html - jQuery addClass to ul children only -

i have this

<ul>    <li class="quiddam">      <a href="">lorem</a>      <ul>        <li><a href="">ipsum</a></li>        <li><a href="">dolores</a></li>      </ul>    </li> </ul> 

if use jquery add class of "brimsom" children of class "quiddam" this:

$(".quiddam").children().addclass("brimsom"); 

both tag , ul tag children class of "brimsom".

how can add class of "brimsom" children of "quiddam" ul tag only?

both tag , ul tag children class of "brimsom".

that's not correct.

the following code snippet add class "brimson" elements have "quiddam" class, not children elements.

$(".quiddam").addclass("brimsom"); 

therefore:

<li class="quiddam brimson"> 

---

the following script add them children elements:

$(".quiddam *").addclass("brimsom"); 

---

however, require ul children, be:

$(".quiddam ul").addclass("brimsom"); 

therefore:

<li class="quiddam">      <a href="">lorem</a>      <ul class="brimson">
