enqueue jQuery into the footer

Question

I have looked but no where seems to cover how to place jQuery into the footer, at least not the way I have it in my theme, is there a way to place the following into the footer?

// Load jQuery
function my_register_jquery_function() {
    wp_deregister_script('jquery');
    wp_register_script('jquery', ("http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"), false, '1.7.1');
    wp_enqueue_script('jquery');

    wp_enqueue_script(
        'cookie'
        , get_stylesheet_directory_uri() . '/js/jquery.cookie.js'
        , array('jquery')
    );
    wp_enqueue_script(
        'easing'
        , get_stylesheet_directory_uri() . '/js/jquery.easing.1.3.js'
        , array('jquery')
    );
    wp_enqueue_script(
        'nivo'
        , get_stylesheet_directory_uri() . '/js/jquery.nivo.slider.js'
        , array('jquery')
    );
    wp_enqueue_script(
        'setup'
        , get_stylesheet_directory_uri() . '/js/setup.js'
        , array('jquery')
    );
}

add_action('wp_enqueue_scripts', 'my_register_jquery_function');

Answer 1

Sure. Set the fifth parameter of wp_enqueue_script or wp_register_script as true, and that script will be placed in the footer.

For example, your line

wp_register_script('jquery', ("http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"), false, '1.7.1');

should be

wp_register_script('jquery', ("http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"), false, '1.7.1', true);

And if you ever don't need/want to specify a version number, just set the fourth parameter to false.

By the way, to make sure you're avoiding any conflicts, I would recommend you prefix the names of all your custom scripts.
