jQuery if one statement is true and the other is not?

Right now I have a jQuery script that see's if .shipping has a descendant with a class of .sp-methods, and if it's true it will scroll down to the bottom of the page.

Current Working jQuery

if ($('.shipping .sp-methods').length > 0) {
        $('.shipping').show();
    $('html, body').animate({
        scrollTop: $(document).height() - $(window).height()
    },
    1400,
        "easeOutQuint");
}

Although what I want is the script to only run if that if that is true AND the element with an ID #shopping-cart does NOT contain the text "shipping" in it or any of its descendants. Just the text inside of something like this Shipping, not Shipping as a class or anything. Can contains do this?

I've tried this with no luck

Broken jQuery

if ($('.shipping .sp-methods').length > 0 && ! $("#shopping-cart:contains('shipping')")) {
    $('.shipping').show();
    $('html, body').animate({
        scrollTop: $(document).height() - $(window).height()
    },
    1400,
        "easeOutQuint");
}

That's because $("somethingNonExistent") is [] (an empty array). You need to check its length in order to know if the search for your selector was successful.

You should make the second condition follow the pattern of your first. So try checking the length of the second:

EDIT: Looks like you also missed a single quote for 'shipping', updated the answer with it inserted.

if ($('.shipping .sp-methods').length > 0 && $("#shopping-cart:contains('shipping')").length <= 0) {
  $('.shipping').show();
  $('html, body').animate({
      scrollTop: $(document).height() - $(window).height()
  },
  1400,
      "easeOutQuint");
}
