Today, I will talk to you about the use of the three nodes in the DOM model, which may not be well understood by many people. in order to make you understand better, the editor has summarized the following content for you. I hope you can get something according to this article.

Nodes in DOM Model

There are three kinds of nodes in the DOM model: element node, attribute node and text node.

Element node

It can be said that the whole DOM model is made up of element nodes. Element nodes can contain other elements, for example, they can be included in, and the only thing that is not included is the root element HTML.

Attribute node

As elements on a page, there are more or less attributes. For example, almost all elements have title attributes. Developers can use these attributes to describe the objects contained in the element more accurately. For example:

I am in charge of my data network.

In the above code, href= "http://www.sutao123.cn"" and "title=" are two attribute nodes respectively. Because attributes are placed in tags, attribute nodes are always included in element nodes.

Text node

In HTML, it is not enough to build frames. The ultimate goal of a page is to present content to users. For example, in the above example, "I am in charge of my data network" this is a text node that we want to show to the user.
