Seven the element's class to empty. 

// Pega o primeiro li e remove a classe
document.getElementsByName("li")[0].className = "";

If you want to keep some class, reset the class: 

document.getElementsByName("li")[0].className = "";
document.getElementsByName("li")[0].className = "classe_que_fica";

I hope I have helped!

Any questions, just leave a comment.
