Clearing URL hash

Question

Visit stackoverflow.com/#_=_ and window.location.hash evaluates to #_=_. Fine.

Now execute window.location.hash = \'\'

Answer 1

Answering to your first question:

According to the window.location doc in Mozilla.org: "the part of the URL that follows the # symbol, if there is one, including the # symbol. Empty string if the url does not contain # or has nothing after the #."

Curiously, that document was just updated on 4/8/2013. Not sure if that was added after you checked the documentation.

By the way (and in reference to the answers), the window.location.hash and pushState are different concepts although close related.
