Expand a tree path by sending the internalId as parameter

由 ぐ巨炮叔叔 提交于 2020-01-03 02:47:28
问题 Please consider the situation: I'm using Extjs' tree.Panel to have some sort of navigation on a page. I have a list of items in another portion of the page, whose list items have a unique id that matches the internalId of a node in the tree. I wish to bind a click for each list item and expand the tree to the node specified by the id on the item. I intend to use the expandPath(path) method from the tree. My question would be: how can I get the path string with just the internalId ? Thank you.
