Select nav tab with jQuery based on id
===

I have a simple nav menu:

    <ul>
    <li><a href="index.php" id="home_menu">Home</a></li>
    <li><a href="purchase.php"  class="selected" id="information_menu">Information</a></li>
    <li><a href="purchase.php" id="contact_menu">Contact</a></li>
    </ul>

I am trying to set the correct menu item to be selected. Some of the menus will have sub menus so I don't think I want to do it by it's URL, so I have set a meta data tag in each page with the correct tabs' id:

    <meta name="selected_nav_tab" content="home" />

Then get the id via jQuery:

    $(document).ready(function () {
    
    //set appropriate nav menu to selected
    $('#nav li a').removeClass('selected');
    	
    //determine which tab should be selected
    var selected_tab = $('meta[name=selected_nav_tab]').attr("content");
    });

How can I use that id("var selected_tab") to select the home tab?

something like:

    $(#selected_tab).addClass('selected');


Probably a no brainer...


Thank you for bailing me out of my head again,
