How to remove scrolling to a block without changing the url?

Question

JavaScript

Implemented scrolling, when you click on one block, it will scroll to another.

var el = $(this).attr('href');
$('html, body').animate({
    scrollTop: $(el).offset().top - 50
}, 1500);
return false;

But when you click on the block, the url changes, how can I scroll without changing the url ?
