Determining the position of an element on the screen through calculations

Currently working on a mobile app using backbone and encountering an issue with detecting the position of an element in a list. I attempted to use the scrollTop property, but it consistently returns zero. Is there a specific technique for determining the position of an element relative to the screen? Here is what I have tried:

   var p = $( "li:first" );
   var position = p.offset();
   console.warn(position.top);

Interestingly, this code snippet returns different values when tested on a computer versus a mobile phone.

Answer №1

Do you intend to accomplish this task in this manner?

let yPositionRelativeToScreen = p.offset().top - window.scrollY;
