:radio Selector
radio selector
version added: 1.0jQuery(':radio')
Description: Selects all elements of type radio.
$(':radio') is equivalent to $('[type=radio]'). As with other pseudo-class selectors (those that begin with a ":") it is recommended to precede it with a tag name or some other selector; otherwise, the universal selector ("*") is implied. In other words, the bare $(':radio') is equivalent to $('*:radio'), so $('input:radio') should be used instead.
To select a set of associated radio buttons, you might use: $('input[name=gender]:radio')
Example:
Finds all radio inputs.
