Identifying a DOM by something other than id (ie: it's href tag) in jquery

Question

The title covers most of my question. Instead of:

$('#id').slideUp();

I need to be able to select a particular area tag in an image map in a similar way, by virtue of the string in its href tag. I'm sure this involves the .attr() function but in what way I don't know.
Could a resident genius help me please. Many thanks.

$('[href="something"]').slideUp();

Check out the attribute selectors:-

$("[href='whatever']").slideUp();
