Can't get site root url in asp mvc

Question

I need to get site root url in razor page in javascript code:

...
var siteRootUrl = \'@Url.Content(\"~\")\';
...

But all I get from this is

Answer 1

@Url.Content() returns the root RELATIVE path, that is the path from the root of the domain.

So if your site was at www.foo.com/site then Url.Content() returns /site

Ishmael's response is correct. You will need to parse a full url.
