Remove/avoid adding target link to URL

Remove/avoid adding target link to URL

This one may be simple for the jQuery/JavaScript gurus here, but I just
can't find a solution for it around the web.
Case
I have a link at the bottom of a page that says Back to Top, the link is
simply a target link like this:
<a href="#top" class="standard">Back to Top</a>
So when you click it, it jumps to the top of page. Simple.
Problem
When the target link is clicked, the id #top is added to the URL of the
page, ie:
http://website.com/about-us/#top
Question
Is there a way to remove or avoid getting that id #top added to the URL of
the page but retain the functionality of the page jumping to the top?
Any help with this is greatly appreciated.
