How to add ajax to customer sales order history to Magento 1.9


We have some customers that place a lot of orders (10 a day) and so their order history takes a long time to load. I am trying to add a date range filter to help them to find an order.

The problem I have is setting up the ajax so the date range is passed to the new phtml file (historytable.phtml) which just replaces the existing table.

Thanks. Any help gratefully received.
