JQuery - Set Attribute value

Question

I have following HTML with two elements having the same name

Answer 1

"True" and "False" do not work, to disable, set to value disabled.

$('.someElement').attr('disabled', 'disabled');

To enable, remove.

$('.someElement').removeAttr('disabled');

Also, don't worry about multiple items being selected, jQuery will operate on all of them that match. If you need just one you can use many things :first, :last, nth, etc.

You are using name and not id as other mention -- remember, if you use id valid xhtml requires the ids be unique.
