radio selector
Description: Selects all elements of type radio.
version added: 1.0jQuery( ":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" )
Additional Notes:
- Because
:radiois a jQuery extension and not part of the CSS specification, queries using:radiocannot take advantage of the performance boost provided by the native DOMquerySelectorAll()method. For better performance in modern browsers, use[type="radio"]instead.
Example:
Finds all radio inputs.
