Example

This example sets the base URL of the document to a reference folder. Internet Explorer uses the BASE element to resolve the link to http://msdn.microsoft.com/workshop/author/dhtml/reference/properties/href_2.asp.
<HEAD>
<BASE HREF="http://msdn.microsoft.com/workshop/author/dhtml/reference">
</HEAD>

<BODY>
Click <A HREF="properties/href_2.asp">here</A> to learn about the 
href property.
</BODY>
This example retrieves the base URL from the document if a valid BASE element is specified in the document. Otherwise, the function returns null.
<SCRIPT>
function GetBase()
{
    var oBaseColl = document.all.tags('BASE');
    return ( (oBaseColl && oBaseColl.length) ? oBaseColl[0].href : 
        null );
}
</SCRIPT>
