javascript - To what extent can the front-end use js to access http information?

1. Where is the connection point between the front end (excluding the nodejs part) and http? Xhr and post/get are known. What about other places?

2. Can the front end make client judgment and page jump by reading the http loading information?

3. Can the front end only obtain http header information? Can the page loading progress (page loading) be judged through http information?

4. What else can be done using js and http, and what are the usage scenarios?

From the moment you open the browser and visit the page, you can’t live without http (or maybe https). What else do you want? ^^

Can the front end make client judgment and page jump by reading the http loading information?

I don’t understand what you are talking about. "The front end reads the information loaded by http" - what information? ; "Client judgment and page jump" - Of course the client can jump, just use location. What are you trying to judge?

Can the front end only obtain http header information? Can the page loading progress (page loading) be judged through http information?

"Can the front end only get http header information?" How is that possible? Don't make trouble. Can't you still get ajax if you send response^^; "Can you judge the page loading progress through http information ( Page Loading)", this may be a bit difficult.

What else can be done using js and http, and what are the usage scenarios?

I thought about it for a while and realized that when you said http, did you actually mean ajax? I’m a bit confused
