Change base href using javascript

Question

Can I change the href by javascript?

I use the following code in but it doesn't work:

<base href="/" />
<script type="text/javascript"> 
function setbasehref(basehref) { 
 var thebase = document.getElementsByTagName("base"); 
 thebase[0].href = basehref; 
} 
//setbasehref("/");
setbasehref("http://newurl.com");
</script> 

Answer 1

This line:

document.getElementsByTagName("base"); 

Do you have an element of type "base"?

Perhaps you could try grabbing the element by its ID attribute?

 document.getElementById("YourHyperlinksID"); 

Good luck
