Hi Jack,
Not silly at all.
You don't need to include more about the elements, but beginning with
the tag name may result in faster selector performance than starting
with the name attribute.
Please note, though, that your first expression should not have the
spaces in between the selector parts. Also, you're missing a trailing
single quote, and the double quotes aren't necessary. So instead of
this:
$('input :radio [name="xxx"]:checked)
it should be this:
$('input:radio[name=xxx]:checked')
If I were using this in a script, I'd probably drop the :radio part.
Since I wouldn't have a different type of input with the same name,
there would be no reason to filter against that.
$('input[name=xxx]:checked)
Hope that helps.

Hi, all
For selector do I need to qualfy more about the elements I want to
select? For example:
$('input :radio [name="xxx"]:checked)
does it better than the following
$([name="xxx"]:checked)
Thank you in advance!
