How do I use javascript to tell me which link brought me to my current page?

Hi,

I have a home page with basic links to anchored sections of a second page.

On the second page i have some content which contains a variety of functions that will run depending on which link the user clicked from the home page.

My question is what javascript can I use on the second page which will identify the link used from the home page.

Thank you

 

<script type='text/javascript'>
  document.write(document.referrer);
</script>

Code (markup):

Sometimes it shows nothing because visitors can stop their browsers from sending the referrer value.

 

Thanks for that - i'm experimenting with parsing a query string on my anchored links. Will update.
