I ve just have a similar problem  a simple solution is to just use    click     Any other solution will work if you refresh radio after calling function

Some times above solutions do not work  then you can try below   jQuery uniform update jQuery   yourElementID   attr  checked  true    jQuery uniform update jQuery   yourElementID   attr  checked  false      Another way you can try is   jQuery  input radio name yourElementName  nth 0    attr  checked  true

If property name does not work don t forget that id still exists  This answer is for people who wants to target the id here how you do      input id element id  value element value    prop  checked  true     Because property name does not work for me  Make sure you don t surround id and name with double single quotations   Cheers

Try this   To check Radio button using Value use this      input name type  value 2    attr  checked   true      Or     input name type  value 2    attr  checked    checked      Or     input name type  value 2    prop  checked    checked      To check Radio button using ID use this       radio 1   attr  checked   checked      Or      radio 1   prop  checked   checked

The   prop way is better     document  ready function                                          radio 1   prop  checked   true                 and you can test it like the following     document  ready function                                          radio 1   radio 2     radio 3   change function              if      radio 1   is   checked                      div1   show                      else if      radio 2   is   checked                      div2   show                      else                  div3   show

This answer is thanks to Paul LeBeau in a comment  I thought I d write it up as a proper answer since there surprisingly wasn t one  The only thing that worked for me  jQuery 1 12 4  Chrome 86  was     quot  js-my-radio-button quot   trigger  quot click quot     This does everything I want     changes which radio button looks selected  both visually and programmatically  and triggers events such as change on the radio button  Just setting the  quot checked quot  attribute as other answers suggest would not change which radio button was selected for me

For versions of jQuery equal or above      1 6  use       radio 1   prop  checked   true     For versions prior to   lt   1 6  use       radio 1   attr  checked    checked      Tip  You may also want to call click   or change   on the radio button afterwards  See comments for more info
