I would like to have a confirmation on some point.
My goal is to always get the same string (which is the URI in my case) while reading the href property from a link
I know it's an old question, but this being actually the first entry that popped up, I believe it's good to add an extra solution. Ever since jQuery introduced the "prop" function, getting the full URL is as simple as:
$(my_a_dom_node).prop('href');
I hope that still helps somebody.
