Hi,
I hav success create a html version.
<p>Select a new car from the list.</p>
<select id="mySelect" onChange="myFunction()">
<option value="Audi">Audi
<option value="BMW">BMW
<option value="Mercedes">Mercedes
<option value="Volvo">Volvo
</select>
<p>When you select a new car, a function is triggered which outputs the value of the selected car.</p>
<form name="form1" method="post" action="">
<label>aaa
<textarea name="textarea" id="textArea"></textarea>
</label>
</form>
<p id="demo"></p>
<script>
function myFunction() {
var x = document.getElementById("mySelect").value;
document.getElementById("demo").innerHTML = "You selected: " + x;
document.getElementById("textArea").value ="text " + x;
//$("textarea#ExampleMessage").val(result.exampleMes sage);
}
</script>
