  <script language="javascript" type="text/javascript">
$("#btnok").live("click", function () {
            var username = $("#name").val();
            var password = $("#password").val();
            var clientid = $("#clientid").val();
            $.ajax({
                type: 'POST',
                url: 'HostingService.asmx/SETusers',
                data: "{username:" + JSON.stringify(username) + ",password:" + JSON.stringify(password) + ",clientid:" + JSON.stringify(clientid) + "}",
