How can you check for a #hash in a URL using JavaScript?

Question

I have some jQuery/JavaScript code that I want to run only when there is a hash (#) anchor link in a URL. How can you check for this character using JavaScript?

Answer 1

  if(window.location.hash) {
      var hash = window.location.hash.substring(1); //Puts hash in variable, and removes the # character
      alert (hash);
      // hash found
  } else {
      // No hash found
  }
