document.referrer in JS

**hpl** · Apr 2nd, 2002, 03:50 AM

I want to use the object document.referrer because I need some information on the URL I have visited before the actual site. I have used this function where I want to write my previous site to a text field, but nothing happens. What could be wrong?

Code:

function tester() {
	if (document.referrer == "http://intranet") {	
		sprog = "Not OK";
		document.calc_heat.test.value=sprog;
		} 
	else {
		sprog = document.referrer ;
		document.calc_heat.test.value=sprog;
		} 
	
}

Hi,

I take it the form is called calc_heat and the text field is called test?

I tested it using your code and worked fine for. Bearing in mind that it was run from a webserver, it will return nothing if its run from a folder.

If you put an Alert(document.referrer) in the code does it still return nothing?

This is what I used...

page 1 code

Code:

<html>
  <head>
    <title>Untitled</title>
  </head>
  <body>
    <a href="page2.htm">Page2</a>
  </body>
</html>

page 2 code

Code:

<html>
  <head>
    <title>Untitled</title>
    <script language="JavaScript" type="text/javascript">
    <!--
       function tester() {
	if (document.referrer == "http://intranet") {	
		sprog = "Not OK";
		document.calc_heat.test.value=sprog;
		} 
	else {
		sprog = document.referrer ;
		document.calc_heat.test.value=sprog;
		} 
	
      }
    //-->
</script>

</head>
<body onload="tester()">
<form name="calc_heat">
   <input type="text" name="test">
</form>
</body>
</html>
