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.

<form> <input type="button" value="Input Button"/> <input type="checkbox" /> <input type="file" /> <input type="hidden" /> <input type="image" /> <input type="password" /> <input type="radio" name="asdf" /> <input type="radio" name="asdf" /> <input type="reset" /> <input type="submit" /> <input type="text" /> <select><option>Option<option/></select> <textarea></textarea> <button>Button</button> </form> <div> </div>
CSS:
textarea { height:25px; }
Code:
var input = $("form input:radio").wrap('<span></span>').parent().css({background:"yellow", border:"3px red solid"}); $("div").text("For this type jQuery found " + input.length + ".") .css("color", "red"); $("form").submit(function () { return false; }); // so it won't submit
