Question

JavaScript

Good day
There is a page with the following piece of script:

$J(window).on('scroll', function() {
  ...
});
$J(window).on('mousemove', function() {
  ...
});

Actually declaring events via JQuery
I have a browser extension that will include my scripts on the page
The question is how to trigger events?

$(window).trigger('scroll');
