Trying to figure out a way to use Javascript to set up a little

  • 0

Trying to figure out a way to use Javascript to set up a little if-else statement using only part of the url to determine if a link should go one place or another. So far what I got is, 

 <script type="text/javascript">
    if (url.indexOf("example.com/") != -1) 
{
        <a href="placeone.com" target="_blank">Blahblah</a>
    } else {
        <a href="placetwo.com" target="_blank">Blahblah</a>
        }
 </script>

The problem is that the link doesn’t even appear so I don’t know how wrong or not I am.

Thanks for any help.

Edit: Lets just say for the sake of argument it is a blank html page. As in <html>
<body>
</body>
</html>

Looking for more of a proof of concept then branch out into getting this working on a full scale site.

Edit #2:
Figured it out, even has url detection. 

<a id="link">link</a>
<script type="text/javascript">
var link = document.getElementById('link');
var referrerUrl = document.referrer;
if (referrerUrl.indexOf("searchurlfor") != -1)
{
    link.href = "place1";
} else {
    link.href = "place2";
}
</script>

    You need getElementById

    HTML:

    <a id="link">link</a>

    Javascript

    <script type="text/javascript">
var link = document.getElementById('link');
if (url.indexOf("example.com/") != -1) 
{
        link.href="placeone.com";
} else {
        link.href="placetwo.com";
}
 </script>
