1, top and left relative to the document

Get the current coordinates of the first element, or set the coordinates of every element, in the set of matched elements, relative to the document.

var top = $('#elementID').offset().top;
var left = $('#elementID').offset().left;

var viewportOffset = el.getBoundingClientRect();
// these are relative to the viewport
var top = viewportOffset.top;
var left = viewportOffset.left;

var topToParent = $('#elementID').position().top;
var leftToParent = $('#elementID').position().left;

The HTMLElement.offsetTop read-only property returns the distance of the current element relative to the top of the offsetParent node.

var topToParent = element.offsetTop;
var leftToParent = element.offsetLeft;
