JavaScript Not able to set focus to first li element within ul

Question

I have below code:

<ul id='someId'>
 <li class='someClass'>
 </li>
</ul>

I want to set focus on first li element within ul based on some condition.

My first attempt is like this:

var ul = document.getElementById('someId');           
var child = ul.childNodes[0];
child.focus();

My second attempt is like this :

var y = document.getElementsByClassName('someClass');
var aNode = y[0];
aNode.focus();

But none of the above works

Any ideas?

The problem is that you can't focus a non input element without setting tabIndex.

<li tabIndex="-1">...</li>
