How do i check if the node is expanded in Kendo treeView

问题

I have a Kendo treeView. I want to collapse the node on single click (the default is on double click). To do that I need to know if the node is expanded already so I can call collapse(e.node). So, how do I check if the node has been expanded already?

Thanks a lot

回答1:

You can test with $(e.node).attr("data-expanded") === "true" or kendoTreeView._expanded(e.node), however if your goal is to collapse/expand depending on the current state, you can simply call

kendoTreeView.toggle(e.node);
