I am trying to get value of radio group with name managerelradio. My html code for this radio group is.

Jquery 是这样的..

and Jquery for this is..

    var manageradiorel = $('input[name = "managerelradio"]:checked' , '#managechildform').val();
 alert(manageradiorel);

它显示我未定义.

虽然我也试过了.

 var manageradiorel = $('input[name = "managerelradio"]:checked').val();
 alert(manageradiorel);

但我仍然得到未定义的值.

But still I am getting undefined value.

var manageradiorel = $("input:radio[name ='managerelradio']:checked").val();
alert(manageradiorel);
