jquery - Get bottom and right position of an element

Question

I'm trying to get the position of an element within the window like so:

var link = $(element);

var offset = link.offset();
var top = offset.top;
var left = offset.left;
var bottom = $(window).height() - link.height();
bottom = offset.top - bottom;
var right = $(window).width() - link.width();
right = offset.left - right;

However the bottom and right have - in front of them... Why is this? as the numbers are correct just they should NOT be minus.

Answer 1

Instead of

var bottom = $(window).height() - link.height();
bottom = offset.top - bottom;

Why aren't you doing

var bottom = $(window).height() - top - link.height();

Edit: Your mistake is that you're doing

bottom = offset.top - bottom;

instead of

bottom = bottom - offset.top; // or bottom -= offset.top;
