Pass custom parameters through Form submit

Hello Everyone,

I’d like pass custom datas stored in javascript variables, through Form submit. I tried:

  • Hidden fields with custom value in the form. With a script I changed the predefined value of the field, but the datas has overwritten when I submitted the form.
  • Hidden fields with URL parameters. I wrote the datas to URL parameters, but they vanished when I submitted the form, and the datas haven’t passed to Airtable. It is only worked when I refreshed the page, then the parameters have passed, but I don’t want reload the page.

I’d appriciate your help in this topic. Thanks in advance.
