Javascript DOM-Beginner 2

Today I have read some comments about Javascript DOM. Javascript DOM is a very good thing and I feel very powerful. Although I have not really seen its powerful power, but you can only look at one or two items from its name. Dom is divided into three letters: "D", "O", and "M", representing three keywords: "document", "object", and "model ". Documents, objects, and models represent almost the whole process of software development. However, although they do not represent software development, in the field of web development, we can also see the huge capabilities of these three keywords.

I like five common Dom Methods: getelementbyid, getelementbytagname, getelementbyclassname, getattribute, and setattribute. These five basic methods are the cornerstone of writing Dom scripts. They provide powerful capabilities for developers and greatly simplify the development complexity.
