In principle, it is used SESSION or COOKIE implemented. But if you are not a dynamic program (based on other dynamic programming languages like PHP), just an HTML file, you can rewrite the URL and add the anchor information:

去B页面

on page B, you need to use JS to get this value, such as:

var username = window.location.hash;

Of course, there are other, such as 隐藏域 . In short, the simplest is SESSION or COOKIE .

Session | | Cookies

Session or Cookie

If you do not have a service side and do not consider other security issues, you can place it in a URL.

Server-side do: Session

Client: URL contains parameters, cookies

If only for the front-end page display, can be stored in the following several common places:
1. URL
2. Cookies
3, Localstorage
4, Sessionstorage

Session or Cookie.
