C# - How To Send Text To An Aspcontrol Via Jquery

Is there a way to send data to an aspcontrol say a label called label1? Via jquery?

I know jquery only likes html but is there a way to just send the raw text to an asp control using a similar method below:

<script type="text/javascript">
$(function () {
$('button').click(function () {
$(document).ready(function () {
var x = $('textarea').val();
$('textarea').val('');
var label = $("#<%= Label1.ClientID %>");
var newdiv = $("<div></div>").html(x).attr('id', 'test');
$('#test1').append(newdiv);
var serializer = new XMLSerializer();
label.text(serializer.serializeToString(newdiv));
return false;
});
});
});
</script>
