Check if current URL contains hash

Question

Using Javascript how do you check if current URL contains an hash?

In test page I want to add a Javascript code to print:

<p>yes, there is a hash here</p>

if hash is present (current page http://www.example.com/test/#abc) or:

<p>no, there is no hash here</p> 

if hash is not present (current page http://www.example.com/test/).

Answer 1

It's straightforward

if(window.location.hash) {
   //# in URL
}
