Retrieving selected string from a combobox

Question

Hi folks

 

I've written this little snippet to help simplify my question.  Basically, on the combobox change I'm displaying the value of the selection - so 21 if I select BMW.  How could I display BMW instead? 

<select id="myWeeCombo" onchange="myFunction()">

    <option value="11">Audi</option>

    <option value="21">BMW</option>

    <option value="31">Mercedes</option>

    <option value="41">Volvo</option>

</select>

<p id="demo"></p>

<script>

    function myFunction()

   {

        var x = document.getElementById("myWeeCombo").value;

        document.getElementById("demo").innerHTML = "You selected: " + x;

    }

</script>
