Subtract from an integer using jquery

Question

I want to scroll to a div each time user presses j key. Here is the code for it.

$(function() {
    function scroll(direction) {

        var s         


        

Answer 1

Try putting some space between your minus symbol so it does not get mistaken for a dash.

$('html, body').animate({"scrollTop": $(scroll).offset().top - 50});

or save your mathematics in a variable first

var scrollMinusFifty = $(scroll).offset().top - 50;
$('html, body').animate({"scrollTop":scrollMinusFifty});
