How to clear input field after radio button click?

Question

After clicking "Select number of tweets from date", the "Select end date" input field must be removed. Can anyone help me? This is the code:

function yesnoCheck() {
  if (document.getElementById('yesCheck').checked) {
    document.getElementById('ifYes').style.display = 'block';
  } else document.getElementById('ifYes').style.display = 'none';

}

<form>
  <input type="radio" onclick="javascript:yesnoCheck();" name="yesno" id="noCheck">Select date range <br>
  <br>
  <input type="radio" onclick="javascript:yesnoCheck();" name="yesno" id="yesCheck">Select number of tweets from date<br><br>
  <div id="ifYes" style="display:none">
    Desired number of tweets <input type="number" min="1" max="20" id='yes' name='yes'><br>
  </div>


  <br>
  <img src="icon2.png"><label for="date">Select start date:</label><br>
  <input type="datetime-local" id="Test_DatetimeLocal"><br><br>
  <img src="icon2.png"><label for="date">Select end date:</label><br>
  <input type="datetime-local" id="Test_DatetimeLocal"><br><br>
  <input type="submit" value="submit" class="submit">
</form>

Follow your #ifYes tags. Wrap the input and label with div, assign it an id, and then just use document.getElementById('select-end-period').style.display = 'none';

function yesnoCheck() {
  if (document.getElementById('yesCheck').checked) {
    document.getElementById('ifYes').style.display = 'block';
    document.getElementById('select-end-period').style.display = 'none';

  } else {
    document.getElementById('ifYes').style.display = 'none';
    document.getElementById('select-end-period').style.display = 'block';
  }
}

<form>
  <input type="radio" onclick="javascript:yesnoCheck();" name="yesno" id="noCheck">选择期间 <br>
  <br>
  <input type="radio" onclick="javascript:yesnoCheck();" name="yesno" id="yesCheck">从日期开始的推文数量<br><br>
  <div id="ifYes" style="display:none">
    期望推文数量 <input type="number" min="1" max="20" id='yes' name='yes'><br>
  </div>


  <br>
  <img src="icon2.png"><label for="date">选择开始日期:</label><br>
  <input type="datetime-local" id="Test_DatetimeLocal"><br><br>
  <div id="select-end-period">
    <img src="icon2.png"><label for="date">选择结束日期:</label><br>
    <input type="datetime-local" id="Test_DatetimeLocal"><br><br>
  </div>
  <input type="submit" value="提交" class="submit">
</form>
