Why does the site reset the value of input fields when they are entered via Jquery?

Question

JavaScript

This code is injected into the DOM of the page, it has a simple authorization form and a submit button.
The fields are filled, but the button remains inactive, and if you poke somewhere, the fields are reset.
What is the best way to implement this? Thanks in advance.

Answer 1

1) Wait, isn't that how it's supposed to work? 2) If it doesn't help, try triggering the onchange event for input fields before clicking.
