jSignature + asp.net Best Practice? about jsignature

[Gfweis]

I use webservices. Something like...

// Accept Signature /////////////////////////////////////////////////////////////////////////////////
var baseUrl = RootUrl + "WebServices/Pt.asmx/";

function SignatureAccept() {
var $cbs = $('input[name="ToDeliver"]'); // This is series of Checkboxes
var Keys = '';
$cbs.each(function () { if (this.checked) Keys += this.value + "~"; });
var Signature = $("#divSignature").jSignature("getData", "base30");
var Notes = $('#deliveryNotes').val();
var Confirm = ($("#deliveryConfirmation").val() === '1');
var jsonData = JSON.stringify({ "Token": Token, "SignatureType": Signature[0], "SignatureData": Signature[1], "Keys": Keys, "Notes": Notes, "Confirm": Confirm });
$.ajax({
url: baseUrl + "DeliverE",
data: jsonData,
success: function (data) {
if (data.d.Success) { // Variable passed back from webservice
$("#divShowPackages").hide(); // hide a few items
$("#divGetSignature").hide();
$("#divFindResident").show(); // screen that we want to show
$("#divSignature").replaceWith(divCloneSignature); // Copy of the div before drawing signature
Clear(); // Clears some of our variables
var Keys = '';
SoundComplete(); // Beeps on success
}
MessagesShow(data.d.Message); // Our message handler
}
});
}

Hope this helps.
