单击单选按钮后如何清除文本输入？

document.getElementById("radioButton").addEventListener("click", function() {
  document.getElementById("textInput").value = "";
});

<form id="myForm">
  <input type="radio" name="myRadio" value="option1">
  <input type="radio" name="myRadio" value="option2">
  <input type="text" id="textInput">
</form>

<script>
  document.getElementById("myForm").addEventListener("click", function() {
    this.reset();
  });
</script>

<input type="radio" name="myRadio" value="option1" onclick="clearTextInput()">
<input type="radio" name="myRadio" value="option2">
<input type="text" id="textInput">

<script>
  function clearTextInput() {
    document.getElementById("textInput").value = "";
  }
</script>
