directly calling a radio button many times gives you the value of the FIRST button  not the CHECKED button   instead of looping thru radio buttons to see which one is checked  i prefer to call an onclick javascript function that sets a variable that can later be retrieved at will    lt input type  radio  onclick  handleClick this   name  reportContent  id  reportContent  value   reportFleet php   gt    which calls   var currentValue   0  function handleClick myRadio        currentValue   myRadio value      document getElementById  buttonSubmit   disabled   false       additional advantage being that i can treat data and or react to the checking of a button  in this case  enabling SUBMIT button

You can get the value by using the checked property   var rates   document getElementsByName  rate    var rate value  for var i   0  i  lt  rates length  i         if rates i  checked           rate value   rates i  value

You can also loop through the buttons with a forEach-loop on the elements      var elements   document getElementsByName  radioButton        var checkedButton      console log elements       elements forEach e   gt            if  e checked                  if radio button is checked  set sort style             checkedButton   e value

var rates   document getElementById  rates   value    The rates element is a div  so it won t have a value  This is probably where the undefined is coming from   The checked property will tell you whether the element is selected   if  document getElementById  r1   checked      rate value   document getElementById  r1   value

var rates   document getElementById  rates   value    cannot get values of a radio button like that instead use  rate value   document getElementById  r1   value

Assuming your form element is referred to by myForm variable below  and that your radio buttons share the name  my-radio-button-group-name   the following is pure JavaScript and standards compliant  although I have not checked it to be available everywhere    myForm elements namedItem  my-radio-button-group-name   value   The above will yield the value of a checked  or selected  as it is also called  radio button element  if any  or null otherwise  The crux of the solution is the namedItem function which works with radio buttons specifically   See HTMLFormElement elements  HTMLFormControlsCollection namedItem and especially RadioNodeList value  as namedItem usually returns a RadioNodeList object   I use MDN because it allows one to track standards compliance  at least to a large degree  and because it is easier to comprehend than many WhatWG and W3C publications

Another  apparently older  option is to use the format   document nameOfTheForm nameOfTheInput value   e g  document mainForm rads value    x000D   x000D  document mainForm onclick   function    x000D      var radVal   document mainForm rads value  x000D      result innerHTML    You selected    radVal  x000D    x000D   lt form id  mainForm  name  mainForm  gt  x000D       lt input type  radio  name  rads  value  1    gt  x000D       lt input type  radio  name  rads  value  2    gt  x000D       lt input type  radio  name  rads  value  3    gt  x000D       lt input type  radio  name  rads  value  4    gt  x000D   lt  form gt  x000D   lt span id  result  gt  lt  span gt  x000D   x000D   x000D    You can refer to the element by its name within a form  Your original HTML does not contain a form element though   Fiddle here  works in Chrome and Firefox   https   jsfiddle net Josh Shields 23kg3tf4 1

In Javascript we can get the values by using Id s  getElementById    in the above code you posted has contain name not Id  so you to modify like this  if  document getElementById  r1   checked      rate value   document getElementById  r1   value      use this rate value according to your code

If the buttons are in a form var myform   new FormData getformbywhatever   myform get  rate    QuerySelector above is a better solution  However  this method is easy to understand  especially if you don t have a clue about CSS  Plus  input fields are quite likely to be in a form anyway  Didn t check  there are other similar solutions  sorry for the repetition

For you people living on the edge   There is now something called a RadioNodeList and accessing it s value property will return the value of the currently checked input  This will remove the necessity of first filtering out the  checked  input as we see in many of the posted answers    Example Form   lt form id  test  gt   lt label gt  lt input type  radio  name  test  value  A  gt  A lt  label gt   lt label gt  lt input type  radio  name  test  value  B  checked gt  B lt  label gt   lt label gt  lt input type  radio  name  test  value  C  gt  C lt  label gt   lt  form gt    To retrieve the checked value  you could do something like this   var form   document getElementById  test    alert form elements  test   value     The JSFiddle to prove it  http   jsfiddle net vjop5xtq   Please note this was implemented in Firefox 33  All other major browser seems to support it   Older browsers will require a polfyill for RadioNodeList for this to properly function

A year or so has passed since the question was asked  but I thought a substantial improvement of the answers was possible  I find this the easiest and most versatile script  because it checks whether a button has been checked  and if so  what its value is     lt  DOCTYPE html gt   lt html gt   lt head gt       lt meta charset  utf-8  gt       lt title gt Check radio checked and its value lt  title gt   lt  head gt   lt body gt        lt form name  theFormName  gt           lt input type  radio  name  theRadioGroupName  value  10  gt           lt input type  radio  name  theRadioGroupName  value  20  gt           lt input type  radio  name  theRadioGroupName  value  30  gt           lt input type  radio  name  theRadioGroupName  value  40  gt           lt input type  button  value  Check  onclick  getRadioValue  theRadioGroupName    gt       lt  form gt        lt script gt          function getRadioValue groupName                var radios   theFormName elements groupName               window rdValue     declares the global variable  rdValue              for  var i 0  i lt radios length  i                      var someRadio   radios i                   if  someRadio checked                        rdValue   someRadio value                      break                                    else rdValue    noRadioChecked                             if  rdValue     10                     alert  10       or  console log  10                             else if  rdValue     noRadioChecked                     alert  no radio checked                                 lt  script gt   lt  body gt   lt  html gt    You can also call the function within another function  like this    function doSomething         getRadioValue  theRadioGroupName        if  rdValue     10                do something           else if  rdValue     noRadioChecked                do something else

My take on this problem with pure javascript is to find the checked node  find its value and pop it out from the array   var Anodes   document getElementsByName  A        AValue   Array from Anodes          filter node   gt  node checked          map node   gt  node value          pop    console log AValue     Note that I m using arrow functions  See this fiddle for a working example
