Questions that deal with code are generally better suited for the development list; nevertheless, here are some tips to get you started. :)

You first need a query that returns the block's markup independent of anything else. In your own custom module, you would probably have to write your own AJAX menu callback in hook_menu() which *prints* (or uses drupal_json) of the hook_block() markup from uc_cart.module.

In your module's hook_init() you use drupal_add_js() to load a JS file that would implement the setInterval when the document is loaded. The best practice for this is in JS is to leverage Drupal.behaviors, e.g.,

Drupal.behaviors.foo = function() { // setInterval stuff goes here to call AJAX menu callback specified in hook_menu(). }

Drupal.behaviors calls the specified function when the DOM is completely loaded (i.e. whenever Drupal.attachBehaviors is called). Check out Drupal.behaviors.password in modules/user/user.js for one such example.

Make sure you use proper access control in the hook_menu() callback. Also consider how this solution will scale.

I have a shopping cart block within the main pages that I want to refresh by calling the div called "panel-pane pane-block pane-uc-cart-0" every 2.5 seconds. What is the most efficient way to implement this?

I believe the way to call the javascript within drupal is by using the drupal_add_js() command but where do I put these commands so that the timer is run to refresh this shopping cart block every 2.5 seconds? I have seen some documentation that recommends using hook_init for javascript that is needed for all pages.

I believe that the timer is setup by running the command: *setInterval(shoppingCartInfo, 2500);* With shoppingCartInfo being a command that does a call to refresh the shopping cart block which could be a set of ajax calls or maybe command like *window.panel-pane pane-block pane-uc-cart-0.refresh().

Thanks,

John
