S2C Home « Selectors « :radio
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 DOMquerySelectorAll()
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.

Selects all elements of type radio.
In the example below we apply a red border to radio elements within the form.
$(function(){
$('.ourform').submit(function () { return false; }); // disable submit
$('#btn1').on('click', function() {
$('form input:radio').wrap('<span></span>')
.parent().css('border', '1px solid red');
});
});
