It seems the "data.inst" was renamed in newer versions to "data.instance". This made tracking down the solution difficult
似乎“data.inst”在较新版本中已重命名为“data.instance”。这使得追踪解决方案变得困难
data.instance.get_parent(data.node)returns the string ID of the parent (much unexpected for me). To get the parent I had to call data.instance.get_node()on the string ID.
data.instance.get_parent(data.node)返回父级的字符串 ID（对我来说很意外）。为了获得父级，我必须调用data.instance.get_node()字符串 ID。
data.instance.get_parent(data.node)is also accessible thru data.node.parent.
data.instance.get_parent(data.node)也可以通过 data.node.parent 访问。
Example:
例子：
$('#MaterialCollectionTree').on('activate_node.jstree', function(e, data) {
if(data.instance.is_leaf(data.node)) {
alert("Leaf: " + data.node.text);
alert("Parent: " + data.instance.get_node(data.node.parent).text);
}
});

It is a bit more complex then that
那就有点复杂了
parent_node = $.jstree._reference('#tree_id')._get_parent(n);
The variable parent_node is a jquery object so the command
变量 parent_node 是一个 jquery 对象，所以命令
parent_node.attr("something");
is the same as
是相同的
$("#parent_node_id").attr("something");
