How do I prevent anchor tags for ajax requests from going to the top of the page?

This seems like a stupid question, but I can't figure it out. I have some anchor tags on my page that perform ajax functions only, and have no inherent use except for triggering javascript:

 <a href="#" onclick="SomeFunction();">Blah</a>

How do I prevent clicking on this link from scrolling all the way to the 开发者_运维知识库top of the page. It is causing some annoying UI usability issues.

HTML

<a href="javascript:void(0);" id="theLink" onclick="SomeFunction();">Blah</a>

JS

//jQuery
$('#theLink').click(function(){
    doSomething();
});

//Regular JS
document.getElementById("theLink").onclick = doSomething;

Specify a non existing anchor such as <a href="#nogo" onclick="SomeFunction();">Blah</a>

Add return false to your SomeFunction() to the very end :)

var SomeFunction = function(){
    //AJAX MAGIC
    return false;
}
