</form>
<button onclick="fillForm()">自动填充表单</button>

function fillForm() {
  var form = document.getElementById("myForm");
  var gender = form.elements["gender"].value;

  // 根据选中的值填充其他字段
  if (gender === "male") {
    form.elements["name"].value = "John Doe";
    form.elements["age"].value = "30";
  } else if (gender === "female") {
    form.elements["name"].value = "Jane Smith";
    form.elements["age"].value = "25";
  }
}
