Copy one tree to another tree

[Raketten1963]

Hi all,

I just recently started to use jstree, so I apologize if me questions are silly. I seasched the web as well as this group, but found nothing on the topic copy_node function.

I have a main tree, and I want to create an xact copy of this in a setup dialog, where I need to enable the checkbox plugin.

I use the function copy_node and I get an exact copy - that is great. However, the ids are different in my new tree, and I am having problems establishing a reference between the 2 sets of id's.

I found an old answer which tells me to do this

.on("copy_node.jstree", function(e,data){
   //top node
   data.instance.set_id(data.node, data.original.id); 
   //Children
   for(var i = 0, j = data.original.children_d.length; i < j; i++)
      data.instance.set_id(data.node.children_d[i], data.original.children_d[i]); 
})

Which make much sense but unfortunately does not work.

Both my tree's are using sort plugin, but I was told that children_d is not sorted in any way.

Does anybody have this code working, any ideas, or alternatives I am very appreciated.

Kind Regards Henrik

PS I attached a screenshot, the green ones are ok, but the rd ones are not....

PPS I made a Fiddle where ID is revealed on node click here

Hi all,

After a sleepless night, the obvious solution revealed itself in all it's simplicity.

The source tree already exist, so I can just grab the data and provide that to the destination tree upon creation.

      let data = [];
       let topnode = theTree.get_node(theNodeId);

       data.push({ "id" : topnode.id, "type" : topnode.type, "parent" : topnode.parent, "text" : topnode.text, state: {opened: true, }})
       for (let i=0; i < topnode.children_d.length; i++){
           let childnode = theTree.get_node(topnode.children_d[i]);
           data.push({ "id" : childnode.id, "type" : childnode.type, "parent" : childnode.parent, "text" : childnode.text})
       }

Just or even more easy and it works like it should....

KInd regards Henrik
