window.location = #anchor doesn't work in IE

On this map:

http://web.pacific.edu/documents/marketing/campus-map/version%202/stockton-campus-2.0.htm

I have an anchor at the top, and I want the page to jump to the anchor when a link is clicked.

I'm currently using 

window.location = '#top';

It works as expected in FF, Opera, and Chrome, but not in IE 7.

I've tried all permutations like window.location.hash and window.location.assign() and also scrollIntoView(true) and focus().

How can I make it work in IE?

Edit: Nothing seems to work, which makes me think it's not the syntax, but something about the JS... here is the click event handler... could it be because it returns false? I'm grasping at straws. 

// Click handler for each location link
$('#index a').click(function()
{
    hideMarkers();
    location.href = location.href + "#top";
    var marker = showMarker( $(this).attr('data-id') );
    GEvent.trigger( marker, "click" );
    return false;
});

Edit: Assignment to window.location.hash breaks in IE7 and IE8 on pages that were loaded as a result of page redirection via the HTTP "Location" header. The solution is to return a page with Javascript that itself will perform the redirection. See the answer by Joe Lapp.

You have to check for hash before appending it. I did it with this,

window.location = ((location.href).indexOf('#') == -1 ? location.href + "#top" : location.href);

I have this code in production and it works fine in IE7...

location.hash = "#top";

However, if you are just trying to scroll to the top, this ought to be a lot easier...

window.scrollTo(0, 0);

I also had a problem with windows.location.hash working in all browsers but IE7 and IE8 (at least on Vista). After much experimenting, I discovered that page redirection was breaking hash assignment.

An error will occur in IE7 or IE8 if you assign a value to windows.location.hash from within a page that was loaded as a result of redirection via the HTTP "Location" header.

After discovering this, I was able to find a fix elsewhere on StackOverflow (see here). The solution is to have the browser redirect via Javascript. Here I repost the solution from the other StackOverflow page:

<html>
<head>
    <meta http-equiv="refresh" content="0; url=__REDIRECT_LOCATION__">
    <script>window.location = "__REDIRECT_LOCATION__";</script>
</head>
</html>

This would explain why some people were having a problem with setting hash and some were not, but I do not know that the originator of the thread was redirecting.

I should also point out that I couldn't just use scrollTo() because my purpose was to remove the hash tag from the address bar without reloading the page, not to scroll.

The location object is broken up into several properties - href is only one of them

Another one, hash, is what you're looking for.

top.location.hash = 'top';

You can also do this without using the location/href at all - just use scrollTo()

top.scrollTo( 0, 0 );

location.href = location.href.split("#")[0] + "#top"

EDIT: to avoid the possibility of ever having two hashes.

window.location.href = '#top';

And if this doesn't work, try the full URL

window.location.href = 'http://domain.com/my.html#top';
