.net – Using scripts in a master page with ASP.NET MVC

asp.netasp.net-mvcnetscripting

I'm fairly new to ASP.NET MVC, and I'm having a little trouble with scripts… in particular, I want to use jQuery in most pages, so it makes sense to put it in the master page. However, if I do (from my ~/Views/Shared/Site.Master):

<script src="../../Scripts/jquery-1.2.6.js" type="text/javascript"></script>

Then that is literally what goes down to the client – which of course only works if our current route happens to have the right number of levels. Starting with ~/Scripts/... doesn't work. Starting with /Scripts/... would only work if the project was at the site root (which I don't want to assume).

I have one working approach (I'll post below) – but: am I missing something?

I'd rather not have to involve a script-manager, as that seems to defeat the simplicity of the ASP.NET MVC model… or am I worrying too much?

Here's the way I can get it working, which works also for non-trivial virtuals – but it seems over-complicated:

<script src="<%=Url.Content("~/Scripts/jquery-1.2.6.js")%>" type="text/javascript"></script>

Best Answer

I have a AppHelper class with some methods for adding script references:

public static string ReferenceScript(string scriptFile)
{
    var filePath = VirtualPathUtility.ToAbsolute("~/Scripts/" + scriptFile);
    return "<script type=\"text/javascript\" src=\"" + filePath + "\"></script>";
}

so in your master page you can use:

<%= AppHelper.ReferenceScript("jquery-1.2.6.js") %>

Asp.net-mvc – Can an ASP.NET MVC controller return an Image

Use the base controllers File method.

public ActionResult Image(string id)
{
    var dir = Server.MapPath("/Images");
    var path = Path.Combine(dir, id + ".jpg"); //validate the path for security or use other means to generate the path.
    return base.File(path, "image/jpeg");
}

As a note, this seems to be fairly efficient. I did a test where I requested the image through the controller (http://localhost/MyController/Image/MyImage) and through the direct URL (http://localhost/Images/MyImage.jpg) and the results were:

MVC: 7.6 milliseconds per photo
Direct: 6.7 milliseconds per photo

Note: this is the average time of a request. The average was calculated by making thousands of requests on the local machine, so the totals should not include network latency or bandwidth issues.

Asp.net-mvc – Compile Views in ASP.NET MVC

From the readme word doc for RC1 (not indexed by google)

ASP.NET Compiler Post-Build Step

Currently, errors within a view file are not detected until run time. To let you detect these errors at compile time, ASP.NET MVC projects now include an MvcBuildViews property, which is disabled by default. To enable this property, open the project file and set the MvcBuildViews property to true, as shown in the following example:

<Project ToolsVersion="3.5" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
    <MvcBuildViews>true</MvcBuildViews>
  </PropertyGroup>

Note Enabling this feature adds some overhead to the build time.

You can update projects that were created with previous releases of MVC to include build-time validation of views by performing the following steps:

Open the project file in a text editor.
Add the following element under the top-most <PropertyGroup> element: <MvcBuildViews>true</MvcBuildViews>
At the end of the project file, uncomment the <Target Name="AfterBuild"> element and modify it to match the following:

<Target Name="AfterBuild" Condition="'$(MvcBuildViews)'=='true'">
    <AspNetCompiler VirtualPath="temp" PhysicalPath="$(ProjectDir)\..\$(ProjectName)" />
</Target>
