$(".outerDiv").hover(
function(){ $(this).find(".innerDiv").show(); },
function(){ $(this).find(".innerDiv").hide(); }
);

What the above code does is show <div class="innerDiv"></div> when <div class="outerDiv"></div> is hovered, and return the innerDiv to a hidden state when the the hover is lost.

I found this useful to show edit and delete links when a user hovered over a particular database item.

The following examples are variations (not the actual because I could get in trouble here at work) of what I was able to do off the top of my head:

/^p\d{3}$/ // looks for a “p” followed by 3 digits
/^\d{6}(-\d{6})?$/ // looks for 6 digits with an optional dash then 6 more digits

Just thought I’d share in my own joy. Can you see the joy in those regex? Love it.

Note: I fixed the second example per Mitch’s bug find. Apparently my transcription from my whiteboard was not perfect. :-)
