How to make a radio button unchecked by clicking it

Question

Unlike check boxes  it is impossible for the user to deselect radio buttons once they are clicked   Is there any way so that they can be toggled programmatically using Javascript   This would be preferably without using jQuery

User · Answer

Most of the modern day browsers consider checked="anything" as checked="true".

You might have to remove the checked attribute if that makes sense in your case, one of which might be related to when you load the page.

$(this).removeAttr('checked')

This might help you in cases when you want your radio button to be checked adhering to some condition. You can simply remove the attribute to achieve that.

PS: Not helpful in all the cases.

This is my answer  though I made it with jQuery but only for the purpose of selecting elements and to add and remove a class  so you can easily replace it with pure JS selectors  amp  pure JS add attribute    lt input type  radio  name  radioBtn  gt   lt input type  radio  name  radioBtn  gt   lt input type  radio  name  radioBtn  gt     document  on  quot click quot    quot input name  radioBtn   quot   function        thisRadio     this       if  thisRadio hasClass  quot imChecked quot              thisRadio removeClass  quot imChecked quot            thisRadio prop  checked   false         else            thisRadio prop  checked   true           thisRadio addClass  quot imChecked quot

You could use the checked property of a radio button to uncheck it   Something like this    lt script gt   function uncheck        document getElementById  myRadio   checked   false              function check        document getElementById  myRadio   checked   true              lt  script gt   lt input id  myRadio  type  radio  checked  checked   gt   lt button onclick  uncheck     gt Uncheck lt  button gt   lt button onclick  check     gt Check lt  button gt     See it in action here  http   jsfiddle net wgYNa

Radio buttons are meant to be used in groups  as defined by their sharing the same name attribute  Then clicking on one of them deselects the currently selected one  To allow the user to cancel a    real    selection he has made  you can include a radio button that corresponds to a null choice  like    Do not know    or    No answer      If you want a single button that can be checked or unchecked  use a checkbox   It is possible  but normally not relevant  to uncheck a radio button in JavaScript  simply by setting its checked property to false  e g    lt input type radio name foo id foo value var gt   lt input type button value  Uncheck  onclick   document getElementById  foo   checked   false  gt

I came here because I had the same issue  I wanted to present the options to the user while leaving the option of remaining empty  Although this is possible to explicitly code using checkboxes that would complicate the back end   Having the user Control click is almost as good as having them uncheck it through the console  Catching the mousedown is to early and onclick is too late   Well  at last here is a solution  Just put these few lines once on the page and you have it made for all radio buttons on the page  You can even fiddle with the selector to customize it    x000D   x000D  window onload   function     x000D    document querySelectorAll  INPUT type  radio     forEach function rd    x000D      rd addEventListener  mousedown   function     x000D        if this checked    x000D          this onclick function     x000D            this checked false x000D            x000D          else   x000D          this onclick null x000D          x000D         x000D       x000D    x000D   lt input type radio name unchecksample gt  Number One lt br gt  x000D   lt input type radio name unchecksample gt  Number Two lt br gt  x000D   lt input type radio name unchecksample gt  Number Three lt br gt  x000D   lt input type radio name unchecksample gt  Number Four lt br gt  x000D   lt input type radio name unchecksample gt  Number Five lt br gt  x000D   x000D   x000D

As radio button mostly used in group  its a lot easier to grab them by getElementsByName         in your script tag   This will return an array  put an event listener on each array child and set the check state  Look at this sample    var myRadios   document getElementsByName  subscribe    var setCheck  var x   0  for x   0  x  lt  myRadios length  x          myRadios x  onclick   function            if setCheck    this                setCheck   this           else              this checked   false              setCheck   null                    This guide explain how the code works with a visual demonstration

Here s an example of where it is arguably appropriate to uncheck radio buttons other than by making a new selection  I have a dictionary whose entries can be selected using a variety of indices  Which index to use is selected by means of a set of radio buttons  However  there is also a  random entry  button that the user can use if he or she just wants to browse  Leaving an index in place when the entry has been selected by means of the random entry button would be misleading  so when this button is pressed  I uncheck all of the index selection radio buttons and replace the contents of the index frame with an empty page

How unchecking radio does  not  work You cannot easily implement uncheck trivially via if this checked  this checked   false   if you really want to  see the hacker way at the end  because the events fire in this order   mousedown or keydown mouseup or keyup if not checked  set the checked property now click input  only if state is changed  change  only if state is changed   Now in which event to perform the mentioned uncheck   mouseup or mousedown  then the step 3 the value is set back to true and change and input event doesn t even fire as the state didn t change when they are called in the sequence - so you can t uncheck it here click  then the state is always false and input and change also doesn t fire - so you can t check it input or change  it doesn t fire when the state is not changed and clicking selected element doesn t change the state - so you can t do anything useful here  The naive way As you can learn from the sequence above  the way is   read the previous state in mouseup set the state in click as negation of previous state  If you want to store the previous state in data attribute  keep in mind that it is saved as string  whereas the checked attribute is boolean  So you can implement it like  radio onmouseup   function     this dataset checked   this checked  1    quot  quot     radio onclick   function     this checked    this dataset checked     It seemingly works  but you should not do this for these reasons   the user may mousedown somewhere else  then hover above radio button  then mouseup  in this case mouseup fires and click does not the user may use Tab to focus radio group  then arrows to change  mouseup doesn t fire and click does  The proper way There is another issue  dynamically added radio buttons  There are two ways   element appendChild radio  - if you enable deselect on all radios in DOMContentLoaded event  this dynamically added radio is not affected element innerHTML     lt input type  quot radio quot  gt   - effectively replaces the HTML contents of the element and re-creates DOM inside it - so all event listeners are discarded  To solve  2   I recommend onclick content attribute  Note that element onclick   fn and element setAttribute  quot onclick quot    quot fn   quot   are two different things  Also note that onclick fires everytime the user activates the radio  regardless of the interface he used  Yet another issue  if you enable deselect  then you should also enable switching by Space to mimic checkboxes behaviour  The following code solves all mentioned issues   x000D   x000D  function deselectableRadios rootElement      if  rootElement  rootElement   document    if  window radioChecked  window radioChecked   null    window radioClick   function e        const obj   e target      if e keyCode  return obj checked   e keyCode  32      obj checked   window radioChecked    obj      window radioChecked   obj checked   obj   null        rootElement querySelectorAll  input type  radio     forEach  radio   gt        radio setAttribute  onclick    radioClick event         radio setAttribute  onkeyup    radioClick event              deselectableRadios    x000D   lt label gt  lt input type  radio  name  tag1  gt one lt  label gt   lt label gt  lt input type  radio  name  tag1  gt two lt  label gt   lt label gt  lt input type  radio  name  tag1  gt three lt  label gt   lt label gt  lt input type  radio  name  tag1  gt four lt  label gt  x000D   x000D   x000D   Now you can call deselectableRadios   anytime you dynamically add content and calling it on radios multiple times doesn t break it  You can also specify the rootElement to update only a subtree of HTML DOM and make your web faster  If you don t like the global state  you can use the hacker way  The hacker way The point is to abuse setTimeout on mouseup to call it after the checked property is set  function deselectable       setTimeout checked   gt  this checked    checked  0  this checked      Now you can make any radio button deselectable  radio onmouseup   deselectable   But this simple one-liner works just with clicking and doesn t solve the issues mentioned above  The modern way Deselectable radio is basically checkbox where only one in the group can be checked  If your browser supports the appearance CSS4 feature  you can simply  lt input type  quot checkbox quot  name  quot foo quot  style  quot appearance  radio quot  gt   and then in onclick event getElementsByName  quot foo quot   and uncheck all remaining checkboxes of the name  checkboxes doesn t send value if they are not checked
