Get bottom and right position of an element

Solution 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;

Solution 2:

var link = $(element);
var offset = link.offset();

var top = offset.top;
var left = offset.left;

var bottom = top + link.outerHeight();
var right = left + link.outerWidth();

Solution 3:

// Returns bottom offset value + or - from viewport top
function offsetBottom(el, i) { i = i || 0; return $(el)[i].getBoundingClientRect().bottom }

// Returns right offset value
function offsetRight(el, i) { i = i || 0; return $(el)[i].getBoundingClientRect().right }

var bottom = offsetBottom('#logo');
var right = offsetRight('#logo');

This will find the distance from the top and left of your viewport to your element's exact edge and nothing beyond that. So say your logo was 350px and it had a left margin of 50px, variable 'right' will hold a value of 400 because that's the actual distance in pixels it took to get to the edge of your element, no matter if you have more padding or margin to the right of it.

If your box-sizing CSS property is set to border-box it will continue to work just as if it were set as the default content-box.

Solution 4:

You can use the .position() for this

var link = $(element);
var position = link.position(); //cache the position
var right = $(window).width() - position.left - link.width();
var bottom = $(window).height() - position.top - link.height();
