How do I find if an element contains a specific class with jQuery?

Question

I need to check if an element contains a certain child class using JQUERY.

I tried:

if ($('#myElement').has('.myClass')) {
   do work son
}

Didn't work.

My html code is laid out like this:

<div id="myElement">
    <img>
    <span>something</span>
    <span class="myClass">Hello</span>
</div>

The easiest way would be to search for .myClass as a child of #myElement:

if($('#myElement .myClass')).length > 0)

If you only want first level children, you'd use >

if($('#myElement > .myClass')).length > 0)

Another way would be passing a selector to find and checking for any results:

if($('#myElement').find('.myClass').length > 0)

Or for first level children only:

if($('#myElement').children('.myClass').length > 0)
