Answer 1

Use onchange event to excecute function whenever the dropdown list clicked.

<select id="mylist" onchange = "go()">
<option value="value1">value1</option>
<option value="value2">value2</option>
</select>

<script>
  function go()
  {
    var x = document.getElementById("mylist").value;
    console.log(x);
  }
</script>
