Question

$(this).parent().find('> ul')

What is this selecting, I don’t really understand what the jquery API is saying on the find() function.

Answer 1

It moves from the targeted element ($(this)) to the parent, and then selects all ul elements that are immediate children (not just descendants) of that parent element. Effectively, then, it just selects sibling elements of the current element, and is equivalent to:

$(this).siblings('ul');

Incidentally, the jQuery API is awesome for reading about jQuery methods. To find information about something use the URL http://api.jquery.com/ and then append the method that you want to find out about.

So, if you want to read about siblings(), the URL becomes: http://api.jquery.com/siblings/.
