[jQuery] An easy question: Selecting DOM nodes that doesn't have class "active"


Hi, I have this code:
<ul>
<li>
<ul class="menu">
<li>...</li>
</li>
<li>
<ul class="menu active">
<li>...</li>
</li>
<li>
<ul class="menu">
<li>...</li>
</li>
</ul>
I want to set css property display:none to all the elements that are
not active.
I'm looking at the doc on ":not" selector, I've tried:
$(':not(.active)').css({'display:none'});
But doesn't works... Where I'm doing wrong?
Thank you
