javascript - Full height of a html element (div) including border, padding and margin?

Question

I need the full height of a div, I'm currently using

document.getElementById('measureTool').offsetHeight

offsetHeight - Returns the height of an element, including borders and padding if any, but not margins

But one of the nested elements inside the div, has a margin-top of 20%, so I get a wrong measurement. I tried style.marginTop and scrollHeight without success.

How can I get the full height (border, padding, margin) of an element (div) in javascript?

If there isn't any other way I'm ok with jQuery.

What about something like this (no jquery)? It's similar to @gdoron's answer but a little simpler. Tested it in IE9+, Firefox, and Chrome.

function getAbsoluteHeight(el) {
  // Get the DOM Node if you pass in a string
  el = (typeof el === 'string') ? document.querySelector(el) : el; 

  var styles = window.getComputedStyle(el);
  var margin = parseFloat(styles['marginTop']) +
               parseFloat(styles['marginBottom']);

  return Math.ceil(el.offsetHeight + margin);
}

Here is a working jsfiddle.
