:radio Selector

Categories: jQuery Extensions | Form

jQuery(':radio')

Description: Selects all elements of type radio.

  • jQuery(':radio')

    version added: 1.0

$(':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')

Note:

Because :radio is a jQuery extension and not part of the CSS specification, queries using :radio cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. For better performance in modern browsers, use [type="radio"] instead.
  • Finds all radio inputs.
