I’ve had the chance to write a custom module which allows me to use Ajax.updater to reload a specific block within a page (thanks for the help @Lee Saferite: http://www.magentocommerce.com/extension/933/modular-routers )
+ element is null
+ spConfig is undefined
+ optionsPrice is undefined
Here’s my Ajax.updater code getting called within a function onChange from any Attribute select:
//AJAX Update "refresh" of all product options
"<?php echo $this->getUrl('*/*/options', array('id' => $this->getProduct()->getId())); ?>",
I’ll post my findings here.
