Pass Control To A JQuery Ajax Call?

I have the following jQuery event that gets fired every time an anchor is clicked. How can I pass a asp.net control (lets say a panel called "pnl_info") as one of the parameters, in addition to the "target" parameter i'm already passing?

<script type="text/javascript">
$(document).ready(function() {
$("a").click(function(event) {
$.ajax({
type: "POST",
url: "Default.aspx/Click",
data: "{target:'" + event.target + "'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
error: function(xhr, ajaxOptions, thrownError) {
alert(xhr.responseText);
$("#myContent").html(xhr.statusText);
//alert(xhr.responseText);
},
success: function(msg) {
alert(msg.d);
}
});
return false;
})
})
</script>
