proper way to assign onclick of <a> tag

[sneakyimp]

I put together a site several years ago and assigned javascript to onclick events like so:

<a href="#" onclick="document.majors_search.submit()">

Today it doesn't work in Firefox 3.0.13 for some reason. It just keeps navigating to the current page with an empty anchor, i.e., the url goes from http://domain.com/page.php to http://domain.com/page.php#.

OK so I managed to try this solution and it seems to work:

<a href="#" onclick="document.majors_search.submit(); return false;">

By returning 'false' in the onclick, we apparently tell the browser not to handle the click as a navigational directive. This works in firefox...can't help but wonder if it works every where else.
