You know, you never trust the data submitted by the user.

The front-end prohibition is only for the user experience. If you really need to filter user transmission, you only need to perform operations on the back-end. In this case, you don't need to worry about this when the backend performs data operations.InputAs long as the value in the database does not change, you can freely ~

Directly p a border that looks like input

Name is not added to input.
Not processed by the backend.

You can hide the real input and put it on false. Of course, the problem still exists. The key is background verification instead of relying on the browser.

What can I do when the backend selects data?

This is easy to do. It is also set the input attribute.
