You may want to read this extensive (and rather intensive) discussion
on this very question here:
<http://groups.google.com/group/comp.lang.javascript/browse_frm/thread/4d2e99b2a8bdbbd2/b595a7a81b0a62a3>

<a href=""> and <a href="#"> will lead to page shift/scroll if the page
is long enough on older browsers.

Of the listed options, this is the _worst_.
There is no reason to use this as opposed to:
<a href="javascript_required.html" onClick="myFunction(); return
false;">link</a>

Why would you want to have an empty link?
> <a href="">
This is a reference to the document itself.
> <a href="#">
This is a reference to the start of the current document.
> <a href="javascript:void(0);">
This is undefined; javascript: URLs are unregistered.
You could create a self-referencing link, too:
<a name="foo42" href="#foo42">
I suppose you want to have an "empty" link so that you can make something
clickable, triggering some scripted events, without making it a link.
The simple answer is: don't.
Make it a link that points to an address that contains a useful replacement
for the functionality, if it is relevant.
<a href="#nojs" onclick="foo(); return false">
. . .
<h2 id="nojs">Something</h2>
<p>Put here something useful.</p>
If your piece of HTML code has been _generated_ with JavaScript, so that the
element does not appear if JavaScript is off, use href="#" but make sure your
event handler returns false, so that the href will never be used (it could be
harmful if it caused a movement to the start of the document).
