我已经从他的博客更新了Steves koListEditor的礼品模型,包括一个修改的DateTime字段：

public class GiftModel
{
    public string Title { get; set; }
    public double Price { get; set; }
    public DateTime Modified { get; set; }
}

然后我更新了Index.aspx以包含新的字段：

<asp:Content ContentPlaceHolderID="MainContent" runat="server">
    <h1>Gift list editor</h1>

    <p>You have asked for <span data-bind="text: gifts().length">&nbsp;</span> gift(s)</p>

    <form class="giftListEditor">
        <table> 
            <tbody data-bind="template: { name: 'giftRowTemplate',foreach: gifts }"></tbody> 
        </table>

        <button data-bind="click: addGift">Add Gift</button>
        <button data-bind="enable: gifts().length > 0" type="submit">Submit</button>
    </form>

    <script type="text/html" id="giftRowTemplate"> 
        <tr> 
            <td>Gift name: <input class="required" data-bind="value: Title,uniqueName: true"/></td> 
            <td>Price: \$<input class="required number" data-bind="value: Price,uniqueName: true"/></td> 
            <td>Modified:  <input class="required date" data-bind="value: Modified,uniqueName: true"/></td> 
            <td><a href="#" data-bind="click: function() { viewmodel.removeGift($data) }">Delete</a></td> 
        </tr>
    </script>

    <script type="text/javascript">
        var initialData = <%= new JavaScriptSerializer().Serialize(Model) %>;
        var viewmodel = { 
            gifts : ko.observableArray(initialData),addGift: function () { 
                this.gifts.push({ Title: "",Price: "",Modified:"" }); 
            },removeGift: function (gift) { 
                this.gifts.remove(gift); 
            },save: function() { 
                ko.utils.postJson(location.href,{ gifts: this.gifts }); 
            } 
        }; 

        ko.applyBindings(document.body,viewmodel);
        $("form").validate({ submitHandler: function() { viewmodel.save() } });
    </script> </asp:Content>

但是当JavaScriptSerializer序列化模型时

var initialData = <%= new JavaScriptSerializer().Serialize(Model) %>;

修改日期如下：

当使用英国日期I.e 25/01/2011 JavaScriptSerializer.Deserialize抛出以下异常：

25/01/2011 is not a valid value for
DateTime.

虽然我有两个问题在这里主要的问题是有人成功地从MVC 2使用knockout,并得到JavaScriptSerializer与DateTimes工作？我知道我可以编写自己的JavaScriptSerializer,但我希望有一个现成的解决方案在那里:)

以下是Steve Sanderson的koListEditor更新版本的代码：
