alternative to Element.getBoundingClientRect() by https://github.com/kirupa

getPosition.js

function getPosition(elm) {
  var xPos = 0, yPos = 0;
  
  while(elm) {
    xPos += (elm.offsetLeft - elm.scrollLeft + elm.clientLeft);
    yPos += (elm.offsetTop - elm.scrollTop + elm.clientTop);
    elm = elm.offsetParent;
  }
  
  return { x: xPos, y: yPos };
}

It was helpful for me. But how to pass parameter? I have added function call with parameter.
getPosition(window.frameElement);
Thanks.

very useful for sticky feature.

var pos_t = getPosition(i_sticky_i);
alert(pos_t.x);

ok.

It's alternative, but what's the purpose? This will cause reflow several times instead of one using getBoundingClientRect

this is even worse than getBoundingClientRect.

I was trying to use this 'getBoundingClientRect'. but every time i get an error of null. I used this and it works! Wow... Great work 💯
