Question

Please help me figure out how to add a class to li where an anchor is present.

<ul>
    <li>abc</li>
    <li>abc</li>
    <li><a>abc</a></li>
    <li><a>abc</a></li>
    <li>abc</li>
</ul>

I want to add a class to first li where anchor tag is present within the ul

Answer 1

Assuming I’ve understood what you mean, try this:

$("LI").has("A").filter(":first").addClass("foo");

Fiddle to show it works

EDIT

This works too, and should be a little faster:

$("LI A:first").closest("LI").addClass("foo");
