在Angular中何时以及为哪个组件创建DOM？

Question

Does each Angular component have its own DOM? Or is it only one DOM for the index.html , and only the component selector inside the index.html have their template elements in the DOM?

Answer 1

Here's the trick:

Create an angular app, create a few components, use them in the app and Run the app:

You can check the actual DOM of the entire page by inspecting the page on your browser under Elements tab.

I had already done that and the result is:

Every component you're seeing on the screen is part of the actual DOM. So basically, though not sure but I am assuming based on my checks, All components are part of the index.html DOM.

I have tested this by viewing the ELements of the angular.io site and I found that every component displayed on the screen is part of the DOM.
