<form>
<fieldset>
<legend>Link-href</legend>
<label for="WeekSelect">Sales Target Week:
<input type="week" id="WeekSelect" value="2020-W13" disabled>
</label>
<input type="button" onclick="enableWeekInput()" value="Change Sales Target Week">
<input type="button" onclick="changeStyle()" value="Change Style">
<div id="divDisplay"></div>
</fieldset>
</form>
<script>
   var divDisplay = document.getElementById("divDisplay");
   var inputWeek = document.getElementById("WeekSelect");
   var extStyle = document.getElementById("extStyle");
   divDisplay.textContent = 'Week Input disabled: '+inputWeek.disabled;
   function enableWeekInput() {
      inputWeek.disabled = false;
      divDisplay.textContent = 'Week Input disabled: '+inputWeek.disabled;
