checked radio button by name in jquery

Question

Does anyone know how can I checked a radio button by using the name instead of id in jquery?

Answer 1

$('input:checkbox[name=someName]').attr('checked', 'checked');

Answer 2

generally, attribute-based selectors take the form

[name op pattern]

(including the brackets) where name is the name of the attribute, op is a relational operator, and pattern is matched against the attribute's value. see Attribute Filters in the docs
