This solution does not require jQuery  const RADIO NAME    quot radioName quot   const radios   Array from document getElementsByName RADIO NAME    const checkedRadio   radios filter e  gt e checked    This uses jQuery  const radios   Array from     name   RADIO NAME      const checkedRadio   radios filter e  gt e checked    jQuery adds an extra layer of abstraction that isn t needed here  You could also use  const radios   Array from document querySelectorAll   name   RADIO NAME      const checkedRadio   radios filter e  gt e checked  0    But getElementsByName is simple and clear enough

Along with the CSS selector  checked  you can also use the prop function  as of jQuery 1 6   I can t remember what project I was working on where simply using     something   is   checked   only worked sometimes  and I resorted to also using     something   prop  checked   worked when it failed  but it led me to using both   In my code snippet below  I ve written two helper functions  is checked and get group value  The function is checked returns a boolean true false value  true if the input passed in the parameter is checked  also checks with the prop   function  or false if it s not checked  The function get group value takes the name of the radio inputs and returns the value of the one that is checked  or an empty string if none are checked  These helper functions will also work with checkboxes  not just radio buttons   Since the question did not define when they re retrieving the value s   I ve written a few listeners for four  3  different scenarios  when interacting with any radio button  when submitting the form  and when clicking one of these hard-coded buttons to do a one-time retrieval of the value of the group   Please note that I m using  click  to identify when the user interacts with the radio input element because  change  will never get triggered since the  value  attribute doesn t get changed when it s checked or not  I use this for checkboxes as well as radio buttons    x000D   x000D  function is checked input    x000D    var  input     input   x000D    return  input is   checked       input prop  checked      Returns a boolean value  True if checked  false if not  x000D    x000D  function get group value group name    x000D    var  inputs       name      group name       checked    x000D    if   inputs length    return  inputs first   val        If it exists  return the value of the first one found x000D    return       If it doesn t exist  return nothing x000D    x000D     form   on  submit   function e    x000D    e preventDefault    x000D    var  form     this   results       x000D     form find  input type radio    each function     x000D      var  input     this   x000D      if  is checked this     x000D        results  input attr  name       input val    x000D        x000D        x000D    console info  Form Results   results   x000D      x000D     form input type radio    on  click   function e    x000D    var group name     this  attr  name    x000D    console info  Radio Button Click   group name  get group value group name    x000D      x000D     button radio-button   on  click   function e    x000D    var group name     this  attr  id    x000D    console info  Button Click   group name  get group value group name    x000D      x000D   my-test   x000D    background   ffffff  x000D    color   000000  x000D    padding  16px  x000D    x000D   x000D  form   x000D    padding  8px  x000D    border  1px solid  999999  x000D    x000D   x000D  fieldset   x000D    border  none  x000D    x000D   lt script src  https   cdnjs cloudflare com ajax libs jquery 3 3 1 jquery min js  gt  lt  script gt  x000D   lt div class  my-test  gt  x000D     lt form gt  x000D      Group 1 x000D       lt fieldset gt  x000D         lt label gt  lt input type  radio  name  example-1  value  Foo  required   gt Foo lt  label gt  x000D         lt label gt  lt input type  radio  name  example-1  value  Bar  required   gt Bar lt  label gt  x000D       lt  fieldset gt  x000D      Group 2 x000D       lt fieldset gt  x000D         lt label gt  lt input type  radio  name  example-2  value  Banana  required   gt Banana lt  label gt  x000D         lt label gt  lt input type  radio  name  example-2  value  Apple  required   gt Apple lt  label gt  x000D       lt  fieldset gt  x000D       lt button type  submit  gt Submit lt  button gt  x000D     lt  form gt  x000D     lt p gt Press this button to just get the value of the first group   lt button class  radio-button  id  example-1  gt Foo or Bar  lt  button gt  lt  p gt  x000D     lt p gt Press this button to just get the value of the second group   lt button class  radio-button  id  example-2  gt Banana or Apple  lt  button gt  lt  p gt  x000D   lt  div gt  x000D   x000D   x000D

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

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   TL DR     label   click function       var selected             this  attr  for    val                  x000D   x000D    function     x000D       this outright does not work properly as explained above x000D        reported label   click function     x000D      var query      input name  filter   checked   val    x000D      var time    new Date    toString    x000D   x000D          query data-method  click event     html query     at     time   x000D        x000D   x000D       this works  but fails to update when same label is clicked consecutively x000D        reported input name  filter     on  change   function     x000D      var query      input name  filter   checked   val    x000D      var time    new Date    toString    x000D   x000D          query data-method  change event     html query     at     time   x000D        x000D   x000D       here is the solution I came up with x000D        reported label   click function     x000D      var query             this  attr  for    val    x000D      var time    new Date    toString    x000D   x000D          query data-method  click event with this     html query     at     time   x000D        x000D      x000D  input name  filter     x000D    display  none  x000D    x000D   reported label   x000D    background-color   ccc  x000D    padding  5px  x000D    margin  5px  x000D    border-radius  5px  x000D    cursor  pointer  x000D    x000D   query   x000D    padding  5px  x000D    margin  5px  x000D    x000D   query before   x000D    content   on   attr data-method       x000D    x000D   data-method  click event     x000D    color  red  x000D    x000D   data-method  change event     x000D    color   cc0  x000D    x000D   data-method  click event with this     x000D    color  green  x000D    x000D   lt script src  https   ajax googleapis com ajax libs jquery 2 1 1 jquery min js  gt  lt  script gt  x000D   lt form id  reported  gt  x000D     lt input type  radio  name  filter  id  question  value  questions  checked  checked  gt  x000D     lt label for  question  gt Questions lt  label gt  x000D   x000D     lt input type  radio  name  filter  id  answer  value  answers  gt  x000D     lt label for  answer  gt Answers lt  label gt  x000D   x000D     lt input type  radio  name  filter  id  comment  value  comments  gt  x000D     lt label for  comment  gt Comments lt  label gt  x000D   x000D     lt input type  radio  name  filter  id  user  value  users  gt  x000D     lt label for  user  gt Users lt  label gt  x000D   x000D     lt input type  radio  name  filter  id  company  value  companies  gt  x000D     lt label for  company  gt Companies lt  label gt  x000D   x000D     lt div class  query  data-method  click event  gt  lt  div gt  x000D     lt div class  query  data-method  change event  gt  lt  div gt  x000D     lt div class  query  data-method  click event with this  gt  lt  div gt  x000D   lt  form gt  x000D   x000D   x000D

Try  myForm myOption value    x000D   x000D  function check     x000D    console log  myForm myOption value    x000D    x000D   lt form id  myForm  gt  x000D     lt input type  radio  name  myOption  value  1  gt  1  lt br gt  x000D     lt input type  radio  name  myOption  value  2  gt  2  lt br gt  x000D     lt input type  radio  name  myOption  value  3  gt  3  lt br gt  x000D   lt  form gt  x000D   lt button onclick  check    gt check lt  button gt  x000D   x000D   x000D

Here s how I would write the form and handle the getting of the checked radio   Using a form called myForm    lt form id  myForm  gt       lt input type  radio  name  radio1  class  radio1  value  val1    gt       lt input type  radio  name  radio1  class  radio1  value  val2    gt           lt  form gt    Get the value from the form       myForm  radio1 checked   val      If you re not posting the form  I would simplify it further by using    lt input type  radio  class  radio1  value  val1    gt   lt input type  radio  class  radio1  value  val2    gt    Then getting the checked value becomes           radio1 checked   val      Having a class name on the input allows me to easily style the inputs
