title: Autofill Text Field Value with Current Page URL
body: <p>All I am looking to do is autofill a <em>hidden</em> text field with the current page URL, so that when the user submits the form, I know the page they sent the form from. This will save me a ton of headaches dealing with inquiries.</p>
  
  <p>In other words, when the page loads, I'd need the text field <strong>value</strong> to be <strong>value="http://www.example.com/"</strong></p>
  
  <p>Ideally, looking to accomplish this with just Javascript/HTML.</p>
  
  <p>Any help would be much appreciated. Thanks!</p>
