javascript - Using jQuery to select/deselect radio buttons with different names -

i have quiz uses ids of answers in db name in order check if they're correct. can't make them same name.

anyways leaves me radio buttons can checked , isn't how should work. found jquery allows radio buttons unchecked need them uncheck when click other buttons.

html:

<fieldset>     <input type="radio" name="21">     <label for="21">answer 21</label>     <input type="radio" name="22" class="checked">     <label for="22">answer 22</label>     <input type="radio" name="23" class="">     <label for="23">answer 23</label>     <input type="radio" name="24">     <label for="24">answer 24</label> </fieldset> 

script:

    $("input[type='radio']").click(function (event) {     // if button selected.     if ($(this).hasclass("checked")) {         // remove placeholder.         $(this).removeclass("checked");         // , remove selection.         $(this).removeattr("checked");         // if button not selected.     } else {         // remove placeholder other buttons.         $("input[type='radio']").each(function () {             $(this).removeclass("checked");         });         // , add placeholder button.         $(this).addclass("checked");     } }); 

so if 21 checked , click 22, 21 should uncheck

if want group of radios inside same fieldset act radio group can do

 $("input[type='radio']").click(function (event) {      $(this).addclass("checked");          $(this).siblings('input[type="radio"]').prop('checked', false).removeclass('checked')  });
