<!-- The next three functions have an hardcoded value. How do you figure out which value to use?
|
|
What is the id of a node?
|
|
If you are not using the node.xID capability, open the tree in the browser and move your mouse
|
|
over the +/- nodes to the left of the folders. The numbers shown are the ids of the folders.
|
|
Increment that number sequentially to get the ids of the "documents" inside that folder.
|
|
If you are using the node.xID capability, then simply use the corresponding xID value (it may
|
|
be a string).
