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">
$(document).ready(function ()
{
var label = $("#<%= testLabel.ClientID %>");
var div = $("<div></div>").html("content").attr('id', 'test');
var serializer = new XMLSerializer();

label.text(serializer.serializeToString(div));
});
</script>
