Navigate Anchor Links Using A Button Onclick Event?

I am wondering if it is possible to navigate anchor links using a button onclick event. I want next and previous hit buttons to navigate the already existing hits (#hit1, #hit2, etc.).For instance, I have:

<script type="text/javascript">
var numHits = {HITS}-1;
function nextHit(){[code]....

I have seen working examples with the href tag (e.g. <a href="#" onclick="func();return false">), but nothing with buttons. I also can't seem to get the working href examples to work on my server.For instance, I cannot get this code to work, it just goes to js_required.html:

<a href="js_required.html" onclick="doSomething(); return false;">go</a>
function doSomething(){
alert("test");
}
