates various content in the document. BKJIA recommended reading: The nature and operation methods of JavaScript DOM The DOM tree structure is the tree of various typ
