Reply To: JS code after successful submission of a form

Thanks a lot for the answer, but the problem just occurred when caching was enabled. The Hyper X plugin is used, and the problem is that when sending invisible fields, they are cached (ip address, time of sending, user agent, and others). Invisible fields get into the cache and remain there, however, in the CMS, the data in the additional information block is filled in correctly. In more detail in the screenshots, tell me how to make invisible fields not fall into the cache?
