javascript - Can the html page use js to directly call the interface?

Question

The company is building a shopping mall website with a Java interface, but my friend only knows HTML and does not know back-end languages.
In terms of feasibility, all the pages of the mall use js cross-domain and remove the interface, without any background language. Can such a project be completed?

Answer 1

The oldest front-end and back-end separation is like this. HTML files are placed on the static server. The browser accesses the static server to get the HTML and other resource files. After parsing, it sends an ajax request to the backend interface. The backend returns the data in Fill in the browser.

The static server serves as the entrance, provides static file services, and forwards interface requests, so there is no need to cross domains.

The disadvantage of this solution is the SEO problem. If SEO is not considered, this architecture is feasible.

Answer 2

Yes, it will be no problem if the backend interface allows cross-domain access

Nowadays, many people use this method to separate the front and back ends. The front end only needs to do routing and data binding

Answer 3

Yes, use CORS cross-domain.

Answer 4

Yes, no problem

Answer 5

No problem, you can. Use http protocol

Answer 6

Use JSONP
