I don't see why window.onload should not fire for you. Are there other 
scripts in the whole code that also try to set window.onload?
Is that page online somewhere to check?

In general these days, unless you need to support IE 8, it should 
suffice to use the DOMContentLoaded event instead e.g. instead of
   window.onload = getCart;
you can set
   document.addEventListener('DOMContentLoaded', function(evt) { 
getCart(); } false);
as window.onload waits for all resources like images to load while 
DOMContentLoaded should fire once the document's source has been parsed 
and the DOM has been built, without waiting for images or other 
resources to load completely.
