radio button - Change radiobutton multiple times using jQuery -

-

i can't seem change between radio buttons correctly using jquery. bug in jquery? example here: http://jsbin.com/yafik/1/edit

code jsbin:

<input type="radio" name="test"> <input type="radio" name="test"> <input type="radio" name="test"> <input type="radio" name="test">  <script>     $("input").eq(1).attr("checked", true);     $("input").eq(2).attr("checked", true);     //$("input").attr("checked", false);     $("input").eq(1).attr("checked", true); </script>

you can try uncomment third line: $("input").attr("checked", false);, i'd expect reset checked attributes.

i expect set second radiobutton checked. if @ source code, both second , third radiobuttons checked.

use .prop() boolean values

$("input").eq(1).prop("checked", true); $("input").eq(2).prop("checked", true); $("input").eq(1).prop("checked", true);
