Conditionally Replace Logo with Alt Logo

Hi there I’m trying to replace the default black logo with a white alternative with js. Below is the snippet that used to work until recent wordpress updates… Please help!

This link should show a white logo not black like the menu color (white)

jQuery(document).ready(function($){
       //replace black logo with white logo
	  // full urls in between the ticks
      var
      logodefault = 'https://sscreativestudio.com/wp-content/uploads/2015/11/logo.png',
      logowhite = 'https://sscreativestudio.com/wp-content/uploads/2015/11/logo-white.png';

      if ($('body').hasClass('label-white-header')) {
         $('img[src="' + logodefault + '"]').attr('src', logowhite);
         }
        }
      else {
         //default logo
         $('img[src="' + logowhite + '"]').attr('src', logodefault);
      }
       //end if label white header
