How does js get the access page record (can you tell me what you know)

The boss assigned a task this time, but I can't do it in several places. Please do me a favor. The main task is to use js to get: 1. The source of the website is intercepted 2. Intercept 3. 3 by IP. The Internet address is intercepted 4. The operating system intercepts 5. Resolution intercept 6. Access to the page count record, but I can only get 1. Source of the website 4. Operating system 5. Resolution of these several, of which the Internet IP, the address I intercepted, but some people say that my method of interception is not good, so can any of you tell me how to intercept these? thank you, this is the code I wrote, can you tell me what the text effect is?
