asp.net-mvc – POST数据中不包含MVC 3远程验证表单按钮

我有一个ASP.NET MVC3应用程序,并在我的一个模型类上进行远程验证.我发现如果在提交表单之前打开该模型的编辑视图并且未调用远程验证例程(由于没有编辑带有远程验证的字段),则按钮单击以POST表单不包括在请求发送到Action方法的数据.

如果在表单发布之前调用远程验证例程 – 单击该按钮以提交POST中包含的表单IS.

我需要知道在服务器上调用Action时单击了哪个按钮,以便我可以确定用户是否单击了UPDATE或CANCEL.

如果我从模型中删除远程验证,则表单每次都会正确提交.

为什么在表单提交之前未调用远程验证时,用于提交表单的按钮将从表单发布中排除.

谢谢

以下是一些示例代码：

@model Channel
<script src="@Url.Content("~/Scripts/jquery-1.6.1.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>

@using (Html.BeginForm()) {
<fieldset>
    <legend>Edit Channel</legend>

    @Html.HiddenFor(model => model.ChannelGUID)


    <div class="editor-label">Name</div>
    <div class="editor-field">
        @Html.EditorFor(model => model.Name)
        @Html.ValidationMessageFor(model => model.Name)
    </div>

    <div class="editor-label">Description</div>
    <div class="editor-field">
        @Html.EditorFor(model => model.Description)
        @Html.ValidationMessageFor(model => model.Description)
    </div>

    <div class="editor-label">Channel Code</div>
    <div class="editor-field">
        @Html.EditorFor(model => model.Code)
        @Html.ValidationMessageFor(model => model.Code)
    </div>

    <p>
        <button type="submit" name="updateCommand" value="Update">Update</button>
        <button type="submit" class="cancel">Cancel</button>
    </p>
</fieldset>
}

这是行动

[HttpPost]
public ActionResult Edit(string updateCommand,Channel channel)
{
    if (updateCommand != null)
    {
     //update clicked
    }
    else
    {
     //cancel clicked
    }

这是模型属性Code的远程属性

[Remote("IsChannelCodeUnique","Channel",AdditionalFields = "ChannelGUID",ErrorMessage = "code must be unique")]

$('input[type="submit"]').click(function () {
    var hidden = $("<input type='hidden'/>").attr("name",this.name).val(this.value).appendTo($(this).closest("form"));
});
