title: How to make a javascript alert NOT say the name of the page?
body: <p>My webapp alert looks like this:</p>
  
  <hr>
  
  <p>InputCoordinates.html</p>
  
  <p>Latitude must be filled out.</p>
  
  <hr>
  
  <p>I would say this looks unprofessional and rough around the edges. Is there a way to stop the alert from displaying the pagename?</p>
