Answer 1

Assuming your structure is like this:

<div id="parent">
    <textarea class="expand"></textarea>
</div>

You can simply do this:

$('#parent > textarea[class*=expand]');

> is the child selector and #idselects the element with the given id.

Edit

As @VijayVerma stated in the comments: If your <div> doesn’t have an ID yet, just add the ID to the textarea instead:

<textarea id="onlyme" class="expand"></textarea>

And select it with the ID-selector only:

$('#onlyme');

If your <div>s already have IDs, you’re fine with the first solution I’ve posted.
