jQuery IF var = value or #id clicked

I have the .live aspect working now so if links are clicked, my function is executed, but I'm trying to figure out how include an option for a direct link to the content as well. Something like this:

$(showDiv).is('shipping-timeline')

or

$("#inm_if_hc_shipping_timeline").live('click', function() {

  [code to show and hide divs]            

});

showDiv contains the value that identifies the proper id, extracted from the URL.

My Question: How do I construct the IF statement to execute if either case is true?

Can anyone help? Thanks!

UPDATE:

So I took the IF parts from Graydot's answer and applied it to my code and here is a more complete example of what it looks like now:

$("#inm_if_hc_faq").bind('click', function(e) {

    if(showDiv == 'faq') {

            // prevent default behavior

            e.preventDefault();



            $("#inm_if_hc_content_faq").show("slow");   

            $("#inm_if_hc_content_shipping_timeline").hide("fast");

    }



        });

The most important part I was missing was having the default behavior and an IF that overrides it... thanks Graydot!

Now when the link is clicked, the div shows like it should, but not when the URL is entered.

Example: http://myurl.com/thispage.html?show=faq

I didn't include the function that populates the variable showDiv here, but I have verified in the console that it contains 'faq' as it should.

Anyone see what I am still missing?

Thanks!

FINAL UPDATE: SOLUTION

I didn't understand it at first, but the solution proved to be rethinking my approach. I appreciate that someone could see through my ignorance and came up with a great solution.

Here's the working code example:

$(window).bind('hashchange', function () { var hval = location.hash.slice(1);

if (hval == "faq") {

        $("#inm_if_hc_content_faq").show("slow");   

                    $("#inm_if_hc_content_shipping_timeline").hide("fast");

    }

});



$(document).ready(function() {



    $(window).trigger('hashchange');



});

With this, the link can be as simple as href="#faq" or from another page href="http://mydomain.com/mypage#faq" . No need to parse the URL for a variable or to use the IF statement to tell the difference between the nav link or an outside link.

Hope this helps someone else, so then I won't have to feel so ignorant! ;)
