How do I remove a Link in dom selector in following script

Question

I am using the following code to avoid refresh of links, but I have few links using Omniauth like facebook login, google login and twitter login, so I don't want to use this script for those links. How can I remove those links from this script. It is ruby on rails app.

   $(function(){
        var newHash      = '',
            $mainContent = $("#main-content");
        $(".nav").delegate("a","click",function(){
            window.location.hash = $(this).attr("href");
            return false;
        });
        $(window).bind('hashchange',function(){
            newHash = window.location.hash.substring(1);
            if(newHash){
                $mainContent.find("#guts").fadeOut('slow',function(){
                    $mainContent.hide().load(newHash + " #guts",function(){
                        $mainContent.fadeIn('slow');
                    });
                });
            }

        });
        $(window).trigger("hashchange");
    });

Answer 1

can do something like this

$(".nav").delegate("a","click",function(e){
       if (this.hash ){
           e.preventDefault();
            window.location.hash = $(this).attr("href");           
       }

      /* other links with no hash work normally*/
});
