NodeTransfer.nodes介绍

[英]Obtain a list of nodes from a transferable. If there is only a single node in the transferable, this will just return a singleton array like #node. If there is a ExTransferable#multiFlavor (of at least one element), each element of which contains a node, then an array of these will be returned. If neither of these things is true, null will be returned.

This is a convenience method intended for those who wish to specially support pastes of multiple nodes at once. (By default, an explorer will fall back to presenting each component of a multiple-item transferable separately when checking for paste types on a target node, so if you have only one paste type and it makes no difference whether all of the nodes are pasted together or separately, you can just use #node.)

If you wish to test for cookies, you should do so manually according to your specific logic.
