javascript - value - radio button checked condition in jquery

How can I know which radio button is selected via jQuery? (20)


<script src=""></script>
         <td>Sales Promotion</td>
         <td><input type="radio" name="q12_3" value="1">1</td>
         <td><input type="radio" name="q12_3" value="2">2</td>
         <td><input type="radio" name="q12_3" value="3">3</td>
         <td><input type="radio" name="q12_3" value="4">4</td>
         <td><input type="radio" name="q12_3" value="5">5</td>
<button id="submit">submit</button>

I have two radio buttons and want to post the value of the selected one. How can I get the value with jQuery?

I can get all of them like this:

$("form :radio")

How do I know which one is selected?

Also, check if the user does not select anything.

var radioanswer = 'none';
if ($('input[name=myRadio]:checked').val() != null) {           
   radioanswer = $('input[name=myRadio]:checked').val();

Another way to get it:

 $("#myForm input[type=radio]").on("change",function(){
   if(this.checked) {
<script src=""></script>
<form id="myForm">
   <span><input type="radio" name="q12_3" value="1">1</span><br>
   <span><input type="radio" name="q12_3" value="2">2</span>

From this question, I came up with an alternate way to access the currently selected input when you're within a click event for its respective label. The reason why is because the newly selected input isn't updated until after its label's click event.


$('label').click(function() {
  var selected = $('#' + $(this).attr('for')).val();


$(function() {
  // this outright does not work properly as explained above
  $('#reported label').click(function() {
    var query = $('input[name="filter"]:checked').val();
    var time = (new Date()).toString();

    $('.query[data-method="click event"]').html(query + ' at ' + time);

  // this works, but fails to update when same label is clicked consecutively
  $('#reported input[name="filter"]').on('change', function() {
    var query = $('input[name="filter"]:checked').val();
    var time = (new Date()).toString();

    $('.query[data-method="change event"]').html(query + ' at ' + time);

  // here is the solution I came up with
  $('#reported label').click(function() {
    var query = $('#' + $(this).attr('for')).val();
    var time = (new Date()).toString();

    $('.query[data-method="click event with this"]').html(query + ' at ' + time);
input[name="filter"] {
  display: none;
#reported label {
  background-color: #ccc;
  padding: 5px;
  margin: 5px;
  border-radius: 5px;
  cursor: pointer;
.query {
  padding: 5px;
  margin: 5px;
.query:before {
  content: "on " attr(data-method)": ";
[data-method="click event"] {
  color: red;
[data-method="change event"] {
  color: #cc0;
[data-method="click event with this"] {
  color: green;
<script src=""></script>
<form id="reported">
  <input type="radio" name="filter" id="question" value="questions" checked="checked">
  <label for="question">Questions</label>

  <input type="radio" name="filter" id="answer" value="answers">
  <label for="answer">Answers</label>

  <input type="radio" name="filter" id="comment" value="comments">
  <label for="comment">Comments</label>

  <input type="radio" name="filter" id="user" value="users">
  <label for="user">Users</label>

  <input type="radio" name="filter" id="company" value="companies">
  <label for="company">Companies</label>

  <div class="query" data-method="click event"></div>
  <div class="query" data-method="change event"></div>
  <div class="query" data-method="click event with this"></div>

Here's how I would write the form and handle the getting of the checked radio.

Using a form called myForm:

<form id='myForm'>
    <input type='radio' name='radio1' class='radio1' value='val1' />
    <input type='radio' name='radio1' class='radio1' value='val2' />

Get the value from the form:

$('#myForm .radio1:checked').val();

If you're not posting the form, I would simplify it further by using:

<input type='radio' class='radio1' value='val1' />
<input type='radio' class='radio1' value='val2' />

Then getting the checked value becomes:


Having a class name on the input allows me to easily style the inputs...

I use this simple script

$('input[name="myRadio"]').on('change', function() {
  var radioValue = $('input[name="myRadio"]:checked').val();        

I've released a library to help with this. Pulls all possible input values, actually, but also includes which radio button was checked. You can check it out at

It'll give you a js object of the answers, so a form like:

<input type="radio" name"favorite-color" value="blue" checked> Blue
<input type="radio" name="favorite-color" value="red"> Red

will give you:

  "favorite-color" : "blue"

If you already have a reference to a radio button group, for example:

var myRadio = $("input[name=myRadio]");

Use the filter() function, not find(). (find() is for locating child/descendant elements, whereas filter() searches top-level elements in your selection.)

var checkedValue = myRadio.filter(":checked").val();

Notes: This answer was originally correcting another answer that recommended using find(), which seems to have since been changed. find() could still be useful for the situation where you already had a reference to a container element, but not to the radio buttons, e.g.:

var form = $("#mainForm");
var checkedValue = form.find("input[name=myRadio]:checked").val();

If you only have 1 set of radio buttons on 1 form, the jQuery code is as simple as this:

$( "input:checked" ).val()

If you want just the boolean value, i.e. if it's checked or not try this:


In my case I have two radio buttons in one form and I wanted to know the status of each button. This below worked for me:

// get radio buttons value
console.log( "radio1: " +  $('input[id=radio1]:checked', '#toggle-form').val() );
console.log( "radio2: " +  $('input[id=radio2]:checked', '#toggle-form').val() );

<script src=""></script>
<form id="toggle-form">
  <div id="radio">
    <input type="radio" id="radio1" name="radio" checked="checked" /><label for="radio1">Plot single</label>
    <input type="radio" id="radio2" name="radio"/><label for="radio2">Plot all</label>

This should work:


Note the "" usaged around the input:checked and not '' like the Peter J's solution

To get the value of the selected radioName item of a form with id myForm:

$('input[name=radioName]:checked', '#myForm').val()

Here's an example:

$('#myForm input').on('change', function() {
   alert($('input[name=radioName]:checked', '#myForm').val()); 
<script src=""></script>
<form id="myForm">
  <input type="radio" name="radioName" value="1" /> 1 <br />
  <input type="radio" name="radioName" value="2" /> 2 <br />
  <input type="radio" name="radioName" value="3" /> 3 <br />

To get the value of the selected radio that uses a class:


Use this..

$("#myform input[type='radio']:checked").val();

Use this:

value = $('input[name=button-name]:checked').val();

You can use the :checked selector along with the radio selector.


You need access with the :checked selector:

Check this doc:

a example:

$('input[name=radioName]:checked', '#myForm').val()
$('#myForm input').on('change', function() {
	$('#val').text($('input[name=radioName]:checked', '#myForm').val());
#val {
  color: #EB0054;
  font-size: 1.5em;
<script src=""></script>

<h3>Radio value: <span id='val'><span></h3>
<form id="myForm">
  <input type="radio" name="radioName" value="a"> a <br>
  <input type="radio" name="radioName" value="b"> b <br>
  <input type="radio" name="radioName" value="c"> c <br>

 $(".Stat").click(function () {
     var rdbVal1 = $("input[name$=S]:checked").val();
