How can I create a relative Url in a html link element for a web app running on IIS?

Let say I have 开发者_高级运维a web application :

www.mymvcsite.com/MyVirtualDirectory/Controller/Action

In my view I have a <a href="/FolderA/myfile.pdf">. Problem is the entire Html is coming from from a database! Aha! You thought this was as easy as @Url.Content()... well that doesn't work cause the html is dynamic in fact I have no idea that there is even link element in the markup I'm blindly outputting it to the view.

So what do I need to put in the href in order for it to resolve the Url properly.

Ie. "myfile.pdf" is located at...

www.mymvcsite.com/MyVirtualDirectory/FolderA/myfile.pdf

BUT for some reason in the browser the url ends up being

"www.mymvcsite.com/FolderA/myfile.pdf"

Note that the "MyVirtualDirectory" is missing! I even tried adding a "~" to the Url but that doesn't work either.

Thanks!

You need to store the relative url in a hidden field:

<input id='hidPartialUrl' type='hidden' value='<%:ResolveUrl("~/") %>'/>

All links should be relative to the root of the site and have a common class name:

<a href='/FolderA/myfile.pdf' class='fixThisLink'>PDF</a> 

Then when you load it into the page you do:

var hiddenHref = document.getElementById('hidPartialUrl').href;
var links = document.getElementsByClassName('fixThisLink'); 
for(var i = 0; i < links.length; i++) {
    links[i].href = hiddenHref + links[i].href;
}

Set the href property on each one returned to include the first part of your url. I would store the first part of your url in a hidden field.
