Checking Value of Radio Button Group via JavaScript?

Question

This may seem silly and downright stupid but I can\'t seem to figure out how to check the value of a radio button group in my HTML form via JavaScript. I have the following

Answer 1

function myFunction() {
document.getElementById("text").value='male'
 document.getElementById("myCheck_2").checked = false;
  var checkBox = document.getElementById("myCheck");
  var text = document.getElementById("text");
  if (checkBox.checked == true){
    text.style.display = "block";
  } else {
     text.style.display = "none";
  }
}
function myFunction_2() {
document.getElementById("text").value='female'
 document.getElementById("myCheck").checked = false;
  var checkBox = document.getElementById("myCheck_2");
  var text = document.getElementById("text");
  if (checkBox.checked == true){
    text.style.display = "block";
  } else {
     text.style.display = "none";
  }
}

Male: 
Female:
