[jQuery] trying to add a 'class' to a link based on the value of the link's href

[ksandness]

Hi there,

What I'm trying to do as add a 'selected' class to the current page
navigation link. I want to cycle through all the page links and if
'file' matches 'hrefs', add the class accordingly. Specifically, I'm
having problems with the last part of code below ---if (hrefs[i] ==
file) {$(this).addClass('selected');}---.  I can't seem to isolate the
matching link.
I no javascript pro, so I'm probably approaching this all wrong.

My code is below. The alerts are just there to make sure the variables
are storing the values I want.

               var file = jQuery.url.attr("file");
                alert(file);

                var hrefs = new Array();
                $('.design_html_nav li').each(function(){
                  hrefs.push($(this).find('a').attr('href'));
                });
                alert (hrefs[6]);

                for(i=0;i<hrefs.length;i++)
                {
                        if (hrefs[i] == file) {$('.design_html_nav li 
a').addClass
('selected');}
                }

Thanks, Kevin
