获取所有无线电:

var radios = $("input[type='radio']");

过滤器来获取被选中的一个

radios.filter(":checked");

OR

另一种找到单选按钮值的方法

var RadeoButtonStatusCheck = $('form input[type=radio]:checked').val();

    <input type="radio" name='s_2_1_6_0' value='Mail copy to my bill to address' id = "InvCopyRadio" onchange = 'SWESubmitForm(document.SWEForm2_0,s_4,"","1-DPWJJF")' style="height:20;width:25" tabindex=1997 >

$(function() {
      $("#submit").click(function() {
        alert($('input[name=s_2_1_6_0]:checked').val());
      });
    });`

举个例子

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1  /jquery.min.js"></script>
<form id="myForm">
<input type="radio" name="radio" value="first"/> 1 <br/>
<input type="radio" name="radio" value="second"/> 2 <br/>
</form>



<script>
$(document).ready(function () {
    $('#myForm').on('click', function () {
        var value = $("[name=radio]:checked").val();

        alert(value);
    })
});
</script>

 <div class="col-md-12">
   <div class="form-radio">
       <input class="radio-outlined" id="accept_new_login1" type="radio" name="aNL" value="1">
       <label for="accept_new_login1" class="radio-teal">Yes</label>
        <input class="radio-outlined" id="accept_new_login2" type="radio" name="aNL" value="0">
        <label for="accept_new_login2" class="radio-teal">No</label>
   </div>
</div>

<script>
  $("input[name=aNL]").on("click" , function () {
    console.log("test" ,$("#accept_new_login").val() , this.value , this.id );
  })

 </script>

这个解决方案不仅简单，还告诉选择的ID和值。你可以检查我的输出。

另一种理解…工作:

HTML代码:

 <input type="radio" name="active_status" class="active_status" value="Hold">Hold 
 <input type="radio" name="active_status" class="active_status" value="Cancel">Cancel 
 <input type="radio" name="active_status" class="active_status" value="Suspend">Suspend

Jquery代码:

$(document).on("click", ".active_status", function () {
 var a = $('input[name=active_status]:checked').val();  
 (OR)   
 var a = $('.active_status:checked').val();
 alert(a);
});

我知道我这么晚才加入。但值得一提的是，它需要

<label class="custom-control-label" for="myRadioBtnName">Personal Radio Button</label>

然后我在js中检查了这个。可以是这样

$(document).ready(function () { 

$("#MyRadioBtnOuterDiv").click(function(){
    var radioValue = $("input[name=myRadioButtonNameAttr]:checked").val();
    if(radioValue === "myRadioBtnName"){
        $('#showMyRadioArea').show();
    }else if(radioValue === "yourRadioBtnName"){
        $('#showYourRadioArea').show();
    }
});
});
