How to get the result of a function without reloading the page?

Question

Python

Good day!

I can not solve the following problem in any way: "I have a page on which the user enters values ​​into inputs. After that, they are multiplied with the values ​​​​taken from the Excel spreadsheet, but the result is displayed only after clicking the "Confirm" button. I need, so that it does it on the same page as soon as the values ​​in the rows change"..

Every helpful answer/link would be greatly appreciated.

but instead of the click event, you need to use the blur event or input
, and I advise here too. look
