This can be achieved by returning ContentResult MSDN

return Content("<script language='javascript' type='text/javascript'>alert('Hello world!');</script>");

or other way would be making use of ajax

return json(new {message="hello"});  

 $.ajax({
        url: URL,
        type: "POST",
        success: function(data){alert(data.message)},    
    });
