ASP.net MVC application URL in JavaScript

Question

I have hosted an MVC application on my IIS under default website. So I can access the application by browsing to http://localhost/appname.

I also have a URL rewrite module which returns the same homepage if the URL entered is like this http://localhost/appname/request/*

I would like to get the path url (http://localhost/appname/)in my index.html file. I am using razor syntax. So in case I host the site under a different path or different appname, my ajax queries and css won't be affected.

How do I get the http://localhost/appname in index.html file's javascript.

You can't access the full application path (ie. www.hostname.com/appname/) in JavaScript as it has no knowledge of the server-side implementation, it's just a URL to JavaScript.

You could inject the app path into your page somewhere using @Url.Content("~/...").

<script type="text/javascript">
    var appPath = @Url.Content("~/");
</script>
<script type="text/javascript" src="@Url.Content("~/scripts/main.js")"></script>

In the above, main.js will be able to access the appPath variable.

I used that and I get appPath = http://hostname/appname/request/. Basically @Url.Content will give you whatever request server received from the client. It won't send you app path.

I will try to use RequestContext.ApplicationPath. And you are right, this is a server side implementation.

 var base = "@Request.Url.GetLeftPart(UriPartial.Authority)";
 var path = "@Request.ApplicationPath";
 var baseURL = base + path + "/";
