文档 Object Model ( DOM ) 中的“型号”是什么意思？

Question

I'm learning web development and came across the concept of DOM. There are many resources which have explained what is DOM and what it does.

But I couldn't find any resource explaining meaning of "Model" in "Document Object Model ( DOM )". What does it mean?

Answer 1

I've found couple of good answers as below

1. In programming the term "model" often refers to a data structure. For the DOM, it is referring to the structure of the document. The document is an object with properties and the structure of it all is predetermined by the model.

2. In a general sense, “model” can just be the shape of data. Like in a language like TypeScript, I might define a person as:

    interface Person { name: string age: number address: { house: number street: string city: string state: string zip: string } phones: string[] }

That is just the model for how I represent a “person” in my data.

In a more general sense, the DOM is just a model, an abstract representation of what is on the screen. It (the data and therefore the model) has a certain shape and hierarchy.

Answer 2

As the name suggests, it's a model for things In this case, model of the document A model is as the plan of city or house, it describes how it look

The model describe and give you the representation of your document
