问题 I've just started using AntiXSS (4.3.0), mostly to use @Encoder.JavaScriptEncode as described here. I installed AntiXSS from Nuget, then added encoderType="Microsoft.Security.Application.AntiXssEncoder, AntiXssLibrary" to <httpRuntime in my Web.config. In my view, I have the following line (within <script> tags): var userId = @Encoder.JavaScriptEncode(User.Identity.GetUserId()); Which I would expect to output var userId = 'user-id'; but instead outputs: var userId = 'user-id'; I assume this

问题 With Automapper, is it possible to project a smaller object onto a larger one? For example, a controller accepts data as a ViewModel instance. I would then need to create a record in a database. So I would project this View Model onto a Domain Model. Once I have a Domain Model instance populated with View Model data I would then manually populate the additional fields in the Domain Model before storing data in the database. Is it possible to do so? Thanks. 回答1: Yes this is perfectly possible.

问题 I'm having difficulties to assign just a basic number from Model to a Javascript variable via Razor. All that I came up with was the code below, which works, but is rather ugly as I have to convert the string value into a number. Is there any other way to just get it right away in the numeric format without any conversions? var MyNumber = parseInt('@Model.MyNumber'); 回答1: You should be able to do this: var MyNumber = @Model.MyNumber; or better, use the brackets to make the Razor part explicit

问题 I have read a few pieces of conflicting information regarding MVC 4's out-of-the-box support for JSON.NET I gathered that MVC is serializing JSON by default using JSON.NET now, however I still have the tell-tale MS date format in my JSON output. Is there any bootstrapping that still needs to be done? Example action: // // GET: /Test/ [HttpGet] public JsonResult Test() { return Json(new {date = DateTime.Now}, JsonRequestBehavior.AllowGet); } results in: { "date": "/Date(1355399663508)/" } 回答1:
