Hi please help me with below question

I’m working on jsp, I have situation like in that jsp we are using spring form tags, my task is to create two radio buttons when user click on radio buttons I need to display different options and I need to send user opted radio button value to my controller.

<form:radiobutton path="test"> (for example) will set the name of the generated input element to "test". You can thus use document.querySelectorAll to select all the radio buttons with the same name. Then, loop over them and use addEventListener on each one.

for(const radio of document.querySelectorAll('input[type=radio][name="test"]')){
    radio.addEventListener("change", function(e){
      // do something on change
    });
}
