[jQuery] how to catch the value of div container

[jQuery] how to catch the value of div container


Hi All,
In HTML code:
<div id="DIV_01">
<ul>
    <li><a href="#">list_01</a>
        <ul>
            <li><a href="#">LIST_01_00</a></li>
.............................
        </ul>
    </li>
</ul>
</div>
When I click in list element (ese. LIST_01_00)
In jQuery code, I would like to catch the “id value” (DIV_01) of "div
container".
$(this).click( function() {
    ?????
}
Any ideas?
Thanks,
Antonio
