[jQuery] How to determine radio button state?

[jQuery] How to determine radio button state?


I'd like to show or hide a table row depending on whether a certain radio
button is checked.
I can not use a $(theRadioButton).click( ... ) handler for several reasons.
One of them is that I need to check the state when the page loads and show
or hide the element accordingly.
I'm selecting the radio button like this:
$('input', 'div#hide3aButton')
That code does seem to successfully select the button. Now I need to find
out if it's checked I tried this:
if ($('input', 'div#hide3aButton').checked) { ... }
but it seem to always be false regardless of the state of the radio button.
Any help would be greatly appreciated.
Thanks.
