Pop-Up layer

In the pop-up layer, I have finished all the work on the pop-up layer. the pop-up layer may have multiple identical table information, now I want to put the information entered by the pop-up layer in its parent form for synchronous submission.
I don't know how to save the information to this large form. Help me!

When entering the table information, the user puts the information entered in the hidden input defined in the form.
For example:

Is it implemented using js? but if there are multiple table information at a time, the implementation is still quite confusing. new users are coming soon. could you help me?

If JavaScript is used, the information is inserted into the input of the hidden form of form every time a table User points are displayed for confirmation.
