There's two parts in this answer :

First if you want to update a part of your page with change event on the select

functionmyUpdateFunc()
{
  
  
  var mySelected = $("#CPU").find("option:selected").val();
  $('#divResults').html ('selected value :' + mySelected)
}

<scriptsrc="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script><formid="parts"><fieldset><legend>Choose your parts</legend>
            Any parts marked with * are required<br/><br/><labelfor="CPU">CPU*</label><br/><selectid="CPU"name="CPU"onchange="myUpdateFunc()"><optionvalue=""disabledselected>Select your Part</option><optionvalue="1">value 1</option><optionvalue="2">value 2</option></select><br/><divid="divResults"/><br/><br/>
