[jQuery] Jquery index question

[jQuery] Jquery index question


I have a HTML list:
<ul class="buttons">
<li><a href="#" class="active">Home</a></li>
<li><a href="#">About</a></li>
<li><a href="#" class="active">News</a></li>
</ul>
I want to obtain the index only for the elements with class="active".
For example I want to create an array with value "0" for Home and "2"
for News (the indexes).
Is possible to do this with jquery?
Thanks!
