Forced asynchronous loading child nodes of parent node. It is valid when [setting.async.enable = true]
You can use this method to reload child nodes.
Please use zTree object to executing the method.
The parent node which will asynchronous loading child nodes.
1. If parentNode = null, it is same as reload root nodes.
2. If parentNode.isParent = false, don't load nodes.
3. Please ensure that this data object is an internal node data object in zTree.
reloadType = "refresh" means: reload child nodes.
reloadType != "refresh" means: append to load child nodes.
Set whether to automatically expand the parent node, after load nodes.
isSilent = true means: don't auto expand the parent node. Otherwise auto expand.
no return value
