小编mar*_*are的帖子

这是我的自定义模型绑定器.我将断点设置为BindModel但不会被此控制器操作触发:

public ActionResult Create(TabGroup tabGroup)

...

public class BaseContentObjectCommonPropertiesBinder : DefaultModelBinder
{
    public new object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
    {
        if (controllerContext == null)
        {
            throw new ArgumentNullException("controllerContext");
        }
        if (bindingContext == null)
        {
            throw new ArgumentNullException("bindingContext");
        }

        BaseContentObject obj = (BaseContentObject)base.BindModel(controllerContext, bindingContext);
        obj.Modified = DateTime.Now;
        obj.Created = DateTime.Now;
        obj.ModifiedBy = obj.CreatedBy = controllerContext.HttpContext.User.Identity.Name;
        return obj;
    }

我的注册:

//尝试了这两行

ModelBinders.Binders[typeof(TabGroup)] = new BaseContentObjectCommonPropertiesBinder();
ModelBinders.Binders.Add(typeof(TabGroup), new BaseContentObjectCommonPropertiesBinder());

如何在Ninject中编写此StructureMap行

        ForRequestedType<HttpContextBase>()
            .TheDefault.Is.ConstructedBy(x => new HttpContextWrapper(HttpContext.Current));

？

此查询实际上有效但返回ClientName设置为nullFirstName或Lastname的新对象null(两者中的任何一个).我怎么能绕过那个？我想有一个空字符串而不是null那些行.

var clients =
                    from client in _repository.GetAll()
                    where (client.Firstname.StartsWith(query) || client.Lastname.StartsWith(query))
                    select new
                            {
                                ClientName = (client.Firstname + " " + client.Lastname).Trim(),
                                client.Firstname,
                                client.Lastname,
                                client.Address1,
                                client.Address2,
                                client.client_id,
                                client.PrettyId,
                                client.PostCode.postalcode,
                                client.PostCode.postname
                            };

我有以下代码将click事件功能连接到提交按钮.我知道event.target并且this并不总是相同(据我所知它取决于事件附加到哪里以及实际解雇了它)但在这种情况下事件被附加到按钮上,按钮也触发了它,所以它们应该是相同.还是我错了？

 modals.init = function () {
    // wire up submit() function to the submit button
    modals.config.$submitBtn.on('click', submit);
  };

  function submit(event) {
    event.preventDefault();
    var $this = $(this);
    alert(event.target.id); // fine
    alert($this.id); // undefined
}

在 CreateView() 方法（在下面检查我的视图引擎）或在我的自定义操作过滤器（也在下面）中，我必须以某种方式检查我们请求的视图是否是 ViewUserControl。因为否则我会收到一个错误说

“当视图是 ViewUserControl 时，不能指定主名称。”

当我在 QueryString 中有“modal=true”并且视图请求是 ViewUsercontrol 时，因为您无法在 ViewUserControls 上设置母版页（显然）。

这是我现在的自定义视图引擎代码：

    public class PendingViewEngine : VirtualPathProviderViewEngine
    {
        public PendingViewEngine()
        {
            // This is where we tell MVC where to look for our files. 
            /* {0} = view name or master page name       
             * {1} = controller name      */
            MasterLocationFormats = new[] {"~/Views/Shared/{0}.master", "~/Views/{0}.master"};
            ViewLocationFormats = new[]
                                    {
                                        "~/Views/{1}/{0}.aspx", "~/Views/Shared/{0}.aspx", "~/Views/Shared/{0}.ascx",
                                        "~/Views/{1}/{0}.ascx"
                                    };
            PartialViewLocationFormats = new[] {"~/Views/{1}/{0}.ascx", "~/Views/Shared/{0}.ascx"};
        }

        protected override IView CreatePartialView(ControllerContext controllerContext, string partialPath)
        { …

此代码导致第二行出错($('boxes div.box'))

<script type="text/javascript">

    $(document).ready(function () {
        boxes = $('#boxes div.box');
        images = $('#images > div');
        boxes.each(function (idx) {
            $(this).data('image', images.eq(idx));
        }).hover(
            function () {
                boxes.removeClass('active');
                images.removeClass('active');
                $(this).addClass('active');
                $(this).data('image').addClass('active');
            });
    });

</script>

错误是"对象不支持此属性或方法".同样的页面在Firefox和Chrome中运行良好.

任何人？
