    You are not comparing elements but jQuery objects (which are containers for elements);

    $("#footer") !== $("#footer")

    but

    $("#footer")[0] === $("#footer")[0]

    (Tests were ran on this page)

    So do this:

    $('#NavAContent li').toArray().indexOf( $('#A1')[0] );

    I removed some qualifiers hoping to god that you are not using multiple elements with same id.
