You can also try this:

Returns whatever is in your href...
Actually, in IE, where I'm guessing the problem is occurring, you need
to set the iFlags argument to 2 in order to get the actual value of
the href attribute.
From MSDN [1]:
iFlags Optional. Integer that specifies one or more of the
following flags:
0 Default. Performs a property search that is not case-sensitive, and
returns an interpolated value if the property is found.
1 Performs a case-sensitive property search. To find a match, the
uppercase and lowercase letters in sAttrName must exactly match those
in the attribute name. If the iFlags parameter for getAttribute is set
to 1 and this option is set to 0 (default), the specified property
name might not be found.
2 Returns the value exactly as it was set in script or in the source
document.

In this case, it would be:
$('#testlink')[0].getAttribute('href', 2);
One more reason to just use the jQuery method -- so we don't have to
worry about such cross-browser silliness.

Here's the short version:
I have a link:
<a id="testlink" href="page.html">page.html</a>
But when I do this:
alert($('#testlink')[0].href);
I get this:
http://localhost/page.html
How do I get the *actual* HREF of the link ("page.html"), and not the
mangled version?
Thanks!
----------
The long version:
I have a few links in HTML:
<a href="/page1.html">/page1.html</a>
<a href="http://localhost/page1.html";>http://localhost/page1.html</
a>
<a href="http://localhost:80/page1.html";>http://localhost:80/
page1.html</a>
<a href="http://localhost/page2.html";>http://localhost/page2.html</
a>
<a href="http://www.google.com/page1.html";>http://www.google.com/
page1.html</a>
When I do this:
$("[href]").each(function() {
var matches = $("[href='" + this.href + "']");
console.log("Searching for HREF \"" + this.href + "\", text
\"" + $(this).html() + "\"" );
matches.each(function() {
console.log("Found: HREF \"" + this.href + "\", text \"" +
$(this).html() + "\"" );
});
});
I get this:
Searching for HREF "http://localhost/page1.html";, text "/
page1.html"
Found: HREF "http://localhost/page1.html";, text "http://localhost/
page1.html"
Searching for HREF "http://localhost/page1.html";, text "http://
localhost/page1.html"
Found: HREF "http://localhost/page1.html";, text "http://localhost/
page1.html"
Searching for HREF "http://localhost/page1.html";, text "http://
localhost:80/page1.html"
Found: HREF "http://localhost/page1.html";, text "http://localhost/
page1.html"
Searching for HREF "http://localhost/page2.html";, text "http://
localhost/page2.html"
Found: HREF "http://localhost/page2.html";, text "http://localhost/
page2.html"
Searching for HREF "http://www.google.com/page1.html";, text
"http://www.google.com/page1.html";
Found: HREF "http://www.google.com/page1.html";, text "http://
www.google.com/page1.html"
The problem is that elem.href is returning a mangled version of the
HREF, but the [href='...'] selector requires the URL exactly as it is
written in the HTML. So when an element has "/page.html" as it's
HREF, doing elem.href returns "http://localhost/page.html"; instead.
So to search for the "/page.html" HREF, I have to search for:
[href='page.html']
[href='/page.html']
[href='http://localhost/page.html']
[href='http://localhost:80/page.html']
[href='https://localhost/page.html']
[href='https://localhost:443/page.html']
Where "localhost" and "80" must be determined by javascript at
runtime
to reflect the current server and port. Also, the "/page.html" and
"page.html" are not comprehensive. The javascript would also have to
check for all permutations of "../page.html", "folder/../page.html",
etc. The root of the problem here is this: how can I get the
*actual* HREF of a link via javascript, and not the mangled version?
