I think what's confusing to me as a n00b is that "if" does not seem to
be closed.  How would I accomplish an else condition?


I highly recommend to make yourself familiar with JavaScript control 
structures. jQuery can do a lot for you but you still need to know the 
basics of JavaScript...

What do mean by "not closed"?

You can use an if statement without curly braces if there's only one
statement to be executed:

if (condition) alert('yes');

or

if (condition)
    alert('yes');

Together with else:

if (condition) alert('yes');
else alert('no');

I tend to always use curly braces, that makes it easier to add another 
line to the conditional blocks and to me it's easier to read, but that's 
just a personal taste I guess. You'll need them anyway to group multiple 
statements in a block:

if (condition) {
    alert('yes');
    alert('I said yes');
} else {
    alert('no');
    alert('I said no');
}

Back to your example:

$("a.saveConfig").click(function() {
    if ($('div.detail').is(':visible')) {
        alert('Hey this works');
    } else {
        alert('Hey this doesn't work');
    }
});
