Javascript: Automaticly Count and Display the Number of Words on a Web Page

I was wondering if anyone can assist me with this problem: I am trying to type in code that Automaticly Counts and Displays the Number of Words on a Web Page using JavaScript.

I have searched stack overflow and the internet in general, and there does not seem to be any examples on this that can help. :(

Thank you, any help will be appreciated.
