[development] How can I refer to the shopping cart using document.getElementById if it does not have an id?

jQuery ships with Drupal. Use class-based selectors
http://api.jquery.com/category/selectors/

alert($(".pane-uc-cart-0").html());

However, if you are adding JS 'inline' it is added to the <head> which
executes before the rest of the DOM is loaded and so you won't get any
response. Use $(document).ready(function(){ ... }); or Drupal.behaviors.foo
= function() { ... } instead, or simply add it to the footer.
