How to get built-in services to obtain local information in Angular

We used angular to set a timer before. Today we will do some exercises based on the timer.

Use the built-in service to obtain the following information:

1. Get the screen height

2. Get the screen width

3.Get the pagetitle

4.GetURLProtocol

5.GetURLHost

6. Get the port number

7.Get the hash part of URL

8.Get the access address, that is, URLAddress

##Other requirements:

1. The height and width are displayed 2 seconds after opening the page

2.title, protocol, host will be displayed 3 seconds after opening the page

3. Port number, url address will be displayed 5 seconds after opening the page After that, a prompt box will pop up asking whether to display it. If you click yes, it will be displayed. Otherwise, it will not be displayed.
