Form radio selector.

Shorthand version $(':radio')

Description

The :radio selector, selects all elements of type radio.

• Being a jQuery extension the :radio pseudo selector is not part of any current CSS specification. Therefore :radio cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method.
• The same results can be achieved using the Attribute Equals Selector via $('[type=radio]'), without the hit to performance.
• If this selector is not preceded by another selector, the universal selector ("*") is implied and so the whole DOM will be searched. Use another selector as in the example below to narrow the search and improve performance.

Syntax

Parameters

None.

Return

N/A.

:radio Example Selectors  <<  Top

Selects all elements of type radio.

In the example below we apply a red border to radio elements within the form when the button is clicked.

$(function(){
  $('.ourform').submit(function () { return false; }); // disable submit 
  
  $('#btn1').on('click', function() {
    $('form input:radio').wrap('<span></span>')
                         .parent().css('border', '1px solid red');
  });
});
