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

$(scroll).offset().top-50 is prefectly valid, as .top will return an integer value. Therefore the issue is not with this portion of your code.

I suspect the issue is to do with the scroll variable you have within the scroll function. I always keep away from naming my variables the same as my function names when within the same scope.
