Everything functions correctly except:

JavaScript

$orders.append(newOrder.d);

It is supposed to add the

HTML

<li>name: somename, drink: somedrink</li>

to the

HTML

<ul class="orders">

in Default.aspx

Default.aspx

JavaScript

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
    <script type="text/javascript">
        $(function () {
            var $orders = $('.orders');
            var $name0 = $('#<%= name1.ClientID %>');
            var $drink0 = $('#<%= drink1.ClientID %>');

            $('#<%= add_order.ClientID %>').on('click', function () {
                var order = {
                    name: $name0.val(),
                    drink: $drink0.val()
                };
                $.ajax({
                    type: 'POST',
                    url: 'Myorder.aspx/ordered',
                    data: JSON.stringify(order),
                    contentType: "application/json; charset=utf-8",
                    dataType: "json",
                    success: function (newOrder) {
                        $orders.append(newOrder.d);
                    },
                    error: function () {
                        alert('Error in new order');
                    }
                });
            });
        });

Default.aspx.cs

C#

[System.Web.Services.WebMethod]
public static string ordered(string name,string drink)
{
    string data= "<li>name: " + name + ", drink: " + drink + "</li>";

    return data;
}

what it the value you get as "newOrder.d"?

Teledextri 3-Dec-14 5:05am

<li>name: somename, drink: somedrink</li>

Your code seems all right, so I suggest to debug what newOrder.d is!!! Check it!

I don't know why you made call just to prepare the <li> when you already have name and drink values available.

Sinisa Hajnal 3-Dec-14 6:27am

You already have all the values, save yourself server round trip and do it in javascript!

Remove your ajax call first and simply place the html inside orders like

C#

 $(function () {
            var name = $('#<%= name1.ClientID %>').val();
            var drink = $('#<%= drink1.ClientID %>').val();
 
            $('#<%= add_order.ClientID %>').on('click', function () {
             var items="<li>name: " + name+ ", drink: " + drink+ "</li>";
                 $('.orders').html(items);
//if you want to append : $('.orders').append(items);
            });
        });

Hope this helps

This flashes the order at button click but it does not save in the html ul the li.

Jameel VM 3-Dec-14 7:43am

save means? r u save this html inside the service?

Teledextri 3-Dec-14 7:45am

Yes save this into html
