Client Script: Get/Change line items of quote

Client Script: Get/Change line items of quote

Hi,

the new "Client Script" feature seems to be a pretty good thing. So there are now finally possibilities to support the user during data entry. I just wonder how to do this in the Quotes module. Here it would be very helpful to query product properties at an OnChange event and to calculate prices based on various parameters and set them.

Specific questions:
How do I get a list of all line items?
How do I change individual items?

Regards,
Sven
