jQuery is based on "find something -> do something". The "find something"
is largely done with selectors (similar to CSS selectors).
you want to find the element with the id="test". that would be $('#test')
you want it to do something when that element receives a blur event...
$('#test').blur(); <-- that's the event, but it's not doing anything yet.
To do something, pass a function to the blur():
$('#test').blur(function() { });
which, when fleshed out a little more, might look like:
$('#test').blur(function() {
alert('I just got blurred!');
});
While inside these "inner functions", you have a handle on the element that
triggered it. It's referred to as $(this). You can also use "plain ol'
javascript" and use 'this' (no quotes). Depends on what you're doing with
it.
$('#test').blur(function() {
alert(this.id);
alert($(this).attr('id')); // they do the same thing
});
Most of this (if not all of it) is covered in the docs.

I have failed as much as I have succeeded. But I love my life. I love my
wife. And I wish you my kind of success.
