问题 Visual Studio 2012 - ASP.net - MVC 4 I am having troubles displaying an image from a server path which is stored in a database. I am using HttpPostedFileBase to retrieve the file the user has uploaded: using (var uow = _db.CreateUnitOfWork()) { if (imageUpload != null && imageUpload.ContentLength > 0) { var fileName = Path.GetRandomFileName() + Path.GetExtension(imageUpload.FileName); var path = Path.Combine(System.Web.Hosting.HostingEnvironment.MapPath("~/Uploads"), fileName); imageUpload

问题 I have a method that looks like this function endcall_click(leadid) { document.location = '@Url.Action("index","dispo",new{id=leadid})/'; } Of course it doesn't work because it treats "leadid" as a server side variable but I want to inject the javascript variable passed into the method. I tried wrapping lead id in but that didn't work. function endcall_click(leadid) { document.location = '@Url.Action("index","dispo",new{id="<text>leadid</text>"})/'; } Any ideas? 回答1: You can't inject

问题 I have seen in another post that you can call a JavaScript function in your razor code like so: @:FunctionName() For me though this only outputs the actual words FunctionName() Here is my view: @model PriceCompare.Models.QuoteModel @{ ViewBag.Title = "Quote"; } <h2>Quote</h2> @if (@Model.clarify == true) { // do drop down loic @:ShowClarify(); } else { // fill quote @:ShowQuote(); } <div class="clarify"> You can see the clarify div </div> <div class="quote"> You can see the quote div </div>

问题 I'm trying to edit a list of items in a strongly-typed razor view. The templates don't give me the option to edit a list of objects in a single view so I merged the List view with the Edit view. I only need to edit one boolean field in a checkbox. The problem is that i cant get the data back to the controller. How do i do it? FormCollection ? Viewdata ? Thanks in advance. Here's the code: Models: public class Permissao { public int ID { get; set; } public TipoPermissao TipoP { get; set; }

问题 I recently installed vs 2013 professional and opened one of my side project applications in it . The project is an MVC3 application using the razor view engine. I noticed that when editing a view (cshtml ) I wasn't getting access to intellisense that I was used to in 2012. 2 Examples i noticed right away were @Url.Content() and @Viewbag. The code still compiles and runs, just no intellisense. After messing with it a bit i figured i should check the upgrade log and sure enough i found ...

问题 When I build my views, I'd like to eliminate as much processing logic as possible. Ideally, I'd like to stick to just HTML and rendering values with Razor. So suppose I have a FooModel with a list of BarModel objects: public class FooModel { public List<BarModel> Bars { get; set; } public string FoosFirstValue { get; set; } public string FoosOtherValue { get; set; } } public class BarModel { public string SomeValue { get; set; } public string SomeOtherValue { get; set; } } And in my view, I

问题 I am assembling a few lines in JavaScript using Razor. I thought the easiest way would be to assemble the entire JavaScript block first, then output the entire thing. The problem is, the single quotes are being rendered as & #39;. Is it possible to change the last line to get this to write correctly: var friendArray = new Array(); @{ int i = 0; string jsString=""; foreach(var friend in friends) { jsString = jsString + "friendArray["; jsString = jsString + i.ToString(); jsString = jsString + "
