Introduction to HTML DOM and new features

Introduction

• In the core DOM, the properties and methods provided can already operate web pages. Why do we need HTMLDOM?

• If in the core DOM, the node level in the web page is very deep, it will be very troublesome to access this node.

• Then, HTMLDOM provides a method to directly find nodes by id, instead of starting from the HTML root node.

##New features of HTMLDOM

• Each HTML tag corresponds to an element object. For example: corresponds to an image object

• . The attributes of each HTML tag correspond to the attributes of the corresponding element object in a one-to-one correspondence.
