JavaScript gets a method to specify the location of an element

This example shows how JavaScript gets the location of a specified element. Share with you for your reference. The details are as follows:

function showpane() {

  var self = document.getElementById("eID");

  var left = self.getBoundingClientRect().left + document.documentElement.scrollLeft;

  var top = self.getBoundingClientRect().top + document.documentElement.scrollTop + self.offsetHeight;

}

I hope this article has been helpful to your javascript programming.
