Open a view in an html file with url parameters

I am trying to create an MVC web app, without any MVC framework. What I've done is to make an index.html with a section were all the views are loaded, when a user wants them. This though creates the problem that when a user types a direct url like: www.foo.com/bar - it doesn't point him to the view bar. I know how to point the user to a webpage with a router file, but I don't know how to do it, when the view is only a part of a page and it is opened in another page. Can I do this with the router, or how can this be done?

For clarity I am running php on the server side and I use AJAX calls to get the views.
