单击DIV时在单选数值之间切换

<div id="divContainer">
  <input type="radio" name="radioGroup" value="Option 1"> Option 1
  <br>
  <input type="radio" name="radioGroup" value="Option 2"> Option 2
  <br>
  <input type="radio" name="radioGroup" value="Option 3"> Option 3
</div>

var divContainer = document.getElementById("divContainer");
divContainer.addEventListener("click", toggleRadioValue);

function toggleRadioValue(event) {
  var target = event.target;
  if (target.tagName === "INPUT" && target.type === "radio") {
    var radioGroup = document.getElementsByName(target.name);
    for (var i = 0; i < radioGroup.length; i++) {
      if (radioGroup[i].value !== target.value) {
        radioGroup[i].checked = false;
      }
    }
  }
}
