[support] 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.

[Carl Wiedemann]

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.
