Let's say I have a simple list:

  <ul>
    <li class="notClicked">1</li>
    <li class="notClicked">2</li>
    <li class="notClicked">3</li>
  </ul>

Can I onClick of one "li" change styles of all li's except the one clicked?

So if I click "li" number 2, then the list will look like:

  <ul>
    <li class="notClicked">1</li>
    <li class="clicked">2</li>
    <li class="notClicked">3</li>
  </ul>

So if I click on first "li" then it will have clicked class, while others will be notClicked.

In case you want to play with it, here's jsbin: http://jsbin.com/ucuca4/edit

Make either in Prototype or plain JavaScript.

Why change the style of the other? You may want to change the style of the clicked element.

If so, you can use jQuery for that

Example:

<li class = "notClicked">element 1</li>
<li class = "notClicked">element 2</li>
<li class = "notClicked">element 3</li>

$('.notClicked').click(function()
{
    $(this).addClass('active');
});

<script>
    function changeClass(){
        document.getElementById("idElement").setAttribute("class", "Clicked");
    }
</script>

<ul>
    <li class="notClicked" >1</li>
    <li class="notClicked" onClick="changeClass()" id="idElement">2</li>
    <li class="notClicked">3</li>
</ul>
